Introduction

httpYac executes requests defined in .http and .rest files, the same plain-text format used by the popular VS Code REST Client and JetBrains HTTP Client. It comes as a CLI and a VS Code extension, and supports HTTP, REST, SOAP, GraphQL, WebSocket and gRPC requests, according to the README.

Files can include variables, environments, OAuth2 token generation and JavaScript blocks for setup and assertions, so the same file serves for manual exploration in the editor and automated runs in CI with httpyac send.

A Docker image (ghcr.io/anweber/httpyac) makes CI use easy. Its last release was 6.16.7 in March 2025, with commits continuing into 2026.

In the quality loop it fits API checks for teams that keep requests next to code.

The source code is at AnWeber/httpyac on GitHub under the MIT licence, with about 890 stars; the most recent commit was on 4 March 2026.
