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
Stars203K
Commit8h ago
LicenseUnknown
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.
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.
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
Stars154K
Commit10h ago
LicenseMIT
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

LicenseBSD-3-Clause
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.
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
Stars126.6K
Commit8h ago
LicenseMIT
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
Stars122.3K
Commit11h ago
LicenseAGPL-3.0
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
Stars113.1K
Commit8h ago
LicenseAGPL-3.0
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.
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
Stars108.7K
Commit8h ago
LicenseApache-2.0
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
Stars85.8K
Commit8h ago
LicenseMIT
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
Stars90.2K
Commit8h ago
LicenseApache-2.0
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.
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.
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

LicenseMIT
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
Stars72.1K
Commit3d ago
LicenseMPL-2.0
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.
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.
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
Stars52.3K
Commit1d ago
LicenseMIT
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.
Deploy applications to your own servers with one click

Coolify is a deployment platform that runs on servers you already pay for. It builds from a Git repository, provisions databases, issues certificates, and handles rollbacks, without the per-instance pricing of a hosted platform.
Lightweight password vault server for Bitwarden clients
Stars48.1K
Commit4d ago
LicenseAGPL-3.0
Vaultwarden reimplements the Bitwarden server API in Rust so that it runs comfortably on a Raspberry Pi or a small VPS, while the official Bitwarden desktop, mobile, and browser clients connect to it unchanged.
Speech recognition that runs anywhere, with no runtime

Commit21h ago
LicenseMPL-2.0
Penpot stores designs as SVG and uses CSS layout primitives - flex and grid - as its layout model, so what a designer builds maps onto what a developer implements rather than needing translation.
Issue tracking and planning without per-seat pricing
Stars40.1K
Commit20h ago
LicenseAGPL-3.0
Plane covers the ground between a lightweight tracker and a full project suite: issues, cycles, modules, and roadmaps, with views that suit both engineers and the people asking them for dates.
Multi-channel notification infrastructure for applications
Stars39.7K
Commit8h ago
LicenseUnknown
Novu takes the notification logic that usually ends up scattered across a codebase - which channel, which template, which quiet hours, which digest window - and puts it behind one API and one workflow editor.
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.
Schedule and analyse posts across 30+ social networks

Commit8h ago
LicenseAGPL-3.0
Postiz is a self-hostable scheduler for teams that publish to many networks and do not want to pay per seat for the privilege. It covers planning, drafting, approval, and publishing, with AI assistance for turning one post into per-network variants.
Outline is a documentation workspace built around search and structure rather than infinite nesting. Collections, a strong editor, and genuinely fast full text search make it usable at the size where most wikis become write-only.
Team messaging for organisations that cannot use hosted chat
Stars33.2K
Commit19h ago
LicenseAGPL-3.0
Mattermost is channel-based team chat designed for environments where the message history has to stay inside a boundary: defence, healthcare, and regulated finance are its natural constituency.
Commerce building blocks rather than a fixed storefront
Stars32.4K
Commit2d ago
LicenseMIT
Medusa is a set of commerce modules - cart, orders, pricing, inventory, fulfilment - exposed as APIs you compose, rather than a themed storefront you customise around the edges.
A content platform that wraps your existing SQL database
Stars30.8K
Commit1d ago
LicenseBSL-1.1
Directus points at a SQL database you already have and generates an admin interface and an API over it, without imposing its own schema. Existing tables keep their names, types, and constraints.
Ente stores photos and videos encrypted on the client, so the server holds ciphertext it cannot read. Sync, albums, and sharing all work on top of that constraint rather than around it.
File sync, sharing, and a suite of apps on your own server
Stars30.1K

LicenseAGPL-3.0
Nextcloud started as file sync and grew into a full collaboration suite: documents, calendar, contacts, chat, and an application ecosystem on top of the same account system.
Link management and attribution for modern marketing
Stars24.6K
Commit8h ago
LicenseAGPL-3.0
Dub is a link platform rather than a shortener. Every link carries analytics, UTM handling, device and geographic targeting, and conversion attribution back to the click that produced it.
Jitsi Meet gets to a working video call faster than anything else: open a URL, share it, done. No accounts, no downloads, no meeting identifiers to read out.
Customer conversations from every channel in one inbox

Chatwoot collects website chat, email, WhatsApp, Instagram, and SMS into a single agent inbox with shared assignment, canned replies, and a help centre.
Screen recorder with editing and instant shareable links
Stars21.4K
Commit16h ago
LicenseAGPL-3.0
Cap records screen and camera, then gives you an editor with backgrounds, automatic zooms, and cursor smoothing before you share a link. It is built in Rust on Tauri, so the binary is small and recording does not tax the machine it is recording.
Lightweight web analytics without cookies or personal data
Stars23.5K
Commit2d ago
LicenseAGPL-3.0
Plausible answers the handful of questions most sites actually ask - what pages get read, where readers came from, what converted - and deliberately declines to answer the rest. There are no cookies, no cross-site identifiers, and no consent banner needed.
Focalboard is a board and table tool that runs as a desktop application against local files, or as a server for a team. It covers the kanban, table, and calendar views most planning needs without a subscription or an account.
OpenSEO covers keyword research, backlink analysis, competitor monitoring, and rank tracking in one self-hosted application, using DataForSEO as the data source so you pay for the data rather than the seat.
Secret management for applications and infrastructure

LicenseMIT
Infisical stores application secrets, syncs them into the platforms that need them, and rotates the ones that support rotation. Environments and folders keep development and production credentials properly separated.
Listmonk is a single Go binary and a Postgres database that handles subscriber lists, segmentation, campaigns, and bounce processing at a scale that would be expensive on a hosted platform.
Parlant addresses the problem that stops most support agents from shipping: a model that is helpful ninety-five percent of the time is not safe to put in front of customers. It manages behaviour through explicit, context-matched guidelines rather than one long prompt.
Collaborative wiki with real-time editing and diagrams

Commit2d ago
LicenseAGPL-3.0
Docmost is a documentation workspace with real-time collaborative editing, nested spaces, and diagram support built in rather than embedded from elsewhere.

Formbricks covers both link surveys and in-product micro-surveys triggered by user behaviour, which is the combination most research tooling splits across two paid products.
Twenty rebuilds CRM around the interaction patterns people already know from modern productivity tools: keyboard navigation, inline editing, flexible record views, and a data model you can extend without a consultant.
Hanko is an authentication service built passkey-first rather than passkey-eventually. Passwords are optional from the start, and the hosted components handle the awkward parts of the WebAuthn ceremony that teams usually get wrong.
Conversational forms built on a visual flow canvas

LicenseAGPL-3.0
OpenPanel merges the two dashboards most teams keep open side by side: page-level web analytics and event-level product analytics. Funnels, retention curves, and session replay sit next to traffic sources rather than in a separate product.
No-code database and application builder you can host

Baserow is a spreadsheet-shaped database with the API and permission model of a real backend underneath. Non-technical colleagues get grid, gallery, kanban, and calendar views; engineers get a REST API and webhooks over the same data.
Localisation platform with in-context translation editing
Stars4,085
Commit13h ago
LicenseApache-2.0
Tolgee's distinguishing feature is that translators work in the running application. Alt-click a string in the app and the editor opens over it, with surrounding context visible, which removes most of the ambiguity that produces bad translations from a spreadsheet.
GlitchTip accepts events from the official Sentry SDKs, which means adopting it is a DSN change rather than an instrumentation project. Stack traces, breadcrumbs, releases, and issue grouping all work as expected.
Continuous compliance automation across many frameworks
