What is Epsilla?
Epsilla is an agent-as-a-service platform where teams build and deploy AI applications over their own knowledge bases without writing code. A drag-and-drop builder and retrieval-augmented generation are combined with tools for monitoring agent performance.
The platform includes a no-code agent builder, RAG as a service, and management tools to analyze and tune chatbots and agents. Its homepage also promotes HarnessRouter, an open-source layer with a single API for running agent harnesses such as Codex and Claude Code in serverless sandboxes.
Plans scale by team members, projects, AI applications and knowledge bases, with add-ons for vector storage, extra messages and removing the Epsilla badge. A higher tier adds a forward-deployed engineer who builds agents and workflows for you.
