TLDR

A fullstack toolkit that adds the missing backend and data layer to Next.js, so you can build complete web apps, user-facing pages and server-side logic, in one project without stitching together separate tools.

In plain English

Blitz is a toolkit for building web applications, described by its makers as the missing fullstack toolkit for Next.js. Next.js is a popular framework for building websites and web apps with JavaScript. The word fullstack means it covers both the part of an app that users see in their browser and the behind-the-scenes part that stores and processes data, so Blitz aims to fill in pieces that Next.js does not provide on its own. The README is mostly a welcome page rather than a deep technical guide, so the clearest concrete information it gives is how to get started. You install Blitz as a command-line tool using a package manager such as npm or yarn. Once it is installed, you create a new project by running a single command, move into the new project folder, and start a development server. Within a minute or two you can open a browser and see a working starter app running on your own computer. A large part of the README is given over to the community and the people behind the project. It points to a Discord chat where users help each other build apps and where the maintainers collaborate on Blitz itself, plus a forum for longer questions and a contributing guide for people who want to help with the code. The project explicitly states that its community is welcoming and inclusive, and it lists the core team and maintainers by name. The page also covers how the project is funded. Blitz relies on financial sponsorship, with monthly options starting at five dollars, and it thanks its sponsors across several tiers. This is a common arrangement for open-source projects that are maintained by volunteers rather than a single company. Because this is the overview page, it does not go into the details of how to actually build features. The full README is longer than what was shown.

Copy-paste prompts

Prompt 1
Using Blitz.js, scaffold a new fullstack Next.js app with user authentication and a simple database-backed to-do list, then walk me through the generated folder structure.
Prompt 2
How do I add a new database model and a server-side query to an existing Blitz.js project?
Prompt 3
What does Blitz.js add on top of plain Next.js, and when should I use Blitz instead of just Next.js alone?
Prompt 4
How do I run the Blitz development server and open the starter app in my browser for the first time?
