RustDesk offers a solid, open-source alternative for remote desktop solutions and is available for commercial use under the AGPL-3.0 license, albeit with strict requirements.
The developers clearly state in the README that they do not support unethical or illegal use of the software. Misuse, such as unauthorized access or invasion of privacy, is expressly warned against. This is vital for businesses to consider when deploying this tool to avoid potential legal pitfalls.
If your project aligns with the AGPL-3.0 requirements and you're willing to share your modified code with the community, RustDesk could serve as a robust solution for your remote desktop needs. Just be prepared for the licensing obligations that come with using an AGPL-licensed product in a commercial environment.
