Paste one SQL query result into a browser and get an interactive entity-relationship diagram instantly, with no installations, no credentials, and no account required. ChartDB's "Smart Query" runs a single statement in your existing database client that exports table definitions, relationships, indexes, and column types as JSON metadata, meaning the application never touches your database passwords. The canvas renders draggable entities with cardinality markers, collapsible grouping areas, and sticky notes for documentation. AI-powered DDL export generates migration scripts between dialect pairs like PostgreSQL to MySQL or SQLite to CockroachDB, analyzing your schema to produce target-specific DDL with correct type mappings and constraint translations. Import paths cover Smart Query JSON, raw DDL scripts, and DBML files from tools like dbdiagram.io. The AI layer connects to OpenAI or any compatible inference server including local vLLM instances running models like Qwen2.5-32B. Database coverage includes PostgreSQL (with Supabase and Timescale extensions), MySQL, SQL Server, MariaDB, SQLite (with Cloudflare D1), CockroachDB, ClickHouse, and Oracle. Exports to SVG with inline styles or SQL DDL in any target dialect. Ships as a React/Vite frontend behind Nginx in Docker, deployable on RepoCloud with dedicated VPS resources under the AGPL-3.0 license.

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.

Documents, tables, files, chat, and video meetings share one workspace in atomic.place, and AtomicServer is the part you host yourself so a team can edit together while the data stays on a machine it controls. Documents are collaborative rich text with comments, icons, and cover images, tables enforce a strict schema with keyboard navigation and copy and paste, and any table can switch to a kanban, calendar, dashboard, or timer view. Templates start an issue tracker, a CRM, a project task list, or a time tracker. Live cursors, typing indicators, and presence avatars show who is working where, group channels carry attachments, replies, and search, and an infinite canvas can be drawn on together. Every write is a signed commit, so a full history is kept. Read and write rights follow the resource hierarchy, and invite links bring people in. Websites are designed in the browser, published in one click, and rolled back to any earlier version. Custom classes and properties come from the Ontology Editor, small apps are plain JavaScript screens over the same data, and AI features work with any model through OpenRouter or a local Ollama and support MCP. Typeahead search suggests results as you type. A REST API answers in JSON-AD, Turtle, or JSON-LD for automation, and export and import commands write and read JSON-AD backups.

Picture your object storage scattered across a home server, a friend's rack, and a cheap VPS in another country, still answering S3 requests like nothing happened: that is exactly the deployment Garage was built for. Every object is replicated to three zones, so losing a node, a disk, or an entire site degrades the cluster instead of destroying your data. Applications talk to it with the standard S3 API: create buckets, upload objects in multiple parts, list and copy them, and hand out access keys that are scoped per bucket. A separate web endpoint serves static websites straight from buckets with CORS support, which covers personal sites, documentation, and release downloads without another server in the chain. The whole system ships as one dependency-free binary that asks for about a gigabyte of RAM and any x86-64 or ARM CPU from the last decade, second-hand hardware very much included. There is deliberately no consensus protocol to babysit: nodes gossip their cluster layout, tolerate 200-millisecond links, and keep serving reads while parts of the fleet are unreachable. Deuxfleurs runs it in production for their own hosting, and common pairings include restic or rclone backup targets, Matrix media storage, and Nix binary caches.

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.

Zapier's job, on your own server: Activepieces is an open-source workflow automation platform built to be exactly that replacement. Flows are built in a visual no-code editor with triggers, actions, loops, conditional branches, auto-retries, raw HTTP steps, and code steps that run JavaScript or TypeScript with full npm package support. Integrations are "pieces" - type-safe TypeScript npm packages with hot reloading for local development - and the catalog spans 600+ services, with the large majority contributed by the community. The platform is AI-first in two directions: native AI pieces call OpenAI, Anthropic, Google, and Azure models inside flows, and every piece automatically doubles as an MCP server, so assistants like Claude Desktop and Cursor can invoke your integrations and workflows through natural language. A built-in MCP server also exposes 30 tools for building flows, managing tables, and running tests agentically. Flows are fully versioned with draft and locked states. The core is MIT-licensed and runs on TypeScript with PostgreSQL and Redis.

