¿Buscas alternativas a Fluidd?

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.

En resumen

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.

One Klipper printer, beautifully. A fleet needs more.

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.

Managing the fleet
SimplyPrint
Every printer (Klipper, Bambu, Prusa, Marlin, Duet) lives in one dashboard, monitored and controlled together, grouped however you like.
Fluidd
One printer at a time. Fluidd's "multiple printers" feature lets you add each printer's Moonraker address and switch the active one, but you operate a single printer per session, and the printer list lives in that browser's local storage - there's no unified fleet view.
Keeping it printing
SimplyPrint
A queue auto-assigns and auto-starts each job on the next free, suitable printer, and AutoPrint keeps the fleet running lights-out.
Fluidd
The only queue is Moonraker's per-printer FIFO job queue, scoped to that one machine. There's no cross-printer queue, no auto job-assignment and no fleet automation - coordinating printers means external scripts against each one's API.
People & classrooms
SimplyPrint
One account works across the whole fleet, with central roles and granular permissions, SSO, and a dedicated schools plan (classes, teachers, students, approval queues).
Fluidd
No account system of its own - it leans on Moonraker's optional login. You can have a couple of logins, but every user gets the same full access; there are no roles, permission groups, SSO or education features.
For one Klipper printer, Fluidd's single-printer model is exactly right. For many, you're switching between separate dashboards with nothing tying them together - and stitching a fleet together is the whole reason SimplyPrint exists.

Reach it from anywhere, and run more than Klipper

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.

Remote access
SimplyPrint
Cloud-native: reach every printer from any browser, plus native iOS and Android apps, with nothing to expose and no port-forwarding.
Fluidd
No built-in remote access - Fluidd talks to Moonraker on your LAN, and the Klipper world's guidance is not to open Fluidd/Moonraker ports to the internet. Remote means adding a VPN, a relay (OctoEverywhere, Obico) or a secured reverse proxy yourself.
Which printers
SimplyPrint
Klipper (via Moonraker), Bambu Lab, Prusa, Marlin and Duet, plus OctoPrint-connected machines, all in one fleet.
Fluidd
Klipper only. Fluidd needs Klipper firmware + Moonraker; it doesn't drive generic Marlin-over-serial printers or Bambu Lab machines.
It runs alongside Fluidd
SimplyPrint
SimplyPrint connects through Moonraker's built-in [simplyprint] component - nothing to install, and because Moonraker allows several clients, your Fluidd keeps working untouched.
Fluidd
Fluidd keeps doing exactly what it's great at on the local network; SimplyPrint just adds the cloud, the fleet view and the automation on top.
Fluidd gives you total local control of a Klipper printer that's in the room with you. SimplyPrint gives you secure access to your whole mixed fleet from anywhere - and it runs next to Fluidd, not instead of it.

Where Fluidd is the better pick (and how we work together)

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.

A single Klipper printer
SimplyPrint
Built for one or many printers, but it's a managed cloud platform, not a local UI you own and tweak line by line.
Fluidd
For one Klipper machine, one of the nicest hands-on UIs there is: a fast, lightweight layout with config editing, G-code preview, bed-mesh visualisation, macros and themes - fully under your control.
Free, local & open-source
SimplyPrint
A cloud platform (EU/US data centres, GDPR-compliant). On-prem is an enterprise, contact-based option.
Fluidd
Free and open-source (GPLv3), running entirely on your own hardware with no cloud - the right call for offline, privacy-first or strict-IT setups, and for people who want to own the whole stack.
We're on the same side
SimplyPrint
We connect through Moonraker's built-in component and run alongside Fluidd, rather than replacing it - your local UI is untouched.
Fluidd
Fluidd keeps being the lightweight local Klipper UI it's great at; we'd genuinely encourage you to support the project too.
If you run a single Klipper printer, want to stay fully local, or love a lightweight hands-on UI, Fluidd is genuinely the better tool - keep it. When one printer becomes a fleet, a classroom or a farm, that's where SimplyPrint takes over, sitting right alongside Fluidd via Moonraker.

Comparativa entre Fluidd y SimplyPrint

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!

Ventajas de usar Fluidd

Fluidd has real, lasting strengths, and they're worth being honest about:

  • Free & open-source: GPLv3, self-hosted on your own hardware - you own the whole stack, no subscription and no cloud required.
  • A lightweight, polished Klipper UI: fast and responsive, with config editing, G-code preview, bed-mesh visualisation, macros and themes.
  • Easy install: set up with KIAUH (the Klipper Installation And Update Helper), which installs Klipper, Moonraker and Fluidd together.
  • Print history & Spoolman: shows per-printer print history and statistics (via Moonraker) and integrates Spoolman for filament-spool inventory.
  • Installable PWA & big community: runs as an add-to-home-screen web app, with a large, active Klipper community behind it.

