Epsilla
Epsilla lets enterprises build and deploy vertical AI agents without standing up their own LLM infrastructure. The Agent-as-a-Service platform combines a no-code builder, managed RAG over private knowledge bases, and multi-tenant access controls so teams can ship domain-specific chatbots from one console.
General agent frameworks expect engineering time for retrieval pipelines, hosting, and permissions. Epsilla packages those pieces as a service with drag-and-drop flows, pre-built industry templates, and deployment options across SaaS, on-premise, or private cloud. Professional tiers add 10 GB vector storage and 5,000 monthly messages on GPT-4.1, while the AI Concierge plan layers a fractional forward-deployed engineer for done-for-you workflow build-out.
Operations teams in manufacturing, healthcare, legal, and financial services use Epsilla when they need retrieval-quality answers over proprietary documents without hiring a full platform team.
Free tier includes 1 AI application, 1 knowledge base, 10M vector storage, and 50 GPT-4.1 messages monthly
No-code drag-and-drop builder creates conversational flows without writing application code
Managed RAG service ingests enterprise documents across formats into searchable knowledge bases
Professional plan supports 50 AI applications, 50 knowledge bases, and 5,000 messages per month
Enterprise multi-tenancy sets granular permissions across teams from a single admin console
Deployment options include managed SaaS, on-premise install, or private cloud hosting
Bundles no-code agent building, managed RAG, and hosting in one Agent-as-a-Service platform.
Supports SaaS, on-premise, and private cloud deployment for compliance-heavy industries.
Free tier lets teams prototype agents with GPT-4.1 before upgrading message quotas.
Message caps on self-serve tiers can limit high-traffic production chatbots.
AI Concierge and Enterprise pricing sit far above self-serve plans for hands-on support.
Inactive free workspaces lose data after 30 days per the free tier policy.
