API development at the speed of Go

Heapi is a high-performance, native API client designed for developers who demand speed, terminal integration, and local-first reliability. No Electron, no accounts, just pure efficiency.

Native Go Engine

Powered by Go's high-concurrency net/http. Execute requests with real parallelism and sub-second response times.

Terminal, Not Just a Tab

Integrated multi-tab ConPTY terminal. Run your DB queries, Docker commands, or shell scripts side-by-side with your API calls.

Git-Native YAML

Your collections are pure YAML. Treat your APIs like code—commit, branch, and merge without JSON conflict nightmares.

Recursive Variables

Sophisticated interpolation engine (V.I.E) with multi-level recursive resolving for complex environment setups.
