Open core, self-hostable, and ready to inspect
The FastPII Python SDK is Apache 2.0 licensed and designed so developers can audit the implementation, self-host the runtime, and contribute improvements directly.
Apache 2.0 SDK
Use the SDK as an auditable building block for local security controls, self-hosted deployments, and custom AI protection workflows.
A security layer you can inspect for yourself
Open source makes FastPII easier to evaluate, easier to self-host, and easier to adapt to internal engineering standards.
Apache 2.0
Review licensing terms that support internal adoption, distribution, and contribution workflows.
Zero external dependencies
Keep the install surface small when bringing FastPII into your own Python environments.
Self-hosting
Run the security layer in infrastructure your organisation already trusts and manages.
Start with the open-source layer, then expand when you need more
Teams can begin with the SDK, then add gateway, governance, and audit layers while keeping the same FastPII protection model.
