Define endpoints, configure auth, set headers. Organize requests into workspaces, projects, and categories.

Composable Templates

Create reusable field templates. Reference other customs to build complex nested data structures.

Instant Preview

CLI Integration

Sync workspaces to your machine. Generate data from the command line. Perfect for CI/CD and scripts.

Local Storage

All data stays in your browser. No account required. Export/import for backup and sharing.

Sync your workspace once, generate data anywhere
