When an alert fires on any of your Prometheus Alertmanagers, Karma shows it once, on one filterable dashboard, and lets you acknowledge or silence it from there. Identical alerts from different servers merge into one entry tagged with every server that saw it, HA pairs included. Groups follow the group_by settings of your Alertmanager routes, and shared labels and annotations collapse into a footer. Multi-grid mode gives each value of a label, or each Alertmanager, cluster, or receiver, its own grid, keeping production and staging apart. Configurable label colors make hosts and severities easy to spot. Optional history draws 24 hourly blocks per group from the Prometheus servers that fired it, and an inhibited alert's muted button lists whatever is suppressing it. One click acknowledges an alert with a short-lived silence, and the separate kthxbye daemon can keep extending it until the alert resolves. The silence modal creates, edits, and expires silences, and ticket IDs in comments can become links. A Dead Man's Switch check raises a visible error when the alerting pipeline goes quiet. Basic auth or a proxy's header identifies each user, silence ACLs stop one team from silencing another's alerts, and read-only mode disables silence management. Default filters open the view your team triages first, and light and dark themes follow the browser.

Spreadsheets deserve an engine that anyone can embed, audit, and run on their own server. IronCalc is an open-source spreadsheet engine with a browser editor that reads and writes real Excel files: open an xlsx, edit values and formulas in the grid, format cells, and save the workbook back without a round trip through a proprietary suite. The grid feels familiar on purpose, with a formatting toolbar for fonts, fills, borders, number formats, and alignment, sheet tabs along the bottom, and templates for invoices, expense trackers, calendars, timesheets, and project plans so a new workbook starts from structure instead of a blank page. Files import from xlsx and export again to the same format, which keeps IronCalc honest as a working tool instead of a viewer. Underneath, the calculation engine is a library other software can call, so the same formulas that evaluate in your browser can also run inside a Python script, a Node service, or a WebAssembly build embedded in your own product. Self-hosting puts the whole webapp behind your own address: one Docker Compose brings up the spreadsheet server with its proxy, and teams share workbooks from infrastructure they control rather than uploading budgets to a stranger's cloud.

Testing a migration against a toy database proves almost nothing. Database Lab Engine is an open-source platform that clones production-sized PostgreSQL databases in seconds, giving every developer, CI job, and query experiment a full-fidelity copy without waiting hours for a restore or paying to store ten of them. The trick is thin cloning: copy-on-write snapshots taken on ZFS or LVM let a one-terabyte database materialise as a writable branch in about ten seconds, with dozens of independent clones sharing one physical dataset until their changes diverge. Teams point CI at a fresh clone for every migration, so 100 percent of schema changes get rehearsed against real data shapes and volumes before they touch production; analysts get disposable copies for testing query rewrites and index ideas; and a bad experiment costs one delete, not one restore. Clones are managed through a web UI, API, and CLI, draw from self-managed Postgres or managed sources on RDS, Cloud SQL, and Supabase, and carry popular extensions in their containers. Resets, upgrades, deletion protection, retention rules, and resource quotas keep the fleet tidy as it grows into branches and snapshots numbering in the dozens.

FileBrowser Quantum is an open-source, self-hosted web file manager that transforms any directory tree or mounted storage volume into a fast, searchable cloud drive accessible from any browser. You can mount multiple independent filesystem sources at once and apply custom include or exclude rules to keep sensitive system folders hidden from everyday browsing. A background indexing engine powers instant as-you-type search across millions of files, letting you filter results by file size, folder size, media type, or modification date in milliseconds. Rich media thumbnails render automatically for videos, office documents, audio album artwork, and interactive 3D models, while integrated OnlyOffice support lets you edit spreadsheets and word processing documents directly inside your browser tab. Built-in WebDAV server support allows desktop operating systems and mobile file apps to mount your remote directories as native network drives. Sharing files with external collaborators takes seconds through customizable public or private links with expiration timers, download limits, password protection, anonymous upload permissions, and custom branding themes. Administrators can authenticate users via OpenID Connect, LDAP, JSON Web Tokens, proxy headers, or local passwords with two-factor authentication, then enforce path-level read, write, and delete rules per user or group. Developers and automation engineers can generate long-lived API tokens and explore the interactive Swagger endpoint to script file transfers and directory provisioning.

