Source: https://altcatalog.com/alternatives/vespa/ Category: Vector databases ## Overview - **Who it's for**: Vespa is aimed at engineering teams building large-scale search, recommendation, RAG, and personalization systems that need to combine vector search, text search, and structured filtering with low-latency serving. - **What you get**: Vespa is an open-source (Apache 2.0) big-data serving engine with built-in approximate nearest-neighbor vector search, hybrid (vector + keyword) retrieval, machine-learned ranking, and real-time partial updates, which you can self-host or run on the managed Vespa Cloud. - **How it works**: Documents, including vector/tensor fields, text, and structured data, are indexed across horizontally scalable content clusters; queries use Vespa's YQL query language to combine nearest-neighbor search, text matching, and filters, with ranking computed locally on the nodes holding the data for speed at scale. ## Profile - **License**: Apache-2.0 (verified 2026-07-16) - **Pricing model**: OSS + paid hosting (verified 2026-07-16) - **Starts at**: $0.05/vCPU-hour (Vespa Cloud Startup plan, usage-based) (verified 2026-07-16) - **Platforms**: Linux, macOS, Windows, Web - **Status**: active (verified 2026-07-16) ## Ranked alternatives | # | App | Alt Score | Licence | Platforms | |---|-----|-----------|---------|-----------| | 1 | [Chroma](https://altcatalog.com/alternatives/chroma.md) | 93 | Apache-2.0 | Windows, macOS, Linux | | 2 | [LanceDB](https://altcatalog.com/alternatives/lancedb.md) | 93 | Apache License 2.0 | ? | | 3 | [Milvus](https://altcatalog.com/alternatives/milvus.md) | 89 | Apache License 2.0 | Linux, macOS, Windows | | 4 | [Qdrant](https://altcatalog.com/alternatives/qdrant.md) | 86 | Apache License 2.0 | Web, Windows, macOS, Linux | | 5 | [Pinecone](https://altcatalog.com/alternatives/pinecone.md) | 83 | Proprietary | Web | | 6 | [pgvector](https://altcatalog.com/alternatives/pgvector.md) | 79 | PostgreSQL License | Linux, macOS, Windows | | 7 | [Weaviate](https://altcatalog.com/alternatives/weaviate.md) | 79 | BSD 3-Clause License | Web, Linux, macOS, Windows | | 8 | [turbopuffer](https://altcatalog.com/alternatives/turbopuffer.md) | 68 | Proprietary | Web | Alt Score = Verified coverage (90%) + Visibility (10%).
