How to Build a SaaS Analytics Dashboard in Bubble.io
A dashboard that computes metrics at render time is always slow. A dashboard that reads pre-computed values is always fast. This guide covers the denormalisation strategy, chart plugins, and performance patterns for production SaaS dashboards in Bubble.
The Right Way to Build Dashboards in Bubble
A dashboard that runs six count queries, four sum queries, and three chart data queries on every page load will feel painfully slow. A dashboard that reads six pre-computed numbers from a single Workspace record will load in milliseconds. The entire philosophy of Bubble dashboard architecture is: compute expensive aggregations once when data changes, store the results, and read those stored results at render time. Never compute at render time.
Which Metrics to Denormalise
| Metric | Store On | Update Trigger | Update Action |
|---|---|---|---|
| Total records count | Workspace | Create / soft delete any record | record_count + 1 or – 1 |
| Active members | Workspace | Membership status change | seats_used + 1 or – 1 |
| Monthly revenue | Workspace | Stripe invoice.payment_succeeded webhook | mrr = invoice amount |
| Completed tasks this week | User | Task marked complete | weekly_completions + 1 |
| Conversion rate | Workspace | Daily scheduled workflow recalculates | converted / total * 100 |
| Average response time | Workspace | Rolling window — computed daily | Scheduled overnight recalc |
For Metrics That Can’t Be Fully Denormalised
// Strategy: compute on page load but cache in custom state
Page load workflow:
Step 1: Search for Orders [workspace=current, created > 30 days ago]:sum of amount
Step 2: Set custom state “revenue_30d” = Step 1 result
Step 3: Text element displays “revenue_30d” state — not the live query
// This fires once at page load — not on every element render
// Add a “Refresh” button that re-runs the page load workflow if needed
Charts in Bubble — The Right Plugins
Chart.js Plugin
The most capable free chart plugin for Bubble. Supports line, bar, pie, doughnut, radar, and mixed charts. Pass data as a list of numbers and labels. Customisable colours, tooltips, and animations.
Apexcharts Plugin
More modern design than Chart.js. Excellent for time-series line charts, area charts, and heatmaps. Responsive by default. The preferred choice for SaaS dashboards in 2026.
Metric Cards (Custom)
For single-number KPI cards (MRR, DAU, Churn), build reusable elements with a large number, a label, and a trend indicator (up arrow in green, down in red). Display the pre-computed Workspace field value.
Progress Bars
For usage meters (seats used / seat limit), a simple styled shape works best. Width as percentage: seats_used / seat_limit * 100%. Colour conditioned on percentage: green below 70%, amber 70–90%, red above 90%.
Data Tables
Repeating groups styled as tables — header row as a non-repeating row of column headers, data rows as the RG cells. Use consistent column widths, alternating row colours, and sortable column headers.
Export to CSV
Every data table should have a CSV export button. Use the Toolbox plugin or a backend workflow to generate the CSV content, store as a file, and trigger a download. Enterprise customers always ask for export.
