FAQ

Questions

Will you publish it to the Chrome Web Store?

We prepare the listing text and screenshots. Publishing happens under your own Chrome Web Store developer account, which Google charges a one-time registration fee for, so you own the listing.

Do I own the code?

Yes. You get the full source code and the packaged extension.

What does MVP mean here?

The core job the extension exists for, working reliably. Nice-to-have settings and extra screens can come later.

Does it work in Microsoft Edge?

Yes. Edge runs Chrome extensions, and every build is tested in both browsers.

Have you built extensions before?

Yes. Kanto Labs makes Keylamp, a browser extension that highlights many keywords at once on any page.
