All Open Source Apps

Self-hosted WakaTime-compatible coding statistics backend that gives developers full control over their coding activity data.

An open source AI-native proxy that secures, observes, and governs agent-to-LLM, agent-to-tool, and agent-to-agent communication through MCP, A2A, and unified LLM routing.

Self-hosted web archiving that saves HTML, PDFs, screenshots, media, and code in open formats you own forever

Open-source, self-hostable authentication platform with passkeys, biometric login, SSO, MFA, and GraphQL admin API — a full Auth0/Clerk/Firebase alternative for SaaS and mobile apps.

eBPF-powered observability with AI root cause analysis — zero code changes required, full-stack visibility out of the box.

The batteries-included Python agent harness — planning, sub-agents, filesystem, shell, memory, and skills bundled in, built on LangGraph.

Open-source collaborative knowledge platform with real-time editing, AI writing tools, and full self-hosting control — built by the French and German governments.

A clean, Markdown-based publishing platform for writers, with built-in ActivityPub federation for connecting to the wider fediverse.

An incremental data indexing engine that keeps AI agent context perpetually fresh by reprocessing only what changed.

Your terminal coding companion — wire up any LLM with LSP intelligence, MCP extensibility, and a skills system that learns your workflow.

A temporal, verifiable graph database with git-like branching, integrated vector/text/geo search, and RDF/SPARQL/JSON-LD/openCypher support — benchmarked at 10.4x faster than the next database on the full Wikidata dump.

The painless self-hosted Git service that runs on anything from a Raspberry Pi to a $5 cloud droplet, delivering GitHub-like workflows as a single Go binary.
