About Template
Built with Go, Python, TypeScript, and Svelte, it provides an admin dashboard for team management, a request inspector for analyzing and replaying HTTP requests, and secure SSH-based remote port forwarding. Designed for small teams, Portr offers a cost-effective tunneling solution with full infrastructure control and data sovereignty. The request inspector lets developers examine incoming requests, replay them for debugging, and understand webhook payloads, making it valuable for testing payment gateways and third-party integrations.
Supporting HTTP, TCP, and WebSocket connections, Portr handles diverse scenarios from web applications to database connections and real-time communication. Perfect for teams working on microservices, webhook integrations, or mobile backends, it provides commercial-grade tunneling with open-source transparency and control.
