The Full Ranking

Application Search (for your apps and websites)

1. Meilisearch — Best Application Search

Meilisearch is an instant, typo-tolerant search engine designed for application search. It provides sub-50ms search with zero configuration — add documents, start searching. The API is RESTful, SDKs exist for every major language, and it’s compatible with Algolia’s InstantSearch.js frontend library.

Pros:

• Instant search out of the box — no tuning required
• Typo-tolerant by default
• RESTful API with SDKs for JavaScript, Python, PHP, Ruby, Go, Rust
• InstantSearch.js compatible (Algolia’s frontend library works)
• Faceted search, filtering, sorting built-in
• Minimal resource usage (256 MB RAM for small indexes)

Cons:

• Single-node in Community Edition (no horizontal scaling without Cloud tier)
• Not designed for log analytics or aggregations
• Large datasets (100M+ records) may need more RAM

Best for: Adding search to websites, apps, and e-commerce. The closest self-hosted alternative to Algolia.

2. Typesense — Best for Speed

Typesense keeps its entire search index in RAM for sub-millisecond latency. It includes built-in high availability via Raft clustering, result curation/pinning, and search analytics — features that competitors charge extra for.

Pros:

• Sub-millisecond search latency (in-memory)
• Built-in Raft clustering for high availability (free)
• Result pinning and curation for merchandising
• InstantSearch.js compatible
• Built-in search analytics
• Geosearch, faceting, sorting

Cons:

• RAM usage scales linearly with index size (2-3x indexed data)
• Requires schema definition up front (not schema-less)
• Smaller community than Meilisearch or Elasticsearch

Best for: Applications where search speed is critical. E-commerce product search. Sites needing built-in HA without paying for it.

3. Elasticsearch — Best for Complex Search

Elasticsearch is the industry standard for search and analytics. It handles everything from simple full-text search to complex aggregations, log analytics, and the full ELK (Elasticsearch, Logstash, Kibana) stack. If you need more than basic search — analytics, dashboards, distributed scaling — Elasticsearch is the answer.

Pros:

• Most feature-rich search engine available
• Full query DSL for complex searches
• Aggregations and analytics built-in
• Horizontal scaling across clusters
• Massive ecosystem (Kibana, Logstash, Beats)
• Vector search for AI/semantic search

Cons:

• Resource-heavy (1 GB+ RAM minimum, 4 GB+ recommended)
• Complex configuration and operations
• SSPL license (not truly open source since Elastic’s license change)
• Overkill for simple application search

Best for: Log analytics, complex search requirements, large-scale deployments, teams already using the ELK stack.

4. OpenSearch — Best Elasticsearch Alternative

OpenSearch is Amazon’s fork of Elasticsearch 7.10, created after Elastic changed its license. It’s fully open source (Apache 2.0), API-compatible with Elasticsearch, and includes OpenSearch Dashboards (Kibana equivalent). If you want Elasticsearch without the license concerns, OpenSearch is a drop-in replacement.

Pros:

• Apache 2.0 license — genuinely open source
• API-compatible with Elasticsearch 7.x
• OpenSearch Dashboards included (Kibana equivalent)
• Active development with its own roadmap
• Security plugin included by default (no paid tier required)
• SQL query support built-in

Cons:

• Diverging from Elasticsearch — not all new ES features
• Smaller third-party ecosystem than Elasticsearch
• Same resource requirements as Elasticsearch
• Plugin compatibility is hit-or-miss with ES plugins

Best for: Organizations wanting Elasticsearch capabilities with a truly open-source license. AWS-native environments.

5. ManticoreSearch — Best SQL-Based Search

ManticoreSearch is a high-performance search engine forked from Sphinx Search. Its killer feature: a MySQL-compatible SQL interface. Query your search index with standard SQL clients, standard SQL syntax. If your team knows SQL, ManticoreSearch eliminates the learning curve.

Pros:

• MySQL-compatible protocol — use any MySQL client
• SQL syntax for queries (no custom DSL to learn)
• Fast full-text search with low resource usage
• Real-time indexing
• HTTP JSON API also available
• Galera-based replication for HA

Cons:

• Smaller community than Elasticsearch/Meilisearch
• Fewer SDKs and integrations
• Documentation less polished than competitors
• No InstantSearch.js compatibility

Best for: Teams who know SQL and don’t want to learn a new query language. Lightweight Elasticsearch alternative.

6. Sonic — Best Lightweight Search

Sonic is the lightest search engine you can self-host. Written in Rust, it uses less than 20 MB of RAM while providing full-text search with auto-complete suggestions. It stores only search indexes — not documents — and returns IDs that you look up in your database.

Pros:

• Extremely lightweight (10-50 MB RAM)
• Written in Rust — fast and memory-safe
• Schema-less — push text, search text
• Auto-complete/suggest built-in
• Perfect for Raspberry Pi or cheap VPS

Cons:

• No HTTP API (custom TCP protocol only)
• Returns document IDs only — not full documents
• No faceting, filtering, or aggregations
• Limited query capabilities compared to competitors
• Smaller community

Best for: Resource-constrained servers (Raspberry Pi, $5 VPS). Applications needing basic full-text search with minimal overhead.

Web Metasearch (private Google alternatives)

7. SearXNG — Best Private Web Search

SearXNG is a privacy-respecting metasearch engine that aggregates results from 70+ search engines (Google, Bing, DuckDuckGo, and more) without tracking. It strips tracking parameters, proxies images, and never sends your queries to search engines with identifying information.

Pros:

• Aggregates 70+ search engines
• Zero tracking — no cookies, no user profiles
• Image proxy hides your IP from search engines
• Highly customizable (enable/disable engines, themes)
• Active community with frequent updates
• Supports web, images, videos, news, maps, files, IT, science

Cons:

• Results quality depends on upstream engines
• Can be slow when querying many engines simultaneously
• May get rate-limited by upstream search engines
• Requires ongoing maintenance (engine configurations change)

Best for: Privacy-conscious users who want comprehensive search without tracking. Families, organizations, or networks wanting a private search portal.

8. Whoogle — Simplest Google Replacement

Whoogle is the simplest self-hosted search solution: it gives you Google search results without ads, tracking, JavaScript, or AMP links. That’s it. No configuration, no engine selection, no complexity.

Pros:

• Google results without tracking
• Zero configuration — deploy and use
• Minimal resource usage (50-100 MB RAM)
• Clean, fast interface
• Tor and proxy support

Cons:

• Google only — no other search engines
• Google may rate-limit or block your instance
• Less actively maintained than SearXNG
• No image proxy (privacy gap for image searches)
• Single point of failure (if Google blocks you, search stops)

Best for: Users who want Google-quality results without tracking and don’t need multi-engine aggregation.

How We Evaluated

We tested each search engine on: setup complexity, search speed, feature set, resource usage, community size, documentation quality, and production readiness. Application search engines were evaluated on indexing speed, query latency, relevance, and API design. Metasearch engines were evaluated on privacy, result quality, engine coverage, and reliability. All verified against official documentation as of February 2026.