With over 30,000 GitHub stars and benchmarks showing 25x the throughput of single-threaded Redis, DragonflyDB is a modern in-memory data store that eliminates the need for complex Redis Cluster deployments by fully utilizing every CPU core on a single machine. Its shared-nothing, thread-per-core architecture written in C++ supports over 200 Redis commands and 13 Memcached commands, making it a true drop-in replacement that requires zero application code changes. A single DragonflyDB instance scales vertically from 8GB to 768GB of RAM across up to 64 cores, replacing entire Redis Cluster topologies with one process while maintaining full compatibility with Strings, Hashes, Lists, Sets, Sorted Sets, Streams, JSON, and Bloom Filters. The novel dashtable data structure and cache eviction algorithm achieve higher hit rates than LRU and LFU with zero memory overhead per entry. Forkless point-in-time snapshotting eliminates the memory spikes associated with Redis BGSAVE, while automatic backup scheduling via cron syntax supports both local disk and AWS S3 cloud storage. Primary-replica replication follows the Redis replication protocol up to version 6.2, and Prometheus-compatible metrics at the default port enable Grafana monitoring dashboards out of the box. DragonflyDB also exposes an HTTP admin interface on its main TCP port for operational monitoring.

Files belong to the project, not to whoever uploaded them: ownCloud Infinite Scale is a self-hosted file sharing and collaboration platform where teams work in Spaces, data rooms that stay intact when people join, leave, or change roles. Inside a Space, members browse, upload, version, and share files from the web interface or synced clients, with full control over links, permissions, and expiry. Documents open for real-time editing through the web office integration of your choice, favorites and recent files keep daily work one click away, and full-text search with tags finds content across every Space you can access. Personal files live alongside team Spaces, a recycle bin catches mistakes, and administrators manage users, groups, roles, and storage from the same deployment. One service runs the whole platform for a home server, and the same system scales out for schools, companies, and public institutions that must keep data on their own infrastructure.

Quackback unifies customer feedback boards, feature voting, public roadmaps, release changelogs, help centers, status pages, and a multi-channel support inbox into a single self-hosted workspace that replaces Canny, Productboard, and Intercom. Product teams use its branded boards to collect feature requests and bug reports, merge duplicate submissions, and rank demand by user votes or customer segments. When a request moves into development, two-way integrations with Linear, GitHub, and Jira automatically update the card across customizable Kanban status columns or quarterly timeline views on your public roadmap. Support agents work out of a shared inbox that brings real-time Messenger web chat, inbound email threads, and durable support tickets together under one roof, complete with SLA timers, office hours, saved macros, and CSAT surveys. Conversations that uncover a feature gap convert directly into votes on existing feedback posts without losing thread context. Quinn, the built-in AI assistant, answers common questions from your Help Center articles, drafts agent replies, and exposes a Model Context Protocol server so external AI tools can triage posts or manage tickets. Once features ship, publishing a scheduled changelog entry automatically notifies every voter via email and in-app alerts.

Every AI agent that deals with people eventually needs an email address, and Open Agent Email gives each one a real inbox on your own domain. Agents receive mail in proper threads, reply in place, send new messages, schedule sends up to 90 days ahead, and handle attachments, labels, search, trash and restore from one mailbox. A human approval gate can hold any outgoing message until a person clicks approve or reject, with an expiry and a full history, so a risky reply never reaches a customer unchecked. Incoming mail is screened for prompt-injection tricks and hidden text, checked against SPF, DKIM, and DMARC, and can be scanned for viruses before an agent reads it. Agents connect through a REST API with an OpenAPI file, dependency-free Python and TypeScript SDKs, the oae command line, signed webhooks, a live WebSocket stream, or 96 MCP tools for coding agents. The browser dashboard covers guided setup, inboxes, pending approvals, the outbox queue with retries, delivery metrics with bounce and complaint tracking, contacts, templates, domains with DNS verification, and API keys. Sending runs through your own relay, SES events feed suppression lists automatically, and scoped per-inbox keys limit what each agent may do.

