Pulse monitors your entire heterogeneous infrastructure from one screen: Proxmox VE, Proxmox Backup Server, Proxmox Mail Gateway, Docker, Podman, Docker Swarm, Kubernetes, TrueNAS SCALE/CORE, VMware vSphere, and standalone Linux/Windows/macOS machines. The Go binary embeds a SolidJS/TypeScript frontend, delivering WebSocket-driven dashboards with sub-second metric updates on port 7655. A unified agent auto-detects Docker, Podman, Kubernetes, and Proxmox on each host without manual configuration and self-updates silently, while Proxmox nodes need only API credentials with zero agent installation. Smart alerts use adaptive hysteresis-based thresholds to prevent notification floods, pushing to Discord, Slack, Telegram, Teams, email, ntfy.sh, Gotify, and generic webhooks with per-resource overrides. The standout feature is Pulse Patrol: scheduled AI health checks running every ten minutes to seven days using OpenAI, Anthropic, Gemini, or local Ollama models. Patrol catches silent backup failures, capacity creep, restart loops, unhealthy containers, and clock drift that dashboards miss when nobody is watching. Platform-specific views render Proxmox nodes, Ceph clusters, Docker Compose projects, Kubernetes workloads, TrueNAS pools, and vSphere VMs in familiar layouts. OIDC, SSO, and SAML authentication with credential encryption at rest secures access. 6,500+ stars and 441 releases since February 2025.

Consistently ranked the most loved and most wanted database in developer surveys, PostgreSQL powers mission-critical workloads at Apple, Instagram, Spotify, and the U.S. Federal Aviation Administration with an architecture refined over nearly four decades since its origins at UC Berkeley. Its native JSONB type stores JSON in an indexed binary format with GIN and GiST index support, enabling document-store capabilities that eliminate the need for a separate NoSQL database in many architectures. The extension ecosystem exceeds 1,000 add-ons: PostGIS provides ISO-compliant geospatial queries, pgvector enables AI embedding similarity search, TimescaleDB adds time-series hypertable compression, and Citus distributes tables across nodes for horizontal scaling. PostgreSQL supports declarative partitioning by range, list, or hash, parallel query execution across multiple CPU cores, and four transaction isolation levels including full Serializable. Streaming replication provides physical standby servers with synchronous or asynchronous modes, while logical replication enables selective table-level change data capture through the Write-Ahead Log. Stored procedures run in PL/pgSQL, PL/Python, PL/Perl, and PL/V8 JavaScript, and advanced indexing includes B-tree, GIN, GiST, SP-GiST, BRIN, and hash types. Full-text search is built in with tsvector and tsquery, and row-level security policies enforce fine-grained access control.

Adopted by over 3,400 companies and backed by 34,000 GitHub stars, Backstage is the open-source developer portal framework created by Spotify and now hosted by the Cloud Native Computing Foundation. The centralized Software Catalog registers every service, library, data pipeline, website, and ML model in your organization using YAML metadata files stored alongside code in GitHub, GitHub Enterprise, or GitLab, tracking ownership, lifecycle status, and dependency relationships across your entire ecosystem. Software Templates provide self-service infrastructure provisioning where developers fill out a form and Backstage automatically scaffolds new repositories, CI/CD pipelines, and cloud resources following your organization's standardized best practices. TechDocs renders Markdown documentation directly alongside the services it describes using a docs-like-code approach powered by MkDocs, with the TechDocs Addon Framework for extending the reading experience. The Search Platform indexes content across the catalog, TechDocs, Confluence, and Stack Overflow through configurable search backends. Kubernetes monitoring built specifically for service owners rather than cluster admins displays pod health, logs, and deployment status across any cloud provider or managed Kubernetes service. The plugin ecosystem includes over 230 open-source integrations covering CI/CD systems like GitHub Actions and GitLab Pipelines, monitoring platforms like Datadog and Grafana, cloud providers including AWS and Azure, plus specialized plugins for security scanning, cost management, API documentation, PagerDuty incident management, and Lighthouse website auditing.

