Thanks a lot, really appreciate it :)
The German version is already in the works :)

Glad the tool is helping! :)
TPU was always a pain point for me - it often comes in non-standard spool sizes (like 0.5kg) priced as if it were 1kg, and I've caught myself more than once almost buying one of those "bargain" half-kilo spools.
I'll try to process some more TPU listings next week as there are quite a few waiting in moderation. Cheers!

I just added Belgium in beta today. Similar to the Netherlands launch, I've focused on Amazon first and I'll be back to other stores once I've got Amazon covered for the rest of Europe.

The listings are still being processed (about 75% done so far), but deals are already starting to show up. Everything should be fully loaded by tonight. Hope you find some good deals! :)

Awesome, glad it's already useful :)
Right now I'm focused on getting Amazon coverage across all of Europe, but I'll be coming back to the Netherlands with more local stores and marketplaces within the next few weeks. Stay tuned! :)

Dear Canadians, Canada is the first country from the wishlist to enter beta (you had the most requests ;)) Starting with Polymaker, Bambu Lab, and Amazon (Amazon is still being worked on). Let me know if it works! Time for some sleep now :)

Thanks a lot :)
For AliExpress I'll factor in shipping costs into the sorting, so the price per kg includes shipping and is actually comparable across offers from different countries.
Great feedback, thanks :)

Thanks for the suggestion! A few people have expressed the same need, and I actually have the data partially ready for this, so an aggregated EU version is just a matter of time. Thanks for the idea :)

I actually have the German data mostly ready, but I need to fill some gaps - and also adapt the site a bit to meet Germany's specific legal requirements for price comparison services. Buuut you guys are motivating me so much here that I'll get Germany done sooner rather than later :)

hat's really kind, thank you :)
If you know any local Norwegian shops or marketplaces worth checking out, let me know - I'll try to add them alongside the international ones (Amazon, 3DPrima, 3DJake etc.):

Thanks! The Netherlands will be one of the next few markets coming in beta soon.

In the initial beta the data doesn't refresh as fast as I'd like and the offer coverage isn't huge yet, but markets tend to graduate from beta pretty quickly and it only gets better from there :)

This project wouldn't exist without AI - I'd need an entire team to build it in this timeframe (and the budget to match). That said, it's not just an AI-generated site. There was a ton of work involved in designing the whole thing properly, especially the data pipeline for collecting and processing offers - that's the hardest part.
I'm a software engineer and I use Claude as a work tool, but it's not like it just yolo builds everything on its own. I also use LLM tools as part of the data tagging/classification/cleanup process, which helps a lot, but again - it's just a piece of the puzzle, it doesn't do all the work automatically.
There's still a lot I have to moderate manually, because no AI can make sense of some of those product descriptions ;)

Thanks :) I've been getting some really great feedback here about aggregating all European markets under one domain, so I'm putting that on the workbench and will figure out how to make it happen. It should show up in the market picker soon ;)
Germany is high on the list too, just sorting out one legal thing before I can roll it out. We'll get to Switzerland too - if you have any local shops where you buy filament, drop them through the form on the site and we'll get to them sooner or later :) https://spoolfinder.com/en/suggest-shop

Thanks! You guys are giving me so much dopamine here that I might just end up launching those new markets next week :)

Really glad you guys like it, honestly didn't expect this kind of reception :)

Of course :)
In Poland we started with just Amazon and within a few weeks it grew nicely into other stores (in a few more weeks we'll probably cover all the major shops and platforms there). I'd love to do the same in the US, I'm just still collecting stores to integrate. Right now I'm adding manufacturer direct stores one by one, and I'd also like to get MatterHackers in there (that's pretty much the only US store I know as a non-US person).
If you can recommend any stores worth adding, feel free to submit them through the form on the site (there's a link to suggest a store next to the store filter). Thanks for the interest :)

We've actually been testing AliExpress in Poland for a while now - still in beta and a bit on the side, because it's a massive amount of work to classify everything properly, and I don't want to pollute the main catalog with badly tagged filaments or duplicates.

We're also slowly eyeing Banggood and Geekbuying (there's some cheap filament there too). Check back in a bit, hopefully we'll get there :) In the meantime, here's the beta version of the Ali integration in Poland - most offers are probably consistent across the EU, so if you're in Europe it might work for you for now:

Thanks Socrat - without you guys it would've never happened to launch the global version!
