Search once across OSI-approved open source, source-available and license-unknown projects, and proprietary products. Public source code is shown separately from an approved open-source license.
Search every product, then filter structural Projects separately from their license policy. Every view has its own address, so a filtered list can be shared or bookmarked.
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.
Speech recognition that runs anywhere, with no runtime
whisper.cpp is a C and C++ port of the Whisper speech recognition model with no Python dependency, quantised weights, and hardware acceleration across Apple Silicon, CUDA, and plain CPU.
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.
Multi-channel notification infrastructure for applications
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.
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.
File sync, sharing, and a suite of apps on your own server
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
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.
Video meetings with no account and no install
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
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
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.
Project boards that work offline and stay local
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.
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.
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.
A control layer for customer-facing AI agents
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.
