Algolia vs self-hosted search for PrestaShop: when each option pays off
Algolia is great when you need it and overkill when you don't. A practical breakdown of the operations cost of each path for PrestaShop stores at three scale points.
Algolia is a great search engine. If you've never used it on a large catalogue, you should at least play with their developer dashboard once — the relevance tuning UX is genuinely best-in-class. That's the easy part of this comparison.
The harder question is: for your PrestaShop store, is it worth the operational shape?
The Algolia pricing model
Algolia's "Build" tier is free for up to 10k records and 10k search operations / month. Beyond that, you pay per operation + per record. For a 50k SKU PrestaShop store with moderate traffic, that lands in the €100–€300 / month range historically. A 300k SKU store with higher traffic can be €500–€1,500 / month.
Variable cost is the key word. Bill scales with traffic, not with revenue. A SEO content win that doubles your traffic can also double the search bill before it changes your conversion.
Three scale points
5,000 SKUs, ~30 searches / day
Algolia is free here. Self-hosted is also free (NP Search is €89 one-time). Either works. Choose by operational fit: do you want the Algolia dashboard's polish, or do you want to keep the index in your own database for GDPR / DPA simplification?
50,000 SKUs, ~5,000 searches / day
Algolia ≈ €100–€300/month. NP Search ≈ €89 one-time + €58/year for optional updates. 3-year TCO: €4k–€11k vs €290. The math is unambiguous unless your team materially benefits from Algolia's tooling (relevance dashboard, A/B testing, the developer SDK).
500,000+ SKUs, ~50,000+ searches / day
This is where Algolia earns its keep. Sharding, regional replicas, per-user personalization at scale — these are real engineering problems that hosted search solves cleanly. Self-hosted starts to cost engineering time at this scale.
Recommendation: switch to Algolia or Searchspring around the 300k SKU mark, or earlier if your business is search-relevance- differentiated (luxury fashion, electronics with deep variant trees).
The hidden operational dimension: relevance debugging
The most underappreciated cost of any hosted search service is "why isn't this product showing up?" debugging. Algolia's dashboard is excellent at this; their query insights, replica indexes, and relevance overrides genuinely accelerate this work.
Self-hosted search makes you query the index directly. SQL-skilled ops teams find this fine; non-technical merchandising teams may not.
The migration shape (either direction)
Migrating from Algolia to self-hosted:
- Export synonyms + searchandising rules from Algolia dashboard (JSON).
- Import into NP Search admin (we have a script that maps the JSON).
- Run both in shadow for a week, compare top queries + zero-result rate.
- Flip, cancel Algolia.
Migrating from self-hosted to Algolia: their import tooling is excellent and well-documented; expect a single afternoon of work.
Symmetric migration cost in both directions, which is unusual for infrastructure choices. Make the decision for now; revisit when the math changes.
Decision quick reference
| Your situation | Pick |
|---|---|
| Under 50k SKUs, no merchandising team | NP Search |
| 50k–300k SKUs, GDPR-sensitive vertical | NP Search |
| 50k–300k SKUs, dedicated merchandising team | Either; weigh dashboard polish |
| 300k+ SKUs, high traffic, per-user personalization | Algolia or Searchspring |
| Multi-storefront, multi-region, multi-currency | Algolia (sharded replicas) |
Bottom line
Algolia is the right answer at scale. Self-hosted is the right answer for the vast majority of PrestaShop stores that aren't at that scale. The middle ground depends on whether dashboard polish is worth €100+/month forever to your specific team.
