A better developer experience
We’re building tools that make developing, debugging, and maintaining software more intuitive—so you can spend less time wrestling with your tools and more time making a difference.
Less friction in your daily work.
CATAgent work you can review
Codex UnleashedShape and get early access to Codex improvements
Our products
Keep your coding agent’s work focused and reviewable with CAT, or help shape practical Codex CLI improvements and get them sooner with Codex Unleashed.
Make your coding agent’s work easier to review.
CAT plugs into the Codex or Claude setup you already use. It breaks requests into focused tasks, makes their boundaries explicit, and checks the work before calling it done. You review the plan and approve the result.
Shape the Codex improvements that help you keep building.
Codex Unleashed focuses on small, high-leverage features and fixes that make AI-assisted development feel less fragile. Subscriber requests receive priority consideration, and completed, tested improvements are available early. It’s independent of OpenAI, with an early-access waitlist open now.
Open source libraries
Alongside our products, we maintain focused libraries that make application contracts clearer, more discoverable, and easier to debug.
How we build
A useful tool should be straightforward to learn and fit into the way you already work.
The right information, presented so you can understand the problem and decide what to do next.
Every avoided detour leaves more attention for the problem—and more time for life outside it.
More time to make progress
