Simulithic

Simulithic is an AI end to end testing service that maps user flows in a web or mobile app and tests them on every pull request. AI agents explore the app on their own, so teams do not write tests or describe flows by hand. A single command, simulithic map, discovers the flows, and simulithic qa runs them. It is built for product and engineering teams shipping frequently. Flows are checked against combinations of Safari, Chrome and Firefox, on macOS, Windows, iOS and Android, across different network speeds, each in an isolated virtual machine. The tool runs in a terminal, can be triggered by coding agents such as Claude Code or Codex before a pull request is opened, runs as a step in CI pipelines and comments on the pull request with anything that broke. It also monitors production, running flows as often as every 30 minutes and alerting through Slack when one fails. There are three plans, Starter, Team and Enterprise, differing in pull request checks, number of monitored journeys, monthly sessions, platforms and how long replays are kept. Starter covers web only with 2,000 sessions a month, Team adds phones with 8,000 sessions, and Enterprise offers 25,000 sessions with SSO. Prices are not published, and the vendor quotes them on a call.