With 2,400+ GitHub stars, HolyClaude replaces a two-hour manual setup process with a single docker compose up command that launches a fully configured AI coding workstation. The container ships with Claude Code pre-installed alongside seven additional AI CLIs — Gemini CLI, OpenAI Codex, Cursor, TaskMaster AI, Junie, OpenCode with OpenRouter multi-provider support, and Pi Coding Agent — all accessible through the CloudCLI browser-based web interface on port 3001. A headless Chromium browser running on Xvfb display :99 comes pre-configured with Playwright 1.61 for automated screenshots, testing, and web scraping without additional setup. The development toolchain includes Node.js 26, Python 3, TypeScript, git, GitHub CLI, database clients for PostgreSQL, SQLite, and Redis, plus deployment CLIs for Vercel, Wrangler, Netlify, and Azure. Process management uses s6-overlay for automatic restarts and graceful shutdown, while bind mounts to ./data/claude and ./workspace ensure credentials, configuration, and project files persist across container rebuilds. The full image supports AMD64 and ARM64 architectures, running on Linux, macOS with Docker Desktop, Windows with WSL2, and Synology or QNAP NAS hardware. A slim tag at roughly 2GB omits the browser stack for environments that do not need it, while the full image at 4GB includes everything. Users authenticate with their existing Anthropic account directly through Claude Code with no credential relay or proxy involved.

Tidarr turns a Tidal subscription into a personal music archive you control, downloading tracks, albums, playlists, mixes, and music videos at up to 24-bit 192 kHz FLAC quality. Search by keyword or paste an artist, album, playlist, track, or mix URL, then queue downloads that are processed on the server and filed into your library folder. Playlists, mixes, favorites, and artists can be watched and synced on a schedule, existing tracks are skipped, and covers and M3U playlist files are generated with customizable paths. Optional OpenID Connect or password protection secures the interface on port 8484, and the quality selector can be locked for shared instances. Downloaded releases are tagged on the fly by Beets, custom shell scripts can run in the post-processing pipeline, and finished additions trigger library refreshes in Plex, Jellyfin, or Navidrome. Completion notifications arrive through Gotify, Ntfy, Apprise, or a Mattermost webhook. Lidarr can use Tidarr as both a Newznab indexer and a SABnzbd download client, folding high-quality acquisition into an existing monitored library workflow. ReplayGain values, download history, rate-limited modes, and custom CSS round out daily use, and a REST API exposes the same functions to external automation.

A PostgreSQL database becomes a production-grade GraphQL API the moment Hasura GraphQL Engine points at it: track tables and relationships - existing schemas included - and full query, mutation, and subscription types appear with where, order_by, limit, offset, and on_conflict arguments, no resolvers or boilerplate written. Its Haskell core compiles GraphQL to efficient SQL, and any query becomes a real-time live query with a single keyword, powering dashboards and collaborative UIs over standard GraphQL subscriptions. Authorization is where Hasura earns its enterprise reputation: role-based access control with row- and column-level permission policies driven by session variables from JWTs, auth webhooks, or headers - each role effectively sees its own GraphQL schema containing only what it may touch, integrating cleanly with Auth0, Firebase, or homegrown auth. Event triggers fire webhooks on inserts, updates, and deletes for asynchronous business logic; Actions extend the schema with custom REST handlers; remote schema stitching merges external GraphQL services into one endpoint; and auto-generated REST endpoints serve clients that skip GraphQL. A browser console handles data modeling and API exploration, the CLI manages migrations and metadata as code, and deployment is a single stateless Docker container beside Postgres.

