Open-source Search tools

Three things to check when comparing search tools

License bucket: Permissive, weak-copyleft, strong-copyleft or source-available — the bucket decides whether you can modify, embed or host the project as a service. Each alternatives page groups its projects by bucket; confirm the LICENSE file in the linked repository.
Last push: The last-pushed date on each card comes from the GitHub public API as of the last daily data refresh. Compare it across the projects in a category before reading feature lists.
Migration path: Read the migration tips on each alternatives page, then check the project's own documentation for an importer or export format before planning a cut-over. Pages without migration tips omit that section rather than fill it in.

Algolia alternatives

Algolia is a hosted search-as-a-service platform delivering typo-tolerant, faceted, and ranked search results via a REST API. It handles indexing, relevance tuning, and infrastructure, letting teams add product search, site search, or content discovery to applications without managing a search cluster. Its speed focus (sub-100ms responses) and merchandising rules are its primary differentiators.
