ApiTab
Local-First API Testing Tool — Browser Extension & Desktop App
Overview
ApiTab is a fast, minimal alternative to Postman for testing and organizing HTTP APIs. It's local-first by design: collections, environments, and history live entirely on your device, with no account required to use it. Everything runs as a browser extension (Chrome, Edge, Brave, Firefox) and as a native Electron desktop app, sharing the same React/TypeScript codebase and Zustand-backed storage layer.
For teams, an optional Laravel + Sanctum backend adds account login and team workspaces — collections can be shared with a team (role-aware: owners/admins can edit for everyone, plain members get a local-only read-through view), and individual environment variables can be flagged to sync to a per-team shared pool, all while environments themselves stay device-local by default.
Key Features
- Full request builder — methods, params, headers, auth (bearer/basic/API key), JSON/form/urlencoded bodies, and response viewer with headers, cURL, and code snippet generation.
- Environments with
{{variable}}interpolation, plus a pre-request/post-response JavaScript sandbox exposing apm.*-compatible scripting API, so pasted Postman scripts run unmodified. - Import Postman Collection (v2/v2.1) and Environment exports directly, alongside ApiTab's own cURL and JSON import/export formats.
- Team workspaces: shared collections with owner/admin/member roles, a per-team shared-variable pool for opted-in environment variables, and a sidebar that visually separates your personal workspace from each team's shared space.
- Cross-platform desktop installers (Windows, macOS, Linux) built and published automatically via GitHub Actions on every tagged release.
