Visual feedback & bug reporting for Lovable apps
Add a feedback button to your Lovable app with one prompt. Clients and testers mark up a screenshot right in the app, and each report arrives with the URL, browser, viewport, and JS console logs. Then Lovable’s agent can read the report and fix it.

Feedback that keeps up with
how fast Lovable apps change
Drop-in feedback widget
Your client points at the bug instead of describing it
Your client opens the app, spots a form that won’t submit, clicks the widget, circles the button, and hits send. No Lovable account, no screen-share to explain it, no screenshot thread in Slack. You get an annotated screenshot of exactly what they saw.
- One click to capture a page of your Lovable app with annotations
- No Ybug account or training needed for clients and testers
- Works in Lovable’s preview and on your published app
Receipts on every report
Every bug report comes with the console errors
“The signup doesn’t work” gives Lovable nothing to go on. Ybug stamps each report with the URL, browser, OS, viewport, and screen size, plus the JS console errors from the moment it was sent. That’s the context a fix starts from.
- Browser, OS, viewport, and URL captured automatically
- JS console errors captured with every report
- Clear context for sign-up flows, forms, and dashboards
Fixed in the same chat
Let Lovable read the report and fix it
Connect Ybug to Lovable as an MCP server, and its agent can read your reports: the description, page URL, browser, and console errors. Ask it to fix the signup bug from this morning, and it changes the project in the same chat. See the setup guide.
- Connects with OAuth — no API keys to paste
- Reads reports and console logs on BASIC and up
- Adds notes and resolves reports on STARTUP and up
Close the loop
Ask your tester, keep the answer on the report
Need to know which account they used or what they expected to happen? Reply from the Ybug report and your message lands in their inbox. Their answer comes back to the same report, next to the screenshot.
- Reply from inside Ybug, delivered as a normal email
- Tester replies pin back to the same report
- No more chasing context across email, chat, and task lists
On-brand widget
A widget that fits the app you designed
The feedback button shouldn’t look bolted on. Match colors, fonts, copy, position, dark mode, and language, or hide the default button and ask Lovable to open Ybug from your own button via the JS API.
- Custom colors, fonts, copy, position, and dark mode
- 19 languages with fully editable labels
- Trigger from your own button via the JS API
Why teams building in Lovable choose Ybug
For agencies and product teams shipping client apps, MVPs, and internal tools in Lovable, and reviewing them with people who don’t live in the editor.
Feedback your agent can act on
A report with a screenshot, URL, and console errors is something Lovable can work with. “It’s broken” is not.
Preview and production alike
The widget runs in Lovable’s preview as soon as it’s added, and on your lovable.app address or custom domain once you publish. No domain settings in Ybug.
Client review without extra seats
Clients and testers don’t need a Lovable or Ybug account. Anyone on the page can report, and reporters are always free and unlimited.

Here’s what our users say
Excellence Website Widget
Ybug is intuitive and easy to use for someone who by nature is not technical. It is quite flexible - where some tools are limited to bug reporting, we use Ybug not only to report bugs, but to also solicit feedback on specific pages and products. Ybug also provides an invaluable screenshot that enables a customer to show us the exact issue. On top of this, service is excellent.
Neil R.
Founder & President at TrophyCentral
Easy to use and integrates nicely with our PM tools
There are 3 main features that I like the most: 1. Unlike other feedback software that we used before, Ybug is easier to launch for each project. It typically takes 2-3 minutes to add a project to Ybug and start sending feedback. 2. It has a nice Chrome extension, which allows to capture screenshots on any website and tag to any project that we are currently working on. 3. Ybug integrates nicely with Teamwork (our PM tool), so each feedback that is submitted on the development websites - is automatically created as a task for our development team.

Lovable feedback tool — frequently asked questions
How do I install Ybug on a Lovable app?
Create a Ybug project and copy the widget snippet. In your Lovable project, ask the agent to add the snippet so it loads on every page, just before the closing
</body> tag. The feedback button appears in the preview right away, and on your live app after you publish.
Can Lovable fix the bugs reported in Ybug?
Yes. Add Ybug to Lovable as a custom MCP server under Connectors and sign in with your Ybug account. Lovable’s agent can then read your reports, including the page URL, browser, device, and console errors, and change your project to fix them. Reading reports needs the BASIC plan; adding notes and changing the status needs STARTUP.
Does the widget work in Lovable’s preview?
Yes. Once the snippet is in, the feedback button shows in the preview, so you can try it before publishing. Reports sent from the preview list the preview address as their page URL. After you publish, it works on your lovable.app address and on a custom domain, with no domain settings in Ybug.
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.
Does it work on mobile and iOS Safari?
Yes. Every report includes the URL, browser, OS, viewport, and screen size, so mobile layout bugs arrive with the context your team needs to reproduce them. Testers can report from iOS Safari, Android Chrome, and modern desktop browsers.
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.
