The median turn latency is 137.1 seconds per prompt, not per whole build, which derives to 20.6 min across the full nine prompt specification. That is a tenth percentile of 72.2 seconds and a ninetieth percentile of 249.0 seconds across 45 recorded executions.

How reliable is CatDoes?

48.9% of recorded executions met the published pass criterion with no operator intervention. 10 were partial and 13 failed outright. Every one of those rows is published on this page.

Can I export the code from CatDoes?

Yes, native project. The code ownership subscore is 66.0 out of 100.

Full-stack app builders / rank 20 of 20 / cycle 04

CatDoes benchmark

Aimed at mobile applications rather than web, which is why it posts one of the smallest no JavaScript payloads in the index and the weakest SEO subscore: there is barely a crawlable surface to measure. Judged on the parts of the spec it can reach it holds up, and the generated interface is genuinely good. The webhook and background job prompts were outside what the platform exposes.

Seeded at launch

The reader scores, lab notes and open ratings published here were written by this lab in August 2026 to populate the reader column before the site had readers. They are not customer submissions, they are not vendor supplied and nobody was paid for them. Anything submitted since then comes from a registered account. The lab index is measured from logged runs and is unaffected either way.

The reader index is a weighted mean of reader submitted axis scores using the published index weights, renormalised over the axes readers have scored. It is never blended into the lab index. How this works.

What agent performance looked like in practice

Across 45 recorded executions this product met the published pass criterion cleanly 22 times, partially 10 times and failed 13 times. The rows above carry the reviewer note for every non clean outcome, which is the only way to tell a product that fails loudly from one that fails quietly.