Powering mission-critical infrastructure at OpenAI, Cursor, Replit, Lovable, Retool, and Snap with over 22,000 GitHub stars, Temporal is the durable execution platform that originated from Uber's Cadence project — built by the creators of AWS SQS, AWS SWF, and Azure Durable Functions with nine years of production-proven reliability. The workflow-as-code model lets developers write business logic in Go, Java, Python, TypeScript, .NET, PHP, or Ruby using native SDKs, while the Temporal Server automatically persists state at every step, replays from failures, retries activities with configurable backoff policies, and manages task queues without developers writing reconciliation logic. Workflows support signals for external event injection, timers for scheduled delays, child workflows for decomposition, and queries for real-time state inspection — all backed by deterministic replay over an event-sourced history that guarantees exactly-once semantics. The Web UI provides visual workflow execution inspection with event timelines, pending activity monitoring, namespace management, and worker health dashboards. Persistence supports PostgreSQL, MySQL, or Apache Cassandra for horizontal scalability, with Elasticsearch or OpenSearch for advanced workflow visibility queries. Multi-cluster replication enables global failover across data centers. The self-hosted stack deploys via Docker Compose with the auto-setup image, PostgreSQL, Web UI, and admin tools — operational within 30 minutes.

More than 70 automated checks sniff out broken links, redirect chains, and missing meta tags across your whole site, and SEOnaut, the self-hosted SEO audit crawler, sorts every finding into critical, alert, or warning so you know what to fix first. Add a website as a project, press Crawl Now, and watch URLs stream in with their status codes; a Stop button ends any run that wanders off. Reports also cover duplicate titles and descriptions, heading order, hreflang, canonicals, image alt text, thin content, orphan pages, and non-HTTPS URLs, while a passed-checks list shows what is already healthy. Dashboard charts follow crawl history, issue trends, status codes, link types, and page depth. Crawl options are set per project: ignore robots.txt, follow nofollow links, include noindex pages, read the sitemap, allow subdomains, check external links, or authenticate with HTTP Basic to audit a password-protected staging site. Page Details opens any URL with its inlinks, outgoing links, redirections, and images, and URL Explorer searches the crawled pages by term. Export sitemap.xml, CSV lists, or a replayable WACZ archive. Each person picks a light or dark theme and one of five interface languages.

Commercial flight logbooks frequently lock historical travel records behind annual subscriptions or shut down unexpectedly, whereas AirTrail preserves your complete aviation history on an interactive world map under your own control. Enter a flight number to look up routes automatically or log departures manually with seat numbers, cabin classes, aircraft registrations, timestamps, notes, and custom metadata fields. Switching from another tracker takes seconds: the built-in importer ingests CSV, ICS, and JSON exports from MyFlightradar24, Flighty, App in the Air, OpenFlights, TripIt, JetLog, byAir, and JetLovers. The vector map renders geodesic flight paths, recorded GPS tracks, and airport runway details across customizable basemaps. Detailed statistics dashboards break down total distance flown, time in the air, top airlines, aircraft models, and visited countries. Families and travel groups can share a single instance with role-based permissions, OAuth single sign-on, and read-only public links, while developers automate entries through the versioned REST API or Model Context Protocol server.

Lunarr turns the movie and TV folders you already store into a private streaming service with posters, progress tracking, and play-anywhere convenience. Point it at local disks or at libraries living on SFTP and WebDAV servers, and it scans, identifies, and decorates everything with TMDb artwork, cast pages, similar titles, and because-you-watched recommendations. Press play and the file either streams directly or is transcoded on the fly into seekable HLS, generating only the segments around the moment you are watching instead of converting whole films up front. Continue watching follows you between sessions, sidecar subtitles are picked up automatically, and known intros and credits can be skipped. Send the picture to the big screen with Chromecast or AirPlay, pair new devices without typing passwords, and hand a guest a share link instead of your account. Underneath, an admin console manages users, roles, and which libraries each person may see, watches background jobs, and holds API keys and registration settings. Rescans run on schedules you set from minutes to a month, local folders can be watched live for new arrivals, and metadata refreshes itself on a timer.

