Small Chrome extensions that do one job.

ExtLab builds focused tools for Chrome on Manifest V3. Each has a free version, and none needs an account.

Extensions

The first extensions are on their way.

They will appear here when they reach the Chrome Web Store. Until then, the guides below are free to read.

One job each
Each extension does one thing, and asks only for what that needs.
No account
Install and use it. A paid license is one key, with no sign-up.
Your data stays yours
Tabs, URLs and searches stay in your browser. They are never sent to us.