Contras de usar Fluidd

Where Fluidd runs into a ceiling once you're past a single printer:

  • One printer at a time: you add and switch between printers (the list lives in your browser's local storage), with no unified fleet dashboard and no cross-printer queue, auto-assignment or automation.
  • Klipper only: needs Klipper firmware + Moonraker; it doesn't run generic Marlin-over-serial printers or Bambu Lab machines.
  • No built-in remote access: local-only by design, and the guidance is not to expose it to the internet, so remote use means a VPN, relay or reverse proxy.
  • No roles or SSO: it relies on Moonraker's optional login, which has no permission groups, roles, SSO or schools/education features.
  • No plugin system, slicer or AI: you extend it with Klipper macros and themes (no OctoPrint-style plugins), slice in a desktop slicer, and AI failure detection comes from a separate service like Obico.

Fluidd vs. SimplyPrint: preguntas frecuentes

Is SimplyPrint a replacement for Fluidd?

Not exactly - it's a different job, and the two work together. Fluidd is a local web UI for a single Klipper printer. SimplyPrint connects to your Klipper printer through Moonraker's built-in [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.

Can I use Fluidd and SimplyPrint at the same time?

Yes. SimplyPrint connects via Moonraker, which supports several clients at once, so you can keep Fluidd on your local network and add SimplyPrint's cloud on top - your Klipper config and Fluidd UI aren't modified. You just add [simplyprint] to your Moonraker config.

Is Fluidd or SimplyPrint better for multiple printers or a print farm?

For a single Klipper printer, Fluidd is excellent. For multiple printers it's a switcher: you add each printer's Moonraker address and view them one at a time, with no unified dashboard, cross-printer queue or automation. SimplyPrint is built for fleets - every printer in one dashboard, an auto-assigning queue, continuous printing with AutoPrint, AI failure detection, and filament and maintenance tracking across the whole farm, on Klipper and other brands together.

Does Fluidd support Bambu Lab or non-Klipper printers?

No. Fluidd is a Klipper interface - it needs Klipper firmware and Moonraker, so it doesn't drive generic Marlin-over-serial printers or Bambu Lab machines. SimplyPrint runs Klipper printers (via Moonraker) alongside Bambu Lab, Prusa, Marlin, Duet and OctoPrint-connected machines in one fleet.

Does Fluidd have remote access?

Not built in. Fluidd talks to Moonraker on your local network, and the guidance is not to open Fluidd/Moonraker to the internet, so remote access means adding a VPN, a relay (such as OctoEverywhere or Obico) or a secured reverse proxy yourself. SimplyPrint is cloud-native: you reach every printer securely from any browser, plus native iOS and Android apps, with nothing to expose.

Fluidd or Mainsail - which does SimplyPrint work with?

Both. Fluidd and Mainsail are the two most popular Klipper web interfaces, and they're both Moonraker frontends. SimplyPrint connects through Moonraker itself, so it works the same whether you run Fluidd, Mainsail, both, or neither - and it runs alongside them.

Is Fluidd free?

Yes - Fluidd is free and open-source (GPLv3), built by the fluidd-core team (creator Craig Bassett, "cadriel") and funded by community donations. SimplyPrint has a free tier too (2 printers, every feature) and paid plans as you scale, and it connects to your Klipper printer through Moonraker, so you can run both side by side. If you rely on Fluidd, do consider supporting the project.

Is Fluidd good for a print farm or classroom?

Fluidd is a single-printer interface, so a farm or classroom means opening a separate dashboard per machine with nothing tying them together (the printer list even lives in each browser's local storage). There's no fleet view, no cross-printer queue, no auto job-assignment and no central users, roles or schools features. SimplyPrint was built for exactly that: every printer in one dashboard, an auto-assigning queue with continuous AutoPrint, AI failure detection, filament and maintenance tracking, central roles and SSO, and a dedicated schools plan, all running alongside your Fluidd via Moonraker.

Does Fluidd have AI failure detection or continuous printing?

No. Fluidd has no built-in AI failure detection (people add a separate service like Obico) and no continuous, lights-out printing, because it drives one printer at a time. SimplyPrint includes AI failure detection and AI bed-check, plus AutoPrint for hands-off continuous printing across the whole fleet, on top of the same Klipper printers Fluidd already runs.

Conclusion
Why SimplyPrint is the Top Fluidd Alternative
