Open Source Developer Tools Apps

Open-source reactive database that lets developers build live-updating apps with pure TypeScript, strong consistency, and real-time subscriptions—no separate API layer required.

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

The complete DevOps platform that unifies Git hosting, CI/CD, issue tracking, and security scanning into a single self-hostable application.

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.

Open source observability platform that unifies logs, traces, metrics, and session replays on ClickHouse — now the core of ClickStack.

Compose, extend, and observe every backend service in real time using three primitives: Workers, Functions, and Triggers.

The programmable open source core ledger for fintech — build money-moving applications with atomic multi-posting transactions, account-based modeling, and Numscript, a built-in DSL for financial logic.

A free, local-first developer workspace unifying snippets, notes, HTTP requests, calculations, drawings, and dev tools in one desktop app.

Run LLM-generated Python code safely inside your agent—no containers, no CPython, no compromise—with sub-microsecond startup.

Embedded KV store built on object storage with zero replication cost

The open-source user infrastructure platform — authentication, teams, payments, emails, analytics, and more on a single unified user model.

A local desktop hub that unifies SSH, Docker, Kubernetes, VMs, and remote desktops into one interface — no agents, no remote setup.

A local desktop workspace that gives every coding task its own agent, Git branch, and worktree, then tracks tasks, pull requests, CI, and reviews for 27 coding agents on one live Kanban board.

A zero-configuration terminal text editor with familiar keybindings, full mouse support, LSP-powered IDE features, and a built-in orchestrator for running multiple coding agents in parallel worktrees.

Open-source metering and billing engine for AI, agentic, and DevTool monetization — ingest usage events in real time and turn them into accurate invoices automatically.
