HTML Dashboard Development

When the dashboard needs to live inside your product or customer portal, look like your brand, and skip per-user BI licences.

There's a point where a BI tool stops being the right container. You need analytics inside your own application, styled to your brand, with interactions the tool doesn't support, served to hundreds of external users who shouldn't each need a licence.

We build those as proper web applications — React on the front end, D3 or a charting library for the visuals, a well-designed API behind it, and authentication tied to your existing identity provider. Performance and accessibility are treated as requirements, not afterthoughts.

This is a heavier build than a Power BI report, so we're honest about when it's justified: customer-facing analytics, embedded product features, or highly custom interactions.

Problems this solves

What we usually walk into

  • Customers need analytics but you can't licence every one of them in a BI tool.
  • Embedded BI iframes don't match your product's look or interaction model.
  • You need a visualization the BI tool simply cannot render.
  • Mobile users get a desktop dashboard squeezed onto a phone.

Challenge

Customers asked for analytics inside the product. Embedding a BI tool would have meant per-customer licensing and an iframe that visibly clashed with the product's design.

Solution

A React and D3 analytics module inside the existing application, backed by aggregation endpoints with tenant isolation enforced in the API layer, using the product's own design tokens.

Result

Analytics shipped as a paid tier feature with no per-user licensing, and pages render in about a second at the 95th percentile.

FAQs

Questions we get asked

Why not embed Power BI?
Embedding is cheaper and faster when the look and interactions are acceptable. Custom wins on branding, unusual interactions, and external-user economics.
Who hosts it?
You do, in your cloud. We deploy into your accounts and hand over the pipeline.
Can it handle large datasets?
Yes — through server-side aggregation and windowed queries. The browser only ever receives what it renders.
Is it accessible?
We build to WCAG 2.1 AA: keyboard navigation, screen-reader labelling on charts, and data tables as an alternative view.
