Simulithic tests your product with simulated people: AI agents that map it, test every pull request, and keep watching production. These pages take you from the first snippet to a check on every pull request. Start with Getting started if you are new; every other page stands on its own.

Start

  • Getting startedWhat Simulithic does, and your first hour: capture your real visitors, map your product, run your first simulation, put a check on every pull request, and hear when production breaks.
  • Set up with your coding agentOne file your coding agent follows end to end: install, account, workspace, the product map, state-asserting journeys, a first run and the check on every pull request — with a verification after each step.
  • CaptureThe Behavior SDK: one tag that records how your real visitors use your product — behaviour, never content — so the simulated people run on their devices and take their routes.
  • The StudioWhere your workspace lives: what is tripping up your users right now, replays of real sessions, the friction that recurs, and your visitors grouped into personas.

Run

  • SimulateSend simulated people through your product from the Studio: the canvas of flows, who goes, how many, on what devices, and what a run gives you back.
  • CLIThe simulithic command: sign in, map your product, manage its flows, queue simulations against any URL or your local dev server, and run the pull-request check.
  • Pull-request checksThe same simulated people through the same flows on the PR’s build and on production, a verdict per flow and per device, and one comment on the pull request.
  • Monitors and alertsThe same simulated people through the same flow on a schedule, so you know the moment it stops working, and Slack for when it does.
  • ExperimentsPredict what a change does to a goal before you ship it, on people built from your real sessions, and check the prediction against what really happened.

Manage

  • Workspace and settingsProjects, keys, allowed origins, the team, privacy, a stored sign-in for simulations, integrations and billing: everything under Settings.
  • FAQThe questions we hear most.
