Features and specs

What each product offers, as listed by its team.

Oso 5 features
Actera.dev 5 features
  • Declarative policy language
    Oso provides a declarative policy language called Polar that allows developers to write clear and concise authorization policies, making it easier to manage and understand access control rules.
  • Integrations
    Oso integrates easily with popular frameworks and languages, offering flexibility for developers to incorporate authorization functionality within their existing tech stack.
  • Fine-grained access control
    Oso supports fine-grained access control, enabling developers to specify precise permissions at various levels, such as user, role, and resource, enhancing security and customization.
  • Community and support
    Oso has an active community and provides resources such as documentation, guides, and support channels, helping developers with implementation and troubleshooting.
  • Policy simulation and testing
    Oso offers policy simulation and testing tools, allowing developers to test and validate authorization policies before deploying them in production environments.

Possible disadvantages

  • Learning curve
    Oso's Polar language may have a learning curve for developers unfamiliar with declarative policy languages, requiring time and effort to become proficient.
  • Complexity in large systems
    Managing authorization in very large systems can become complex with Oso, especially if the policies require extensive customization and fine-tuning.
  • Potential performance overhead
    Depending on how Oso is integrated and used, there may be some performance overhead, particularly in systems with high traffic and extensive authorization checks.
  • Limited offline usage
    Oso primarily functions as a cloud-based solution, which may limit its usage in environments requiring full offline operations or on-premise deployments.
  • Policy decisions
    Allow, require approval or block each agent action before it runs
  • Human approval
    Routes actions to the right approver with full context; the action resumes once approved
  • Context-aware rules
    Policies use prior approvals, workflow state, spend so far and other agents' actions
  • Audit trail
    Every decision is recorded with the policy behind it
  • Integrations
    Claude Code and Codex plugins, TypeScript SDK, remote MCP connector for Claude

Questions & Answers

As answered by people managing Oso and Actera.dev.

What makes your product unique?

Actera.dev's answer:

Actera checks each action an AI agent tries to take before it runs, not after. Every action gets one of three outcomes: allowed, sent for approval, or blocked. Decisions use live context, such as approvals already given, the state of the workflow, spend so far today and what other agents have done, so one policy can give different answers to the same request. Policies are enforced outside the model, so no prompt, model update or clever wording can change them.

Why should a person choose your product over its competitors?

Actera.dev's answer:

Authorization tools like Cerbos and Permit.io answer whether a user may access a resource. Actera is built for agent actions: it adds approval routing with full context, actions that resume once approved, and a decision record with the policy behind every attempt. It also ships ready-made enforcement for coding agents (open-source plugins for Claude Code and Codex), a TypeScript SDK for your own agents, and a remote MCP connector so policies can be reviewed and written from Claude. Teams can test rules on real scenarios before publishing them, and there is a free plan.

How would you describe the primary audience of your product?

Actera.dev's answer:

Companies putting AI agents to work on real systems: engineering teams running coding agents such as Claude Code and Codex, and product teams building agents that issue refunds, change records, export data or deploy code. Finance, engineering and operations leads use Actera to set what each agent can do on its own, what needs approval and what is off limits, and compliance teams use the decision record to show auditors why an agent acted.

Which are the primary technologies used for building your product?

Actera.dev's answer:

Go for the API and policy engine, with gRPC and protobuf contracts, PostgreSQL and Redis. The web app is React and TypeScript. It runs on Kubernetes on AWS. Integrations include a TypeScript SDK, plugins for Claude Code and Codex built on their hook systems, and a remote MCP server for Claude.
