# openfirma vs Aegis

*GraphCanon updated Sep 20, 2026*

## Verdict

Pick openfirma if openfirma is a policy-enforcing sidecar for AI agents that uses Cedar policies to gate outbound calls, built in Rust under the GPL-3.0 license; pick Aegis if aegis provides runtime policy enforcement for AI agents with cryptographic audit trails and human-in-the-loop approvals, supporting zero-code deployment switches suited for various compliance needs.

[openfirma](https://firma-ai.github.io/openfirma/) reports 135 GitHub stars, 9 forks, and 8 open issues, last pushed Sep 11, 2026. [Aegis](https://github.com/Justin0504/Aegis) has 340 stars, 37 forks, and 3 open issues, last pushed Sep 6, 2026. Figures are from public GitHub metadata via [openfirma's repository](https://github.com/Firma-AI/openfirma) and [Aegis's repository](https://github.com/Justin0504/Aegis).

## Decision facts: openfirma

- **Adopt for:** Openfirma is a policy-enforcing sidecar for AI agents that uses Cedar policies to gate outbound calls, built in Rust under the GPL-3.0 license.

## Decision facts: Aegis

- **Adopt for:** Aegis provides runtime policy enforcement for AI agents with cryptographic audit trails and human-in-the-loop approvals, supporting zero-code deployment switches suited for various compliance needs.

## Choose when

### Choose openfirma if…

- openfirma is primarily Rust; Aegis is TypeScript.
- License: openfirma is GPL-3.0, Aegis is MIT.
- Tags unique to openfirma: access-control, agentic-ai, ai-agents, authorization.
- When you need deterministic and call-level runtime enforcement that specifically leverages Cedar policies tailored for your needs.

### Choose Aegis if…

- Aegis is primarily TypeScript; openfirma is Rust.
- License: Aegis is MIT, openfirma is GPL-3.0.
- Tags unique to Aegis: ai-safety, anthropic, audit-trail, llm-observability.
- Aegis ships Docker support for self-hosted deployment.
- You need cryptographic assurance of the audit trail to meet high-security standards.

## When NOT to use openfirma

- Avoid if you prefer a solution not tightly coupled to Cedar policies, as Openfirma exclusively supports this policy framework.
- Do not use if licensing is critical and you need permissive licenses, since Openfirma uses the GPL-3.0 license.

## When NOT to use Aegis

- The project does not require a zero-code deployment switch and can manage changes directly in the codebase.
- Minimal regulatory requirements mean that elaborate configurations like Aegis's strict retention policies are unnecessary.
