AI-ready Next.js SaaS foundation

Vibe code the product. Not the infrastructure.

Start with a SaaS foundation that gives your AI agent clear rules, a place for every feature, and working patterns to follow - so the code stays understandable as your product grows.

Building with AI. Staying in control.

Use it with your favourite AI agent:

Why the foundation matters

Building fast with AI needs clear boundaries.

From a blank repository, every prompt can choose a different place for features, a different way to connect payments and data, and a different pattern to repeat. Frontend Accelerator gives your agent the rules and working examples first.

Starting from scratch

  • Let each prompt decide where code belongs
  • Introduce different patterns for similar features
  • Spend more time reviewing foundation decisions

Starting with Frontend Accelerator

  • Begin with a working structure
  • Give every agent the same project rules
  • Move into the parts that make the product different

The goal is not less AI. It is better context for AI.

A reusable way to build

One foundation. Many SaaS products.

Use the same structured starting point across client MVPs and SaaS products. Your agent follows the same rules while you focus on what makes each product different.

Build what makes the product different

Start past the recurring setup. Put your attention into the workflows, experience, and details that make each product worth building.

Your agent knows where new code belongs

Give Cursor, Claude Code, Copilot, Windsurf, and other agents the same rules, examples, and place for every feature.

Keep the code easy to review and hand over

Keep the complete TypeScript source inside a structure you can review, explain, and pass to the next developer.

How the foundation works

Your agent knows where new code belongs.

Every coding agent starts with the same project rules and working examples. Features have a clear home, reusable Skills guide common work, and provider code stays separate from the product built on top.

AGENTS.md

One set of project rules

Cursor, Claude Code, Copilot, and Windsurf start from the same instructions and checks.

.agents/skills/

Reusable Skills

Agents can load repo-local guidance for Next.js, Stripe, testing, accessibility, and other recurring work.

src/features/<feature>/

A clear home for each feature

New product behavior has a known place instead of spreading through whichever file was convenient.

src/lib/**/adapters/

Payments, data, and AI stay separate

Provider code stays away from the product features that use it, so changes are easier to trace.

The recurring work

... and the common SaaS systems are already connected.

These are not the whole product. They are a working example of how the structure fits together—and a head start you do not have to rebuild for each new project.

Authentication

Google, GitHub, Facebook, and email magic links

Payments

Stripe or Lemon Squeezy, including payment webhooks

Database

Choose Firestore or MongoDB while provider code stays separate

Roles and access

Admin and member access with protected admin routes

Dashboard

Working profile, product, user, and content areas

Content and SEO

Blog, glossary, metadata, related content, and sitemaps

Localization

Ready for multiple languages

Email

SMTP support for sign-in and application email

UI foundations

Responsive marketing, sign-in, and dashboard components

From purchase to product work

Clone it. Configure it. Build what makes the product different.

Frontend Accelerator gives you the starting point. You stay responsible for the product and what ships.

Step 1

Start with the codebase

Clone the complete TypeScript source and begin from a working project instead of another blank repository.

Step 2

Choose the providers you need

Configure Firestore or MongoDB, Stripe or Lemon Squeezy, sign-in methods, email, and your product plans.

Step 3

Tell your agent what makes the product different

Give it the project rules, then use it for the routes, workflows, and product behavior your users actually need.

Step 4

Ship your SaaS. Start selling.

Review what ships, test the customer and payment flows, then launch, start charging, and improve the product from real feedback.

What customers noticed

Less setup. Clearer code. Help when you need it.

“This is a fantastic and well-built Next.js boilerplate that makes launching new projects fast and hassle-free. Huge shoutout to Tomas for not only building such a well-structured and efficient setup but also for his support and taking the time to answer my technical questions.”

“The authentication and payment setup has also been a huge time-saver—it just works right after small configurations. On top of that, the folder structure is also easy to understand, which made it super quick to get onboarded.”

“Was having some hiccups around integration setup (payments and login). Tomas was willing to hop on a zoom call and work through the issues 1:1! It's a great start for individuals or companies looking to get started with a SaaS.”

Tomas Mikula

Creator of Frontend Accelerator

I built Frontend Accelerator because every new SaaS project kept repeating the same infrastructure and architecture decisions. The idea is simple: start from a foundation that already works together, give AI clear boundaries, and spend your time building the actual product. You ship faster, make fewer structural mistakes, and end up with a codebase that’s still easy to review, maintain, and hand over.

Is it for you?

For developers building SaaS to ship, grow, and sell

Use AI to build the product on top of a structured foundation with clear boundaries, reusable infrastructure, and rules your agents can follow.

A strong fit when

  • Freelancers and solo studios delivering SaaS products or client MVPs
  • React developers who want a repeatable starting point for new products
  • Teams using Cursor, Claude Code, Copilot, Windsurf, or similar agents
  • Technical founders who know React and basic Next.js
  • People who plan to review, maintain, and hand over the source code

Choose another starting point when

  • People looking for a no-code tool
  • People looking for a course that teaches React or Next.js from zero
  • Teams that need organization multi-tenancy, enterprise SSO, or compliance systems out of the box
  • Projects that require PostgreSQL or Supabase without adding a new database adapter

Choose how you want to start

Start with the foundation. Add guidance if you need it.

Start with the private source and use it as the working structure for your SaaS. Choose Guided Launch when you want direct help setting it up for your project.
