A browser extension is a piece of software that lives inside Chrome, Firefox, or Safari and changes how a webpage behaves for the user who installs it. It is one of the smallest shipping surfaces for a real software product.
Typically used for
- Productivity tools: text replacement, link cleaners, tab organizers
- AI assistants: a Claude or GPT layer over the pages you visit
- Save-to-tool integrations: clip to Notion, Raindrop, ReadWise
- Power-user shortcuts for a specific SaaS platform
- Internal tools for your team to use across the web on company data
How I scope it
Manifest v3 for Chrome and Edge, with cross-browser support for Firefox where the API surface allows. Store submission and review handled. Self-hosted alternative if you do not want to put it on a public store.
WHY THIS PRICE
What you're actually paying for
A browser extension is software that lives inside Chrome, Firefox, or Safari and modifies how a webpage behaves. Manifest spec, store review, cross-browser quirks. The "small tool" framing hides real engineering.
What's in the work
- Manifest v3 build for Chrome and Edge
- Cross-browser variants for Firefox and Safari where the API allows
- Content scripts, background workers, popup UI
- Settings storage and sync
- Permissions justification for store review
- Store submission and review handling
- Self-hosted distribution as an alternative
- Update path for future browser changes
The value it adds
A browser extension is a distribution mechanism nothing else replicates. Once installed, it runs every time the user opens their browser. For productivity tools and AI assistants, it is the most leverage-per-line-of-code surface available.
