✕ The Chaos
- AI scatters business logic across UI files
- Cursor hallucinates imports that don't exist
- AI rewrites your entire DB layer from scratch
- You spend Friday reverting AI changes
- Three different auth implementations in one app
- AI writes code that doesn't fit your architecture
- Inconsistent patterns across features, projects, and teams
✓ With Frontend Accelerator
- Feature-folder structure your AI always follows
- Strict TypeScript catches wrong shapes instantly
- One database adapter — one pattern, forever consistent
- Pre-written rules keep your AI in its lane from prompt one
- NextAuth fully wired — AI extends it, never rewrites it

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
Hey there, fellow developer 👋
As a developer myself, passionate about building impactful web products, I've launched several side projects over the years - from AI-powered tools and online courses to Chrome extensions.
Along the way, I found myself constantly repeating the same boilerplate setup: auth, payments, database, dashboard, deciding file structure, etc. You know the pain. So instead of rebuilding the wheel each time, I've taken everything I've learned - proven patterns, battle-tested practices, and real-world lessons - and poured it into a single, reusable foundation.
Frontend Accelerator is that foundation - built not just to save time, but to help developers launch with confidence, speed, and clarity.
