Writing every test takes time.
Describing every flow takes foresight.
Prod breaks on the one you missed.

Nothing to describe and no tests to write. One run of simulithic map explores your app and maps every user flow on its own.

$simulithic map https://acme.dev

Every user flow is verified against the same browsers, devices, screen sizes and network speeds your users have, each in its own isolated VM.

While you codeRun simulithic qa in your terminal, or let Claude Code or Codex run it before opening a pull request.

In productionYour user flows run on the devices your visitors use, as often as every 30 minutes. If one breaks, you hear about it in Slack.
