Developer Tools is the broadest category on the site, spanning AI coding agents, API clients, headless backends, LLM infrastructure, and observability — over 30 tools in total.
If you're looking for AI-assisted coding, OpenCode, Zed, Void, and Kilo are the most active projects — see alternatives to Cursor and alternatives to GitHub Copilot for a fuller comparison. For API development and testing, Bruno and Hoppscotch cover most of what Postman offers. If you need a backend-as-a-service, Supabase is the most established option. For LLM tracing and observability specifically, check the Analytics & Data category instead.
FAQ
What's the best open-source AI coding assistant?
OpenCode is the most active provider-agnostic option; Void is the closest match if you want a Cursor-style VS Code fork. See alternatives to Cursor for a full breakdown.
What's the best open-source API client?
Bruno if Git-based collaboration on collections matters to you; Hoppscotch if you want a lighter, browser-based client. See alternatives to Postman for more detail.
Is there an open-source alternative to Firebase for backend infrastructure?
Yes — Supabase is the most widely adopted open-source backend-as-a-service, covering Postgres, auth, storage, and real-time subscriptions. See alternatives to Firebase.
Where do I find LLM observability and tracing tools?
Those live in the Analytics & Data category — see alternatives to LangSmith and alternatives to Datadog for the AI-specific options.
