API Testing Simplified

• A declarative, JSON-driven API testing framework built on top of Playwright.

• Write tests as JSON, run them with playwright speed.

• Focus on what to test, not how. Write pure JSON suites that are easy to read, generate, and maintain.

• Runs on top of Playwright for industrial-grade reliability, visual tracing, and powerful reporting.

• Built-in Faker.js support allows you to generate random emails, names, and IDs for every request.

• Powerful interpolation engine with case, suite, environment, and global scopes for data reuse.

• Automated JSON Schema validation for both requests (auto-fill) and responses.

• Supports custom handlers in TypeScript for complex assertions and logic.
