Meilisearch vs Vespa

Meilisearch is a search engine that can be added to websites and applications, with self-hosted and cloud deployment options. Full-text search includes automatic typo tolerance and relevance ranking; hybrid search combines keyword precision with semantic understanding. The product also provides retrieval infrastructure for RAG with hybrid retrieval and LangChain support, alongside faceted, federated, multimodal, personalized, and conversational search. Meilisearch supports more than 30 languages with automatic language detection and smart tokenization. Its SDKs, plugins, and integrations cover programming languages and frameworks including JavaScript, Python, PHP, Ruby, Go, Rust, Java,.NET, Swift, and Dart. The company says results return in under 50 milliseconds for typical workloads. Self-hosting costs nothing under the MIT license, but users manage infrastructure, updates, backups, and scaling. Cloud starts at $20 a month, with a 14-day free trial, usage- or resource-based billing, and email support. Enterprise pricing is custom and includes dedicated resources and Slack support. Meilisearch says its security measures include encryption, monitoring, assessments, and compliance measures including GDPR and SOC 2 Type 2.

Vespa is an AI search platform for online applications that use data, retrieval, ranking, machine-learning inference, and real-time serving. It supports vector and tensor search, positional text search, and queries over structured data. Ranking signals can be combined with tensor functions or machine-learned models, including ONNX and XGBoost formats; model inference can use ONNX Runtime. Vespa distributes functions across node clusters and allows cluster size changes without affecting queries or writes. Teams can self-manage deployments, use the Vespa Kubernetes Operator, or run 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 includes encryption at rest and in transit, certificates for nodes and endpoints, and automatic operating system patching. Its trial provides $300 in credits without requiring a credit card, then stops the application when credits are used. Cloud plans have quotas, and Startup is limited to development zones. Pricing is listed from $0.05 a month, with metered resource rates.
