Catch what your AI edit quietly broke.
AI builders let you ship in minutes — and regress in seconds. You ask for one change; the model rewrites half the app and silently breaks a button, a form, or a whole flow. Relvato re-checks your app after every change and shows you exactly what moved, vanished, or stopped working — against a baseline you approved.
The regressions AI edits leave behind.
Every one of these is a change the model made without telling you — the failure mode of building by prompt.
Visual regression
A prompt tweaked the CSS and now the hero overlaps, the grid collapses, or a section shifts off-screen. Caught pixel-for-pixel against your approved baseline.
Structure drift
The AI rewrote a component and a button, a form field, or a whole section quietly disappeared — flagged even when the page still looks fine.
Broken flows & links
Sign-up, checkout or a key click stops working; an internal link or image 404s after a route changed. Relvato drives the real flow in a browser, not just a ping.
Runtime & console errors
An edit throws a JavaScript error, a blank white screen, or a failed backend call. Scanned in a real browser, as a logged-out visitor sees it.
Mobile layout breakage
It looks right on your laptop and breaks on a phone — the most common vibe-coding regression. Checked on desktop and mobile every time.
AI-output regression
If your app embeds its own chatbot or generator, send it a fixed prompt and get alerted when its answers error out, empty, slow down, or drift from a golden reference.
No install. Just a baseline and a browser.
Relvato watches your app from the outside, the way your users see it — so it works on any AI builder, on the free subdomain or your own domain.
Verify your app
Add one meta tag to your app’s page head — no install, no code to maintain. Or just ask the AI to add it. Works on any lovable.app / bolt / v0 URL or a custom domain.
Approve a baseline
Relvato screenshots and fingerprints your key pages, desktop and mobile. You approve how it should look and what should be there — that’s the reference.
Connect GitHub — re-checks on every AI edit
Connect your GitHub repo in one click and Relvato adds the webhook for you — no config, no copy-paste. From then on every push re-checks your app in a real browser against the approved baseline. Since Lovable, Bolt and v0 commit every change you prompt, every code update is caught automatically (a scheduled check runs as a safety net too).
Alerts with the diff
When something changed unexpectedly you get the exact page, the changed region, and what moved — so you can tell a real breakage from an intended redesign at a glance, and approve or fix.
Catch a slowdown your real visitors feel
An AI-built app can pass in the lab and still be slow for real users. Relvato's cookieless RUM beacon measures Core Web Vitals from your actual page loads — grouped by page type and device — so a regression shows up before your rankings do.
Loading — LCP
Largest Contentful Paint: how quickly the main content appears.
Responsiveness — INP
Interaction to Next Paint: how snappy the page feels to taps and clicks.
Stability — CLS
Cumulative Layout Shift: how much the layout jumps while it loads.
One-line beacon
Paste a tiny cookieless script — or let your AI add it. No cookies, no personal data, no IP stored; it aggregates the p75 per page type and device.
Any AI builder. Any deployed app.
If it’s a live URL, Relvato can watch it. No SDK, no framework lock-in.
Monitoring AI-built apps, answered.
Do I need to install anything?
No. You add one meta tag to your app to verify you own it — Lovable, Bolt and v0 all let you edit the page head, or you can just ask the AI to add it. Everything else runs from Relvato’s side.
How does it catch every AI edit?
Connect GitHub in one click — Relvato adds the push webhook for you (no copy-paste). Lovable, Bolt and v0 commit every change you prompt, so every AI edit triggers a re-check automatically. No repo connected? A scheduled check still runs.
Does it work on the free *.lovable.app URL?
Yes — the meta-tag verification works on the built-in subdomain and on a custom domain alike.
Can it check flows behind a login?
Yes, with a dedicated test account. Point Relvato at a test login (Supabase or otherwise) and it runs the flow as a signed-in user.
Won’t every intended change get flagged?
No — you approve a new baseline in one click when a change is intended, so only unapproved differences alert.
