Glider is a single-node vector database that uses S3-compatible object storage as its only durable state, ensuring every write is persisted before acknowledgment. It offers nearest-neighbor search with metadata filters via HTTP/JSON, includes Python and MCP clients for AI agent memory, and provides robust features like crash-safe takeover and retry-safe writes. Its innovative architecture and thorough documentation make it a compelling solution for durable, cloud-native vector search.

Target audience: backend developers, AI engineers, data engineers, DevOps
