# Simulithic

> AI agents map every journey in your app, test them on every pull request, and watch production. Know what broke, on which device, before you merge.

Simulithic sends simulated users through your product before real ones get there. Each one drives your app in a real browser or on a real phone, on the devices your visitors use, carries your flows out end to end and reports what broke. Teams run them on every pull request, as a check that compares the PR's build with production; on a schedule against production, as monitors; and on demand from the Studio.

Accounts are invite-only while we onboard design partners. To get started, book a 20-minute call from the home page or write to team@simulithic.com.

## Docs

- [Docs](https://www.simulithic.com/docs): How to map your product, put an AI end-to-end check on every pull request, monitor production, and capture your real visitors.
- [Getting started](https://www.simulithic.com/docs/getting-started): What 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 agent](https://www.simulithic.com/docs/agent-setup): One 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.
- [Capture](https://www.simulithic.com/docs/capture): The 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 Studio](https://www.simulithic.com/docs/studio): Where 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.
- [Simulate](https://www.simulithic.com/docs/simulate): Send 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.
- [CLI](https://www.simulithic.com/docs/cli): The 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 checks](https://www.simulithic.com/docs/pull-request-checks): The 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.
- [GitHub App](https://www.simulithic.com/docs/github-app): Install the App once and every pull request gets a check and a comment, with no workflow file and no token in the repository.
- [Monitors and alerts](https://www.simulithic.com/docs/monitors-and-alerts): The same simulated people through the same flow on a schedule, so you know the moment it stops working, and Slack for when it does.
- [Experiments](https://www.simulithic.com/docs/experiments): Predict 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.
- [Workspace and settings](https://www.simulithic.com/docs/account): Projects, keys, allowed origins, privacy, a stored sign-in for simulations, integrations and GitHub under the project’s Settings; the team, billing and your account under Workspace.
- [FAQ](https://www.simulithic.com/docs/faq): The questions we hear most.

## Blog

- [What is verification engineering?](https://www.simulithic.com/verification-engineering): Verification engineering is the practice of proving software works on every change, before and after it ships. Why it matters with AI coding agents, and how it’s done.

## Plans

- [Plans](https://www.simulithic.com/pricing): Every plan includes PR checks and production monitoring, sized by how many journeys you test and where they run. Prices are quoted on a 20-minute call.

## Optional

- [Blog](https://www.simulithic.com/blog): Notes from the Simulithic team on verification engineering and testing the software coding agents write.
- [Privacy Policy](https://www.simulithic.com/privacy): How Simulithic collects, uses, and protects information on simulithic.com and in the Simulithic product.
