The #1 data lineage & governance tool for Power BI and Microsoft Fabric. Trace any column from the database to the visual, govern your entire tenant, and optimize your models with confidence.
One PostgreSQL column, followed the whole way down.
Expand a source server down to a single column, then keep going into every semantic model that reads it, each model column flagged used or unused, and on to the relationships, visuals and filters that consume it.

Follow any column or measure from a shared semantic model to every report, page and visual that uses it, across the whole Power BI Service.
Same connection, broader scope. Scan your whole tenant and answer the questions IT, security and finance keep asking: who owns what, who has access to what, what is actually being used and what it costs. Tenant analysis docs →
Trace a single column from a source table through every dataflow, semantic model and report, all the way to the individual visual that renders it. When a semantic model imports from yours through the Analysis Services connector, the trail keeps going, so you see which parts of your model other teams build on. End-to-end. No gaps. Nobody else does this.
Copilot in Power BI, Microsoft Fabric Data Agent and every BI Q&A tool are only as good as the model behind them. Three high-leverage cleanups before you turn AI loose on your tenant.
Unused columns inflate the model the AI has to index. Unused measures get suggested as answers nobody intended. Unused tables muddy the lineage the AI is supposed to follow. Measure Killer finds and removes them — at tenant scale, with impact analysis so nothing breaks.
Decommissioned reports and stale pages get suggested by Copilot alongside the ones your team actually uses. Measure Killer surfaces views per report and per page so you can archive the dead weight — Copilot only sees what's alive and worth your team's attention.
Cryptic field names, undocumented measures, missing descriptions and anti-patterns all degrade AI suggestions. The best-practice analysis runs across every model and report in your tenant — fix the worst violations once and every AI tool gets better overnight.
Measure Killer's tenant exports are the richest Power BI metadata you can get anywhere — every DAX expression, every M query, column-level lineage, refresh events, best-practice violations, used vs. unused columns and measures, page-level consumption with average load times, and now capacity cost. Feed that to a frontier AI model and you get prioritized optimization suggestions ranked by real financial and performance impact — not generic best-practice noise.
Lineage is only trustworthy if every reference is found. Measure Killer traces each one — down to a tooltip, a conditional-formatting rule, or a measure nested inside another measure — so you see the full downstream impact before you rename, move or remove anything. At 99.99% reference-detection accuracy (the best in the industry), that's the difference between a confident change and a quiet outage. The handful of edge cases that can still slip through are listed transparently.