ToolHive is an open-source MCP server management platform that lets you run, secure, and orchestrate Model Context Protocol servers in isolated containers, giving AI agents structured access to tools like GitHub, databases, and cloud services without exposing host credentials or network. Every server launches inside its own sandboxed container with a minimal permission file, network access filtering, and encrypted secrets management, preventing misbehaving connectors from reaching beyond their defined scope. The built-in registry provides a catalog of vetted servers you can install with one command, while custom images and package-manager references let you onboard proprietary connectors without writing Dockerfiles. Platform teams deploy the Kubernetes operator to declare MCP servers as cluster resources using Custom Resource Definitions, with automated lifecycle management and multi-namespace isolation. The Virtual MCP Server gateway aggregates multiple backends behind a single endpoint, centralizing OIDC authentication, tool filtering, and composite cross-server workflows so clients connect once instead of juggling separate URLs. An MCP Optimizer analyzes tool schemas via semantic search and surfaces only relevant tools per request, cutting token consumption by up to 85%. OpenTelemetry traces and Prometheus metrics deliver full visibility into tool execution, latency, and request audit trails across every managed server.

Trusted by thousands of organizations processing billions of time series data points and backed by 17,000+ GitHub stars, VictoriaMetrics delivers a monitoring and time series database that outperforms Prometheus by 16x on query speed while consuming 2.5x less disk space through its optimized compression and storage engine. The architecture supports both single-node deployments handling 10M+ active time series and a horizontally scalable cluster version with vminsert, vmstorage, and vmselect components providing multi-tenancy, replication, and independent namespace isolation. Data ingestion accepts both push protocols including InfluxDB line protocol, Graphite plaintext, OpenTSDB HTTP, CSV, and OpenTelemetry OTLP alongside pull-based Prometheus scraping and remote write, enabling drop-in replacement of existing monitoring stacks without reconfiguring exporters. MetricsQL extends standard PromQL with additional functions, subqueries, and implicit time range alignment while maintaining full backward compatibility with existing Prometheus alerts and Grafana dashboards. The vmalert component processes recording and alerting rules with Alertmanager integration, while vmbackup and vmrestore enable point-in-time snapshots to S3, GCS, and Azure Blob Storage. Stream aggregation operates as a StatsD alternative for pre-aggregating high-cardinality metrics before storage. NFS-compatible storage backends including Amazon EFS and Google Filestore allow shared persistent volumes across cluster nodes.

VyManager puts every VyOS router you run, across every site, into one web control plane with live dashboards and per-site permissions. Organize instances into logical sites, from the datacenter core to the smallest branch office, and add or remove routers without touching a command line. Live dashboards stream interface counters, system information, network graphs, and WireGuard peer status, so a saturated link announces itself before your users do. Configuration adapts to each router's VyOS version, with 1.4, 1.5, and rolling releases supported side by side during the longest upgrade cycle. Access is granted per site with OWNER, ADMIN, and VIEWER roles, API keys authenticate the machines, and SSH credentials stay encrypted at rest. A setup wizard walks a fresh deployment to its first managed router, and light, dark, and custom themes keep the night shift comfortable. For automation, AI assistants can be connected through the companion MCP integration, and the whole stack arrives as Docker Compose services you can redeploy in minutes. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

Keep every VPS, home-lab box, NAS, and router you run on one self-hosted dashboard, with a small agent on each machine reporting whether it is up and how hard it is working. Nezha tracks CPU, memory, swap, disk, load, traffic, process counts, and TCP and UDP connections on Linux, Windows, macOS, OpenWRT, and Synology machines, plus GPU and temperature where supported. Servers sort into groups and appear as cards, a list, or a world map, with live charts and, when the optional time-series database is on, 1, 7, and 30 days of history. HTTP GET, ICMP Ping, and TCPing monitors run from the servers you choose, chart latency and packet loss, and warn about HTTPS certificate changes and upcoming expiry. Alert rules watch offline servers, resource use, bandwidth, and cycle traffic limits, then message Telegram, Slack, Matrix, Feishu, DingTalk, or any webhook. A browser terminal and file manager handle quick fixes, while scheduled or alert-triggered tasks run backups, restarts, and scripts across many servers. DDNS updates Cloudflare, Tencent Cloud, or Hurricane Electric records when an agent's IP changes, and NAT traversal publishes a home router or NAS page on your own domain. Admin and user roles, scoped API tokens, and an optional MCP endpoint let people and AI tools list servers and run commands within their permissions.

