Building 4 UI Template Kits: What Actually Saves Developers Time

Over the past few weeks I packaged UI patterns into template kits for four different product types: a SaaS dashboard, an e-commerce checkout flow, a fintech mobile app, and an enterprise design system.

I'll be honest — I started this project thinking "templates are easy, everyone needs them." Building them properly taught me something else: the value is not in the fancy parts. It's in the boring 80%.

Here's what I learned for each kit.

1. SaaS dashboards: the table is the product

Everyone demos the charts. But in real use, 80% of a dashboard is data tables: sorting, filtering, pagination, empty states, loading skeletons.

Patterns that actually save time:

• One table component with three modes (simple, sortable, filterable) instead of three components
• Charts as thin wrappers around Chart.js — the value is in the defaults (colors, spacing, tooltips), not the wrapper
• Dark mode as a token swap, not a re-skin. If you're writing .dark overrides by hand, your tokens are wrong

That's why the SaaS Dashboard Starter Kit ($29, React + Next.js + Tailwind) ships 15+ components but is really about the table, the chart defaults, and the dark/light token system.

2. E-commerce checkout: trust is a UI feature

Checkout flows don't fail because of broken forms. They fail because users don't feel safe.

Things that move conversion (and are mostly pure UI):

• Progressive disclosure — show only the steps that matter, one at a time
• Trust badges near the payment step, not buried in the footer
• Error messages that say what to do next, not "invalid input"
• A/B-tested layout variants baked in so you can test without redeploying

The E-commerce Checkout Flow kit ($34, Vue 3 + Nuxt) is built around the multi-step wizard, a Stripe/PayPal-ready payment form, and HTML + MJML email templates.

3. Fintech mobile: safe areas decide the feel

Mobile banking apps live or die on small details:

• Safe area handling for notched devices (the camera cutout will eat your balance otherwise)
• Biometric auth flows that feel instant — the loading state is the trust signal
• Number typography — tabular figures for amounts, or your tables will jitter
• 60fps animations on money movements — anything slower feels like the app is "thinking" about your balance

The Fintech Mobile App UI ($39, React Native + Expo) covers account overview, transactions, card management, and the biometric auth flow for both iOS and Android.

4. Design systems: tokens first, components second

Every failed design system I've seen started with components. The ones that work start with tokens:

• JSON + CSS variables as the single source of truth
• Figma-to-code sync scripts so designers and engineers stop copy-pasting hex values
• Contrast checking in CI — accessibility debt is design debt
• A typography scale generator instead of "we'll figure out the sizes"

The Enterprise Design System Starter ($49) is the token system + component library structure + Figma sync, with 192 color palettes and 74 font pairings included.

On pricing

I priced them by dev time saved, not by file count: $29–$49 against 3 days to 3 weeks of work. If a kit saves you one day of boilerplate, it pays for itself.

What's next

I'm planning a fifth kit based on the most-requested pattern in the comments of my launch posts.

What UI pattern do you wish existed out of the box? Tell me in the comments — it might end up in the next kit.
