For anyone who debugs hardware

Any sufficiently good tool looks like magic from the outside.

Scryglass puts every log line, bus transaction, GPIO edge and microamp from your device under test on one timeline — instead of five windows and a wall clock.

MCPBuilt-in MCP server. Point any MCP client at it — running a cloud or local model — and it can drive the bench, read the traces and write up what it found.

Scryglass dashboard: a current trace with a recipe annotation, visible window statistics, a UART log, power and GPIO controls, and the engineer's own notes
THE VIEWER IS FREE, FOREVER

Send anyone a session. They can open it.

A colleague, a contract manufacturer, the vendor whose chip you think is at fault — they download Scryglass, open your file, and see the same timeline you saw. No licence, no payment, no expiry.
