How it works

Built for non-technical testers

Stakeholders click a button — no logins, no tutorials

Clients, business stakeholders, and end-user testers don’t need a Ybug account, training, or a "how to file a bug" doc. They click the widget, draw on what looks off, type a sentence, and submit.

  • No login or signup for reporters — anyone can submit
  • Works on desktop, tablet, and mobile
  • 19 supported languages with fully customizable labels
Custom forms for UAT

Structured input — not free-text guessing games

Add the fields your acceptance criteria actually need: severity, area, NPS, test case ID, expected vs. actual. Ybug also pulls all the technical metadata in the background, so testers stay focused on what they saw.

  • Custom fields: severity, priority, NPS, test case, area, anything
  • Browser, OS, viewport, URL, and console logs captured automatically
  • Pass user role, environment, or build via the JS API

Sign-off without spreadsheets

Close the loop with testers — and with stakeholders

Reply directly from Ybug and the message lands in the tester’s inbox. Auto-confirmations let stakeholders know their feedback was received, and resolution emails go out when an issue is fixed — so UAT sign-off doesn’t live in a side spreadsheet.

  • Reply from the dashboard — emails go straight to the tester
  • Auto-confirmation when feedback comes in
  • Resolution emails when an issue is fixed and closed

Hand off to engineering

Push real bugs straight to dev — with the context already attached

No more PMs acting as a copy-paste relay between testers and devs. Triage UAT feedback in Ybug, then push the real bugs into Jira, ClickUp, GitHub, or wherever your team works — visuals and metadata included.

  • 25+ integrations: Jira, ClickUp, Trello, Asana, GitHub, Slack, and more
  • Auto-push or triage-first — pick what fits each project
  • Screenshots, console logs, and metadata travel with every report

Keep teams informed automatically

Send automatic email confirmations when feedback is received and notify users when their input is resolved.

Frequently asked questions

Do UAT reviewers need a Ybug account to leave feedback?

No. Reviewers click the widget on the staging site and submit annotated feedback with no signup, no password, no portal. The lower the friction, the more useful the UAT signal.

Can we collect structured input from reviewers — priority, area, sign-off?

Yes. Add custom form fields to the widget for priority, module, sign-off status, or whatever your UAT process needs. Reviewers fill in structured input instead of vague paragraphs.

Can we run UAT on a staging site that’s behind a login?

Yes. Install the widget on staging the same way you would on production. For environments behind VPN or strict CSPs, Native screenshots capture securely without sending data to an external renderer.

Will the feedback widget slow down our site or app?

Not at all. We’ve built Ybug to be lightweight and load asynchronously, so it won’t interfere with your page load speeds or user experience. You get the feedback you need without the lag.

Does it integrate with our existing tools?

Yes. Ybug integrates with Jira, Slack, GitHub, ClickUp, Trello, and many more. Feedback and bugs can go straight into the tools you already use.

Can our users submit feedback without logging in?

Yes. Users can submit visual feedback and bug reports directly from your app in a few clicks – no signup or login required. Less friction means more useful feedback.
