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.
Vearch
Vearch is a free, open-source, cloud-native distributed vector database for similarity search in AI applications. It searches embedding vectors and can combine vector queries with scalar filtering for metadata conditions. The project describes replication and elastic scale-out and says it can retrieve vectors among millions of objects in milliseconds. Its Router exposes REST operations for upserting, deleting, searching, and querying data. Client SDKs are listed for Python, Go, Java, and Rust, with integrations for LangChain, LlamaIndex, LangChainGo, and LangChain4j. Deployment options include Kubernetes through Helm, Docker Compose in standalone or cluster mode, Docker, and compilation from source. PartitionServer uses Raft-based replication for document partitions, while Gamma is a Faiss-based vector search engine. Vearch is licensed under Apache License 2.0 and supports Linux and macOS self-hosted deployments. Community support is available through GitHub Issues, an email discussion group, and Slack. The VisualSearch demo requires an image retrieval plugin for object detection and feature extraction.
