Fluidd is one of the two web interfaces most Klipper owners reach for (Mainsail is the other), and it's genuinely excellent: a fast, lightweight, fully local dashboard for a Klipper printer, built on the Moonraker API. If OctoPrint is the classic interface for Marlin machines, Fluidd is one of its Klipper counterparts, and a very well-made one.
SimplyPrint isn't a rival to that, and we don't pretend to be. We connect to Klipper printers through Moonraker's built-in [simplyprint] component, with no plugin to install, and we run happily alongside Fluidd (Moonraker allows several clients at once), so your Fluidd UI keeps working exactly as it does now. The honest difference is simple: Fluidd is built to run one Klipper printer beautifully. When one printer becomes a fleet, a classroom or a farm, that's the job SimplyPrint was built for.
Fluidd is free, open-source and fully local, and it's one of the best hands-on web interfaces for a single Klipper printer. If you run one (or a few) Klipper machines, love full local control, and don't need to reach them from outside your network, Fluidd is a brilliant choice, and you can keep it.
SimplyPrint is the layer above that, for when one printer becomes many. Instead of switching between printers one at a time, you get your whole fleet in one dashboard, reachable from any device, with an auto-assigning print queue and continuous printing (AutoPrint), AI failure detection and bed-check, built-in filament inventory and maintenance, central users, roles and SSO, and a schools plan. It runs Klipper (via Moonraker), Bambu Lab, Prusa, Marlin and Duet machines side by side, and it connects through Moonraker's built-in component, so it sits happily next to Fluidd. Fluidd for one Klipper printer; SimplyPrint for a fleet, a classroom or a farm.
Fluidd connects to one Klipper printer at a time. You can register several and switch between them, but it reloads onto a single printer each time - there's no screen that runs the whole fleet together. SimplyPrint was built for the opposite.
Fluidd is a local interface for a Klipper printer. Reaching it from outside your network, and running printers that aren't Klipper, is where the two part ways.
[simplyprint] component - nothing to install, and because Moonraker allows several clients, your Fluidd keeps working untouched.We mean this: for a lot of Klipper owners, Fluidd is the right answer, and SimplyPrint can't match it on these. Credit where it's due.
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 Fluidd as well!

[simplyprint] component (no plugin to install), and because Moonraker allows multiple clients, your Fluidd keeps working exactly as before. Most people who switch to SimplyPrint do so because they've outgrown a single-printer interface and want their whole fleet, remote access, a queue and automation - not because anything's wrong with Fluidd.[simplyprint] to your Moonraker config.We made SimplyPrint due to the fact, that nothing else on the market quite fit our needs. We wanted a platform that was easy to use, but still had all the features we needed. We wanted a feature-rich platform, intuitive and easy to use, with a great user experience and actual innovation within the 3D print management software space.
In summary, we - humble and unbiased as we are 😉 - believe that the SimplyPrint platform is a great Fluidd alternative!
