EmergentDB
What it is
EmergentDB is an open-source vector database licensed under AGPL-3.0, available for self-hosting or as a managed cloud service. It automatically selects a search strategy for a dataset, without requiring manual tuning or configuration. Vectors can be inserted in batches and searched through REST API endpoints; insertion is also supported through a TypeScript SDK, and the site says any embedding source can be used. Listed index types include Flat, HNSW, IVF, PQ, and Emergent, while the SDK languages are TypeScript and Python. The free Community plan includes unlimited vectors, queries, and writes, with community support and the Bolt-lite engine. Managed Launch is listed at $24.00 per year, billed annually, with a 500K-vector limit; Scale is $66.00 per year, billed annually, and includes a dedicated instance with a 2.5M-vector limit. The site lists US, EU, and Asia-Pacific data residency, ISO 27001, SOC 2 Type II, GDPR, and HIPAA-ready status. It also describes a crash-safe write-ahead log and publishes performance claims for specified vector workloads.
