What this business actually is
Extensions solve focused problems inside browsing workflows: email tracking, tab management, LinkedIn helpers, price monitors. Development takes days-weeks versus months, making them ideal product validation training grounds.
Monetization runs through extension marketplaces' payment APIs or license keys upgrading free versions. Successful extensions convert 1–5% of users to $3–$10/month plans; 20,000 users becomes real money.
Platform risk is real — Chrome's Manifest V3 shifts have killed categories. Portfolio across browsers (Firefox/Edge ports are cheap) hedges dependency on one gatekeeper.

The honest balance sheet
Advantages
- · Weeks-not-months build cycles teach product skills fast
- · Distribution built into web stores
- · Cheap portfolio experiments with real users
Disadvantages
- · Single-platform dependency risk
- · Low awareness ceiling per tool
- · Permission-request friction scares installs
Common mistakes
- · Requesting broad permissions terrifying privacy-conscious users
- · No upgrade path monetizing popularity
- · Building clones without meaningful differentiation
Legal considerations
Store policies restrict data collection heavily — privacy permissions requests get audited; trademark terms in names risk takedowns.
