## Choose when

### Choose humanbound if…

- License: humanbound is Other, prismor is Apache-2.0.
- Tags unique to humanbound: adversarial-testing, agentic-ai, multimodal-ai, security-testing.
- When you need to test your AI agent's resilience against prompt injection attacks, utilize humanbound’s specialized features tailored for this purpose

### Choose prismor if…

- License: prismor is Apache-2.0, humanbound is Other.
- Pricing: Free with a commercial license for advanced features..
- Requirements: Min 1 GB RAM.
