Tech stack
179 projects use Docker.
Visual workflow automation with room to drop into code
n8n sits between a no-code automation builder and a scripting environment. Workflows are assembled on a canvas from several hundred integrations, and any node in that canvas can be replaced with a JavaScript or Python function when the visual version stops being expressive enough.
Turn any website into clean, model-ready data
Firecrawl handles the unglamorous part of feeding the web to a language model: rendering JavaScript, following pagination, stripping navigation and cookie banners, and returning markdown or structured JSON that a model can actually use.
Build and deploy AI agents and RAG pipelines visually
Dify is where a prompt experiment becomes something a team can operate. Workflows are assembled on a canvas, datasets are indexed and versioned, and every deployment gets an API endpoint with logging and cost tracking attached.
Drag-and-drop builder for agents and RAG pipelines
Langflow turns pipeline construction into a graph you can see. Components are Python underneath, so a flow that outgrows the canvas can be exported and run as code rather than rebuilt.
One chat interface for every model you run or connect
Open WebUI is the front end that turns a local inference server into something a household or a team can actually use. It handles accounts, conversation history, document retrieval, and model switching, and speaks to both local runtimes and hosted APIs.
Self-hosted photo and video backup for your own server
Immich replaces a cloud photo service with software that runs on hardware you own. Mobile apps for iOS and Android back up new photos and videos in the background, so the library on your server stays current without you thinking about it.
Postgres-powered backend platform for production apps

Open-source app people use to manage AI agents for work
Paperclip is an open-source app for managing teams of AI agents for work, with org charts, goals, budgets, and governance, self-hosted via local install, Docker, or a server.
Local-first smart home automation with no cloud dependency
Home Assistant runs on a box in your house and talks to devices directly rather than through their manufacturers' servers. That single design decision is why automations keep working when the internet is down, and why a discontinued cloud service does not brick your lights.
Autonomous agents that complete real engineering tasks
OpenHands runs agents that plan and execute multi-step engineering work: reading a repository, editing files, running tests, and iterating until a task is done. Each agent works inside a sandboxed runtime rather than on the host machine.
Open-source web crawler that turns pages into LLM-ready markdown
Crawl4AI is a Python crawler that turns websites into clean markdown and typed JSON for RAG pipelines, AI agents, and data pipelines.
Polished chat interface for many model providers

API client that runs in the browser and stays fast
Hoppscotch is an API client that opens in a tab. Requests, collections, environments, and history are all there, and it starts in the time a desktop client takes to check for updates.
Continuous file sync between your own devices only
Syncthing synchronises folders directly between devices with no server in the middle. There is no account, no storage quota, and no third party holding the data, because the data never leaves the set of machines you nominate.
Dashboards over whatever data you already store

Scheduling infrastructure you can host and extend
Cal.com covers the booking link case well, but its real distinction is that scheduling is exposed as infrastructure. Availability, event types, and bookings all have APIs, and the booking page can be embedded rather than linked.
