What each one is
Plasmo
Plasmo is a framework for building browser extensions, the small add-ons that run inside Chrome, Firefox, Edge and similar browsers. Based on its topics and description, it is written in TypeScript and is aimed at developers who want a structured setup instead of wiring up a bundler and manifest by hand. The README was empty in the supplied material, so details beyond the repository metadata are unverified.
WXT
WXT is an open-source framework that helps developers build web extensions (add-ons for browsers like Chrome). It handles project setup, a development server with hot module replacement and fast reload, and TypeScript support, so developers spend less time on build configuration. The README describes it as similar to Nuxt, but for web extensions.

Not ideal for
Plasmo
- People who only want to use an existing extension rather than build one, since this is a developer framework
- Developers who need documented behavior for specific features, because the README was not available to verify them
WXT
- People who only want to use an existing extension rather than build one, since this is a developer tool
- Developers who want to write extensions with no build step at all, since WXT is built around a bundler workflow
- Beginners with no JavaScript or TypeScript experience, since the README assumes familiarity with web development
Trade-offs
Plasmo
- The README supplied was empty, so feature claims could not be checked
- Browser extension APIs and store rules change over time, so verify current compatibility yourself
WXT
- The README is truncated and does not detail browser-specific limits or edge cases
- Browser extension platforms change over time, so projects may need upkeep as standards shift
- Documentation is mostly on an external site, so the README alone gives limited setup detail