Dockhand is a Docker management platforms, offering a modern alternative to Portainer with free OIDC SSO and vulnerability scanning that competitors gate behind paid tiers. Real-time container management provides start, stop, restart, and remove operations with live resource monitoring across CPU, memory, and network usage on a dashboard with real-time metrics. The visual Docker Compose editor enables stack creation and modification with syntax highlighting, while Git integration deploys stacks directly from repositories with webhooks and auto-sync for GitOps workflows. Vulnerability scanning powered by Grype and Trivy analyzes container images against CVE databases, with configurable auto-update scheduling that can trigger updates based on vulnerability severity criteria. The Hawser Go agent enables management of remote Docker hosts in Standard mode for LAN environments or Edge mode using outbound WebSocket connections for hosts behind NAT, firewalls, or dynamic IPs without exposing inbound ports. Interactive terminal sessions provide shell access into running containers, while the file browser enables uploading, downloading, and editing files directly within containers. Image management includes registry browsing, pull operations, and layer inspection alongside network and volume administration. The security-focused architecture builds its own OS layer from scratch using Wolfi packages via apko with every package explicitly declared.

Routerly is the one front door for every AI model your apps use: point your OpenAI or Anthropic client at it, and it chooses the right model for each request, enforces your budget, and keeps the receipts. Nothing in your code changes except the base URL, and from that moment streaming chat completions and messages flow to OpenAI, Anthropic, Gemini, Mistral, Cohere, xAI or your own Ollama models behind a single token. Nine routing policies score every candidate in parallel: cheapest, fastest, healthiest, most capable, biggest context, least rate-limited, fairest, most budget left, and one that asks a small model to judge which model fits the task. When the winner errors or times out, the next candidate takes over automatically, and the recorded routing trace shows exactly why each model won or lost. Guardrails can block or log content that breaks your rules, and phone numbers, card numbers, SSNs, IBANs and emails can be scrubbed out before anything reaches a provider. Every call is logged with tokens, USD cost and latency, and hard limits per model, project and token reject overspending requests before a provider can charge for them. Projects keep separate tokens, model lists and budgets for each team or tool, role-based permissions decide who may change what, and alerts land in Slack, email, webhooks or PagerDuty when budgets or providers misbehave.

Every service you self-host wants its own account database, and Kanidm exists so they can all share one: one identity server where people sign in with passkeys and every application trusts the same login. Users register YubiKeys, Touch ID, Windows Hello, or TPM backed authenticators, and attested passkey policies let administrators restrict sign-in to specific authenticator models in high security environments. Applications connect as OAuth2 or OpenID Connect clients with authorization code, client credentials, PKCE, token exchange, and revocation supported, so your wiki, Git forge, and file sync all delegate sign-in instead of storing passwords. The application portal gives each person one page of tiles for every service they may open, and role based access control decides which groups see which applications and scopes. Older systems that only speak LDAP bind to the read-only LDAPS gateway, while Wi-Fi and VPN gear authenticates through the built-in RADIUS server with MS-CHAPv2 and EAP-TLS. Linux machines join through the Unix client for PAM and NSS authentication, cached offline credentials protected by the machine TPM, and SSH keys distributed from the server to every host. A second server replicates the whole database with strong eventual consistency, every node accepting writes without elections or quorums, so a failed machine never locks your users out of sign-in.

Your racks of hypervisor hosts become one private cloud with Apache CloudStack, the open-source IaaS platform that deploys and manages large networks of virtual machines behind a single web interface and API. One cloud can mix hypervisors side by side, running KVM, XenServer or XCP-ng, and VMware vSphere clusters under the same control plane, each organized into regions, zones, pods, and clusters that mirror your physical datacenters and racks. Administrators provision instances from templates and ISO images, take volume and VM snapshots on schedules, and migrate running instances between hosts in a cluster without downtime. Built-in networking spans isolated and shared networks, VPCs with tiered virtual routers, load balancers with SSL offloading, VPNs, and firewall rules, all exposed both to admins and to end users through separate, customizable interfaces. Multi-tenancy is native: domains, accounts, usage metering, and resource quotas let providers bill departments or customers for what they consume. The 4.22 LTS release strengthens backup and disaster recovery, adds a CSI driver for CloudStack Kubernetes Service, and streamlines VMware-to-KVM migrations for teams consolidating onto open virtualization.

