While most of Thread is licensed under the AGPL 3.0, there are some exceptions:

• Some components were forked from Ast-Grep and are licensed under the AGPL 3.0 or later AND the MIT license. Our changes are AGPL; the original code is MIT. See VENDORED.md for details.
• Unless otherwise noted, documentation and configuration files are licensed under either the MIT license or the Apache License 2.0, your choice. This includes the README.md, CONTRIBUTORS_LICENSE_AGREEMENT.md, and other similar files. This allows for more flexibility in how these files can be used and shared.

We love contributions of any kind! By contributing to Thread, you agree to our Contributor License Agreement (CLA). This agreement ensures that we can continue to develop and maintain Thread while giving you credit for your contributions.

If you're in doubt, look at the top of the file, or look for a .license file with the same name as the file (like Cargo.lock.license). We follow the Reuse Specification for license information in our codebase, which means every single file should have license information. We also keep a Software Bill of Materials (SBOM) in the repository root: sbom.spdx. This file lists all the licenses of the files in the repository, and is generated automatically by our build system.
