Actions, Not HTTP Noise

DevTools shows you 47 individual requests. Brakit groups them by what the user actually did. One action, every request inside it, with duplicates flagged and redundancy calculated automatically.

How It Works

Your app runs. Brakit watches every request, query, and response, surfaces patterns you'd never see in code review, and helps AI fix them.

1
Your app handles a request
A page load, form submit, or API call.
2
Brakit captures everything
Every HTTP request, database query, and external fetch. Zero config.
3
Patterns surface instantly
Duplicate queries across pages, redundant fetches, endpoints connected in ways you didn't expect.
4

Duplicate query: SELECT users runs in 3 pages. Extracted shared loader with caching.
3 pages → 1 cached fetch
Pattern resolved: 3 duplicates → 1 cached fetch

Know exactly where time goes

Every endpoint timed. Every query measured. Slow pages jump out before your users notice.
