Open Source Developer Tools Apps

An open-source, horizontally scalable continuous profiling platform that pinpoints CPU, memory, and I/O bottlenecks down to the exact line of code, built by Grafana Labs alongside Loki, Tempo, and Mimir.

The open-source LLMOps platform unifying prompt engineering, evaluation, and observability for teams building reliable LLM applications.

The all-in-one AI platform for private document chat, no-code agents, and local LLMs with zero setup friction.

A command-line video and audio editor that automatically cuts silence, motionless footage, and other dead space using loudness, motion, and scene-detection analysis, then exports directly to Premiere, Final Cut Pro, DaVinci Resolve, and more.

Self-hosted cloud development environments and AI coding agents — defined in Terraform, connected via WireGuard, automatically shut down when idle.

The SQL database you can branch, merge, diff, and clone — Git for your data, MySQL-compatible and ready for multi-agent AI workflows.

A lightweight, offline-capable API development ecosystem for testing HTTP, GraphQL, WebSocket, MQTT, and SSE endpoints across web, desktop, and CLI.

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.

Develop applications directly inside your Kubernetes cluster with real-time file sync and instant hot-reload — no more docker build/redeploy cycles.

Open source, self-hostable webhook infrastructure that handles delivery, retries, HMAC signing, and multi-tenant event management so you never have to build a webhooks system from scratch.

In-context localization platform that lets developers and translators edit app strings directly in the running application, with AI-powered machine translation and framework SDKs for React, Angular, Vue, and Svelte.

An open-source developer platform for API infrastructure — issue and verify API keys, enforce global rate limits, route traffic through a gateway, and get per-key analytics and audit logs.

The open-source feature management platform that lets you ship code to production and control who sees it — without redeploying.

A fast, secure WebAssembly runtime that runs lightweight containers anywhere — from desktop and cloud to the edge and the browser.

Turn scripts into webhooks, workflows, and auto-generated UIs — the fastest self-hostable workflow engine, 13x faster than Airflow.
