02 Why DevFlow exists

Websites break.
We absorb the break.

Websites change constantly. Layouts shift, anti-bot systems update, SEO rules evolve, performance degrades. Teams that depend on web quality end up maintaining scanners instead of fixing issues.

DevFlow runs that layer for you. When a site changes, it is our problem to solve, not yours.

01Security vulnerability appearswe detect it instantly
02SEO ranking drops overnightstructure stays stable
03Page speed degradeswe flag the regression
04Accessibility breaks for userswe catch it before they do
03 Infrastructure

Every scan takes the same six-stage path: receive, route, render, extract, analyze, deliver. Everything between is operated and monitored by us.
