Autodesk Fusion Alternatives 2026: 5 Options, 4 Free
Autodesk Fusion alternatives: FreeCAD, Onshape, SolveSpace, OpenSCAD and 1 more. Prices and licenses checked October 25, 2026.

Verdict:Leave Fusion if the free personal-use license no longer fits. Autodesk's personal-use page, as quoted in search, limits it to hobbyists earning under $1,000 USD a year from home-based non-commercial projects, with 10 active editable documents. If you sell parts, run a small shop or hit that document cap, you are in paid territory. Check Autodesk's pricing page for the current commercial price. FreeCAD is the straightforward replacement for mechanical parts: no cap, no license term, GPL code, but a rougher interface and weaker CAM. Onshape is the closest browser-based experience and is free for non-commercial work with public documents. SolveSpace and OpenSCAD cover simple parts with tiny installs. SolidWorks is the pro-grade paid alternative, at several times Fusion's price, and only worth it if employers or customers need native files. The trade-off is CAM: Fusion bundles toolpaths for CNC, and none of the free tools match that in one app, so a CNC user might pair FreeCAD with a separate CAM package. If your hobby work stays under the revenue limit, staying on Fusion personal is fine. Leave when the license starts to constrain you or when you want files you can own forever.

Good fit if
- You sell parts and need no usage cap (FreeCAD is the pick)
- You want browser CAD and version control (Onshape is the pick)
- You want a tiny offline CAD tool (SolveSpace is the pick)
- You need pro-level assemblies and can pay (SOLIDWORKS is the pick)
Not ideal if
- You rely on Autodesk Fusion features or integrations that these tools do not replicate
Autodesk Fusion today: Free (Personal-use license for hobbyists earning under $1,000 USD a year from home-based non-commercial projects; limited to 10 active editable documents, per Autodesk's personal-use page as quoted in search) (Autodesk Fusion pricing, checked 2026-10-23).
Why people look for Autodesk Fusion alternatives
Autodesk's personal-use licence is limited to hobbyists earning under $1,000 a year from home-based, non-commercial projects, and caps you at 10 active editable documents, per Autodesk's personal-use page as quoted in search. Anyone selling parts, doing client work or running a small business needs the paid commercial subscription, so the free route disappears at the moment a hobby earns money.
FreeCAD
Compared with Autodesk Fusion: Free and open source with no revenue cap or document limit. It has weaker CAM and a rougher interface than Fusion, but nothing expires and nothing is capped.
Price: Free (Free, no sign-up) (FreeCAD pricing, checked 2026-10-22).
Platforms and license: Windows, macOS, Linux. LGPL-2.1 (open source).
Project activity: 34.9k GitHub stars · latest release 1.1.4 (Sep 28, 2026) · last commit Oct 27, 2026
Best for: No-limit free parametric CAD.
Worth knowing: Mainly parametric 3D; 2D drafting is not its strength.
Onshape
Compared with Autodesk Fusion: Browser-based parametric CAD with a free non-commercial tier. Documents are public on that plan, and it has no built-in CAM like Fusion, but the version control is strong.
Price: Free (Free plan for non-commercial use; all documents are public); paid from $1500 per user/year, Standard, billed annually (Onshape pricing, checked 2026-10-22).
Platforms and license: Web. Proprietary.
Best for: Cloud CAD with version history.
Worth knowing: Cloud 3D parametric CAD, not a DWG drafting tool.
SolveSpace
Compared with Autodesk Fusion: Free GPLv3 parametric CAD. Lighter than Fusion with no cloud, CAM or simulation, but it keeps working with no license term to renew.
Price: Free (Free and open source) (SolveSpace pricing, checked 2026-10-23).
Platforms and license: Windows, macOS, Linux. GPL-3.0-or-later (open source).
Project activity: 4.2k GitHub stars · latest release v3.3 (Oct 21, 2026) · last commit Oct 27, 2026
Best for: Small offline parametric CAD.
OpenSCAD
Compared with Autodesk Fusion: Free, GPL-licensed and driven by scripts. No sketch UI and no CAM like Fusion, but useful for parametric parts.
Price: Free (Free software; no paid tier) (OpenSCAD pricing, checked 2026-10-23).
Platforms and license: Windows, macOS, Linux. GPL-2.0 (open source).
Project activity: 10.5k GitHub stars · latest release openscad-2021.01 (Feb 7, 2021) · last commit Oct 27, 2026
Best for: Code-defined parts.
Worth knowing: Script-based solid modeler: you describe parts in code, there is no drag-to-sketch interface. License from an archived copy of openscad.org; other listings say GPL-2.0-or-later.
SOLIDWORKS
Compared with Autodesk Fusion: Paid industry standard on Windows, listed at $2,820 a year for Standard in its FAQ. It has deeper assemblies and drawings than Fusion, but costs far more and lacks Fusion's integrated cloud CAM.
Price: Paid from $2820 per year (Standard, single-user subscription, excluding taxes) (SOLIDWORKS pricing, checked 2026-10-23).
Platforms and license: Windows. Proprietary.
Best for: Professional mechanical design on Windows.

Shapr3D
Compared with Autodesk Fusion: Basic is free but limited to 2 projects with low-resolution STL and 3MF export; Pro is $299 per editor seat a year. Touch-friendly on iPad, Mac and Windows, with simpler modeling and no Fusion-style CAM.
Price: Free (Basic plan: up to 2 projects, 3 generative renders a day, low-resolution STL and 3MF export only, no technical drawings); paid from $299 per Editor seat/year, billed annually (Pro, excluding VAT) (Shapr3D pricing, checked 2026-10-25).
SketchUp
Compared with Autodesk Fusion: Paid Go plan is $10.75 per user a month billed annually. Easier for woodworking and architecture-style models, but not the parametric, CAM-linked engineering workflow that Fusion offers.
Price: Paid from $10.75 per user/month, billed annually (Go plan) (SketchUp pricing, checked 2026-10-23).
Which one to pick
- You sell parts and need no usage cap: FreeCAD
