Build with AI agents. Don't babysit them.
Felix is a delivery harness for AI coding agents — it enforces plans, validates output, and commits tested code so you wake up to completed features, not chat logs.
Works with...
Built for Team-Scale Delivery
Plans you can share without sharing code, enforced execution with validation, and artifacts that keep teams aligned.
terminal
Local Execution
Run inside your environment with durable state and zero external code exposure.
cloud_sync
Orchestration Layer
Coordinate teams while sharing plans and status, not repositories.
web_asset
Audit & Visibility
Plans, patches, and validation reports you can inspect and share.
architecture
Plan-Driven Specs
Requirements become executable plans before any code changes begin.
Frequently asked questions
- What is Felix?
- Felix is a delivery harness for AI coding agents. It turns a spec into an explicit plan, has an agent implement that plan, runs your tests and builds as validation gates, and commits only code that passes.
- Which AI coding agents does Felix work with?
- Felix is agent-agnostic. You choose the agent profile and model, such as Claude, ChatGPT, Gemini, Grok, Factory, or a local model, and the plan stays the contract regardless of which agent writes the code.
- What happens when tests fail?
- Backpressure is non-negotiable in Felix: a failing test, build or lint check halts progress on that task. If failures exceed the configured retry limit, the requirement is marked blocked so you can see exactly why it could not be completed.
- Does Felix run locally or in the cloud?
- The Felix CLI runs locally on your machine and keeps specs, plans and status as plain files in your repository. Optional sync mirrors artifacts to a Felix server so you can monitor and orchestrate agents on multiple machines from one dashboard.
- Which operating systems does the Felix CLI support?
- The Felix CLI is available for Windows (installer or portable zip), macOS (Apple Silicon and Intel) and Linux x64.
- Is Felix free?
- The Felix CLI is free for local execution. The Free Cloud Tier (Beta) adds Bridge orchestration for up to 5 team members and 10 active projects, with unlimited concurrent agents and 30-day artifact retention.
