I will build you a custom chrome extension using claude code
David B
About this gig
You know exactly what you want your browser to do - a workflow you repeat by hand, a button that isn't there. I build it.
Custom Chrome extensions in Vanilla JavaScript, HTML, CSS, Manifest V3. No frameworks, no bloat.
PROOF: I built ThoughtFold, live on the Chrome Web Store with over 100 real users. I handled development, packaging, submission, and license validation via a Cloudflare Worker myself.
WHAT YOU GET: A ZIP file, loaded into Chrome via Developer Mode in about 30 seconds. Every order includes an Installation Guide and a Chrome Web Store Submission Guide as PDFs.
WHAT THIS ISN'T: I don't submit to the Chrome Web Store for you, and I don't build servers or SaaS backends. One-time build, not a maintenance contract.
THREE TIERS: Basic - one clear function. Standard - full extension with storage and settings. Premium - external API, Cloudflare Worker, license layer.
Personal use is included. Add Commercial License to sell or use this in a business.
Human-built, AI-accelerated. I use Claude Code and other AI tools to move fast, the same way I built ThoughtFold. Everything ships reviewed and tested by me.

Know what you want built, but not how to build it? I can help.
I'm David. My latest project, ThoughtFold, is a Chrome extension that helps people tame browser tab overload. Launched in May 2026, it already has over a hundred real users. No bloat, no tracking, no surprise charges. Just a tool that does its job and stays out of your way.
That's how I approach every project. Describe the problem, and there's a good chance I can build the solution.

FAQ
What do you need from me to start?
A clear description of the trigger, action, and outcome you want. Mention any specific website, API, or credentials involved. I'll send a short intake brief before starting so nothing gets missed.
What do I actually receive?
A ZIP file with your finished extension, plus two PDF guides: step-by-step installation instructions and a Chrome Web Store submission guide. You load it into Chrome yourself - about 30 seconds.
Do you submit the extension to the Chrome Web Store for me?
No, that's not part of this gig. Chrome's review process is slow and outside my control. You get a working ZIP plus a guide to submit it yourself whenever you're ready.
Can I sell this or use it in my business?
Not under the base price. Every package includes a personal use license only. If you want to sell, redistribute, or use the extension in a business, add the Commercial License extra.
What's covered under revisions?
Revisions cover the extension not matching the scope we agreed on at the start, not new features added afterward. Anything outside original scope is a new order, not a revision.
What can't you build?
Anything needing a full backend, database, or ongoing server infrastructure beyond a single Cloudflare Worker, or third-party OAuth you haven't set up yourself. This is a one-time build, not a maintenance contract.
Why Vanilla JavaScript instead of a framework?
Frameworks add weight an extension doesn't need. Vanilla JS, HTML, and CSS keep it lightweight, fast to load, and simple to maintain, no build step required for small changes later.
