Circuit Sherpa queries DigiKey and Mouser — live — and ranks every offer by price and stock. Paste your BOM and get the full build cost, with live stock and MOQ warnings on every line, in seconds. No more tab-hopping between distributor sites.
Free plan · 10 searches a day · No credit card
Search, compare, price the build, and watch the market — without leaving one tab.
Type an MPN once. Circuit Sherpa hits DigiKey and Mouser in parallel and ranks every offer — the best price is always at the top, not buried in tab #4.
Drop in a CSV — MPN and quantity is all it takes. Every line gets priced at the price break for its quantity, totals roll up instantly, and each line shows live stock and warns when your quantity is under the distributor's MOQ.
Prices and stock come straight from distributor APIs at search time — not stale scrapes. Circuit Sherpa also tracks price history per part, so you can see where a price is heading, not just where it is.
Set a target price on any part. Circuit Sherpa checks daily and emails you the moment an offer crosses your line. Stop keeping a mental list of parts to re-quote.
Paste your BOM as CSV — MPN and quantity is all it needs. Circuit Sherpa prices every line against live distributor offers, picks the best price per part, totals the build, and shows the live stock count and any MOQ warning on every line, so a thin part is visible before it becomes a schedule slip. Export the priced BOM back to CSV when you're done.
