Refine vs React-Admin vs AdminJS: the open-source admin panel for a Next.js SaaS (2026)

The quick answer (2026)

If you are bolting an admin panel onto a Next.js SaaS in 2026, the whole decision comes down to one question: how much of the interface do you want to own, and where does it run?

• 

  Refine is a headless React framework. You bring your own UI (or plug in Ant Design, Material UI, Mantine, or a custom Tailwind kit) and it lives inside your existing Next.js app. Most flexible, best Next.js fit, most decisions to make.

• 

  React-Admin is an opinionated single-page app framework locked to Material UI. Fastest way to a complete CRUD back office if you accept its look, but it ships as its own client-side SPA and its premium modules sit behind a paid Enterprise Edition.

• 

  AdminJS auto-generates a whole admin panel from your database models. Almost no UI code, but it mounts on a Node.js/Express server, which is an awkward fit next to a serverless Next.js deploy.

We road-test these building blocks so we can own the stack that funds the life, not chase the newest logo. Here is how the three actually differ once you get past the marketing.

The one decision that actually matters: where the panel lives

Most listicles rank these three on feature checklists. That buries the real fork. For a Next.js SaaS, the deciding difference is architecture, not feature count.

Refine is a framework you compose inside your app. It gives you data hooks, auth, routing helpers, and a resource model, then gets out of the way on the UI. Because it is headless, it drops into the Next.js App Router and you style it with whatever you already use. That is why our hands-on Refine v5 starter review landed it as the most flexible option we tested: it is the only one of the three that feels like part of your Next.js codebase rather than a bolted-on service.

React-Admin is a finished SPA you configure. It is a React client-side application built on Material UI that talks to your REST or GraphQL API. You describe resources and it renders a complete back office fast. The trade is that it is a separate SPA. You can host it on a Next.js route, but it does not use server components, and the Material UI look is baked in deep enough that fully rebranding it is real work.

AdminJS is a panel that writes itself from your data. You point it at your Prisma, TypeORM, Sequelize, or Mongoose models and it generates CRUD screens automatically, in the spirit of Django Admin. The least code by far. But AdminJS mounts on a persistent Node.js server through an Express, Nest, Fastify, or Hapi adapter, so in a serverless-first Next.js project you are running a second stateful service just for the admin.

Refine: own the UI, live inside Next.js

Refine describes itself as "a React framework for building internal tools, admin panels, dashboards and B2B apps with unmatched flexibility," and that is an honest summary. The core (@refinedev/core, v5.0.12 in 2026) is MIT-licensed with no feature paywall.

Deploy path: scaffold with npm create refine-app, build it into your Next.js app, and deploy on Vercel, Netlify, or anywhere your app already goes. Nothing extra to host.

Cost: free to self-host. Refine also sells an optional AI agent product, but the framework itself carries no gated modules.

Where it loses: flexibility is a tax. Headless means you assemble more, so time-to-first-screen is slower than AdminJS, and beginners can feel lost choosing a UI layer. If you want a back office generated for you today, Refine will feel like homework.

React-Admin: the fastest complete back office, if you accept Material UI

Marmelab's React-Admin (v5.15.1 in 2026, 26.9k stars, MIT core) is the quickest route to a polished, feature-rich CRUD admin. Lists, filters, forms, references, and optimistic UI come out of the box.

Deploy path: scaffold with create-react-admin, build a static SPA bundle, and deploy it on any static host or a Next.js route.

Cost: the core is genuinely free and MIT. The catch is the Enterprise Edition, a paid subscription (Team is 145 euro per month for up to 2 developers, Business 290 euro per month, Corporate from 590 euro per month, per Marmelab's 2026 pricing) that gates the modules teams eventually want: role-based access control, audit log, realtime updates, an editable AG-style datagrid, and an AI assistant. You can ship a lot without paying, but the enterprise-grade polish has a price tag.

Where it loses: Material UI lock-in. If your product has its own design language, matching it in React-Admin is a fight, and the RBAC and audit features most SaaS admins need eventually live behind the subscription.

AdminJS: least UI code, but it wants a server

AdminJS (v7.8.17, 9.0k stars, MIT) is "an admin panel for apps written in node.js." Give it your ORM models and it renders a full CRUD interface with almost no code, plus custom actions and dashboard widgets.

Deploy path: mount it on an Express, Nest, Fastify, or Hapi server and deploy on Render, Railway, Fly, or a VPS. It needs a long-running Node process, so it is not a natural fit for static or serverless targets.

Cost: fully free and MIT, no enterprise tier to buy. That is a real advantage over React-Admin if budget is the constraint.

Where it loses: two honest marks. First, the serverless mismatch above. Second, momentum: the most recent AdminJS release was July 2025, roughly a year before this writing, and at 9.0k stars its ecosystem is a fraction of the other two. It is stable and useful, but it is not moving as fast, and its UI is harder to bend to a custom brand than Refine's headless approach.

How to pick

• You want the admin to feel like part of your Next.js app and you will style it yourself: choose Refine. It is the only one that treats your Next.js codebase as home.
• You want a complete, feature-rich back office this afternoon and Material UI is fine: choose React-Admin, and budget for the Enterprise Edition once you need RBAC or audit logs.
• You want CRUD generated straight from your database models with almost no UI work and you can run a Node server: choose AdminJS, as long as a separate stateful service does not break your serverless deploy.

There is no universal winner here, which is exactly why "best admin panel" listicles are useless. The right pick falls out of your deploy target and how much UI you are willing to own. For where each of these sits against the wider stack, our open-source Next.js SaaS starter scorecard tracks the full field.

Your move: match the tool to your deploy target first, the feature list second, and you will not have to migrate your admin panel twice.
