The Apache-2.0 OpenMetadata edition is free to license, but self-hosting it is a multi-service stack - database, search, server, and an Airflow ingestion workflow - that your team starts in dependency order, patches, scales, and migrates on every upgrade, where docs strongly recommend backing up metadata first. Analyst comparisons peg self-hosted open-source catalogs at roughly 3-6 months to production value and a standing 0.5-1 FTE to maintain. Dawiso is fully managed in every deployment option - SaaS, your Azure tenant, or on-prem - so there is no infra to run and time-to-value is 2-4 weeks. The AI and automation features many teams want from OpenMetadata - AskCollate, AI Agents, Reverse Metadata, Service Insights - are gated to the paid Collate Cloud, whereas Dawiso ships its Technical Writer Agent and read+write MCP Server in every plan.
