Layer 3 · self-hosting reality check
What it actually takes to self-host Meilisearch
The docs say 1 GB. In practice you want 4 GB — it wants the index resident in memory. Here is the honest version — real requirements, real monthly cost, what you will be maintaining, and the one thing that catches people out.
Usually reached from Algolia alternatives, where Meilisearch is one of the picks.
Wondering whether you need to at all? Is Algolia free? — what the free tier actually allows, and where the wall is.
| RAM — documented minimum | 1 GB |
|---|---|
| RAM — what it really needs | 4 GB — it wants the index resident in memory |
| CPU | 2 vCPU |
| Disk | Roughly 2–4× the raw document size |
| Monthly cost | $15–30/mo, against Algolia pricing that scales per search operation |
| Setup time | 1 hour |
| How you install it | single binary or container — genuinely one process, which is the appeal |
| Ongoing maintenance | Low. Reindexing on schema change is the main operation. |
| Where it stops scaling | Millions of documents on a well-sized box. Sharding is not its strength. |
The thing that catches people out
It is memory-bound, not disk-bound, and the failure is ugly: exceed available RAM and indexing dies rather than degrading. Size for the index in memory plus headroom for merges, and watch it as the corpus grows — this catches teams who sized against document count instead of index size.
When not to self-host Meilisearch
You need complex aggregations, faceted analytics or geo queries at scale. Meilisearch optimises for fast, typo-tolerant, straightforward search.
Every guide here carries this section. A site that only ever tells you to self-host is selling something — the useful answer is sometimes no.

- What does self-hosting Meilisearch cost per month?
- $15–30/mo, against Algolia pricing that scales per search operation This is commodity VPS pricing and excludes your time, which is the larger cost for most people — budget for low. Reindexing on schema change is the main operation.
