Read-only by design

Optimize measures your workbooks over the Tableau REST API and never changes anything on its own. Every change is proposed as a card, dry-run first, and applied only after your explicit approval.

Connect to Tableau

Sign in with a Personal Access Token to run the Workbook Optimizer against your published workbooks. Reads only: nothing changes without your explicit action.

Optimize Workbook Performance

Browse the site inventory, then run the Workbook Optimizer on any workbook you published. Deterministic fixes publish as an _OPTIMIZED copy; everything else stays a design decision.

Site inventory

Workbooks on the connected site, with size, views and last update. Select a workbook to run the Workbook Optimizer against it.

Reading the site inventory…

Workbook Optimizer

The same twenty guidelines Tableau's Web Authoring Optimizer checks, evaluated against the workbook you actually published. Results land in your saved optimization runs.

Workbook preview

Select a workbook in the inventory to preview it before measuring.

Optimization console
Ready. Run the Workbook Optimizer to assess the selected workbook.
Your saved optimization runs

No saved runs yet. Finished analyses land here automatically.

Run the Workbook Optimizer and the assessment lands here, rule by rule.

Evaluated locally on your own session: Tableau exposes no API for the Web Authoring Optimizer, so the workbook is downloaded with your PAT and checked against Tableau's published guidelines. Every finding shows the measured value.
