DevBooster

Select a code snippet on any web page and DevBooster will check it before you paste it into your editor.

DevBooster is an AI browser extension and code assistant that validates, optimizes, translates and documents code you find online.

It translates code across 100+ languages, gives step-by-step explanations and supplies ready-to-use samples.

The free Lite plan covers the basics for one instance, which suits beginners who mainly want explanations.

Pro costs $59 a year and supports up to 9 instances.

It adds code optimization, auto-generated documentation, inline comments, a live AI chat, custom actions, reusable templates, a snippet library and sync across devices, plus premium support and early access to new features.

Ultimate costs $99 a year, includes everything in Pro and raises the limit to 12 instances.

The catch is that the free tier is narrow.

Documentation and optimization, two of the more useful extras, sit behind a paid plan.