Transactions, analytics, full-text search, and vector retrieval stop needing four separate systems: MatrixOne folds them into one hyper-converged database engine that speaks the MySQL 8.0 wire protocol, so existing drivers, JDBC applications, Navicat, and BI tools connect unchanged. A single TAE storage engine serves OLTP and OLAP together, with compute and storage separated so query nodes scale independently of the data they scan. Vector columns carry IVF and HNSW indexes with L2, cosine, and inner-product distance, powering RAG and semantic search at billions scale beside your relational tables instead of in a sidecar database. Full-text indexing joins the same query, so hybrid searches combine keyword relevance and embedding similarity in one statement. Git-style version control for data lets teams clone, branch, and roll back datasets the way they already treat code, which makes experiments and audits reproducible. Streaming ingestion through Kafka connectors keeps analytical tables current, and the 4.2 line sharpens window-query performance, composite-index planning, and physical backup and restore that preserves table history.

Four hundred servers need a security patch, they run five different Linux distributions, and a spreadsheet says which ones were done. Uyuni replaces that spreadsheet: one server inventories your fleet, mirrors the software channels each machine subscribes to, and shows exactly which patches and errata apply where. Administrators register clients manually, by bootstrap script, or automatically through activation keys, then group them into systems sets so an action aimed at a group lands on staging first and production on schedule. Patch management creates and applies errata with CVE context, and CVE audits check systems against vulnerability data so you can prove a fix landed instead of believing it did. Configuration channels push files, directories, and symbolic links rendered with Jinja templates through the built-in Salt master, which also runs remote commands and orchestration across tens of thousands of clients. The Content Lifecycle Manager promotes package sets from development through testing to production channels, so every environment consumes tested content in order. Provisioning reinstalls or network-boots machines through PXE with AutoYaST, Kickstart, or cloud-init profiles, proxies cache content for branch offices, and built-in Prometheus and Grafana monitoring watches the management server itself.

When a ClickHouse cluster slows down, the answers are buried in system tables nobody wants to query by hand; CHMonitor turns those tables into an operations dashboard that explains what the cluster is doing and what to fix next. Live views cover running queries with elapsed time, memory, and a kill action, while history, failed, slowest, and most-expensive pages rank finished work by CPU, duration, and rows read, each with the full statement and one-click EXPLAIN. Thread-level analysis shows how a single query parallelized, and per-user summaries reveal which analyst or service is eating the cluster. Beyond queries, you get a merge and part-lifecycle timeline, replication queue and Keeper health, a live topology map of shards and replicas, storage breakdowns by database, table, and part, and a query activity heatmap spanning a year. An AI advisor reviews the workload and recommends skip indexes, projections, PREWHERE clauses, and TTL changes ranked by impact, with an MCP interface and built-in agent for asking questions in plain English; it recommends only and never applies DDL. Threshold-based health checks alert to Slack, Discord, PagerDuty, or Opsgenie, multiple ClickHouse hosts are watched from one dashboard, and a companion terminal UI covers quick checks from the shell.

