HumanLayer

Standing up an AI teammate used to be a weekend hobby with a side of chaos. Today it slots into your stack in about five minutes, then behaves like it read the onboarding doc.

HumanLayer lets you build AI agents that feel like real coworkers, not chatbots in costume. Use clean Python or TypeScript SDKs, bring your own LLM, and orchestrate with LangChain, OpenAI, or CrewAI. Ship agents to Slack, email, and Discord so they work where your customers and teams already live.

Control stays in your hands. Sensitive actions require approval, with denial feedback sent back to the model. Route tasks to the right team or person, set escalations, and keep long-running workflows reliable with 12 Factor Agents. Human as Tool brings people into the loop on demand, so agents pause, wait for direction, and finish the job without going off the rails.

Governance is built in. Export live human feedback as labeled datasets for training or evals. Choose private deployment, RBAC and SSO, and data retention policies that match your compliance needs. Start free, scale to Premium or Enterprise when you are ready.

For online businesses, this means fewer copy-paste marathons and more closed tickets, faster follow-ups, and clean audit trails. Your agent handles the busywork across channels. You keep the keys and the receipts.
