Licensing

Nest is open source under a Limited AGPL-3.0 license.

The REST API resolves its license tier from the `https://nest.penguintech.io/tier` JWT claim (`free` or `pro`), issued by the auth service — never from a value supplied by the client outside the token.

Free tier is limited to 5 DataResources per tenant; the API returns an error directing the tenant to upgrade once the limit is reached.

Enterprise features require a LICENSE_KEY from license.penguintech.io, set as the LICENSE_KEY environment variable on nest-api. Without a license key, Nest runs in unlicensed mode; which specific capabilities that gates is resolved by the centralized PenguinTech License Server, not documented per-feature in the Nest repository.

Feature flags default off until explicitly validated against the license server, with graceful degradation to the last-known cached value if the license server is unreachable.
