Premium API Tool

The "API-First" Design & Test Engine

Flipping the script for API Developers and QA Architects. Make schemas the first-class object and eliminate the "guess-and-check" testing loop.

Schema-Sync Workspace

Stop wasting time toggling between Swagger docs and your API client. Build valid data according to your contract instantly.

Drag-and-drop interface for building complex nested JSON structures with real-time validation against your schema.

Instant bootstrap from Swagger, GraphQL, or Postman collections. Your existing documentation becomes alive in seconds.

Built-in proxy to bypass browser restrictions for local and staging environments. No plugins required.

Hotkey support, export to `curl`, and LLM-powered body pre-filling to accelerate your development loop.

A streamlined workflow from definition to deployment.

Pull in an existing Swagger or Postman file. Blockforger automatically deconstructs the endpoints or requests into editable schema blocks.

Drag schema blocks into the workspace. The visual editor highlights errors immediately if the JSON deviates from the schema.

Use the built-in CORS proxy to hit your local dev server or private staging environment without security headaches.

Inject dynamic tokens, emails, or custom variables into the request body using our simplified scripting layer.

Generate a shareable link that pre-fills the blocks for team review or collaborative bug reporting.

Reduce API integration time by eliminating "Malformed JSON" errors and providing a visual map of the data contract.
