Describe the test once. Run it in any framework.
Synthesize turns plain-English intent into working tests — Robot Framework, Playwright, Cypress, Selenium, Cucumber, or pytest-agents — and heals them when your UI changes.

Satellite Workers: Execute Tests Behind Your Firewall
Like GitHub self-hosted runners, but for test execution. Deploy a lightweight agent on your infrastructure. Tests run where your apps live — no VPN tunnels, no exposed ports, no data leaving your network.
- One-command install: pip install synthesize-satellite
- Secure pairing with single-use tokens
- Results stream back to Studio in real-time
- Heartbeat monitoring with auto-reconnect
Proven: 26 browser tests executed on a Mac mini satellite, results in Studio in 21 seconds.
How It Works
From plain English to production-grade tests in four steps.
Write Intent
Describe your tests in plain English using simple YAML. No boilerplate. No framework syntax. Just English.
suite: User Login
tests:
- User can login with valid credentials
- Bad password shows error
- Account locks after 5 failuresChoose Framework
Select from 6 built-in frameworks or create your own plugin. Same intent, different outputs, zero rewrites.
Execute & Heal
Tests run automatically. Failures trigger self-healing with new locator strategies, AI-suggested fixes, and confidence scoring.
- New locator strategies
- AI-suggested fixes
- Confidence scoring
- Automatic retry
Analyze & Improve
Historical analytics show which tests are flaky, what's getting slower, where regressions occur, and cost breakdowns.
- Flaky test detection
- Performance trends
- Regression tracking
- Cost per test
