I will build a custom chrome extension to automate your web tasks
Jeremy H.
About this gig
Doing the same clicks every day? I'll build a browser extension that does it for you.
What I can build:
- auto-fill forms, click buttons, extract data from pages
- popup tools, shortcuts and page enhancements
- API integrations: OpenAI, Google Sheets, your own backend
- fixes and updates for existing extensions (Manifest V3)
My process:
- you describe the task in writing
- I build the extension
- I test it on the real website
- you get the full source code and a step-by-step install guide
Works on Chrome, Edge and Brave. Firefox on request.
Custom project? Message me before ordering and I'll reply with a clear quote.

Hi, I'm Jeremy, founder of Simplifio. I build small tools that remove repetitive work: Chrome extensions and Tampermonkey scripts that automate your browser, custom Notion workspaces, Excel VBA and Google Sheets automations, web scraping into clean Excel files, and Discord bots. Every project comes with full source code and a written guide. My process: we clarify your need in writing, I build, I test, I deliver. Message me before ordering and I'll reply with a clear quote.
FAQ
Can you publish it on the Chrome Web Store?
Yes, with the Advanced package I prepare everything for the store. Publishing needs your own developer account (a one-time $5 fee paid to Google).
Can you write a Tampermonkey userscript instead?
Yes. For small automations on one website, a Tampermonkey or Violentmonkey userscript is often faster and cheaper than a full extension. I'll tell you which option fits best before you order.
Will it work on Firefox and Edge?
Edge, Brave and Opera run Chrome extensions directly. A Firefox version needs a few changes: tell me in your message and I'll include it in the quote.
