Footgun Database

Thermal issues, counterfeit warnings, undocumented errata, gotchas at scale. Sourced from engineers, not marketing.

Multi-Distributor Stock

Mouser, DigiKey, and more in one view. Real-time inventory and pricing without opening five browser tabs.

NRND/EOL flags, drop-in replacements, and second-source options. See it at design time, not when procurement panics.
