The big idea
What is CatWrangler?
CatWrangler is an AI-mediated decision tracking and source-control system — version control rebuilt for teams of humans and AI agents who build the same codebase at the same time, resolving conflicts before they happen and keeping the reasoning behind every change attached to the code.
The old source control — Git, branches, locks, pull requests, merge conflicts — was written by humans, for humans, in the age of human teams. CatWrangler is that whole category rebuilt for the age of AI agents: written for agents, with humans steering.
Why an AI in the middle changes everything
Because an AI sits in the middle of every read, write, and merge, the system can do things Git never could: resolve a merge by reading the code, catch a conflict before it’s written, keep the reasoning behind every change attached to the change, and let you ask your codebase questions in plain English. And because all of it happens server-side, you never see version control at all.
Three truths fall out of that reframe
- Many agents, one codebase. Humans and agents build the same code at the same time, with no pre-planning — overlap is sorted out for you.
- Keep the why. Decisions are the artifact: captured with their reasoning and read by agents before they touch the code.
- Talk to your code. A conversational, zoomable layer lets anyone — even a non-coder — ask, understand, and steer the whole project in plain language.
“Most of the apparent speed is leverage, not me — the workflow I’m handed the moment I start, the decisions I can read, and the memory I can query.”
Related questions
Does CatWrangler use Git?
No. CatWrangler runs real version control underneath using Apache Subversion (SVN), but you and your agents never see Git, a branch, or a merge — you point your agents at it and build. Know that version control is handled for you automatically.
Is CatWrangler hosted?
Yes. CatWrangler is a hosted service with one isolated server per customer. There’s nothing to install or self-host.
What languages does it support?
Conceptually — any. The coordination and ship-it loop works the same for Node, Python, Go, mobile, games, even specs-only repos. Right now we only support a handful, though, because of the build and test environments that make agent development optimal. But at its heart, CatWrangler is a language-based system that connects decisions to code and manages multi-agent concurrency — which is actually pretty language-independent.
