This summary is not legal advice. The LICENSE file is what applies.

The license#

The project is licensed under the Apache License, Version 2.0, subject to the Commons Clause License Condition v1.0. The SPDX expression on every source file is:

Apache-2.0 AND LicenseRef-Commons-Clause-1.0

The Commons Clause removes from the Apache grant the right to "Sell" the software: to provide to third parties, for a fee or other consideration, a product or service whose value derives entirely or substantially from its functionality. Everything else in Apache-2.0 applies, including its explicit patent grant.

Note

Because of the Commons Clause, One Connect is source-available, not open source under the OSI definition. The code is public and you can use and change it, but the selling restriction is not something an OSI-approved license allows.

Third-party software#

THIRD_PARTY_NOTICES.md lists every runtime dependency, JavaScript and native Rust, with its license. It is generated and checked in CI (pnpm license:check) against the allowlist in license-policy.json.
Some native dependencies use MPL-2.0. The engine bundle includes those crates' unchanged sources and notices, and the inventory links their exact upstream versions.
GPL, AGPL, SSPL and unknown runtime licenses are kept out of the build.
The bundled local models (Qwen3, Apache-2.0) and llama-server (llama.cpp, MIT) keep their own licenses.
Pinned design skills keep their upstream licenses (MIT and Apache-2.0) and notices.
OpenCode, Docker, Graphify, Ollama, Tailscale and every vendor agent CLI are installed by you and are not redistributed.