Achieving 98.4% Recall@5 on LongMemEval-S without a reranker, AKB is the agent-native knowledge infrastructure giving Claude Code, Cursor, Windsurf, and any MCP-aware agent persistent organizational memory — a drop-in replacement for Confluence or Notion where AI agents read and write directly rather than scraping human-formatted pages. Documents are stored as Markdown with YAML frontmatter in Git bare repositories (full version history, branching, diff), while PostgreSQL 16 serves as source of truth for chunk text, metadata, and BM25 vocabulary, with dense embeddings handled by a pluggable vector store (pgvector default, Qdrant optional, or managed Seahorse). Agents interact through 20+ MCP tools — akb_put, akb_search, akb_browse, akb_relations, akb_sql, akb_edit, akb_history — performing hybrid dense plus BM25 search fused via Reciprocal Rank Fusion in one call. The URI graph (depends_on, related_to, implements relations) lets agents traverse knowledge connections without external graph databases. Multi-tenant vault isolation is enforced at the PostgreSQL ACL level with per-user roles and SET LOCAL ROLE for SQL sandboxing. Event fanout streams structured events to Redis Streams for external consumers (synthesis bots, digest agents, audit trails), and a hash-chained append-only audit log integrates with enterprise SIEMs. Ships with agent plugins for Claude Code and Codex (session capture, wiki ingest, lifecycle hooks), Kubernetes kustomize manifests, and Open Knowledge Format export.

BSL 1.1 licensed (free under 100 seats, auto-converts to Apache 2.0 after four years).

Powering notification delivery for thousands of organizations with over 39,000 GitHub stars, Novu is the open-source communication infrastructure that eliminates the need to build separate integrations for every messaging channel. The TypeScript-based platform provides a single API endpoint that routes notifications across In-App Inbox, Email via SendGrid, Mailgun, AWS SES, and Postmark, SMS through Twilio, Vonage, and Plivo, Push via Firebase Cloud Messaging, Expo, and APNS, and Chat through Slack, Discord, Microsoft Teams, and WhatsApp. The embeddable React Inbox component delivers real-time WebSocket-powered notifications with read/unread states, action buttons, and user-controlled preferences directly inside your application. The workflow engine orchestrates complex multi-channel delivery with conditional branching, time delays, digest batching to reduce notification fatigue, throttle controls, and per-step channel fallbacks. Novu Connect introduces Agent Communication Infrastructure enabling AI agents built with LangChain, Claude, or custom frameworks to hold threaded two-way conversations with humans across any supported channel through a single conversation model with identity resolution and credential management. The backend runs on Node.js with NestJS, MongoDB for notification storage, Redis with BullMQ for job queuing, and Socket.io for real-time delivery. Self-hosting deploys via Docker Compose with the dashboard accessible at port 4200.

Type one command on the Salt master and ten thousand machines answer, because Salt publishes jobs to minions that subscribe, check whether the job targets them, and execute it in parallel before reporting results back. Configuration management describes the desired end state in YAML state files: which packages, files, services, and users should exist, and highstate runs converge every targeted minion toward that description with dependency ordering. Targeting goes far beyond hostnames, since grains describe each minion's operating system, hardware, and roles, and Pillar delivers per-minion secrets and settings rendered only for the machines that should receive them. Beacons watch services, load, disks, logins, and file changes on minions and emit events onto the bus, while reactors bind those events to prepared responses, so a failed service can restart itself and an administrator gets notified with the evidence attached. Orchestration runners coordinate multi-machine procedures in sequence, such as draining a load balancer pool, patching it, and returning it to service, and the master exposes HTTP APIs and pluggable returners that stream job results into your databases and dashboards. Machines that cannot run an agent are reached through Salt SSH, and Salt Resources target appliances and API endpoints that should be managed without a minion at all.

A single GPU can only hold so many models at once, and when a chat server, an image pipeline, and a voice engine all grab VRAM together, somebody runs out of memory and crashes. Berth fixes the scramble by making every engine lease the card: wrap a launch in berth run and the daemon grants memory in turn, queues the rest with an honest place in line and a start estimate, and drains a holder cleanly before the next load begins. The broker learns each engine's real footprint from its runs, so grants are sized by measured peaks instead of guesses, and processes that grab memory without a lease are reported as stowaways, never killed, with contested grants flagged in plain sight. A collisions board counts what the scheduling prevented: avoided collisions, VRAM handed off, drains, stuck releases, and refusals, and every count links back to a gap free event log you can follow live. The Harbor web UI turns that into a departures board of leases, a six hour tide of memory by holder, engine cards with decode throughput and a token ledger, plus a per model leaderboard and thirty days of stored history. Alerts reach your desktop or a webhook, Prometheus scrapes the metrics endpoint, and multi GPU machines can even pass one card through to a VM while the others keep serving.
