AI code review, PR triage, and security monitoring for fast-moving teams
Every pull request gets line-level comments that draw on repository-wide context, coding guidelines and related files rather than just the diff in isolation.
Comments ship with one-click fixes, and CodeRabbit will iterate with human authors or coding agents until the feedback is resolved and re-verified.
Scores, ranks and routes incoming pull requests so high-impact changes are reviewed first and routine ones fast-track, with a board view of the queue.
Semantic diffs, blast-radius analysis and architecture diagrams make very large, agent-generated changes understandable in a few minutes.
Open-source, memory-efficient fine-tuning and local model running
Train and run nearly every major open model locally, with Day Zero support for new releases and a built-in hub that helps you pick the right quantization for your device.
Fine-tune with efficient methods and reinforcement learning while using noticeably less memory and completing runs faster than standard workflows.
Generate and edit images with models like Qwen-Image, FLUX and Z-Image, plus LoRA adapters, and create video with Wan and LTX.
Connect agents like Claude Code and Codex to your local models with a single command, or expose an OpenAI-compatible API for existing apps.
