Best Alternatives to withHuman in 2025
withHuman is an open-source approval layer for AI agents that intercepts tool calls before execution, automatically approving or denying routine calls based on rules and routing risky actions to the right person on your team. It works across tools like Claude Code, Codex, and agents built with LangGraph or Pydantic AI through an open protocol (AAP), letting companies apply one set of rules across their entire agent fleet. If you're looking for alternatives to withHuman, whether for different features, pricing, or integration needs, here are the best options to consider.
HumanLayer
HumanLayer is a direct competitor to withHuman, offering a human-in-the-loop approval layer for AI agents. It provides similar functionality for intercepting and approving agent actions, with a focus on API-based integrations and support for various agent frameworks. It's a strong alternative if you need a more established solution with a broader range of enterprise features.
Zapier
The automation platform for everyone
Zapier is a widely-used automation platform that can serve as an alternative for creating approval workflows. While not specifically designed for AI agents, Zapier's extensive app integrations and conditional logic allow you to build approval chains for agent actions, especially if your agents interact with SaaS tools. It's a good choice for teams already using Zapier for other automations.
Make (formerly Integromat)
Make is another automation platform that can be used to create approval workflows for AI agents. It offers more advanced logic and customization than Zapier, including error handling and complex branching, which can be useful for routing risky actions to the right person. It's a viable alternative if you need a visual builder for approval processes.
n8n
Workflow automation for everyone
n8n is an open-source automation tool that can be self-hosted, making it a great alternative for teams that prioritize data privacy and customization. Like withHuman, it's open-source, and you can build approval workflows that intercept agent actions via webhooks or APIs. It's ideal if you want full control over your approval infrastructure.
Temporal
Temporal is a workflow orchestration platform that can be used to implement human approval steps within AI agent workflows. It provides durable execution and supports long-running processes, making it suitable for complex approval scenarios. It's a more developer-centric alternative if you need robust workflow management with human tasks.
Airflow
Apache Airflow is an open-source workflow management platform that can orchestrate approval processes for AI agents. While primarily used for data pipelines, its extensibility allows you to create custom operators for human approval, and it integrates with many systems. It's a good fit for organizations already using Airflow for data workflows.
Prefect
Prefect is a modern workflow orchestration tool that supports human-in-the-loop approvals through its task and flow system. It offers a Python-native approach, making it easy to integrate with AI agents built in Python. It's a strong alternative if you want a developer-friendly platform with built-in approval mechanisms.
While withHuman offers a specialized open-source approval layer for AI agents with cross-tool compatibility, alternatives like HumanLayer provide similar dedicated functionality. For teams seeking broader automation, Zapier, Make, and n8n offer flexible workflow builders that can incorporate approvals. More developer-centric options like Temporal, Airflow, and Prefect provide robust orchestration for complex human-in-the-loop processes. The best choice depends on your specific needs: if you want a turnkey AI agent approval layer, HumanLayer is the closest competitor; if you prefer to build custom workflows within existing automation or orchestration tools, the other alternatives are excellent considerations.
