Remix is now React RouterSame loaders and actions, new package name
The Remix Supabase SaaS boilerplate, continued on React Router 8
Remix v2 merged into React Router, and this kit moved with it. Imports change from @remix-run/* to react-router. Routes are declared in routes.ts, with loader and action types generated per route.
Authentication
Sign-in your users already expect
Password, magic link, passkeys, OAuth and multi-factor authentication, with the emails that go with them.
Transactional emails
Templates written in JSX with React Email, sent through Resend or Nodemailer (SMTP).
Every sign-in method
Password, magic link and social sign-in, configured per environment.
Passkeys
Opt-in sign-in with Face ID, Touch ID, Windows Hello or a security key. No password to phish.
Magic links
Passwordless sign-in: users get a one-time link by email instead of typing a password.
Accounts and billing
Everything a multi-tenant B2B SaaS needs
The multi-tenant SaaS boilerplate parts: auth, billing, teams with roles, and a super admin that can impersonate or ban users and teams, plus the screens your customers use to manage them.
Roles and permissions
Roles map to permissions that your code and your database policies both check.
Customer portal
Users change plans, update payment methods and download invoices without a support ticket.
Team accounts
Users belong to several teams and switch between them, or work in their personal account.
Billing webhooks
Flat, per-seat and metered subscriptions through Stripe Checkout, with webhooks that keep plans and seats in sync with your database.
Swappable providers
Billing, email, CMS and monitoring sit behind interfaces, so changing provider is configuration, not a rewrite.
Internationalization
Every UI string comes from translation files, so adding a language is content work.
Built for coding agents
Guardrails your agent works inside
Rules, an MCP server and strict checks keep generated code in the kit’s patterns.
Agent rules
AGENTS.md files at the root and in each package teach coding agents the kit’s conventions.
Strict code standards
Strict TypeScript and linting across the monorepo, so type errors surface before your users find them.
MCP server
Gives Claude Code, Cursor, Codex and Gemini structured access to the kit: database, components, translations, checks and PRDs.
E2E tests with Playwright
Tests for authentication, team accounts and invitations, written with page objects you can extend.
You own the code
The full source lives in your repository. Nothing is hidden behind a package you cannot edit.

What customers say
Developers and founders on the kits, the docs and the support. Every quote links to the original post.
just wanna say thanks to @gc_psk for building @makerkit_dev . it is such an overpowered template. like finally we have a really good one with active development, good docs and now even cursorrules/windsurfrules to just sit down and see ai agents do the stuff. truly mindblowing.
Built and maintained full-time by Giancarlo, a software engineer with almost 15 years of experience at startups and enterprises. Support questions reach me directly.
Founder interviews:Rob, Provider.appSebastian, WatchthisMichael, ChatFlow
My favorite so far is @gc_psk and @makerkit_dev ship cursor rules along with updates to the framework. That's been really useful to pull in new version (via git remote) and things stay in sync.
Just started using MakerKit and it's a total game-changer. 🚀 Wish I had this when I was building Phishr. Instant team management and billing? Insane.
Second that! Giancarlo provides amazing support!! 😄
You need to check @makerkit_dev by @gc_psk — it’s the best I’ve seen so far. It’s feature complete, plenty examples, amazing docs, great Discord community, the dude provides support even days after his weeding (which is crazy!) I’m not affiliated in every way, just a happy cx.
Honestly @makerkit_dev is great. More for B2B products but really clean and well documented.
Amazing! @gc_psk has built a masterpiece with this one!
I just stumbled upon @makerkit_dev (and you!), it's impressive, I thought it was a big team behind how many features I saw (and I've been working in software a long time!) I was just looking for a free boilerplate, but the lifetime licence makes it a no brainer. Thank you!
I would have totally agreed with you until… I found @makerkit_dev last year. This is by far, the best boilerplate I found those past years. The dev is pushing new features and updates almost every week. His documentation (specially migrating to Next 15) is the best I’ve seen.
Makerkit is a gem for makers, if I was not building a desktop app I would be using it for sure, maybe for my next project
I landed on MakerKit after getting into boilerplates with ShipFast. Much better.
1000% recommend buying a good boilerplate (or making your own) I use @makerkit_dev it's so good I had an affiliate link, but I can't find it at the moment
For anyone who wants to build their own SaaS, I recommend trying out @makerkit_dev. Thanks to @gc_psk for creating such a fantastic tool that makes building websites a breeze! #SaaS #buildinpublic
We loved the product since when Giancarlo released the first version, and are building upon it ever since for all of our products. Highly recommended for all indie makers out there.
