Star on GitHubDevTools Studio
Build API workflows from real traffic. Import a HAR, get a flow with tokens/IDs mapped automatically, export clean YAML, and hand it to CI with DevTools CLI.
- Import HAR → auto-generate flow tree
- Assertions + variable mapping (rule-based overrides)
- Export YAML for PR review
- Runs locally, no account required
DevTools Studio: Visual flow builder with automatic variable mapping and YAML export
How Studio Works
Import HAR files
Drag and drop HAR files from Chrome DevTools or any proxy. Studio parses requests, headers, and auth tokens automatically.
Auto-map variables
Studio detects tokens, IDs, and session data, then auto-generates variable mappings. Override with custom rules when needed.
Export clean YAML
Export flows as human-readable YAML files for Git review. Run them in CI with DevTools CLI for JUnit/JSON reports.
