OpenMetadata Pricing: Is It Really Free? The Real Cost Explained

OpenMetadata is free to license, and that is the one fact about its cost that misleads buyers. Yes, the software is open source under Apache 2.0, with no license fee, so you can download it and run it for free. But running it in production is not free, and "free software" is a different thing from "free to operate." The question that matters for a budget is not whether OpenMetadata is free; it is what it actually costs to run.

This guide separates the two things teams confuse: the price of the software (free) and the total cost of operating it (engineering, infrastructure, and maintenance). It also covers Collate, the managed cloud service from the company behind OpenMetadata, including its free tier and how its paid pricing works.

Is OpenMetadata Free?

Yes, the software is, which is also the least useful answer. OpenMetadata is Apache 2.0 with no per-user license, no edition tiers, and no paywalled core, so the project itself costs nothing to download and self-host. The catch is everything required to turn that software into a running, reliable service, and that is where the real cost lives.

A data catalog is not a desktop app you install once; it is a set of always-on services that ingest metadata on a schedule, index it for search, and serve it to users. Standing those up and keeping them healthy is ongoing engineering work, not a one-time setup.

The Real Cost of Self-Hosting

Self-hosting OpenMetadata means your team owns the full stack. The recurring costs fall into three buckets.

Cloud infrastructure. OpenMetadata runs the metadata server, a relational database (MySQL or PostgreSQL), and a search index (Elasticsearch or OpenSearch), plus the ingestion jobs. Each needs compute and storage, sized for your metadata volume and your uptime expectations. For a production deployment with high availability, infrastructure is a real monthly line item, even if it is modest compared to a warehouse bill.

Engineering time to deploy and integrate. The initial work of deploying the platform, configuring connectors for your sources, wiring up authentication, and validating ingestion is a project, not an afternoon. This is upfront engineering cost measured in person-weeks.

Ongoing maintenance and ownership. This is the cost teams underestimate most. Someone has to handle version upgrades, security patches, backups, monitoring, and incidents, and to keep connectors working as source systems change. Open-source data catalogs move quickly, so staying current is continuous work. Over a year, this internal ownership often outweighs the infrastructure bill.

None of these are license fees, which is why "free" is technically accurate and practically misleading. The honest framing is total cost of ownership: free software plus paid people and infrastructure.

Collate: Managed OpenMetadata Pricing

Collate is the commercial company founded by OpenMetadata's creators. It offers a fully managed cloud version of the platform, so you get OpenMetadata's capabilities without running the infrastructure yourself. Collate handles installation, updates, upgrades, backups, encryption, and high availability, and adds enhancements on top of the open-source core.

On pricing, Collate follows the enterprise software pattern rather than publishing a fixed per-seat price list. Paid managed plans and enterprise support are arranged through sales, with deployment options and private contracts available, and listings are also offered through cloud marketplaces such as AWS Marketplace. In practice this means you contact Collate for a quote based on your scale and requirements, rather than reading a price off a page.

The value proposition is straightforward: you trade the engineering and operational cost of self-hosting for a subscription, and in return you remove the ownership burden. Whether that trade is worth it depends on whether your team would rather pay people to run OpenMetadata or pay a vendor to run it for them.

The Collate Free Tier

Collate offers a free tier aimed at teams who want to get started without a contract. It includes the core open-source features of OpenMetadata plus enhancements such as cost analysis, a knowledge center, and metadata automations, all delivered as a managed service.

The one operational detail to plan around: inactive clusters are reclaimed after four weeks of inactivity. The free tier is built for evaluation and getting started, not as a guaranteed-permanent production environment, so a project that goes quiet for a month may need to be re-provisioned. For a proof of concept or an initial trial, it is a fast way to see managed OpenMetadata without standing up your own infrastructure.

Which Option Fits

Three realistic paths, each with a different cost shape:

• Self-host the open-source project. Zero license cost, but you pay in infrastructure and engineering. Best for teams with platform engineering capacity who want full control and an open, extensible system.
• Collate managed (free tier). No infrastructure to run, good for evaluation, with the four-week inactivity reclaim to keep in mind. Best for proofs of concept and early trials.
• Collate managed (paid). A subscription that removes operational work, priced through sales. Best for teams that want managed OpenMetadata in production without owning operations.

The decision is rarely about the license, since that is free either way. It is about where you want to spend: on your own engineers and infrastructure, or on a managed subscription.

How Dawiso Compares on Total Cost

Dawiso approaches the same problem with a managed, business-friendly model and transparent pricing. The relevant comparison is not license versus license, since OpenMetadata's license is free; it is total cost of ownership and time to value.

With a self-hosted open-source catalog, the recurring spend is your platform team plus infrastructure, and the timeline to adoption depends on how fast that team can deploy, integrate, and then drive usage among business users. With Dawiso, the platform is delivered as a service, so there is no infrastructure to own, and the product is designed for fast adoption by non-technical users through a business glossary and data catalog built for them, not just for engineers. Governed context is also served to AI agents through the Model Context Protocol (MCP), which extends the catalog's value beyond human users.

The honest summary: OpenMetadata can be the lower-cost option for engineering-led teams who already run platform infrastructure, while a managed catalog like Dawiso often wins on total cost once you account for the people and time required to operate open source and to drive adoption.

Conclusion

OpenMetadata's pricing question has a simple answer and a useful one. The simple answer: the software is free under Apache 2.0. The useful answer: running it in production costs real money in infrastructure and engineering, and the managed alternative, Collate, trades that operational cost for a subscription priced through sales, with a free tier for getting started. Budget for total cost of ownership, not the license, and weigh self-hosting against managed options before deciding. For the platform itself, see what OpenMetadata is.
