Licensing

Sirr is source-available under the Business Source License 1.1. Free for most use cases, with a commercial license for large-scale production deployments.

License Overview

Free	Up to 100 active secrets per instance
Free	All non-production use (dev, staging, CI)
Source available	Forks and modifications permitted
Converts to Apache 2.0	February 20, 2028
Commercial license	Required for >100 active secrets in production

What BSL 1.1 Means

The Business Source License 1.1 is a source-available license created by MariaDB. It grants you the right to read, modify, and redistribute the source code — with one restriction: production use beyond the specified limit requires a commercial license.

After a fixed date (the “change date”), the code automatically relicenses under Apache 2.0, making it fully open source with no restrictions. For Sirr, this date is February 20, 2028.

When You Need a License Key

Your production instance has more than 100 active secrets at any given time
The Sirr server returns 402 when you try to create a new secret — this means you've hit the free-tier limit

You do not need a license for:

Development, staging, or CI environments (any secret count)
Production instances with 100 or fewer active secrets
Personal or open source projects

Using a License Key

Pass the license key as an environment variable when starting the server:

SIRR_LICENSE_KEY=sirr_lic_... ./sirrd serve

Or in Docker:

docker run -d \
  -p 39999:39999 \
  -v ./sirr-data:/data \
  -v ./master.key:/run/secrets/master.key:ro \
  -e SIRR_MASTER_KEY_FILE=/run/secrets/master.key \
  -e SIRR_LICENSE_KEY=sirr_lic_... \
  ghcr.io/sirrlock/sirr

The server validates the key at startup and on each write beyond the free-tier limit. If the key is invalid or expired, the server returns 402 for writes above 100 secrets.
