Browser extensions

The gap in the tool you use all day

Every SaaS product has one. A step your team repeats forty times a day that the vendor will never fix, because it only matters to you and eleven other companies.

Nobody is going to build a whole product for that. An extension is the right size of answer — it lives inside the tool your team already has open, and it can be shipped in under a month.

Why us specifically

We have published six extensions of our own across Chrome, Edge, Firefox and the Microsoft Office add-in store, under JSKAPPS. They are live, they have users, and they went through store review — which rejects most first submissions, usually over privacy disclosures.

That last part is where most first-time extension projects stall. We have made those mistakes already, on our own products, at our own cost.

What we build

Workflow automation inside a SaaS tool · data capture from pages your team works in · internal tools that need page context · Google Workspace add-ons · Microsoft Office add-ins · productivity tools for your own customers.

How it goes

Week 1 — scoped. What it does, what it touches, what permissions it needs and why. Permissions matter: every extra one slows review and worries users.

Weeks 2–3 — built. Manifest V3, for the browsers you choose.

Week 3–4 — submitted. We handle the listing, the privacy disclosures and the review correspondence. Store review time is outside anyone’s control; we plan for it rather than promise around it.

Then it is yours. Source code and store ownership transferred to your account.

What it costs

From $4,500, two to four weeks including review.

Store developer account fees are paid by you, in your name, so the listing is yours from day one. That is a one-off fee of a few dollars, and it matters more than it sounds — an extension published under a vendor’s account is an extension you do not control.
