Core Capabilities
Chained Request Pipeline
Run multi-step HTTP requests in exact sequence with drag-and-drop reordering, step skipping, and live latency metrics.
Dynamic Variable Extraction
Extract values like data.token via JSONPath and automatically inject them as {{token}} into downstream requests.
Automatic Cookie Jar
Captures session cookies from Set-Cookie headers and automatically forwards them across consecutive steps.
Private & Local Storage
No accounts, no external cloud syncing, and zero telemetry tracking. All workflow definitions and run history remain stored in your browser.
