Overview

DataHub brings technical metadata, business knowledge and documentation together so teams can find data assets and understand their relationships. Metadata discovery, a business glossary and lineage analysis make it relevant to organisations trying to connect technical catalogs with business meaning and AI workflows.

Core and Cloud address different operating preferences: Core is open source and self-hosted, while Cloud is a managed enterprise service. Core’s no-cost entry point comes with meaningful operational and access-control responsibilities, so it is best for teams equipped to run the platform themselves.

DataHub sits in Metadata Management Software. It supports API, Linux, self-hosted and web use.

Key features

Discovery and AI connections

Cloud combines natural-language search, smart ranking and an Ask DataHub chat agent with a hosted MCP server that connects AI tools to the catalog. The maker says it has more than 100 pre-built connectors and native integrations including Slack, Microsoft Teams, Chrome and BI tools. MCP-native integrations include Cortex, Genie, Cursor, Claude, LangChain, Agent Development Kit, CrewAI and custom agents. That breadth is useful when teams want catalog context to reach collaboration, analytics and AI tools, though these Cloud discovery capabilities do not make Core equivalent to the managed service.

Observability and lineage

Automated checks cover schema, freshness, volume and custom quality rules, alongside AI anomaly detection and incident workflows. These features give data teams ways to detect and manage issues rather than treating the catalog as a static inventory. Cross-platform, column-level lineage follows data from source through transformations and AI models to downstream assets, helping teams understand dependencies when investigating changes or tracing usage.

Security and service

Cloud is described as SOC 2 compliant, with role-based and attribute-based access controls and an in-VPC remote execution option for sensitive sources. DataHub says it encrypts customer data at rest and in transit and conducts third-party penetration tests and static security analysis. Cloud is fully managed with SLA-backed 99.5% availability, onboarding and adoption support, a dedicated customer success team and private Slack support. Core instead provides basic access controls, community Slack and self-service documentation; it has no SSO or fine-grained permissions out of the box. That gap makes Cloud the more appropriate choice where those access controls matter.

Pricing

DataHub Core

0.00 USD per free, billed Free to deploy; open source. Core is self-hosted and includes manual installation, configuration, upgrades, uptime and troubleshooting, with basic access controls and community support. It fits teams able to take on that work and accept the lack of built-in SSO and fine-grained permissions. The zero-cost plan’s trade-off is operational ownership, not merely a smaller feature bundle.

DataHub Cloud

Custom pricing, scoped to data volume, users and selected capabilities; contact sales. Cloud is managed enterprise SaaS, with pricing shaped around the use case and data environment. It is the better fit for teams seeking managed operations, Cloud’s discovery features, stronger access controls and included onboarding and support. A Google Cloud offer advertises a 21-day trial with a dedicated instance and full platform access.

Platforms

DataHub supports API, Linux, self-hosted and web platforms. Core is self-hosted; Cloud is managed enterprise SaaS. The choice is therefore not just about where users access the catalog, but whether the team wants to operate the service itself.

Who it's for

DataHub is strongest for enterprise data teams that need metadata discovery, a business glossary and lineage across data systems, and that want catalog context connected to observability and AI workflows. Core suits teams with the capacity to manage installation, upgrades and uptime, and whose access-control needs fit its basic controls. Cloud better serves teams that need managed availability, SSO-free? no: Core has no SSO, so Cloud is preferable when stronger role- and attribute-based controls are needed, as well as onboarding and dedicated support.

Pros and cons

Pro: Discovery, glossary and cross-platform column-level lineage bring asset context and dependencies together, including paths through AI models.
Pro: Cloud combines more than 100 pre-built connectors with observability checks, anomaly detection and incident workflows.
Pro: Free, open-source Core gives self-hosting teams a no-cost way to deploy the platform.
Con: Core requires teams to handle installation, upgrades, uptime and troubleshooting, and lacks SSO and fine-grained permissions out of the box.
Con: Cloud pricing varies with data volume, users and capabilities, so buyers must obtain a use-case-specific price.
Con: Core’s basic access controls make it a poor fit where more granular permissions or SSO are required.

Alternatives

Progress Semaphore is a paid option with a trial and a development plan for demos, development and capability evaluation; consider it when that plan structure better matches evaluation needs.

Ab Initio Data Platform is a paid alternative that requires a free proof of concept before purchase, making it a fit for buyers who want that step before committing.

Aurelius Atlas offers a free, open-source self-hosted plan with optional consulting, so it is worth considering when a no-license-cost self-hosted option is the priority.

MetaKarta is a paid alternative whose Data Lineage Starter plan costs 50.00 USD per year and caps usage at five concurrent users and five pre-selected connectors; it may suit smaller, tightly bounded lineage needs.

Dawiso starts at 445.00 EUR per month for Standard, with five user seats, five contributor licenses, 20 viewer licenses and unlimited connectors. Consider it when those stated seat counts and unlimited connectors align with the team’s needs.

Alation Data Intelligence Platform uses a pool of consumption units for AI capabilities, with the pool size estimated with Alation; it may suit buyers seeking that AI-capability model.

Aristotle Metadata Registry has paid Micro and Secure hosting plans; a reader comparing metadata registry options may want to consider it.

SemanticWorx Affirma offers paid, inquiry-priced annual subscription plans; it is another option for buyers comparing custom-priced software.

Verdict

Choose DataHub if your team needs a connected catalog, lineage and observability for enterprise data and AI, and can match the deployment model to its operational capacity. Core’s free self-hosting is compelling for capable operators, while Cloud is the stronger choice for managed availability, access controls and support. Look elsewhere if Core’s control limits are unacceptable and Cloud’s use-case-based pricing is not a fit.
