Meilisearch
Worth it
Confidence: Medium
Buy if you have a developer who can run it and your data is modest . it is fast, free to self-host, and well reviewed.
| Compare | OpenSearch | Meilisearch |
|---|---|---|
| Verdict | Depends | Worth it |
| Best for | High-volume log analytics | Developers adding instant search to apps |
| Who it's not for | Small apps needing simple site search . badly overkill | Non-technical teams with no developer to run it |
| Privacy | Active open-source project with published CVEs and a clear disclosure process; recurring Log4j scanner flags and a recent DoS and SSRF issue, both patched.11 | SOC 2 Type II (Aug 2025); API keys and tenant tokens; self-hosted security is your responsibility. |
| Support quality | No support evidence in sources | No support evidence in sources |
| Public sentiment | Users praise its scale and ease of use but frequently complain about managed-hosting costs and polish versus Elasticsearch.¹ | Users broadly praise speed, lightness, and easy setup, with occasional complaints about performance on very large datasets.13 |
| Biggest gotcha | AWS Serverless bills a 2-OCU minimum around the clock; small workloads report ~$350+/month⁶ | Docs warn an exposed master key gives malicious users full access . secure self-hosts carefully. |
