Licensing

Everything in this repository is licensed under the Apache License 2.0, with one exception: cloudpdf/server — the self-hostable CloudPDF server — is Fair Source, under the Fair Core License, Version 1.0, ALv2 Future License (FCL-1.0-ALv2).

Code	Where	License
EmbedPDF SDK (@embedpdf/*)	packages/	Apache-2.0
CloudPDF client libraries (@cloudpdf/engine, @cloudpdf/viewer*, @cloudpdf/sdk, …/contract)	cloudpdf/	Apache-2.0
CloudPDF server (@cloudpdf/server)	cloudpdf/server/	FCL-1.0-ALv2
Websites	website/, cloudpdf/website	Apache-2.0 code; content per their LICENSE
Examples & tooling	examples/, tooling/	Apache-2.0

The rule behind the line: libraries are Apache-2.0; the deployable server product is Fair Source. Client SDKs, contracts, engines, viewers, plugins — anything you link into your own software — carry no strings. The server is the product we sell, so it ships fair-source instead of proprietary.

What the FCL means for you

• Source-available, not free to run. The FCL lets you inspect, copy, and modify the source for a Permitted Purpose, subject to its terms, but it does not grant you a CloudPDF license. The server fails closed: running or self-hosting a current FCL-licensed release requires a valid CloudPDF license key, or a signed certificate for an air-gapped deployment.
• The license gate must remain intact. You may not move, change, disable, or circumvent the license-key functionality; enable protected functionality without a valid key; or remove protected functionality.
• No Competing Use. You may not use the server for a Competing Use as defined in the FCL, including offering a product or service that substitutes for CloudPDF or provides the same or substantially similar functionality.
• It becomes Apache-2.0 automatically. Each release converts to the Apache License 2.0 two years after it is made available — per release, so an old enough version is plain open source.

The licensor is CloudPDF LTD.

Website content

The websites' application code is Apache-2.0 like the rest of the repository; their content is zoned — see website/LICENSE and cloudpdf/website/LICENSE:

• documentation prose: CC-BY-4.0;
• code samples in the docs: MIT-0 (copy freely, no attribution needed);
• articles, blog posts, and brand assets: all rights reserved.

Trademarks

"EmbedPDF", "CloudPDF", the logos, and the design-system assets are brand property of CloudPDF LTD. Neither Apache-2.0 (§6) nor the FCL grants trademark rights.

Authority

For any package, the authoritative declaration is its own LICENSE file and the license field of its package.json. Directory placement decides nothing. (@cloudpdf/server's package.json reads SEE LICENSE IN LICENSE because FCL-1.0-ALv2 is not yet an SPDX identifier.)
