The alternatives in detail
In order of how closely each one matches Zenity.
CalypsoAI
4.1Not listed
vs Zenity−0.1
AI guardrails, now part of F5, protecting generative AI applications in production.
- Runtime guardrails between the model and the user
- Protection against prompt injection and data leakage
- Policy enforcement across cloud deployments
Backed by an established security vendor rather than a startup
Enterprise procurement through F5 rather than self-serve
Prediction Guard
3.5Not listed
vs Zenity−0.7
A self-hosted, zero-trust control plane for enterprise AI agents - deploy, govern, and observe agents across OpenAI, Anthropic, and MCP with 4x lower total cost than compliance alternatives.
- Self-hosted, zero-trust control plane for enterprise AI agents
- OpenAI, Anthropic, and MCP-compatible interfaces
- Works with LangChain, CrewAI, and other agent frameworks
On-premises deployment gives real sovereign control, not just a dashboard
Pricing isn't published - enterprise sales-driven
Traceable
