How much does MLflow cost?

MLflow publishes a single tier, Open Source, at Free.

Does MLflow have a free plan?

Yes. The Open Source tier costs nothing and covers experiment tracking, model registry, deployment tools.

Which machine learning tools can I use without paying?

7 of the 8 machine learning tools listed alongside MLflow have a free tier: ClearML, Langwatch, Haystack, Semantic Kernel, H2O.ai.

What am I actually paying for with MLflow?

The record lists 13 features across 3 areas: other, integrations, platform. In practice it is brought in for machine learning, data analysis, model training.

Does MLflow charge per user?

The record carries a price and a billing period for each of its 1 tiers, but not the unit that price is charged in. Per-seat and flat-rate billing look identical in this data, so check the vendor's page before budgeting for a team.

Are these MLflow prices current?

They are what the catalogue entry holds, refreshed when the entry is. Vendors change pricing without notice and nobody at Softwr re-verifies each tier by hand, so treat this as a structured summary and the vendor's own pricing page as the authority.

What should I compare MLflow against before paying?

The closest machine learning tools in this directory are ClearML, Langwatch, Haystack, Semantic Kernel. Each has a side-by-side comparison with MLflow covering price, platforms and features.

MLflow 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.

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.

Tool	Entry price	Model	Rated	Head to head
MLflow (this page)	Free	open-source	-
ClearML	Free	Open-source self-hosted, with paid hosted and enterprise tiers	-	vs MLflow
Langwatch	Free, then €29/month	Tiered subscription with usage-based overage charges	-	vs MLflow

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 MLflow badges page.

Before you pay for MLflow

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: a single tier at Free. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.

MLflow runs on web, python api, rest api, and is published by Databricks of San Francisco, California. The full record is on the MLflow review, and the rest of the category is under best machine learning tools.