Manga, comics, ebooks, and light novels get a streaming-service-style home in Kavita - a fast, cross-platform reading server for the DRM-free collection you share with family and friends. It natively serves CBZ, CBR, CB7, ZIP/RAR/7z archives, raw images, EPUB, and PDF, with hand-crafted web readers per format: webtoon scrolling, single and dual-page spreads with advanced caching for the comic reader, and a book reader with adjustable fonts, spacing, margins, color themes, and column modes. Reading progress tracks per user, so everyone resumes exactly where they stopped on any device. Metadata parses from filenames, ComicInfo.xml, and EPUB fields, feeding index-backed search, smart filters, collections, reading lists with CBL import, and Want to Read queues. Role-based user management covers age restrictions, per-library access, and OIDC authentication. An OPDS feed connects third-party clients - Panels on iOS, Librera on Android, KOReader on e-ink devices - and a comprehensive REST API supports custom integrations. EPUB annotation and highlight support, custom theming, and full localization round it out. Built with .NET and Angular, it handles 50,000+ file libraries without strain; optional Kavita+ adds AniList scrobbling, recommendations, and external metadata.

With over 45,000 GitHub stars and 100 million Docker pulls, Milvus is the most widely adopted open-source vector database, powering production AI systems at NVIDIA, Salesforce, eBay, Airbnb, and DoorDash. The distributed architecture separates compute and storage with stateless microservices on Kubernetes, horizontally scaling query nodes for read-heavy workloads and data nodes for write-heavy ingestion independently. Milvus 3.0 introduces lake-native retrieval that builds and serves indexes directly over vector data in object storage and open formats including Parquet, Lance, Iceberg, and Vortex without maintaining separate copies. Native hybrid search unifies lexical BM25 full-text retrieval and semantic vector search in a single engine with metadata filtering, eliminating the need for separate search infrastructure. Hardware-accelerated ANN indexing supports IVF, HNSW, DiskANN, and GPU-based indexes with BitQ 1-bit quantization cutting memory usage by 72 percent. SDKs for Python, Go, Node.js, and Java provide programmatic access, while Milvus Lite offers lightweight embedding for local development via pip install. Server-side aggregation, sorting, faceted search, StructArray for nested document structures, and ColBERT multi-vector scoring move ranking and result processing into the engine. The Path Index enables 100x faster JSON filtering with support for 100,000+ collections per cluster for multi-tenant deployments. Self-hosting deploys via Docker Standalone or Kubernetes with Helm charts using S3-compatible, GCS, or Azure Blob storage backends.

A dropped connection should not restart a 20 GB upload: SnowShare is a self-hosted app for sharing files, links, and pastes, with resumable transfers and an expiry date, a view limit, a password, and a QR code available on every share. Put several files into one share and let recipients preview common formats right in the browser, shorten a long address with an optional custom slug, or publish text and code with syntax highlighting. People you send a link to can open it with or without an account, depending on how you configure the instance. Give your users email and password accounts or OAuth sign-in, turn on email verification and CAPTCHA, and set separate storage quotas for anonymous visitors and registered users. Keep uploads on local disk or move them to S3-compatible storage, apply your own branding, and change quotas, sharing rules, SMTP, and storage from the admin panel without restarting. Automate sharing through the REST API with keys created from your profile, drop the generated ShareX uploader files into your capture tool, and receive signed webhook events when shares are created, opened, or deleted. Read the interface in English, French, Spanish, German, Dutch, or Polish, and let expired shares clean themselves up every hour.

TYPO3 lets an organization run any number of multilingual websites from one installation, with editors working in a page tree and administrators deciding who may touch what. Editing happens in a context panel that slides in beside the page layout, and a guided wizard creates new pages step by step. Translations can be copied or connected to their source with change tracking, and sites can mix languages, including right-to-left scripts. Workspaces keep edits away from the live site until they are previewed and approved, while access lists, page permissions, and mounts control which parts of the tree each backend user may change. Marketing teams get a QR code module and a short URL module with hit counters and expiry dates, and redirects are created automatically whenever a page slug changes. The Form Framework builds forms with multiple file uploads in one field, CKEditor 5 text editing, and email notifications customized in the backend. A dashboard shows widgets such as recent documents and backend logins, and a Bookmark Manager groups shortcuts into large page trees. The Camino starter theme gives integrators a ready-made frontend with several color schemes, and developers shape sites further with Fluid templates and TypoScript, plus extensions from extensions.typo3.org.

