In their own words
Actian Zen
Actian Zen is an embedded database for managing data from edge devices through on-premises and cloud applications. Its lightweight engine combines relational storage, native vector search, semantic queries, and connectivity for AI agents. Vector search supports up to 1 million vectors, while hybrid queries combine relational filters with semantic similarity. A native MCP server allows agents such as ChatGPT, Claude, and Gemini to query local data. Zen supports SQL through ODBC and JDBC, and NoSQL through Btrieve and Btrieve 2 APIs. Semantic search, vector queries, and agent workflows can run offline, including in air-gapped environments. Zen Enterprise is designed for embedded, on-premises, and cloud deployments, including branch and remote field settings, and supports Windows, Linux, macOS, Intel, ARM, VMware, Hyper-V, and Docker. Zen Mobile supports Android and iOS with AES 256-bit encryption for stored data. Edge supports over 100 concurrent users; Enterprise is designed for thousands. A 30-day trial is available, with paid pricing from $417/mo (annual).
