ApiTab
API collections your
team can actually share
ApiTab is the backend behind the ApiTab browser extension — token-based auth, team workspaces, and last-write-wins sync for your collections and environments.
Install ApiTab in your browser
The companion browser extension talks directly to this server — register, join a team, and your collections sync automatically.

Built for teams, not tabs
Everything the extension needs 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 the extension.
Team workspaces
Create teams, add members, and share collections and environments across everyone in the workspace.
Collections & environments
Full folder/request trees and variable lists stored as-is — mirroring the extension's 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 extension needs, nothing extra.
Built in the open, auditable by anyone
Both the server and the browser extension are fully open source — read the code, run it yourself, or send a pull request.
Browse the source
Every line that touches your data is public — no closed-source binaries, no minified black boxes.
Contributions welcome
Found a bug, have an idea, or want to add a feature? Issues and pull requests are genuinely welcome — this is a community project.
No hidden security risk
Open source means nothing is hidden — no telemetry, no obfuscated code, no undisclosed network calls. Anyone can verify exactly what the extension sends and where it goes, and self-host the backend to keep full control of the data.