Solid and battle tested boilerplate with an amazing community and support.
In short
The Remix Supabase SaaS boilerplate, one framework version later
Remix ideas, React Router 8 packages, Supabase underneath. Loaders and actions carry over; the package names change.
What is the MakerKit Remix SaaS boilerplate?
The MakerKit Remix SaaS boilerplate is now the MakerKit React Router SaaS Starter Kit: a React Router 8 and Supabase monorepo with authentication, team accounts, roles, invitations, subscription billing, and a super admin. Code written for Remix v2 migrates by changing imports and moving routes into routes.ts.
The Remix model, kept
Loaders, actions, nested layouts, and error boundaries work the way they did in Remix v2.
Typed route modules
Loader and action arguments use generated Route types instead of hand-written generics.
Migration guide
The docs walk through imports, removing json(), typed loaders, and moving routes into routes.ts.
Supabase with RLS
Team data is scoped by Row Level Security policies, the same model the Remix kit used.
Built for AI coding agents
AGENTS.md and CLAUDE.md files at the root and in each package, rules for Claude Code, Cursor, Codex, and Gemini, and an MCP server your agent can call.
Lifetime license, continuous updates
Pay once, then pull new features, fixes, and framework upgrades into your repository with git. Maintained full-time since 2022.
Best for
- Developers who know Remix and want to keep loaders and actions
- Teams with a Remix-era MakerKit app planning the move to React Router
- Products happy to use Supabase for auth, database, and storage
Not for
- Projects that must stay on the Remix v2 packages
- Teams that want Drizzle or Prisma on their own Postgres; the React Router kit is Supabase only
- Anyone who wants React Server Components
With and without MakerKit
Without MakerKit: Porting a Remix SaaS by hand, package by package
With MakerKit: The kit has already moved; a guide covers your own routes
Without MakerKit: Untyped loader arguments inferred from context
With MakerKit: Generated Route.LoaderArgs and Route.ActionArgs
Without MakerKit: A Remix boilerplate frozen at its last release
With MakerKit: A React Router 8 kit that keeps shipping updates

Questions before you buy
Remix SaaS Boilerplate FAQ
Not covered here? Ask in Discord or contact me. Licensing details are in the MakerKit license terms.
Is there still a Remix SaaS boilerplate?
Yes, under a new name. Remix v2 merged into React Router, and the MakerKit Remix Supabase kit became the React Router SaaS Starter Kit, now on React Router 8 and Supabase. Loaders, actions, nested routes, and error boundaries work the way they did in Remix.
What changes for code written for Remix?
Mostly imports and route registration. Imports from @remix-run/react and @remix-run/node collapse into react-router, json() responses become plain returned objects, loader arguments use the generated Route.LoaderArgs type, and routes are declared in a routes.ts file instead of inferred from file names. The kit docs have a step-by-step migration guide.
Does the kit keep the architecture of the Remix version?
Yes. It keeps the Turborepo layout with @kit/ui, @kit/billing, @kit/team-accounts, and @kit/supabase packages, Supabase Auth with Row Level Security for team data, and the billing gateway that switches between Stripe and Lemon Squeezy through configuration.
Should I pick this kit or the Next.js kit?
Pick this one if your team thinks in Remix terms: loaders and actions carry over, and there is no Server Components model to learn. Pick the Next.js Supabase kit if you want React Server Components, or if you may move to Drizzle or Prisma later, since the React Router kit is Supabase only.
Which license includes the React Router kit?
The Supabase stack license. It includes the React Router 8 kit together with the Next.js 16 and TanStack Start Supabase kits, as a one-time purchase with continuous updates.
Is MakerKit a one-time purchase or a subscription?
A one-time purchase. You get a lifetime license to the source code, continuous updates for the stack you bought, and unlimited projects for your own business, with no renewal fee. Building products for clients requires a Team license, and each client that receives the code needs their own license.
What support is included?
Discord support from me, Giancarlo, the founder who works on MakerKit full-time, and from the community. I help with setup, kit-related issues, and questions about the codebase. Team licenses add a private Discord channel for your team.
Still thinking in loaders and actions? This is your kit.
Keep the Remix model, move to React Router 8, and skip rebuilding auth, teams, and billing. The migration guide covers your own routes, and updates keep coming after you buy.
