Tech stack
32 projects use PostgreSQL.
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.
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.
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
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.
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.
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.
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
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.
Design and prototyping built on open web standards
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
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.
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.
Schedule and analyse posts across 30+ social networks
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.
Team knowledge base that stays fast as it grows
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
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
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
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.
End-to-end encrypted photo storage across devices
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.
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.
Lightweight web analytics without cookies or personal data
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.
Secret management for applications and infrastructure
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.
Self-hosted newsletter and mailing list manager
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.
Self-hosted keyword, backlink, and rank tracking
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.
Collaborative wiki with real-time editing and diagrams
Docmost is a documentation workspace with real-time collaborative editing, nested spaces, and diagram support built in rather than embedded from elsewhere.
Document signing you can host and audit yourself
Documenso handles electronic signature collection with the signing certificate, audit trail, and field placement you expect, while keeping the documents on infrastructure you control.
Surveys and in-product research on your own infrastructure
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.
Conversational forms built on a visual flow canvas
Typebot builds forms that behave like a conversation: one question at a time, branching on answers, with the flow assembled visually rather than written in code.
A modern CRM that does not fight the way you work
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.
Passkeys, SSO, and MFA without vendor lock-in
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.
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
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.
Error tracking that speaks the Sentry protocol
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
Openlane automates the evidence collection and control tracking behind SOC 2, ISO 27001, GDPR, and a dozen other frameworks, mapping shared controls once rather than per framework.
