7 Spoolman Alternatives for Filament Tracking in 2026

Spoolman is the go-to answer to "how do I track filament spools" if you're running Klipper or OctoPrint: a free, open-source tool that keeps an exact gram count for every spool. But depending on what you actually need — not running your own server, automatic weighing, or costing an order instead of tracking a spool's remaining weight — a different tool might fit better. Here's the rundown.

What to look for

• Don't want to run your own server — you need tracking without Docker, updates, and backups.
• You need automatic weighing, not manually entering the spool weight when you load it.
• You need the business side — what a print actually cost and what to charge for it, not just what's left on the spool.

If that last point is your case, skip ahead to the 3D Print Pricing section for the short answer.

1. SimplyPrint

A cloud fleet-management platform with built-in filament tracking — no server to set up. A good fit if you want cloud fleet management for your printers in general, not a standalone spool tracker.

2. FilaMan

An ESP32-based scale plus NFC tags: it weighs the spool and writes the remaining amount to the tag, with integrations for Bambu Lab, Klipper, and OctoPrint. A fit for anyone who wants an actual scale in the loop instead of a firmware-based usage estimate.

3. FilaMeter

An open-source, self-hosted spool database in the same vein as Spoolman. Worth a look if you want to compare implementations or Spoolman's interface is missing a specific feature you need.

4. Spool Buddy / Spoolstock / FilaTrack

Lesser-known open-source spool trackers solving a similar problem — self-hosted databases of weight and history. Their communities and integrations are noticeably smaller than Spoolman's.

5. FilamentManager (OctoPrint plugin)

An OctoPrint-only plugin that predates Spoolman. A lighter-weight option if you're not planning to move to Klipper/Moonraker.

6. An Excel spreadsheet

Works fine for a single printer and a handful of spools. Once the number of spools or printers grows, manually updating it stops paying for the time it costs you.

7. 3D Print Pricing — order costing and pricing

If your actual question isn't "how much filament is left" but "what did this order cost me and what should I charge for it," none of the tools above answer that, Spoolman included — it's simply a different job. 3D Print Pricing treats filament as a business expense: purchase batches with a price tag, a single feed for stock in and stock out, and deductions tied to customer orders that immediately feed into order pricing in the calculator. It's cloud-based, no server required, and signing up takes under a minute.

Bottom line

If you're printing at home purely for yourself on Klipper, any spool tracker from options 1–6 will settle the question of grams. But if you print for customers even occasionally, every one of them eventually hits the same ceiling — costing and pricing the order. That's the part 3D Print Pricing covers.
