Overview

AstroPrint brings file handling, slicing, and printer management into a cloud-connected workflow. Users can keep STL and G-code files in a cloud library, slice designs in a browser, and monitor prints or pause, resume, and cancel them remotely. Analytics track filament use, operating hours, and success rates, giving users a view beyond the status of a single active job.

Printers connect through AstroBox Touch, AstroBox Gateway, a self-built AstroBox, or the OctoPrint plugin. AstroPrint also offers an AI tool for generating printable models from text prompts. That breadth makes it more than a slicer, but the service’s practical fit depends on how many printers and users need access and how much cloud storage they require.

Key features

Cloud files, slicing, and model generation

The cloud library keeps STL and G-code files together, while browser-based slicing avoids making desktop software the only route from design to print. The dashboard’s text-prompt AI tool adds a way to generate printable models. These capabilities suit users who want cloud tools in the same service as printer management, rather than a slicing-only workflow.

Remote management and analytics

Computer and smartphone users can monitor prints and remotely pause, resume, or cancel jobs. Filament-use, printer-hours, and success-rate analytics can help makers and education teams keep track of usage across printers. The mobile app can search Thingiverse and start printing designs; live video streaming, however, requires a browser rather than the app.

Printer connections and compatibility

AstroPrint supports several connection routes, including AstroBox hardware and the OctoPrint plugin. Klipper is supported for slicing only, a meaningful limitation for users expecting the same printer-management support they get with other connections.

Pricing

AstroPrint uses a freemium model, with a free plan and paid service from $9.90/mo.

Plan	Price	What it includes
Basic	0.00 USD per free	2 printers, 1 user, and 1GB file storage
Premium	9.90 USD per month	First 5 printers included, then $5/printer after; 1 user and 10Gb file storage, with $1/addt'l 10GB
Business & Education	Custom pricing	Unlimited printers, users, and file storage

Basic is a sensible starting point for a casual user with no more than two printers and one account, but the 1GB storage cap constrains a growing file library. Premium raises the printer allowance to five and storage to 10Gb, but remains limited to one user; extra printers and storage add cost. It suits an individual managing a small fleet, not a team that needs shared access. Business & Education removes the listed printer, user, and storage limits and includes priority single point-of-contact phone support, making custom pricing the relevant route for larger organizations. Premium includes priority email support.

Platforms

AstroPrint supports Android, iOS, Linux, macOS, Windows, web, API, and self-hosted use. AstroPrint Desktop is compatible with Mac OS X, Windows, and Linux. The mobile app’s lack of real-time video streaming makes the browser the right choice when live viewing matters.

Who it's for

AstroPrint is best suited to makers who want remote printer control, cloud files, and slicing in one service, and to education users managing printers at a larger scale. Its free tier serves casual use, while the single-user paid plan is more appropriate for an individual than a collaborative workshop. Teams should weigh the custom-priced Business & Education tier against their need for unlimited users and printers.

Pros and cons

Pros

Combines cloud storage, browser slicing, remote controls, and print analytics, so users can manage several parts of the print workflow in one platform.
Offers multiple printer connection routes, including AstroBox options and an OctoPrint plugin.
The free tier allows two printers and one user, giving casual users a way to manage more than one printer without a subscription.
Business & Education provides unlimited printers, users, and storage, with priority phone support for a single point of contact.

Cons

Basic storage is capped at 1GB, while Premium charges more for extra storage and printers.
Premium still allows only one user, so shared team access means moving to custom-priced Business & Education.
Klipper support is limited to slicing, not the broader printer-management capabilities.
The mobile app cannot stream live video; users must switch to a browser for that.

Alternatives

For a broader directory of tools, browse 3D Printing Software.

Polar Cloud is another freemium cloud option; its free plan allows one printer, five print jobs per month, seven-day history, and 300 MB of storage, and accepts mesh files only with a 30 MB file limit. Choose it if those narrower free-tier limits suit your workflow.
PrusaSlicer is a free, open-source slicer based on the Slic3r project. Choose it when open-source slicing is the priority rather than AstroPrint’s combined printer-management platform.
SimplyPrint is a freemium option with a free plan for up to two printers and one user, plus one location, 15 cloud slices per month, and 12 AI Failure Detection hours per month. Consider it if those allowances and features match your needs.
Bambu Studio is free slicing software with an optional networking plugin and SD card printing without the plugin. Choose it when that slicing and printing setup is a better fit than AstroPrint’s broader management workflow.
KISSlicer offers a free plan limited to one selected extruder per print, even on multi-extruder printers. Consider it if that free-plan constraint works for your setup.
Lychee Slicer has a free Lite plan with limited Multi-Plate, ads on export, and Windows, macOS, and Linux support. It may suit users looking for a desktop slicer with those trade-offs.
OrcaSlicer is a free, open-source FDM printer slicer for Windows, macOS, and Linux. Choose it if a free desktop FDM slicer is what you need.
OctoPrint is a free alternative for printer management.

Verdict

AstroPrint is a strong fit for makers who want cloud files, browser slicing, remote controls, and print analytics in one printer-management service. Its free tier is useful for a small personal setup, but the one-user Premium plan and added charges for printers and storage make it less compelling for growing teams. Choose Business & Education for organization-scale access, or look elsewhere if you need Klipper management or live video in a mobile app.
