Stop vibe-coding from scratch. Start with a SaaS codebase AI can actually extend.
Give your AI a Next.js SaaS boilerplate it can extend - with auth, payments, database adapters, admin dashboard, SEO-ready blog, and conventions already wired.

AI can write code. It still needs architecture.
Starting from a blank repo with AI feels fast at first. Then the duplicated logic, inconsistent patterns, unclear data flow, and half-wired integrations start piling up. Frontend Accelerator gives your AI tools a clean SaaS foundation to build on - with the boring but critical pieces already connected.
AI speed is useful. AI speed on top of working conventions is what stays maintainable.
The honest comparison
Why not just vibe-code it from scratch?
Because AI is fastest when it has strong patterns to follow. A blank repo gives it too many decisions to guess. Frontend Accelerator gives it a working SaaS structure, so new features are built on top of real conventions instead of one-off generated code.
Blank repo + AI
Fast start, too many architectural decisions for the model to guess, messy later.
Free starters
Useful for scaffolding, but usually too basic once auth, billing, data, and roles meet.
Expensive boilerplates
Powerful, but often broader and more complex than a solo builder or freelancer needs.
Frontend Accelerator
Opinionated, AI-ready, practical, and built around the SaaS layers you actually need.
The critical SaaS setup, already connected
A SaaS foundation built for AI-driven development. Not just faster, but smarter.

Baked-in guardrails
The rules your AI follows. Pre-written. Ready on clone.
These files document the architectural decisions your AI tools need before they start adding features.
Gives Cursor and Windsurf explicit guidance about where code belongs, which patterns to follow, and which areas need care.
# Frontend Accelerator — Cursor Rules ## Architecture zones - Features: src/features/<name>/ — isolated, no cross-imports - Shared: src/shared/ — only if used by 2+ features - Protected: src/lib/, src/config/ — never modify without instruction ## NEVER do - Import Stripe or Firebase directly in features - Add business logic to app/ directory - Use `any` type
Provides Claude with project-specific architectural context, conventions, and adapter boundaries.
# Frontend Accelerator ## Before touching any file 1. Check: does a pattern exist in src/features/? 2. Check: is this file in the Protected Core? 3. Check: will this introduce a cross-feature import? ## Adapter pattern (MANDATORY) All DB access via DatabaseAdapter All payments via PaymentAdapter Direct SDK imports in features: PROHIBITED
Provides GitHub Copilot with the same project conventions used across the rest of the codebase.
## Zone system Protected Core: src/lib/, src/config/, src/types/ Semi-Protected: src/shared/ (modify with caution) Open: src/features/, app/ ## Result pattern Use ok/err/tryCatch — never throw for control flow ## Import rules Use @/ absolute imports only No barrel imports (index.ts)
All three instruction files ship in the repo and can be adapted to your project.

Reviews
Trusted by developers like you
Frontend Accelerator is incredibly fast, intuitive, and easy to use. It has saved me so much time with its clean interface and efficient workflow. The features are powerful yet simple, making it perfect for any developer. Highly recommended for anyone wanting to speed up their projects!
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. I definitely recommend checking this solution out if you want to speed up your frontend workflow.
A great Swiss knife rich in options to start with a Next.js project.
Frontend Accelerator made my entire development so much easier as it handles all the setup and boilerplate, which allow me to focus on just building my MVP instead of dealing with setup headaches. My favorite part is the pre-built UI components, especially the hero section with different variations to choose from. The authentication and payment setup has also been a huge time-saver—it just works right after small configurations. Im also using Stripe for payments, and I love that there are predefined callbacks that make handling subscription events really easy. On top of that, the folder structure is also easy to understand, which made it super quick to get onboarded. I really havent tried the locales yet and looking forward to it once i enabled my mvp to other markets.On top of that, the folder structure is also easy to understand, which made it super quick to get onboarded. I really havent tried the locales yet and looking forward to it once i enabled my mvp to other markets. Even though I'm still in development, it's already helped me move way faster than I expected and currently just focus on the business logic of my MVP.
As a designer possessing beginner-level fullstack skills, the Frontend Accelerator has taken much of the upfront labor in both tech stack research and coding knowledge needed to scaffold and deploy a SaaS product securely, saving me hours of time so that I can get right to the important and rewarding work, designing SaaS apps. Highly recommended to beginner and experienced SaaS app soloperneuers. Worth every penny!
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. Thanks so much Tomas!
Frontend Accelerator helped me to develop faster my startup project.

About Me
Built from real SaaS work, not tutorial boilerplate.
I built Frontend Accelerator after repeatedly wiring the same critical SaaS layers: authentication, payments, database access, dashboards, roles, content, and deployment-ready structure.
The codebase uses boring, proven integrations and explicit conventions. It is designed for AI-assisted development, but it stays readable by humans when you need to understand, debug, or extend it yourself.
Frontend Accelerator is the foundation I wanted before opening an AI coding tool: enough structure to guide every new feature without turning the project into an over-engineered framework.
