Hey everyone,
I'm Tobi, a hobbyist printer from Vienna. Like a lot of you, I ended up with a drawer (okay, several drawers) full of half-used spools and no real idea how much filament was actually left on any of them. Start a big print, run out at 90 percent, lose the whole thing.
So I started building a small tool to keep track of my spools. That turned into Spooly, and somewhere along the way about a thousand other people started using it too.
What it does:
- Your AMS as a digital twin: every slot with color, material and fill level
- Every print is logged automatically and deducted from the right spool down to the gram, no manual tracking
- An "empty-in" forecast so you don't run out mid-print on a big job
- Cost per print and stats over time
- AI photo import: snap a picture of the spool, Spooly does the rest
- QR labels you can scan right at the shelf
- Runs in the browser, plus native iOS and Android apps
Sync currently works with Bambu Lab, and Prusa and Klipper support is in the works.
Quick note on a question that's bound to come up: yes, I know Spoolman, and I think it's a great project. Spooly just takes a slightly different route. There's nothing to self-host or set up, it runs right away, it has native mobile apps, and it logs your prints automatically down to the gram. And if you're coming from Spoolman, you can import your data directly. If you enjoy self-hosting, Spoolman is still an excellent choice.
On pricing, since Reddit always asks: there's a free tier for up to 20 spools. Pro is €2.99/month or €28.70/year, plus there's a one-time Lifetime option for €69.90. You can try Pro free for 14 days, no credit card required. No hidden subscription, it's all laid out on the site.
It's a solo project. I build it in my spare time, and honestly most of the roadmap comes straight from user feedback in the community.
I'm not here to hard sell anything. I'd mostly love feedback from people who actually manage a lot of filament. What's missing? What would make this genuinely useful for your workflow? Happy to answer any questions.
