Userback
Replaceable in one session with an AI coding agent.
Visual bug reporting: a widget lets someone draw on the page, and the report arrives with a screenshot, the console log and the browser details attached.
Build a visual bug reporter. STACK - A small script, html2canvas or the Screen Capture API, one endpoint, object storage CAPTURING - html2canvas renders the DOM without asking permission; the Screen Capture API is sharper but prompts - Offer the first by default and the second as an option ANNOTATION - Draw a rectangle or an arrow on a canvas over the screenshot before sending WHAT TO ATTACH AUTOMATICALLY - URL, viewport, coarse browser and OS bucket - The last twenty console entries, captured by wrapping console methods at load - Failed network requests from a PerformanceObserver - That context is what turns "it is broken" into a fixable report PRIVACY - Redact any element with a data-private attribute before rendering Include the capture, the console buffer and the redaction.
What you lose
- Screenshot capture from inside the browser, including the annotation layer
- Console errors and network failures captured automatically with the report
- Routing into issue trackers already built
If you would rather not build
- Sentry user feedback, if you already use it
- A form with a file upload, which is most of the value

80/100
Verdict yes at 80. The console buffer is the feature worth copying: it turns a useless report into a fixable one, and it is fifteen lines.
