Actra

Actra is an open-source decision control system.

It evaluates policies before operations execute, allowing or blocking

actions triggered by APIs, automation systems, background workers,

or AI agents.

Core capabilities:

- Admission control for operations

- Deterministic policy evaluation

- Policy governance

- Runtime enforcement

- Support for automated and agentic systems

Key concepts:

Action : the operation being requested

Actor : the identity performing the action

Snapshot : external system state used for evaluation

Policy : rules that allow or block operations

Governance : policies that validate operational policies

Typical use cases:

- AI agent guardrails

- API safety controls

- automation workflow protection

- infrastructure safety policies

- financial operation safeguards
