Collections & requests
Multiple named collections, each with saved requests. Pick a row to load method, URL, headers, and body into the editor.
Your APIs, one hive
A native REST client for sending requests, organizing collections, and importing OpenAPI.
Built for real API work
Sidebar collections, saved environments, and a focused editor.
Environments & persistence
Per-collection environments with base URL and variables. Everything is stored as JSON under your user config directory—auto-saved on exit, with Save all when you need it.
OpenAPI 3.x import
Import JSON specs into a new collection—one request per operation. Path {id} placeholders become {{id}} for variables. Fetch from a URL or load a local file.
HTTP & HTTPS
GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS. Custom headers, raw JSON body, response status and headers, pretty-printed JSON bodies.
Non-blocking UI
Send and cancel on a worker thread so the interface stays responsive while requests run.
Light & dark
Material-style theme with system-aware light/dark support and optional overrides via environment variables or CLI flags.

Build
APIkulture uses CMake, Slint, and optional OpenSSL for HTTPS. See the repository README for full prerequisites and platform notes.
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build .
./apikulture
Need the Slint C++ SDK? Set SLINT_DIR to your extracted SDK, or let CMake fetch Slint (Rust toolchain required). On Linux, you may need LD_LIBRARY_PATH so libslint_cpp.so is found—details are in the Slint releases and project README.
