Vespa is an AI search platform for online, data-driven applications that combines retrieval, ranking, machine-learning inference, and real-time serving. It supports vector and tensor search, positional text search, and structured-data search. Ranking signals can be combined through tensor functions or models in formats such as ONNX and XGBoost; Vespa also supports inference using ONNX Runtime. Its functions are distributed across node clusters, and cluster size can change without affecting queries or writes. Teams can self-manage deployments, use the Vespa Kubernetes Operator, or deploy on Vespa Cloud. Local deployment guidance lists Linux, macOS, and Windows 10 Pro on x86_64 or arm64 with Docker Desktop or Podman Desktop. Vespa Cloud encrypts data at rest and in transit, uses node and endpoint certificates, and automatically updates OS patches. A cloud trial includes $300 in usage credits, requires no credit card, and stops the application when credits run out. Cloud plans have quotas; Startup is limited to development zones.
Who it is for
Vespa describes its platform for teams building AI applications where search quality, ranking, fresh real-time data, or growing retrieval traffic matter. It suits teams choosing between self-managed deployment, an operator, and Vespa Cloud.
What is good
- Supports vector, tensor, positional text, and structured-data search.
- Can scale clusters without impacting queries or writes.
- Supports ONNX and XGBoost ranking models.
- Cloud trial includes $300 in credits without a card.
- Cloud handles encryption and automatic OS patching.
What to know first
- Cloud plans have quotas.
- Startup is limited to development zones.
- Startup has community support only, with no SLA.
- Enclave adds cloud-provider resource costs.
Verdict
Vespa offers varied search and ranking methods alongside self-managed and cloud deployment paths. Teams should account for Cloud quotas, the Startup plan’s development-zone limit, and trial credits that stop the application when depleted.
