Price and stock-check your whole BOM in one go.

Paste a parts list or drop a CSV/Excel export from KiCad, Altium or Eagle. Bomrun checks every line live across Mouser, DigiKey, Farnell and TME, flags end-of-life parts, and works out the cheapest way to split the order. Building a robot? Motors, sensors, connectors and cables are checked too, and mechanical or custom parts get quick links to RS, Misumi, McMaster and AliExpress.

Shipping thresholds used by the split optimiser
DistributorShippingFree over

Free for up to 20 lines per run. No account needed. Prices come straight from the distributors' own APIs; we never store your BOM in v1.

Order-split optimiser

Cheapest per line isn't cheapest overall once shipping and minimum orders count. Bomrun compares one-distributor orders against the best split and shows the real difference.

EOL and NRND flags

Every line carries its lifecycle status so you find the obsolete part before the purchasing department does.

UK and EU pricing

Prices converted to GBP or EUR, VAT added if you want it, so the number on screen is the number on the invoice.

Coming next

Saved BOMs with price and stock alerts, alternates for out-of-stock parts, and a KiCad plugin. Paid plans from £8/month; the free tier stays free.

BOM price checker – common questions

How do I compare BOM prices across Mouser, DigiKey, Farnell and TME?

Paste your parts list or upload the CSV/Excel BOM exported from KiCad, Altium or Eagle. Bomrun queries each distributor live and shows price, stock and MOQ for every line side by side.

Is Bomrun free?

Yes. Checking a BOM is free, with no account needed, and your BOM is not stored.

Can I check a KiCad BOM?

Yes. Export the BOM from KiCad as CSV and drop it in; manufacturer part number and quantity columns are detected automatically.

Does it find the cheapest way to split an order?

Yes. Bomrun compares buying everything from one distributor against the cheapest split once shipping and minimum order values are counted.

Does Bomrun flag obsolete or end-of-life parts?

Every line shows its lifecycle status, so EOL and NRND parts are flagged before you order.

Can I price robotics BOMs with motors and mechanical parts?

Electromechanical parts such as motors, sensors, connectors and cables are priced from the distributors, and mechanical or custom parts get quick search links to RS, Misumi, McMaster and AliExpress.
