React UI blocks, $2.7K in 30 days: reusable components

Efferd is a library of structured React interface blocks that developers can adapt and install. Its $2.7K in the last 30 days is verified through the payment provider's API by TrustMRR (Polar), as of September 30, 2026.

What it actually sells

Efferd sells a library of ready-to-use shadcn/ui blocks for React projects. The blocks are designed to be structured and rewritten until they feel like the user’s own. One example is an auth block installed through the shadcn registry with `npx shadcn@latest add @efferd/auth-1`.

The library works with any React framework and supports both Radix UI and Base UI foundations. Developers can switch between icon libraries. Pro includes all Pro blocks, lifetime updates, a commercial license, and priority support.

How it charges

The official site shows its pricing as follows: Hobby: Free. PRO: $147 (previously $249), one-time payment. TEAM: $497 (previously $899), one-time payment. Prices are as shown on the site on 2026-10-01 and may change.

One launch account says the first sale came in under five minutes after the founder posted on X.

Where it sits in the data

Efferd's $2.7K in the last 30 days is higher than 85% of the 5,602 projects with payment-verified revenue in our dataset; the median across them is $150. Within the “Design Tools” category (452 projects) it is higher than 92% (category median $118). Snapshot: 2026-09-02 to 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

In my view, this is a focused developer-tool business with a clear buyer: React developers who need interface blocks for personal work or client projects. Distribution would come from search, direct promotion on X, and the visible open-source library, with a separate paid Pro version.

The hard part is not only assembling compatible components. It requires keeping implementations coherent across React frameworks, UI foundations, icon packages, installation commands, documentation, updates, licensing, and support. Competition and distribution matter because developers can compare libraries directly and choose whether to adapt or build components themselves.

Verdict: Needs real work.

One thing to take from it

The clearest lesson is to package a reusable technical asset in a form developers can inspect, install, and adapt. Efferd presents an open-source library alongside a paid Pro version, with its product organized around framework compatibility, UI foundations, icon choice, and client-project use.
