Hi, I’ve uploaded a tool I created to GitHub for searching electronic component prices across some of the major marketplaces (currently Mouser, DigiKey, Farnell, and TME).

It’s a Python program with a pretty simple interface that uses the APIs of these distributors to fetch prices for any components you search. Essentially, you enter the part number and the desired quantity, and the tool queries the APIs of different stores to give you real-time info on pricing, stock, and availability.

In addition, it has a feature that generates an optimized shopping list in .xlsx format, helping you figure out which store to buy each component from to minimize costs. You can configure which markets to query and input your own API keys for each one.

I know there are some alternatives out there, but I find it really convenient to have something like this for myself, and the best part is that it relies on the official APIs of each distributor. Plus, since it’s all local, you have full control over your data.

I’d love to hear your thoughts on it, and if you think there’s something I could improve or add. Any feedback is welcome!

Thanks, and I hope it’s helpful! 🙌
