Meet ccat

One CLI for the whole loop: set up, write variants, read results, promote. Every command prints JSON when your agent asks for it.

CLI reference

Decided on the server

The routing file runs in Vercel Routing Middleware, before the page renders.

Docs

Under a millisecond

Weights are cached next to the proxy and refreshed every 30 seconds. Each decision hashes the visitor id against them; the x-ccat-decision-ms header shows the time.

No flicker, no script

The visitor gets the variant's HTML in the first response. Nothing swaps in the browser and nothing loads from a third party.

Onchain goals on Robinhood Chain

Count a token buy, a contract call or a holding as the conversion. Link the wallet on your server and the indexer credits the variant and the source that brought it.
