Circuit Sherpa queries DigiKey, Mouser, Arrow, Avnet, TTI, and more — live — and ranks every offer by price and stock. Paste your BOM and get the full build cost, with shortage risks flagged, in seconds. No more six-tab price checks.
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, Mouser, and the Nexar network (Arrow, Avnet, TTI, and more) 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 best live offer, totals roll up instantly, and low-stock parts are flagged before they stall your build.
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 flags shortages while they're still a footnote instead of a schedule slip. Export the priced BOM back to CSV when you're done.

You can — that's the six-tab workflow this replaces. Each distributor only shows its own stock and its own price. Circuit Sherpa runs the comparison for you and links you straight to the winning distributor to buy. No markup, no middleman, no inventory of ours in between.
Offers are pulled live from distributor APIs when you search — price, stock, and packaging as the distributor reports it right now. Search results are cached briefly for speed, and every lookup feeds the per-part price history.
It stays yours. BOM history is kept for 90 days on paid plans so you can re-price a build, and you can export or delete it whenever you want. We don't sell data and we don't process purchases — buy links go directly to the distributor.
