Find the bugs
before your users do.
CanaryUsers sends a flock of lifelike AI users through your app on every deploy. They click, type, get confused — and tell you exactly where real people would have bailed.
Three steps to a calmer launch.
Point us at a URL
Drop in a preview deploy, staging, or production link. One line in CI, or paste it in the dashboard. No analytics history needed.
The flock runs your goals
Each canary gets a persona and a goal — sign up, check out, find the docs — then actually works through your UI like a real person.
Fix what broke
Get a ranked, fix-ready list — patch it yourself, or hand the steps straight to your AI coder (Cursor, Claude Code, Copilot) and let it fix them for you. Wire it to every push.
Everything a real user would do — minus the bad review.
Canaries click like people, not scripts.
No brittle selectors to maintain. Each canary reasons about your UI the way a first-time user would — and fumbles in the same places they would.
- Hesitation & rage-click detection
- Works on flows you never wrote a test for
- No test code to keep up to date
See exactly where people give up.
Every form field, every step. CanaryUsers shows the moment a canary got stuck, what it tried, and the thought that made it bail.
- Field-level funnel breakdown
- Confusing-copy flags
- Per-step completion rates
A flock on every pull request.
Wire it into CI and get a flock report as a PR comment. Catch the regression in preview, not in the incident channel.
- GitHub / GitLab PR comments
- Block merges on new bugs
- Compare runs across deploys
The only one that works on day zero.
Blok needs your Mixpanel history. Coframe needs live traffic to optimize against. You have neither when you just shipped. The canaries don't need them.

Don't take our word for it
“Cool & Cute! I tried it : 81/100... 0% of 40 🐥 droppped off!!! OUF 💛”
“This is a good idea”
“Nice thanks!”
“It was a lot easier to understand than the big name scanners and also I am finding some of their checks are hitting a lot of false positives as they try to move their traditional offering into AI space. I don't actually use AI to build my site but I have signed up and will continue using.”
“This is useful 🙏”
“That was genuinely useful — I'd never seen the cookie banner because of my own Brave settings, so I'd completely forgotten to check it."”
“Thank you so much! We’re going to start focusing on our SEO and AEO, we definitely didn’t give them the priority they deserved.”

A quick check is 2 credits; a deep full-app scan is about 40. Need more? Credit packs from $12. Bigger volume or SSO? Talk to us.
Pick how big a flock to send.
A quick check is 2 credits per page. A deep full-app scan, where the flock drives a real browser with a vision pass, is about 8 per page. A bigger flock adds depth (more birds per page), not a bigger per-page bill.
Quick check — a couple of each persona. Great for CI on every push.
Standard run — stable drop-off rates across the personas.
Deep UX dive — maximum coverage and qualitative voices.
With changed-pages-only on (the default), a typical CI push re-scans just 1–3 pages — so a run is usually only a handful of credits.
Let the birds loose.
Your next deploy could use a few hundred friendly testers.
