SolidCraft is open source under the MIT license or the Apache License 2.0, at your option. The README states that choice as "MIT OR Apache-2.0, at your option". The repository github.com/tangency-labs/solidcraft includes both LICENSE-MIT and LICENSE-APACHE, and Cargo.toml sets license to "MIT OR Apache-2.0". Repository details are on the SolidCraft GitHub page, and the project overview is on the home page.
What the MIT and Apache-2.0 files permit and require
You choose either the MIT license or Apache-2.0; each file states its own grant and its own conditions.
- LICENSE-MIT is the MIT License. Its copyright line reads Copyright (c) 2026 SolidCraft contributors. It grants any person who obtains a copy of the software and associated documentation permission to deal in the software without restriction.
- The rights it names are to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies, and to permit persons who receive the software to do the same.
- The MIT condition is that the copyright notice and the permission notice be included in all copies or substantial portions of the software.
- The software is provided "AS IS", without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose and noninfringement. Authors and copyright holders are not liable for claims, damages or other liability arising from the software or its use.
- LICENSE-APACHE is the Apache License, Version 2.0, January 2004. Section 2 grants a perpetual, worldwide, non-exclusive, no-charge, irrevocable copyright license to reproduce the work, prepare derivative works, publicly display, publicly perform, sublicense, and distribute the work and derivative works in source or object form.
- Section 3 grants a patent license to make, have made, use, offer to sell, sell, import and otherwise transfer the work, only for patent claims a contributor can license that are necessarily infringed by that contribution, alone or combined with the work. If you file patent litigation alleging that the work or a contribution is direct or contributory patent infringement, those patent licenses end on the filing date.
- Section 4 allows reproduction and distribution in any medium, with or without modifications, in source or object form, when four conditions are met. Recipients get a copy of the Apache license. Modified files carry prominent notices stating that you changed them. Derivative-work source keeps the copyright, patent, trademark and attribution notices that still apply. When the work includes a NOTICE file, derivative works include the relevant attribution notices from it.
- You may add your own copyright statement to your modifications and different license terms for those modifications, or for derivative works as a whole, while your use of the original work still meets the Apache conditions.
- Section 5 places an intentional contribution under the Apache license unless you state otherwise, and a separate agreement with the licensor still stands.
- Section 6 gives no permission to use the licensor's trade names, trademarks, service marks or product names, except reasonable and customary use when describing the origin of the work and reproducing the NOTICE file.
- Sections 7 and 8 provide the work "AS IS", without warranties or conditions of any kind, and limit contributor liability for damages.
- Section 9 allows a redistributor to offer support, warranty or indemnity, and to charge a fee for it, only on that redistributor's own behalf, and only if that redistributor indemnifies the contributors.
- Beside the two license files, the repository also has NOTICE and THIRD-PARTY-LICENSES.txt. The documentation says that by contributing you agree your contribution is licensed as MIT OR Apache-2.0.
What the official pages list about pricing
At the time of writing (October 2026), the official website, documentation and GitHub README list no pricing information.
- Those sources do not include a pricing page.
- Those sources do not include a pricing explanation.
- A comparison with another CAD tool is on SolidCraft vs Fusion 360. What the project says about its own scope is on the SolidCraft review.
Where to get SolidCraft
Official release installers and the browser build are the two distribution paths the project lists.
- Desktop installers are published with the official releases. The SolidCraft download page lists the Windows, macOS and Linux packages from those releases.
- The browser build is at solidcraft.io/app. The project describes that build as needing no install.
Why the GitHub sidebar shows Apache-2.0, and SolidCore
The README names both licenses; the sidebar names one, and the geometry kernel has its own license.
- GitHub's repository sidebar shows only Apache License 2.0, likely because GitHub recognizes only one license file. That reason is our inference. The README still says "MIT OR Apache-2.0, at your option", and both LICENSE-MIT and LICENSE-APACHE remain in the repository.
- The geometry kernel SolidCore is licensed Apache-2.0 on its own. The project describes SolidCore as a Rust port of SMLib, NVIDIA's open-source C++ geometry library, being developed for use in SolidCraft.
