Open Source AI IDEs
AI-powered code editors like Cursor, Windsurf, and Kiro have changed how developers write software — but they come with vendor lock-in, usage limits, and closed-source models. This collection brings together the best open-source alternatives: full-featured AI IDEs you can inspect, modify, and self-host. Whether you want spec-driven development, multi-provider LLM support, or just a transparent AI coding environment, these projects give you the power without the paywall.
