AX Check

AX Check tests a product against the user that increasingly matters and that nobody tests for: a coding agent trying to get started with it. It takes a public domain, grades what the company calls the agent-experience fundamentals — whether the documentation, the entry points and the machine-readable surface of a site let an agent find what it needs — and then records real coding-agent sessions attempting to get started, publishing the attempt as a report rather than a score alone. The recorded session is the useful part: a failing grade tells a team that agents struggle, a recording tells them the exact step where the agent gave up. Starting a check or reading a report needs no account, no key and no captcha, which is a deliberate design choice for a tool whose subject is machine access. No pricing is published on the site at the time of this listing, so none is recorded here. It was announced on Hacker News on 18 September 2026.
