VPAX Analyzer — see what your model costs in memory.
A .vpax file holds the VertiPaq statistics of a Power BI semantic model: the size, cardinality and encoding of every column, the row count of every table, and the relationships. This page reads one in your browser and shows where the memory actually goes, which columns make up 80 % of the model, and which findings the statistics prove — unreferenced heavy columns, near-unique columns, referential-integrity violations, expensive text keys. Nothing is uploaded and no account is needed.
Export the VertiPaq statistics from DAX Studio (Advanced → View Metrics → Export as .vpax) or Tabular Editor, drop the file here: model size, the columns that make 80 % of it, cardinality and encoding, referential-integrity violations, and what a fix would save.

What it reads: DaxVpaView.json inside the .vpax — sizes, cardinalities, encodings, relationships.
What it cannot see: which columns the report uses. The full audit joins both.
Privacy: a .vpax holds metadata and statistics, never row values. It is parsed in your browser and not uploaded.
