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.
