Home/Services/Chrome Extensions

Live in your customers'
browser.

Custom Chrome extensions that automate repetitive work, enhance the sites your team lives in, or put your product one click from everything your users do. Designed, built, and published to the Chrome Web Store.

Is this you?

The browser is where
work actually happens.

PROBLEM 01

Same clicks, every day

Your team performs the same browser routine dozens of times daily — copying, pasting, switching tabs. An extension turns that into one click.

PROBLEM 02

Your product is a tab away

Users forget tools they have to visit. An extension keeps your product present on every page they browse — the ultimate retention surface.

PROBLEM 03

The tool that doesn't exist

You've searched the Web Store and the extension you need isn't there. That's not a dead end — it's a spec.

The Nexo way

From idea to the Chrome Web Store — reviewed, published, and maintained.

Extensions have their own rules: Manifest V3, permissions review, store policies. I've navigated them — your extension ships compliant the first time.

What's included

Everything you need.
Nothing you don't.

Custom extension development

Built on Manifest V3 with clean, efficient code that passes Chrome's review.

Workflow automation

Scrape, fill, extract, sync — the repetitive browser work your team shouldn't be doing by hand.

Site enhancement tools

Overlay features onto the platforms you use daily — CRMs, dashboards, marketplaces.

API-connected extensions

Extensions that talk to your backend, your product, or third-party services securely.

Web Store publishing

Listing, assets, privacy policy, and the review process — handled to approval.

Updates & maintenance

Chrome changes; I keep your extension compatible and compliant.

How it works

From first message
to one-click workflows.

Fixed quote

Scope, price, and timeline in writing within 48 hours.

Build & sideload test

You test the real extension in your own browser during development — feedback shapes the build.

Publish & maintain

Submitted, approved, live on the Web Store — with updates as Chrome evolves.

Internal tools from $1,200; public store-ready extensions typically $2,000–$6,000. Fixed quote before I start — no surprise invoices, no lock-in contracts.

PROOF

Low competition, high leverage

Extensions are one of the most underused business tools — small builds that save teams hours every single week.

Extension questions? Straight answers.

How much does a Chrome extension cost?

Internal team tools start at $1,200. Public, store-ready extensions with backend connections typically run $2,000–$6,000. Fixed quote before building.

Will it work on other browsers too?

Mostly yes — modern extensions built on Manifest V3 generally run on Edge, Brave, and other Chromium browsers with little or no change. Firefox support can be added if needed.

Can an extension interact with sites like our CRM or a marketplace?

Yes — reading, enhancing, and automating within third-party sites is exactly what extensions do best, within each platform's terms of service.

Do you handle Chrome Web Store publishing?

End to end: the developer account, listing assets, privacy policy, permissions justification, and the review process until approval.

What if Chrome updates break something?

Chrome evolves constantly, which is why I offer light maintenance to keep extensions compatible and compliant — or full handover with documentation if you'd rather manage it in-house.
