RestIt – A Fast, Lightweight Native HTTP Client

1 restit 0 8/6/2025, 4:31:11 AM

Hi HN,

I’m the creator of RestIt, a fast, native HTTP client built using C++ and ImGui, designed for developers who want a no-frills, high-performance alternative to Electron-based REST clients.

Why I built it: I found many popular REST clients heavy, slow, or overly complex for quick testing and debugging. I wanted something native, lightweight, fast to launch, and extensible – so I built RestIt.

Features:

    Native UI using Dear ImGui

    Fast startup, small binary (~MBs)

    Support for HTTP/S with OpenSSL

    JSON viewer/editor

    Tabbed interface

    Works offline, no telemetry

Platform support: built for Windows and macOS and Linux. Downloads Download: https://restit.app/download

I’d love your feedback! Feature requests, bug reports, or pull requests are all welcome. Happy to answer any questions.

Thanks!
