The SDK is open-source and always free. The platform offers a generous free tier — upgrade when your agents need team features, higher limits, or enterprise compliance.
Runs fully standalone with the Local UI — no Docker, no signup, nothing phones home. Connect to the platform for production observability, prompt management, evaluation dashboards, team collaboration, and HITL approval workflows.
import fastaiagent as fa fa.connect(api_key="fa-...", project="my-project") # Traces automatically sent to platform dashboard result = agent.run("Help me") # Pull versioned prompts from platform prompt = PromptRegistry().get("support-prompt") # Publish eval results to platform results = evaluate(agent, dataset=dataset) results.publish()