Stitching together separate SaaS subscriptions for applicant tracking, time-off requests, expense approvals, and monthly payroll creates fragmented employee records and costly per-seat bills; Frappe HR consolidates over 13 human resource modules into one self-hosted platform. People operations teams manage the complete employee lifecycle from job openings, interview assessments, and offer letters through structured onboarding, internal transfers, promotions, and exit interviews. Shift planners organize rotational rosters and capture geolocation-verified attendance check-ins, while employees request leave against regional holiday calendars and multi-tier policies. Finance and payroll managers build custom salary structures, configure regional income tax slabs, process regular or off-cycle payslips, and reconcile employee expense claims and cash advances directly with ERPNext accounting ledgers. Goal tracking and appraisal cycles align individual key result areas (KRAs) with self-evaluations and manager feedback scores. A progressive web app interface lets staff submit leave requests, log attendance, and file expense receipts from their phones.

Convoy is an enterprise-grade webhooks gateway that manages both incoming and outgoing webhook traffic to guarantee reliable event delivery without exposing internal microservices to the public internet. Organizations deploy the platform at the edge to ingest events from message brokers such as Apache Kafka, RabbitMQ, and Google Cloud PubSub, or receive HTTP webhooks from third-party services directly. The gateway enforces delivery policies through configurable rate limiting per endpoint, circuit breaking during downstream outages, and automated retries using constant or exponential backoff with jitter. Developers can generate customer-facing webhook portals embedded via iframes, allowing end users to inspect delivery attempts, verify HMAC-SHA256 signatures, and manually replay failed events. Comprehensive security controls include static egress IP proxying to prevent server-side request forgery, automated rolling secret keys, and instant alerting via Slack or email when endpoints fail consecutively.

Your bank balance is only part of what you own, and MoneyMatter adds the rest: cash accounts, brokerage portfolios, cars, loans, and private deals roll into one net worth figure in your base currency. Add transactions by hand, import CSV, OFX, QFX, YNAB, Wallet, or Microsoft Money files, or let an AI model you provide parse a statement, while Monobank, SimpleFIN, Lunch Flow, and Walutomat connections sync accounts automatically. Each transaction can carry categories, tags, payees, notes, attachments, and splits, transfers and refunds link to their counterparts, and automation rules tidy new entries. Envelope-style budgets assign money to lines with Assigned, Activity, and Available columns and rollover rules, savings goals read progress from account balances, subscriptions and bills send reminders, and loans show payoff projections. Stocks, ETFs, and crypto are priced daily, vehicles depreciate along a curve, and a FIRE planner estimates years to Lean, Regular, Fat, Barista, and Coast FIRE. A customizable dashboard, cash flow, money flow, net worth history, trends comparison, and pivot table chart the results. Share accounts with a household member, export JSON, CSV, or XLSX, back up everything, or connect Claude, ChatGPT, or Claude Code through the built-in MCP server.

"As simple as Trello but as feature-rich as Jira" is how the Leantime team frames its goals-focused project management system for non-project managers - built from the ground up with ADHD, autism, and dyslexia in mind, with behavioral science shaping customizable dashboards, time blocking, low-cognitive-load prioritization, and Kanban, list, table, Gantt, and calendar views so each person works the way their brain does. The PHP application (AGPL, Laravel Blade frontend) connects strategy to execution: tasks with unlimited subtasks and dependencies roll up into milestones on a timeline, sprints and retrospectives handle iteration, and strategy-level blueprint boards - Lean Canvas, SWOT, risk analysis, goal and metric tracking - keep the "why" attached to the work. Knowledge lives alongside: wikis and docs, idea boards, comments on everything, file storage on S3 or local disk, even screen and webcam recording. Time tracking with timesheets supports estimation and client billing. Admin features are serious for an OSS tool: per-project permissions, two-factor auth, LDAP and OIDC single sign-on, Slack, Mattermost, and Discord integrations, a plugin system, and an expanding API that now powers a mobile app. Recent releases added multi-collaborator task assignment and low-vision accessibility improvements. Available in 20+ languages.