Filestash puts a Dropbox-style web interface in front of the SFTP servers, S3 buckets, SMB shares, and WebDAV storage you already run, so no file has to move. Administrators enable each connector, including FTP, NFS, Git, Dropbox, Google Drive, Storj, IPFS, and Backblaze B2, from one admin console. Colleagues browse, rename, move, and upload in a single folder view, with resumable uploads for big transfers. Thumbnails cover JPEG, PNG, WebP, TIFF, HEIF, and RAW photos. Images open with an EXIF info panel, and PDFs, audio, video, and EPUB ebooks open right in the browser. A CodeMirror editor handles text and code, and HLS transcoding streams video on demand. Outside guests get a shared link instead of credentials, with an optional password, an expiry date, and read, write, or upload-only rights. Limit a link to one email address or a whole domain, or mount it as a network drive. A workflow engine chains emails and HTTP calls after file events, webhooks, or schedules. Flip one admin setting and Claude, ChatGPT, and Mistral Le Chat can use the connected storage as MCP tools. Downloadable file apps add Office documents, 3D models, and GIS maps. Runtime plugins are zip files dropped into the plugins folder. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Agenta delivers a comprehensive open-source LLMOps workspace that covers the full lifecycle of AI application development — from prompt engineering through production monitoring. The platform supports 15+ model providers including OpenAI, Anthropic, Google Gemini, Mistral, Groq, Together AI, Azure, AWS Bedrock, and self-hosted models via Ollama, enabling teams to switch between providers without code changes. The prompt playground allows side-by-side comparison of different configurations, while the evaluation system offers LLM-as-a-Judge assessment, 20+ pre-built evaluators covering semantic similarity, regex matching, and factual accuracy, plus custom Python evaluators for domain-specific requirements. Teams run evaluations through both the web UI for subject matter experts and the Evaluation SDK for programmatic CI/CD integration. The observability layer captures full trace visibility across complex agentic workflows, flagging quality issues like hallucinations and off-topic responses in real time. Human annotation workflows let domain experts review and annotate LLM outputs, feeding corrections back into the evaluation loop. The architecture supports Chain of Prompts, RAG pipelines, and multi-step agent workflows, integrating with frameworks like LangChain and LlamaIndex. Self-hosting deploys via Docker Compose with Traefik for routing, requiring only a clone, environment configuration, and a single docker compose command. On RepoCloud, deploy Agenta on a dedicated VPS with root SSH access, persistent storage for evaluation datasets and traces, and complete control over model provider credentials, all under the MIT license with no usage restrictions.

Give every agent your team runs the same front door, and the model chaos behind it becomes manageable. Tingly Box is a self-hosted gateway with a web console where providers, keys, routing rules, and team usage live in one place. Claude Code, OpenCode, Codex, Xcode, and other clients simply call the endpoint. A request arrives. The gateway reads your rules, weighs cost against speed against the policy you wrote, picks a model and a token, translates the protocol if the two ends disagree, and streams the answer back. Existing subscription quotas are spendable here, connected by OAuth beside ordinary API keys, and per-scenario profiles let quick edits and deep refactors land on different models by default. Team mode shares that endpoint properly. Model rules are managed centrally, each member receives a dedicated key, data stays isolated per user, and the usage dashboard shows exactly who consumed what. The gateway also speaks images, generating and editing through the same address with a playground for testing prompts before clients depend on them. Agents remain reachable after you leave the desk, driven through Telegram, DingTalk, Feishu, Lark, Weixin, or WeCom, with guardrails and an MCP gateway available as power-ups. Virtual models give new rules a safe target for testing and benchmarking before real traffic moves over.
