What BugTape does
BugTape does not record every visit. It keeps a short buffer and sends it with a supported error or a user report. Repeats of the same failure become one issue. An authorized agent reads that issue over MCP after one sign-in. DOM replay is rebuilt from events; it is not a screen video. Server SDKs (Node.js, Python) add route, service and release so a fix anchors to what shipped.