High-resolution weather forecasts became a free commodity because of Open-Meteo - and this deployment puts the whole open-source engine on your own infrastructure. The public open-meteo.com service aggregates national weather models (NOAA GFS, DWD ICON, ECMWF, Meteo-France, and others) into one consistent JSON interface; self-hosting gives you that same API without rate limits, third-party dependency, or usage metering. The architecture is two cooperating services: the API server exposes forecast endpoints fully compatible with Open-Meteo query parameters - latitude, longitude, hourly and daily variables like temperature, precipitation, wind, and radiation - while a background sync worker downloads fresh weather model data on a configurable interval into a shared persistent volume at /app/data, so forecasts stay current and survive restarts without re-downloading. You control which weather models to mirror, which variables to store, how much historical depth to keep, and how often to refresh - meaning a lean deployment can sync only the model and region you actually query. Responses are plain HTTP/JSON, so integration with dashboards, Home Assistant-style automations, agricultural monitoring, IoT fleets, or any application takes minutes. For anyone making thousands of forecast calls a day, replacing a metered weather API with your own instance turns a recurring bill into a flat infrastructure cost.

Exploratory data work, teaching material, and research code all live in the same browser tab with JupyterLab, the web workspace of Project Jupyter. Notebooks combine runnable code cells, Markdown, and rich output such as images, JSON, and Vega charts, and they use the same notebook format as the classic Jupyter Notebook. Any Jupyter kernel can execute the code, so Python, R, and other languages share one interface, and code inside plain text files such as Markdown or LaTeX can be run interactively as well. Tabs and splitters arrange documents side by side, and a notebook's cell outputs can be mirrored into their own tab to build a simple dashboard with interactive controls. Code consoles serve as scratchpads linked to a notebook kernel, while full terminals run system shells such as bash on the server. A visual debugger offers breakpoints, a call stack, and a variable explorer for kernels that support the Jupyter debug protocol. Markdown, CSV, and Vega documents show a live preview as they are edited, and built-in viewers handle images, JSON, and PDF files. The Extension Manager installs themes, editors, and renderers from PyPI, and real-time collaboration becomes available by adding the jupyter-collaboration extension. Access is protected by a generated token unless a password is set. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

The de facto dashboard of observability: Grafana is the open-source frontend that turns the data stores you already run into interactive graphs. It does not store metrics itself; it connects to the data stores you already run and turns their contents into interactive dashboards. Supported sources number over 150 via plugins: Prometheus, Loki, Tempo, InfluxDB, Elasticsearch, MySQL, PostgreSQL, Microsoft SQL Server, AWS CloudWatch, Azure Monitor, Google Cloud Monitoring, and many more. Dashboards are built from a large library of panel types (time series, heatmaps, tables, gauges, logs) with template variables for reusable, parameterized views. Unified alerting evaluates rules against any connected data source, not just Prometheus, and routes notifications to Slack, PagerDuty, email, and other channels with grouping and silencing - unlike Prometheus Alertmanager, a single rule can combine a Loki log pattern, a PostgreSQL query result, and a CloudWatch metric. Dashboards serialize to JSON and data sources configure via provisioning files, so the entire observability setup can live in Git and deploy repeatably across environments. Explore mode adds ad-hoc querying outside dashboards, with split view for correlating a metric spike against the matching log lines, and access control spans organizations, teams, folder permissions, and OAuth, LDAP, and SAML integration. Written in Go and TypeScript, AGPL-licensed. Self-hosting gives you unlimited users, dashboards, and queries at flat hosting cost, without Grafana Cloud's usage-based pricing.
