Sound familiar?
You have a workflow idea.
No one builds it for you.
Generic extensions almost-but-don't-quite work for your specific use case.
Hiring a dev agency costs $10,000+ and takes 3 months.
Freelancers on Fiverr ghost you mid-project.
You don't have time to learn to code — you have a business to run.
Extly builds it for you.
Tell us what you need. We build a custom browser extension to your exact spec — one that automates exactly the workflow you described, nothing more, nothing less.
The process
From idea to working extension in 4 steps.
Describe your idea
Fill out a short brief — what browser workflow do you want to automate? No technical knowledge needed. Plain English works fine.
We scope and quote
Within 24 hours, you get a clear fixed-price quote. No hourly rates, no scope creep, no surprise invoices at the end.
We build it
Our devs get to work. You receive progress updates. Most extensions are ready within 3 to 7 business days.
Install and use it
We deliver the extension file and walk you through installing it in your browser. You own the full source code — forever.
What you get
Everything you need. Nothing you don't.
Built to spec
Your workflow. Your rules. 100% custom.
No templates, no shortcuts. We build your extension from scratch around the exact task you need done — whether it's scraping data, automating clicks, injecting UI into a third-party site, or syncing with your own tools.
- → Data extraction from any website
- → Automated form-filling & actions
- → Custom popups and sidebars
- → Integration with your existing APIs
You own it
Full source code delivered. No lock-in.
When we deliver, you get the complete source code — not just a binary. Install it yourself, modify it, pass it to another developer. We don't hold your extension hostage to a subscription.
- → Complete source code ownership
- → Works without any Extly account
- → No recurring fees for the extension itself
- → Optional maintenance plans available
