Volt - The API client that respects you. 4 MB, git-native.

by•
Volt is a complete API development toolkit in a single ~4 MB binary. Built from scratch in Zig with zero dependencies. Plain-text .volt files live in your git repo — no account, no cloud, no telemetry, no Electron. Requests, testing, mocking, load testing, import/export, a web UI — everything Postman does in 1/100th the size. Starts in <10ms, uses 5 MB RAM. Import from Postman/Insomnia/OpenAPI in one command. Export to 18 languages. Built-in CI/CD with JUnit reports.

Hey Product Hunt! I built Volt because I was tired of waiting for Postman to load. Every API client I tried was either a 500 MB Electron app that needed an account, or a CLI tool that couldn't do testing. Volt is the full package in a 4 MB binary: requests, collections, testing, mocking, load testing, import/export, a web UI — all from a single file you drop on your PATH. It's built entirely in Zig with zero dependencies. The .volt file format is the key idea: your API requests are plain text files that live in git alongside your code. No proprietary JSON blobs. No cloud sync conflicts. Just files you can read, diff, and review in PRs. If you're switching from Postman or Insomnia, volt import makes it a one-command migration. Would love your feedback!
