HTTP testing tool with HTTP/2, HTTP/3, and WebSocket support
Cross-platform API testing tool inspired by Postman, featuring HTTP/2 and HTTP/3 support, collection-scoped environments, automated testing, and significantly lower memory usage.
Pororoca is a cross-platform HTTP testing tool designed for developers who need advanced protocol support without sacrificing performance. Built with C# and Avalonia, it runs on Windows, macOS, and Linux while consuming two to three times less memory than comparable tools.
The tool provides full support for HTTP/2 and HTTP/3 protocols alongside traditional HTTP/1.1, plus native WebSocket testing. Collection-scoped environments simplify workflow management, while secret variables protect sensitive data. Automated testing capabilities enable CI/CD integration, and fast startup times keep developers productive.
Unlike cloud-synced alternatives, Pororoca stores all preferences, collections, and environments locally on your machine. No telemetry, no remote servers, no data sharing. Full Postman import/export compatibility ensures easy migration, allowing teams to switch without losing existing work. The multilanguage interface supports global development teams, while the open-source codebase ensures transparency and community-driven evolution.
When teams consider Pororoca, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
HTTP/3 API Development
Test and validate next-generation HTTP/3 endpoints with native protocol support, ensuring compatibility before production deployment
Performance-Critical Testing
Run comprehensive API test suites on resource-limited CI/CD runners without memory bottlenecks
Postman Migration
Import existing Postman collections directly and continue testing workflows with improved performance and privacy
WebSocket Integration Testing
Validate real-time WebSocket connections alongside REST APIs in a unified testing environment
No. Pororoca stores all data locally on your machine. No preferences, collections, environments, or telemetry are sent to remote servers.
Yes. Pororoca offers full import and export compatibility with Postman, allowing seamless migration of existing collections and environments.
HTTP/3 is supported on Linux and Windows 11 or later. HTTP/2 requires Windows 10 or later on Windows systems. macOS supports HTTP/2.
Pororoca typically uses two to three times less memory than Postman, making it suitable for resource-constrained environments.
Yes. Pororoca includes automated testing capabilities, allowing you to integrate API tests into CI/CD pipelines.
