Open-source coding agent runtime that runs in your IDE, your terminal or embedded via SDK, works with any model, and asks approval on every step.

One runtime, three surfaces: The same agent runs as a VS Code extension, a terminal CLI, or embedded in your own product through the SDK
Model agnostic: Works with Claude, GPT, Gemini, local Ollama or LM Studio models and any OpenAI-compatible endpoint, using your own key or weights
Plan then Act: Align on a strategy in Plan mode before execution, then approve each step in Act mode or flip on auto-approve
Multi-file edits with undo: Coordinated changes across a project with linter-aware fixes, diffs, checkpoints and one-click undo on every step
Live terminal execution: Runs bash commands and reacts to output as it appears, handling dev servers, test runs and deploys
Rules and Skills: Ship .clinerules with the repo so the agent follows your coding standards, architecture and deployment conventions
Multi-agent teams: Coordinator agents delegate to specialists with their own tools and context, and can run on cron for recurring automation
MCP and integrations: Register MCP servers and custom tools, chat from Slack, Discord, Telegram or Linear, and run headlessly in GitHub Actions or GitLab

A developer onboarding to an unfamiliar codebase and asking the agent how files, dependencies and behaviour fit together
Refactoring across a large repository while keeping imports, types and behaviour consistent
Running recurring maintenance — dependency bumps, lint sweeps, scheduled checks — from cron or a CI pipeline
A team that must keep code on self-hosted or local models for compliance reasons, pointing the agent at its own endpoint
Embedding an agent loop inside an internal developer platform via the SDK instead of building one from scratch
Encoding team conventions in .clinerules so every engineer's agent produces consistent, review-ready changes
Triggering a coding task from Slack or Linear and having the agent open the resulting change
