Epsilla

Epsilla is an enterprise-grade Agent-as-a-Service platform that lets businesses build and deploy vertical AI agents without deep engineering overhead. A drag-and-drop builder and a RAG-as-a-Service layer mean non-technical teams can upload documents, connect data sources, choose models and publish a working agent or chatbot in minutes, while developers still get an API for wiring the same agents into their own interfaces. The platform handles vector storage, embedding, indexing and retrieval so teams do not have to stand up and maintain their own vector database stack.

Beyond agent creation, Epsilla focuses on agent and chatbot management: monitoring, analytics and optimization tools help teams see how agents perform and improve them over time. Enterprise requirements are covered with multi-tenancy, granular permissions and access controls, plus deployment options spanning managed SaaS, on-premise installation and private cloud for security and compliance needs. Solutions are organized around verticals including manufacturing, research management, inbound sales and customer support, construction, publishing and libraries, financial services, healthcare and legal.

Epsilla also runs on HarnessRouter, a unified interface for agent harnesses that exposes Codex, Claude Code and other harnesses through a single Agent API with serverless sandboxes, sessions, streaming, files and cost controls. Customers quoted on the site include teams at TigerGraph, Stanford School of Medicine and Seoul National University. Entry is free, with paid plans and enterprise pricing available through a demo request.
