Best print farm software for Klipper printers

The answer depends on the bottleneck: PrintStash for the file library and fleet queue, O.D.I.N. or SimplyPrint for monitoring, print-farm-manager for dispatch.

There is no single best, because the tools in this space own different jobs. If the farm’s problem is files, meaning nobody can tell which of six slices of the same bracket printed well or get that file onto the right machine without a USB stick, the answer is a library with a fleet queue, and that is PrintStash. If the problem is operations, meaning live telemetry, a camera wall, and software that notices a failed print before the operator does, the answer is a farm dashboard such as O.D.I.N. or a cloud platform such as SimplyPrint. Naming the bottleneck first makes the comparison short.

The three jobs

A Klipper farm has one property that makes all of this easier: every machine speaks Moonraker, so anything with an API client can manage the whole fleet without touching printer configuration. That still leaves three jobs for the software to own.

  1. File and G-code management: where the STLs, 3MFs, and slices live, and whether you can find the revision that actually printed well.
  2. Dispatch and queueing: routing jobs to machines, reordering, cancelling, retrying.
  3. Monitoring and operations: live status, cameras, failure detection, cost and order tracking.

Most farms eventually want all three, but the tool that owns monitoring is not automatically the right one when files are the real pain, and the reverse holds too. For a survey of the whole self-hosted field organized by these layers, including FDM Monster and AutoFarm3D, see self-hosted print farm management for Klipper printers. This post is the shorter version: which tool to start with, given what hurts.

When PrintStash is the answer

PrintStash starts from the files. Every G-code file is a revision of its source model with parsed slicer metadata, and each revision carries an outcome: needs_test, known_good, failed, or archived. One revision per model can be marked recommended, so three months later there is one unambiguous answer at the top of the page. Since v0.11.0 the same vault feeds a fleet queue that dispatches over Moonraker with manual, default-printer, or least-busy routing, and queued jobs can be reordered, rerouted, cancelled, and retried. Soft-drain mode and maintenance windows take a machine out of rotation without unplugging it. Queueing and scheduling across a printer farm is the detailed version of that layer, including the /api/v1/fleet endpoints.

Moonraker is the stable provider and gets the full capability set, including measured filament consumption for real per-print cost. PrusaLink, OctoPrint, Bambu LAN, and Elegoo Centauri are beta with narrower capabilities, and the app disables actions a given printer cannot do. The compatibility matrix is the current list.

The whole application is free under AGPL-3.0, with no paid tier and no per-printer fee. The known-good workflow, which is the main reason to pick it, is covered in tracking known-good G-code revisions.

Checking the farm remotely splits along the same line. Dashboards sell the camera feed; PrintStash puts the queue, the revisions, and the cost history on the phone instead, over a VPN or a hardened proxy. Managing a print farm from a phone takes that case apart, including what it honestly cannot show.

When a farm dashboard is the answer

PrintStash has no cameras, no failure detection, and no order tracking. If those are what the farm is missing, look at these instead.

O.D.I.N. is a self-hosted farm platform that supports Klipper/Moonraker alongside Bambu MQTT, PrusaLink, and Elegoo SDCP. It streams cameras over WebRTC through go2rtc, accepting RTSP, USB, and IP sources, and runs its own failure detection (Vigil AI, on-device ONNX inference for spaghetti, detachment, and first-layer problems), then follows orders through products, invoicing, and inventory. Licensing is Business Source License 1.1, converting to Apache 2.0 on February 7, 2029, with self-hosting permitted and only hosting it for third parties restricted. Its documentation put the free community tier at five printers and one user, which a shared workshop passes quickly; tiers move, so check the current pricing page before planning around it.

SimplyPrint is the cloud option: 130+ printer brands, a shared queue with smart routing, one-click bulk start, AutoPrint, cross-brand AI failure detection, and workflow automation through Zapier and n8n. The trade is that someone else runs the infrastructure and the farm depends on their cloud. Some farms want exactly that; a self-hosting workshop usually rules it out.

print-farm-manager (MIT) is the minimal pick: a live fleet view, automated dispatch with an operator confirmation step before each follow-up job, CSV import that adds dozens of printers at once, and a TV dashboard mode, across Prusa, Bambu, Elegoo, Klipper, and OctoPrint. Its README carries a security note worth reading before you install it: the app “has no built-in authentication”, is “designed to run on a trusted local network only”, and warns that “your printer API keys are served to any client that can reach the server”. That is a defensible choice for one operator behind a router firewall and a real problem on any network where it is not.

Shortlist by bottleneck

The bottleneck Start with
G-code revisions nobody can tell apart, known-good hard to find PrintStash
Queueing trusted files across Klipper machines PrintStash
Camera wall, failure detection, order-to-ship O.D.I.N.
Managed cloud across many printer brands SimplyPrint
Minimal dispatch on a trusted LAN print-farm-manager

Questions that come up

Does PrintStash replace Mainsail or Fluidd?

No. It talks to the same Moonraker API and adds the library and queue on top, while Mainsail or Fluidd stays as the per-printer control surface for first layers, macros, and config edits. The same applies to the dashboards above: farm software sits beside the per-printer interface, not in place of it.

Is PrintStash actually free for a farm?

Yes. It is open source under AGPL-3.0 with no paid tier, no account, and no per-printer fee, so the cost is the hardware it runs on and your own time operating it. That time is real: remote access, backups, and upgrades are yours, which is the standing trade of every self-hosted tool here except SimplyPrint.

What hardware does PrintStash need?

Docker on amd64 or arm64, including a Raspberry Pi or NAS. Plan on 1 GB of RAM minimum and 2 GB to be comfortable, because thumbnailing large meshes is the expensive part.

Can I run PrintStash next to one of the dashboards?

Yes. Everything here talks to Moonraker over its API, so nothing claims exclusive control of a printer. Running PrintStash for the library and revisions while another tool owns cameras and monitoring is a reasonable split, at the cost of two systems to maintain.
