Simulithic
Simulithic provides a command-line tool that automatically maps and tests every user flow in a web application with a single command, eliminating the need to write or describe tests. The tool verifies flows across real browsers, devices, screen sizes, and network speeds in isolated VMs, and integrates into local development, CI/CD pipelines, and production monitoring.

Problem
Writing comprehensive end-to-end tests requires significant time and foresight, and teams often miss critical user flows, leading to production breaks. Manually describing every flow is impractical, and maintaining test suites becomes a bottleneck in development.
Solution
Simulithic provides a command-line tool that automatically maps and tests every user flow in a web application with a single command. By running `simulithic map`, the tool explores the app and generates a complete map of all user flows without any test writing or flow description. It then verifies each flow across real browsers, devices, screen sizes, and network speeds—each in its own isolated VM. The tool integrates directly into local development workflows and CI/CD pipelines, running as an end-to-end step that comments on pull requests with any issues found, catching regressions before merging. It also supports production monitoring, running user flows on real devices as often as every 30 minutes and notifying teams via Slack when a flow breaks.
Target Audience
Primary users are software development teams, particularly frontend and full-stack engineers, who need automated end-to-end testing without the overhead of writing and maintaining test suites, as well as engineering organizations using CI/CD pipelines.
Features
- One-command flow mapping (`simulithic map`) that automatically explores an app and maps every user flow without requiring test descriptions
- Cross-environment verification across Safari, Chrome, Firefox, macOS, Windows, iOS, Android, and network conditions from Fast Wi-Fi to 3G, each in an isolated VM
- Local development integration via terminal command (`simulithic qa`) or through AI coding agents like Claude Code or Codex before opening a pull request
- CI/CD pipeline integration that runs as the end-to-end step and comments directly on pull requests with any broken flows
- Production monitoring that runs user flows on real devices as often as every 30 minutes and alerts via Slack when a flow breaks
- Support for both local and production testing, with the ability to test real traffic against the product's own capture and simulation pipeline
