OSI-licensed only · self-hostable
Algolia is a hosted search API: you push records to it and query with typo tolerance, filters and instant results. The open-source options let you run the engine yourself, with the data staying on your own infrastructure, and some can run entirely in the browser or at build time.
Every tool below is under an OSI-approved licence (GPL-3.0, MIT, Apache-2.0 or GPL-2.0+), checked against its repository. Elasticsearch is left out because the licence was not shown on its repository page when we checked; verify its current licence before choosing it. Meilisearch's repository also contains a separately licensed Enterprise Edition, noted below.
Licences checked against each repository on November 7, 2026.
| Tool | Best for | Licence | Runs as |
|---|---|---|---|
| Typesense | Closest drop-in replacement | GPL-3.0 | Docker |
| Meilisearch | Fast search with hybrid and semantic options | MIT | Docker |
| OpenSearch | Large-scale search and analytics | Apache-2.0 | Server |
| Manticore Search | SQL-style search database | GPL-3.0 | Server |
| Orama | Search that runs in the browser or at the edge | Apache-2.0 | Server |
| Pagefind | Search for static sites | MIT | Server |
| Tantivy | Rust library to build your own search | MIT | Server |
Best for: Closest drop-in replacement
A fast, typo-tolerant search engine that describes itself as an open-source Algolia alternative. The server is GPL-3.0 while its client libraries are Apache licensed.
Best for: Fast search with hybrid and semantic options
A search engine API for full-text, semantic and hybrid search. The Community Edition is MIT; an Enterprise Edition in the same repo needs a commercial agreement for production.
Best for: Large-scale search and analytics
A distributed, RESTful search and observability suite under Apache-2.0.
Best for: SQL-style search database
An easy-to-use, open-source database designed for search, with full-text, vector and hybrid search and real-time indexing.
Best for: Search that runs in the browser or at the edge
A search engine and RAG toolkit that runs in browsers, on servers or at the edge, supporting keyword, vector and hybrid search in a small package.
Best for: Search for static sites
A fully static search library designed to perform well on large sites, using little bandwidth and needing no hosted infrastructure.
Best for: Rust library to build your own search
A fast full-text search engine library in Rust, closer to Apache Lucene than to Elasticsearch, with BM25 scoring and multiple tokenizers.

Quick answers to common questions
Algolia is hosted and proprietary. Typesense describes itself as an open-source Algolia alternative and is the closest equivalent.
Both run as a single service and can be deployed with Docker. Compare the licences first: Typesense's server is GPL-3.0, while Meilisearch's Community Edition is MIT.
The Community Edition is MIT licensed. The repository also contains an Enterprise Edition under a commercial licence or the Business Source License, so check which edition you use.
Pagefind builds a static index for static sites, and Orama can run in the browser, so small sites can avoid a search server entirely.
Its licence was not visible on the repository page we checked, so confirm its current licence yourself. OpenSearch is the Apache-2.0 option from the same family of tools.
List it on TechLogHub and we'll review it for this page.
