Blitz

Fullstack toolkit built on top of Next.js that bridges the gap between frontend and backend development.

Overview

Blitz.js is a fullstack toolkit built on top of Next.js that bridges the gap between frontend and backend development. It provides battle-tested libraries and conventions for shipping and scaling applications, allowing developers to build and iterate on features significantly faster than with traditional REST or GraphQL approaches.

The framework emphasizes developer experience through typesafe RPC-based APIs, built-in authentication and authorization, code generation, and scaffolding tools. Blitz supports both monolithic architectures and microservices, with flexible conventions that can be customized when needed. It's designed to be easy for beginners to start with while remaining scalable for growing teams and codebases.

Key features

Typesafe RPC API layer
Built-in authentication and authorization
Code generation and scaffolding
Convention over configuration
Database agnostic (Prisma default)
One-command recipe installation
First-class TypeScript support
Backend architecture support for emails, cron jobs, and background processing

Pros

10x faster feature development compared to REST/GraphQL
Full end-to-end type safety without separate type generation
Minimal setup time (2 minutes vs 2 weeks)
Flexible and pluggable architecture
Easy to migrate existing Next.js apps
Comprehensive authentication with third-party integrations
Active community with Discord and forum support

Cons

Requires Next.js as a foundation
Minimal backend documentation (acknowledged by team)
Opinionated structure may not suit all use cases
Learning curve for developers unfamiliar with Next.js

Use this if

You want to build fullstack Next.js applications with minimal boilerplate, need typesafe APIs, require built-in authentication, or are prototyping rapidly with a focus on developer experience.

Skip this if

You need a framework independent of Next.js, prefer REST or GraphQL APIs, or require extensive backend documentation and patterns out of the box.
