Portia AI is a London open-source framework and platform for building predictable, controllable AI agents that can safely act inside business systems.
Portia focuses on the gap between flashy agent demos and production reliability: its SDK lets developers define tools, plans and approval steps so agents do exactly what’s intended in sensitive systems. With secure credential handling, human-in-the-loop checkpoints and observability, Portia suits enterprise automation where mistakes are costly. The company offers both an open-source library and a managed cloud for running agents at scale.
The Portia SDK is free and open source; the managed cloud platform offers free tiers for development with paid plans for production scale.
Developers and platform teams building agents that act on real business data — email, CRMs, internal APIs — with safety requirements.
Portia is for agents that must act in real business systems without going off-script.
Install the open-source SDK, register tools and define a plan; the managed cloud takes over when you are ready for production scale.
Agents that behave predictably in production, with logs and approvals that satisfy security teams.
The open-source SDK gets agents running locally; the managed cloud handles credentials, approvals and observability as usage scales.
Agent reliability depends on careful tool definition, and sensitive actions still deserve human approval gates.
Developers value run logs and approval steps that make agents defensible in production.
Agents that act need guardrails more than cleverness. Portia’s plans, approvals and credential handling make automation defensible in exactly the business systems where errors are expensive. Open source means you can evaluate the safety model yourself.
Yes — the framework is open source and the cloud has a free tier; paid plans cover production workloads and enterprise support.
Yes — agents built with Portia can be triggered and managed through APIs, and tools are defined as typed integrations.
Against general agent frameworks, Portia emphasizes controllability — plans, approvals and credentials — making it safer for business-critical automation.
