In their own words
Epsilla
Epsilla is an Agent-as-a-Service platform for creating and deploying vertical AI agents without infrastructure complexity. Its drag-and-drop builder is intended for no-code agent creation, while retrieval-augmented generation connects agents to enterprise knowledge bases. Users can upload PDF, DOCX, CSV, HTML, and JSON documents from local drives, cloud drives, or web pages, then configure chat history, top-K retrieval, and metadata filtering. Management tools monitor, analyze, and optimize agents and chatbots. Multi-tenancy provides granular permissions and access controls. Deployment options include managed SaaS, on-premise installation, and private cloud, with web service APIs for custom interfaces. TokenRouter provides access to commercial and open-source models through one API key. Epsilla lists solutions for manufacturing, research management, sales and support, publishing, financial services, healthcare, and legal services. It runs as an API, self-hosted deployment, or web service. The Free Tier costs nothing; paid plans start at $29 a month, with larger tiers and an enterprise option.
Vespa
Vespa is an AI search platform for online applications that use data, retrieval, ranking, machine-learning inference, and real-time serving. It supports vector and tensor search, positional text search, and queries over structured data. Ranking signals can be combined with tensor functions or machine-learned models, including ONNX and XGBoost formats; model inference can use ONNX Runtime. Vespa distributes functions across node clusters and allows cluster size changes without affecting queries or writes. Teams can self-manage deployments, use the Vespa Kubernetes Operator, or run on Vespa Cloud. Local deployment guidance lists Linux, macOS, and Windows 10 Pro on x86_64 or arm64 with Docker Desktop or Podman Desktop. Vespa Cloud includes encryption at rest and in transit, certificates for nodes and endpoints, and automatic operating system patching. Its trial provides $300 in credits without requiring a credit card, then stops the application when credits are used. Cloud plans have quotas, and Startup is limited to development zones. Pricing is listed from $0.05 a month, with metered resource rates.
