Cayu
Cayu is a Python framework for constructing domain-specific AI agents that combine model reasoning with typed tools, policies, and durable runtime execution. Developers define an agent's identity and model, attach narrow business tools with input schemas and effect contracts, and register context and tool policies that control what the model sees and what may execute. The runtime carries out the model-and-tool loop, records progress, and pauses for structured human approval before sensitive actions such as submitting a proposal or recording an order. A knowledge store holds durable guidance that can be recalled into context, while business records remain separate. The framework is aimed at teams that want to build custom agent applications in normal Python modules rather than through a no-code interface.
Cayu is a Python framework for constructing domain-specific AI agents, priced at $175/month on the Purchase plan. InnovaAI scores it 3.3/10 for agency resale.
Agency Audit
Cayu is a developer framework rather than a turnkey agency tool, giving Python teams the building blocks to assemble agents with explicit tools, policies, and approval gates. Its runtime handles execution records and human review pauses, which matters for workflows where an agent must not act without sign-off. For agencies with engineering capacity, it is a foundation for custom client-facing agent applications.

Platform Features
Core capabilities of Cayu
Enforce approval gates
UniquePauses execution and requires a structured human decision before sensitive tools run.
Control tool exposure
UniqueDecides which registered tools the model can see using a static exposure policy.
Define typed agent tools
Gives the model named actions with declared input schemas and read-only or mutating effect contracts.
Manage knowledge recall
Stores durable guidance and controls which knowledge enters the model's context.
Run durable sessions
Maintains session and task stores so agent runs can pause and continue across steps.
What Makes Cayu Different
Unique advantages vs similar tools in this niche
Approval gates pause execution until a structured decision resolves the exact pending call
vs Frameworks that let the model self-report approval in textThe model saying 'approved' does not resolve the gate; the application submits a structured decision for the exact pending call.
Separates knowledge, business records, and context into distinct stores
vs Frameworks that mix retrieval and application data in one context windowKnowledge is durable guidance, business records are inventory and proposals, and context is what the model sees for its next decision.
Frequently Asked Questions
Answers about pricing, setup, alternatives
Cayu offers 1 pricing tier, at $175/mo (Purchase).
Cayu's most distinctive features include: Enforce approval gates (Pauses execution and requires a structured human decision before sensitive tools run.); Control tool exposure (Decides which registered tools the model can see using a static exposure policy.). These capabilities differentiate Cayu from alternatives and create unique value for agency clients.
Cayu's key advantage over Frameworks that let the model self-report approval in text: Approval gates pause execution until a structured decision resolves the exact pending call. The model saying 'approved' does not resolve the gate; the application submits a structured decision for the exact pending call. Overall: Cayu is a developer framework rather than a turnkey agency tool, giving Python teams the building blocks to assemble agents with explicit tools, policies, and approval gates. Its runtime handles execution records and human review pauses, which matters for workflows where an agent must not act without sign-off. For agencies with engineering capacity, it is a foundation for custom client-facing agent applications.
Cayu is a strong fit if: Your agency has Python developers who want to build custom agent applications; You need approval gates and durable execution records around agent actions; You want to keep business logic in your own code rather than a no-code builder. Consider alternatives if: Your agency lacks Python development staff; You need a ready-made agent product you can deploy immediately. Key trade-off: It requires Python development work and a configured model provider credential, so there is no out-of-the-box product an agency can deploy without building the domain harness itself.
