AI Analysis

●MidCozyShip It

Nice visit-limiting mechanic, but LeechBlock already handles schedules and quotas better.

Strengths

•Manifest V3 architecture ensures compatibility with future Chrome updates and security policies.
•Puppeteer integration tests verify blocking logic instead of relying on manual checks.
•React 19 and TypeScript stack ensures type safety across extension background scripts.

Weaknesses

•Crowded category dominated by LeechBlock and Freedom with deeper feature sets.
•Single mechanic limits utility for users needing strict total daily caps.

Post Description

Most blockers cut you off completely. Once takes a lighter approach. You add the sites you find distracting and it lets you visit each one once per hour, so you can check in without falling down a rabbit hole. Easy, free, and open-source.
