AI coding agent for terminal, editor, and desktop
OpenCode is a coding agent that runs where you already work rather than in a separate chat window. The same session can be driven from a terminal, an editor extension, or a desktop client, and it keeps context across all three.
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.
Run open language models locally with one command
Ollama reduced local model hosting from an afternoon of CUDA troubleshooting to a single pull command. It handles model download, quantisation selection, GPU offloading, and memory management, and exposes an OpenAI-compatible endpoint on localhost.
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.
Collaborative whiteboard with a hand-drawn look
Excalidraw's sketchy rendering is not decoration. Diagrams that look provisional invite comment, where a crisp vector diagram signals a decision already made, so it is unusually good at the early part of a design conversation.
Inference engine that runs LLMs on almost any hardware
llama.cpp is the layer most local model tooling is built on. It is a C and C++ inference engine with no Python runtime, aggressive quantisation support, and hand-tuned kernels for a remarkably wide range of hardware.
Remote desktop you can point at your own relay server
RustDesk is remote desktop software where the relay server is a binary you can run yourself. That is the whole argument: the same convenience as the commercial tools, without your screen sessions transiting a vendor's infrastructure.
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.
Free 2D and 3D game engine with no royalties
Godot ships a complete engine, editor, and export pipeline under the MIT licence, which means no royalties, no revenue thresholds, and no licensing conversation before a project starts.
Let AI agents drive a real browser
Browser Use gives an agent a real browser rather than an HTTP client. It handles the translation between a model's intent and DOM actions, keeps a structured representation of the page in context, and recovers from the usual navigation failures.
Postgres-powered backend platform for production apps
Supabase gives an application everything it needs on the server side without hiding the database behind a proprietary abstraction. The primitive is plain Postgres, and the platform layers authentication, generated APIs, storage, realtime subscriptions, and edge functions on top of it.
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.
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.
Video editor that runs entirely in the browser
OpenCut is a timeline video editor that installs nothing and uploads nothing. Media stays in the browser, processing happens locally through WebCodecs, and there is no account step before you can cut a clip.
Polished chat interface for many model providers
LobeChat is the most designed of the open chat front ends. Plugins, an assistant marketplace, voice input and output, and vision support are all present, and the interface holds up next to commercial products.
Self-hosted uptime monitoring with a clean status page
Uptime Kuma monitors HTTP endpoints, TCP ports, containers, and certificates, and notifies through almost a hundred channels. Setup is a container and a few minutes.
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
Grafana is the visualisation layer that sits above other systems rather than a monitoring stack of its own. It queries Prometheus, Loki, PostgreSQL, ClickHouse, and dozens of other sources, and puts them on the same dashboard.
Documents, whiteboard, and database in one canvas
AFFiNE puts a document editor and an infinite canvas over the same content. A page can be read as a document or arranged spatially as a whiteboard, and edits in one mode are edits in the other.
Typo-tolerant search that is fast to run and fast to tune
Meilisearch is a search engine you can be productive with in an afternoon. Indexing is a POST, relevance is tuned through an ordered list of ranking rules, and results come back typo-tolerant by default.
