Spoolman is a free, open-source, self-hosted filament inventory: a tidy database of your spools that you run on your own server. It's genuinely good software, and if you live in Klipper and Moonraker and want to own your data, it's a sensible pick.
But Spoolman is a database, not a tracker. It doesn't connect to your printers; it waits for other software to tell it what you used. SimplyPrint's filament manager works the other way around: it's connected to your printers, reads the G-code of every print, and keeps each spool accurate on its own, with no plugins, no scale, and no server for you to run. Here's a fair, side-by-side look, first purely as a filament manager, then as the whole platform.
Automatic usage tracking, NFC across every standard, Bambu & Creality AMS auto-import, direct Dymo & Zebra label printing, drying, storage locations, a mobile app and the Open Filament Database. See it all, with screenshots, on one page.

Compare Spoolman vs SimplyPrint:
Spoolman is a free, MIT-licensed, self-hosted spool database, a great fit if you run Klipper/Moonraker, want to own your data, and don't mind wiring up a plugin to feed it usage. It doesn't connect to printers itself.
SimplyPrint is a connected filament manager: it reads the G-code of every print on your printer and deducts filament automatically, with no plugins, no scale and no server to run, plus native NFC, Bambu and Creality AMS auto-import, direct Dymo and Zebra label printing, and the open, MIT-licensed Open Filament Database (151 brands and growing). And the filament manager is free on every plan. If you want tracking that just happens across any printer brand, that's SimplyPrint; if self-hosting a database you control is the point, that's Spoolman.
Comparing purely as a filament manager, the deep, head-to-head view.
This is the heart of it. Spoolman is a database that other software has to feed; it doesn't talk to your printers. SimplyPrint is connected to them, so your inventory stays right on its own.
[spoolman] component or the OctoPrint-Spoolman plugin and set the active spool yourself, and only for Klipper or OctoPrint-hosted printers.Credit where it's due: Spoolman's filament data is genuinely open. So is ours. The difference is reach, how you contribute, and whether the data is wired into tracking.
Spoolman is a well-made tool, and for some setups it's the right call. Credit where it's due:
Spoolman does one job, filament inventory, and self-hosts it well. SimplyPrint includes that same filament manager and surrounds it with the rest of a print operation: a print queue, a full cloud slicer, AI failure and bed detection, a maintenance system, teams and permissions, mobile apps and more, in one hosted platform that's free to start. In the table below, Spoolman's column is filament; ours is the whole platform.

Nothing is black-and-white, and there are always pros and cons to consider when choosing a 3D printing cloud solution!
And we're not here to simply tell you, that SimplyPrint is the best - we want you to make an informed decision, and of course there are pros of using Spoolman as well!

[spoolman] component or the OctoPrint-Spoolman plugin and set the active spool, and only for Klipper or OctoPrint-hosted printers. SimplyPrint reads the G-code of every print on a connected printer and deducts usage automatically, with nothing to install.Nous avons créé SimplyPrint parce que rien d’autre sur le marché ne correspondait vraiment à nos besoins. Nous voulions une plateforme facile à utiliser, mais disposant de toutes les fonctionnalités dont nous avions besoin. Nous voulions une plateforme riche en fonctionnalités, intuitive et simple d’utilisation, offrant une excellente expérience utilisateur et une véritable innovation dans le domaine des logiciels de gestion de l’impression 3D.
En résumé, nous pensons, humbles et impartiaux comme nous le sommes 😉, que la plateforme SimplyPrint est une excellente alternative à Spoolman !
