It supports both full-text and vector searches. ## Decision facts: SPTAG - **Pricing:** freemium - SPTAG is open source and free to use under the MIT license. Advanced support or integrations may bear extra costs depending on commercial context. - **Requirements:** Requires proficiency in C++ for optimal customization, though general usage can be managed with provided toolkits.; High infrastructure demands due to its distributed nature make efficient resource management a priority. - **Adopt for:** SPTAG is optimal for developers and enterprises handling large-scale vector searches who need high-quality indexing with efficient serving mechanisms. ## Choose when ### Choose meilisearch if… - meilisearch is primarily Rust; SPTAG is C++. - License: meilisearch is Other, SPTAG is MIT. - Tags unique to meilisearch: ai, api, app-search, database. - Also covers Data & Retrieval. - - You require fast integration capabilities for your web or mobile application, as Meilisearch offers flexible deployment options. ### Choose SPTAG if… - SPTAG is primarily C++; meilisearch is Rust. - License: SPTAG is MIT, meilisearch is Other. - Pricing: SPTAG is open source and free to use under the MIT license.
