Best 8 active metadata management tools
For organizations to use AI for their analytics needs, the role of metadata management has shifted from back-office hygiene to mission-critical infrastructure. Metadata is no longer just about cataloging data products, it’s about enabling AI to understand your data. Using metadata management you can declutter your data analytics, ensure that you’ve “certified” dashboards for their AI-readiness and align your metrics so that AI agents can deliver trusted results, every time.
In this post, we’ll review some of the most powerful metadata management platforms available in 2025, with a focus on tools that help make your data AI-ready, discoverable, and governed at scale.
What are metadata management tools?
As more companies invest in AI and data-driven decision making, the importance of metadata has grown. Metadata essentially tells you what a dataset means, where it came from, how it’s used, and who owns it. When managed properly, metadata helps you certify data assets for AI use (for example making sure it uses the agreed definition of “ARR”, “DAUs”, “CAC” etc) trust it, and use it to power AI-based data analytics. After all, if the data is flawed, ai-based data analytics won’t work.
With the explosion of data sources, formats, and users, manual approaches to tracking metadata no longer work. That’s where modern metadata platforms come in. These tools help teams automatically collect, organize, and enrich metadata so they can better understand and manage their data assets.
Here are some of the top metadata management tools available in 2025:
Best 8 active metadata management tools
1. Euno
Website: euno.ai
Euno is built for data teams who want to activate their metadata, not just document it. It connects lineage, usage, code, and ownership, so you can see how data flows, what’s trusted, and what needs to go. It also powers an MCP server that gives AI agents access to governance signals like certification status and metric definitions, so they stop guessing and start acting with context.
Euno’s core use cases:
- Dashboard certification: Set your own certification rules—based on lineage, SQL logic, ownership, etc.—and enforce them at scale. Euno surfaces what violates the rules and tells you exactly how to fix it.
- Metrics governance: Manage a source of truth for metrics. Find the most-used business terms in your BI layer, resolve conflicting definitions, and move what matters into a governed semantic model.
- Decluttering & cost control: Automatically flag stale dashboards, unused refresh jobs, and idle models. Clean up the noise and cut compute costs in the process.
