Meilisearch

What is Meilisearch?

Meilisearch is a Rust search engine with typo tolerance, filters, facets and sorting, plus semantic and hybrid search through embedders you configure. It runs as one binary or Docker container with a REST API and SDKs for most languages, so it can power site search, product search or the retrieval step of a RAG app. Advanced features such as sharding are in a separate Enterprise Edition.

Where it fits in a 10–200 person business

• Add instant, typo-tolerant search to a website, store catalogue or help center
• Combine keyword and semantic search for internal documents or a RAG retrieval layer
• Replace a hosted search service (Algolia-style) with a self-hosted engine

These use cases are our editorial suggestions, not claims made by the project.

Can a business use Meilisearch? (license)

This is a plain-English summary of the license text, not legal advice. Third-party models you run with it have their own licenses.

Data & compliance: does Meilisearch phone home?

Checked against the project's own docs and repository on Oct 29, 2026. "Not documented" means we could not find the answer in official sources; it does not mean the feature is missing or that no data is sent. Third-party services you connect (model APIs, vector databases, search engines) have their own data policies. Compare all apps.

What hardware does Meilisearch need?

The project does not publish a minimum CPU/RAM figure, so we leave the official value blank rather than guess.

The self-hosting docs do not publish a minimum host size.

How to deploy Meilisearch

Method: Docker

docker run -it --rm \
  -p 7700:7700 \
  -e MEILI_MASTER_KEY='MASTER_KEY' \
  -v $(pwd)/meili_data:/meili_data \
  getmeili/meilisearch:latest
# replace MASTER_KEY with a random key of at least 16 bytes; pin a version tag instead of latest

From the official instructions: www.meilisearch.com/docs/resources/self_hosting/getting_started/docker. Always check the source for the current version before you run it.

Known gotchas when self-hosting Meilisearch

• A self-hosted instance is only protected once you launch it with --master-key or MEILI_MASTER_KEY (at least 16 bytes of UTF-8); the start-up log confirms protection. Then send requests with the generated API keys rather than the master key. source
• Without a volume on /meili_data, indexes are deleted when the container stops. Mount a volume as in the docs. source
• The docs advise against the latest tag, and upgrading between releases uses dumps; delete data.ms in the volume before importing a dump. source
• Sharding and some other advanced features are Enterprise Edition (BUSL-1.1) and need a commercial agreement for production use. source
