Open source
Free software, not a free tier
Promenade is developed in the open, with its source published under an open-source license. There's no paid tier of the core application, no feature gated behind a subscription, and no telemetry phoning home by default.
License
Promenade's source is published under an open-source license. The exact license text lives in the repository's LICENSE file, which is the authoritative reference — check it before relying on specific terms (redistribution, modification, or running a modified version as a network service) for your use case.
Self-hosting
Because Promenade is a static, client-side application with no required server component, self-hosting means serving the built static output from any web server or object storage you control — there's no backend to deploy alongside it for the core application to work. See the architecture page for what does and doesn't run server-side.
What "open source" doesn't include here
Promenade Compute — the optional backend for workloads too large for a browser tab — is a separate, still-evolving component; see the ecosystem overview. Its licensing and distribution will be documented here once it ships. Using Promenade in the browser never requires it.
