Fully open source: both the guardrails platform and the safety model are Apache-2.0 and self-hostable, including on-prem deployment. The repository has since become the monorepo for the OpenGuardrails (OGR) specification and its reference implementations, carrying the Python and JavaScript SDKs and the integrations alongside it - a shift in what the product is, though the licence, the public source and the ungated core are all unchanged.

  Repo metadata records license spdxId - Apache-2.0 and the README closes 'License. Apache-2.0'. The monorepo holds specification/ and schema/, packages/python and packages/javascript, integrations/, benchmarks/ and examples/, and the development section builds and tests the whole thing locally. The project describes itself as foundation-governed and neutral; there is no paid tier, enterprise directory or license key on the page.
