PlanckUi vs Elfsight: free vs $15–40/month
Elfsight is a solid product — and a solid monthly bill. If you just need a testimonial wall, a form or a review widget on your website, here is the honest side-by-side.
| What matters | PlanckUi | Elfsight |
|---|---|---|
| Price | $0 — every widget, forever | $15–40+/month for most usable widgets |
| Signup required | No — copy the HTML and go | Yes — account + widget builder |
| Watermark | Never | Removed on paid plans |
| Widget catalog | 590+ (testimonials, forms, docks, social, commerce) | 200+ (largest paid catalog) |
| Customization | Full editor: colors, fonts, radius, shadows, dark mode | Per-widget editors, deeper on higher tiers |
| Pageviews limit | Unlimited | Capped per plan, overage = upgrade |
| How it embeds | Self-contained HTML snippet or script tag | Script tag, per-widget |
| Native Mac app | Yes — SwiftUI dock for your desktop | No |
Where Elfsight wins
Elfsight has more integrations, deeper per-widget settings, and a mature dashboard. If you need a specific niche integration and already pay for it, there is no reason to leave.
Where PlanckUi wins
Price is the obvious one — but the deeper difference is the flow. Elfsight’s widgets live in their cloud behind an account and a per-view plan. PlanckUi widgets are self-contained HTML you copy and own: paste once, works forever, renders on your visitor’s browser with no calls to our servers. No pageview meter, no surprise upgrade prompt when your traffic grows.
You also get a full library beyond testimonials — forms, social cards, platform-branded embeds with real logos, macOS-style docks, and 590+ more — all under the same $0.
Try it in 60 seconds
Open the testimonial widgets, paint one to match your site, copy the HTML, paste it where Elfsight’s widget would go. If you don’t like it, you’ve lost a minute — not a monthly subscription.
