Weaviate plans, side by side
Every published tier in ascending order of price, with the number of features each one lists. An absence here means the record does not itemise it, not that the tier lacks it.
| Plan | Price | Features listed | Step up from the tier below |
|---|---|---|---|
| Open Source | Free | 2 | Entry tier |
| Serverless | Free | 2 | +$0/month, 2 more features |
What each tier adds
The set difference between each tier's feature list and the one beneath it. Where a tier lists nothing new, the vendor has either stopped repeating the inherited list or the tier raises limits rather than adding capability, the record does not distinguish the two, so this page does not either.
Open Source
FreeThe entry tier. It covers full features, self-hosted.
Serverless
FreeOver Open Source, this tier adds:
- Managed service
- Auto-scaling
Where Weaviate stops being free
Open Source, Free
- Full features
- Self-hosted
No paid tier on record
Weaviate lists a free tier and no priced tier above it in the record we hold.

How that compares in Machine Learning
Too few machine learning tools in this directory publish a starting price to quote a meaningful median, so the table below is a like-for-like list rather than a ranking.

| ClearML | Free | Open-source self-hosted, with paid hosted and enterprise tiers | - | vs Weaviate |
| Langwatch | Free, then €29/month | Tiered subscription with usage-based overage charges | - | vs Weaviate |
| Haystack | Free | Open-source with optional paid enterprise support | - | vs Weaviate |
| Semantic Kernel | Free | Open source, no pricing | - | vs Weaviate |
| Fal AI | $1.89/hour | usage-based | - | vs Weaviate |

Ratings are aggregated from third-party sources and imported with each catalogue entry, they are not reviews hosted on Softwr. How each figure is used is set out on the Weaviate badges page.
Before you pay for Weaviate
Three things this page cannot tell you, and all three change the bill. The record carries a price and a billing period but not the unit - per-seat and flat-rate pricing are indistinguishable in this data, so a five-person team may be looking at five times the figure above. It carries no annual rate, so any discount for paying yearly is not something this page can quote. And it carries no trial length.
What it can tell you is the shape of the ladder: 2 tiers between Free and Free, with the jump itemised above. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.
Weaviate runs on linux, mac, windows, web, and is published by Weaviate of Amsterdam, Netherlands. The full record is on the Weaviate review, and the rest of the category is under best machine learning tools.
