Installation guide

  1. 1Open the downloaded .dmg and drag ApiTab into Applications
  2. 2Open Terminal (Spotlight → type "Terminal") and run: xattr -cr /Applications/ApiTab.app
  3. 3This is expected for unsigned builds — macOS quarantines anything downloaded from a browser, which can make it say the app is "damaged" even though it isn't. The command above clears that flag and only needs to be run once.
  4. 4Open ApiTab normally from Applications or Launchpad
  5. 5If you instead see an "unidentified developer" warning (a softer prompt than "damaged"), right-click the app → Open → confirm Open in the dialog — only needed the first time
  6. 6Not sure of the install path? Run ls /Applications | grep -i apitab to confirm where it landed

Why ApiTab

Built for teams, not tabs

Everything ApiTab's apps need to keep collections and environments in sync across your team — nothing more.

Token auth

Email/password auth with Sanctum bearer tokens — no cookies, no CORS headaches for either client.

Team workspaces

Create teams and assign shared collections to specific teammates — recipients accept or decline from a live preview, and removing a member revokes their access immediately.

Collections & environments

Full folder/request trees and variable lists stored as-is — mirroring the client apps' types field-for-field.

Conflict-safe sync

Last-write-wins, enforced server-side. Stale writes get a 409 and the current copy back.

Zero-setup storage

Ships with SQLite for local dev — no external database to provision before you get started.

Open REST API

A small, predictable API under /api — everything the apps need, nothing extra.

Open Source

Both apps are open source

The ApiTab desktop app and browser extension are both fully open source — read the code, run it yourself, or send a pull request.

Desktop app

Electron + React, MIT licensed. Every line that touches your data is public.

Repo Issues PRs

Browser extension

Same MIT license, same transparency — no closed-source binaries, no minified black boxes.

Repo Issues PRs

No hidden security risk

Open source means nothing is hidden — no obfuscated code, no undisclosed network calls. Both apps do send a lightweight, anonymous usage ping (session length, IP or account id if you're signed in — nothing else) that powers the usage chart below; the code for it is public like everything else, so you can verify exactly what it sends.
