About API Tester & HTTP Client
The API Tester & HTTP Client is a comprehensive tool for testing REST APIs and HTTP endpoints directly in your browser. Send requests with any HTTP method, configure custom headers and query parameters, add authentication (Bearer token, API key), and inspect detailed responses including status codes, headers, body content, and performance metrics. Generate code snippets in 16+ programming languages including C#/.NET, Curl/Bash, Dart/Flutter, Go, Java, JavaScript, Kotlin, Node.js, Perl, PHP, PowerShell, Python, R, Ruby, Rust, and Swift. Features an intuitive auto-expanding interface for headers and parameters, multiple body formats (JSON, Plain Text, Raw Text, Form Data), and local request history. All requests are processed securely through our API proxy for maximum privacy.
Why use a API Tester & HTTP Client?
Testing APIs traditionally requires desktop applications like Postman or command-line tools like cURL. This browser-based API tester provides a lightweight, privacy-focused alternative with powerful code generation capabilities. Instantly generate production-ready HTTP request code in 16 programming languages - perfect for documentation, tutorials, or implementing API calls in your projects. View formatted JSON responses, measure response times, inspect headers, and maintain a local history of recent requests. The streamlined auto-expanding interface eliminates manual row management for headers and parameters. Supports all HTTP methods, multiple body formats (JSON, Plain Text, Raw Text, Form Data), and flexible authentication options without storing any sensitive data on external servers.
Who is it for?
Essential for frontend and backend developers testing API endpoints, DevOps engineers debugging microservices, QA testers validating API integrations, and API developers building and documenting REST APIs. Perfect for technical writers creating API documentation with code examples, developers learning new programming languages, teams sharing API integration code across multiple tech stacks, and anyone who needs a quick, privacy-first alternative to Postman with built-in code generation for 16+ languages.
