How It Works

From plain English to production-grade tests in four steps.

1

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 failures
2

Choose Framework

Select from 6 built-in frameworks or create your own plugin. Same intent, different outputs, zero rewrites.

3

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
4

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

Everything You Need to Test Smarter

From natural language to production-ready tests in seconds. Built for teams that ship fast.

AI-Powered Generation

Write what you want tested in plain English. Get working tests in Robot Framework, Playwright, Cypress, Selenium, Cucumber, or pytest-agents.

Self-Healing Tests

Tests fix themselves when the UI changes. No more wasted time updating broken selectors. 90% of locator failures auto-resolved.

Smart Analytics

Know which tests are flaky before they break your pipeline. Historical trends, ML-powered predictions, and actionable insights.

Compliance Ready

SOC2, HIPAA, SOX traceability built-in. Generate audit reports automatically. Map requirements to test coverage.

Cost Optimized

70% reduction in LLM API costs through intelligent caching, local models, and smart routing. Pro tier pays for itself.

Team Collaboration

Shared knowledge base, code reviews, and quality gates. Scale test creation across your entire team.

Secrets Vault

Store API keys and credentials encrypted at rest. Injected securely at runtime — secrets never leave your vault unencrypted.

Satellite Workers

Execute tests behind your firewall. Deploy lightweight agents on your own infrastructure — like GitHub self-hosted runners for testing.

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.

Why Synthesize

Stop fighting your testing tools. Start shipping with confidence.

Write Once, Run Anywhere

Before

Rewrite tests for every framework. Robot Framework syntax today, Playwright tomorrow, Cypress next quarter.

After

Write in plain English once. Generate for Robot Framework, Playwright, Cypress, Selenium, Cucumber, or pytest-agents.

Tests That Fix Themselves

Before

Broken selectors after every UI change. Hours spent updating locators. Flaky tests blocking deployments.

After

Self-healing resolves 90% of locator failures automatically. AI-suggested fixes with confidence scoring.

One Platform, Full Visibility

Before

Scattered tools for writing, running, and analyzing tests. No unified view of quality or cost.

After

Generate, execute, heal, and analyze in one studio. Track costs, detect flaky tests, and ship with confidence.
