What Blitz.JS does
Blitz.JS is an open-source fullstack toolkit for React-based web applications, founded in February 2020 by Brandon Bayer. It positions itself as the missing fullstack layer on top of Next.js, providing battle-tested libraries and conventions for shipping production web applications. The project's core technology stack is built on Next.js with TypeScript, Prisma ORM (default), React Query via the Blitz RPC layer, Zod for validation, SuperJSON for serialization, Vitest for testing, and React Final Form for forms. Its differentiating technical feature is the Blitz RPC typesafe API layer, which allows developers to import server code directly into the frontend and have the build system automatically insert remote procedure calls, eliminating the need for a traditional REST or GraphQL API layer. Other core products include Blitz Auth (built-in authentication with support for Auth0, GitHub, Google, and self-hosted email/password), Blitz CLI (scaffolding and code generation), Blitz Recipes (one-command installation of libraries like Tailwind, Chakra UI, and Material UI), Route Manifest (type-safe routing), and framework adapters (@blitzjs/next, @blitzjs/auth, @blitzjs/rpc).
Blitz.JS serves JavaScript and React developers building fullstack web applications, with primary use cases spanning small projects to production-scale database-backed monolithic applications and migration of existing Next.js apps. Secondary segments include beginner developers seeking convention-over-configuration guidance and enterprise teams looking for monolithic architecture simplicity. Distribution is exclusively through the npm registry and GitHub, with a community-led go-to-market model leveraging Discord, GitHub Discussions, Twitter, and documentation.
The project is a community-driven open source initiative with no commercial revenue model. The framework is free with no paid tiers, no subscriptions, and no enterprise pricing. Financial support comes entirely through voluntary GitHub Sponsorships starting at $5/month. There is no disclosed institutional ownership, no venture capital backing, no parent company, and no formal corporate structure. The legal entity is listed as 'Blitz.js Contributors.' The core team consists of three members: Brandon Bayer (Creator), Dillon Raphael, and Siddharth Suresh, supported by a layered maintainer community (L1 and L2 maintainers) and over 350 total GitHub contributors.

Blitz.JS product offering
Product offeringCore offering
Blitz.JS is a free, open-source fullstack toolkit for Next.js (and other React frameworks) that provides a typesafe RPC layer, built-in authentication, and CLI-based code scaffolding. The framework eliminates the need for traditional REST or GraphQL APIs by enabling direct server-to-client function imports with full end-to-end TypeScript typesafety, and bundles opinionated defaults for auth, forms, validation, and testing to let developers set up new apps in minutes rather than weeks.
Product overview
Blitz.js is a fullstack, framework-agnostic toolkit designed to work with Next.js, Remix, SvelteKit, and Nuxt. The core offering consists of Blitz.js itself, the Blitz RPC (Zero API Layer) for typesafe data fetching, Blitz Auth for authentication and authorization, and Blitz CLI for project scaffolding. The toolkit provides opinionated defaults while remaining pluggable: Blitz Recipes enable one-command installation of styling libraries (Tailwind, Chakra UI, Material UI) and other packages; Blitz Code Scaffolding generates CRUD boilerplate; the Route Manifest provides type-safe routing; and Blitz Middleware enables HTTP-level customization. Supporting infrastructure includes Blitz Logger (tslog-based), Blitz Validator (Zod integration), and Blitz Testing Utilities (Vitest, Cypress, Testing Library). The @blitzjs/next, @blitzjs/auth, and @blitzjs/rpc packages are modular adapters that can be integrated into existing Next.js applications or used in new Blitz projects. The toolkit is database-agnostic with built-in support for Prisma (SQLite, PostgreSQL) and extensible to Redis, Fauna, and DynamoDB.

Products and services
- Blitz.JS (Core Framework) The Missing Fullstack Toolkit for Next.js providing battle-tested libraries and conventions for shipping and scaling world-wide applications. Built as a framework-agnostic toolkit compatible with Next.js, Remix, SvelteKit, and Nuxt, it targets JavaScript and React developers building fullstack web applications.
- Blitz RPC Typesafe Remote Procedure Call API layer that enables importing server code directly into the client with full typesafety. Eliminates the need for traditional REST or GraphQL APIs by automatically inserting RPC API calls at build time.
- Blitz Auth Built-in authentication and authorization system for Next.js with session management, cookie-based storage, and support for any identity provider including self-hosted email/password, Auth0, GitHub OAuth, Google OAuth, Passport.js, and NextAuth.
- Blitz CLI Command-line interface providing commands for project scaffolding (blitz new), development (blitz dev), building (blitz build), code generation (blitz generate), database management (blitz prisma), and more.
- Blitz Recipes One-command code and package installation system (e.g., 'blitz install tailwind' or 'blitz install chakra-ui'). Recipes can modify almost anything in a project including adding dependencies, changing code, and adding code. Written via MDX and composable like React components.
- Blitz Toolkit (pivoted framework-agnostic version) Framework-agnostic fullstack toolkit that preserves Blitz's world-class developer experience and features while bringing them to all Next.js users and optionally Remix, SvelteKit, Nuxt, and other frameworks.

Blitz.JS competitors and assessment
Company assessmentDirect peers
- tRPC: tRPC provides end-to-end typesafe APIs without schemas or codegen, directly overlapping with Blitz RPC's value proposition. Both are TypeScript-first solutions for eliminating REST/GraphQL boilerplate between frontend and backend.
- RedwoodJS: RedwoodJS is an opinionated fullstack React framework inspired by Rails that similarly bundles conventions, scaffolding, authentication, and a typesafe data layer (GraphQL-based). It targets the same developer persona seeking batteries-included React tooling.
- Remix: Remix is a fullstack React framework with nested routing, loaders, and actions for data fetching. It directly competes with Blitz for fullstack React developers and is explicitly listed as a target framework for Blitz's framework-agnostic pivot.
Broad incumbents
- Nuxt:
- Next.js: Next.js is the React framework Blitz builds on and extends. They serve the same fullstack React developer audience with overlapping capabilities (data fetching, routing, SSR), but Next.js is a much broader, Vercel-backed framework where Blitz positions itself as a specialized toolkit layer.
- SvelteKit: SvelteKit is the fullstack framework for Svelte, analogous to Next.js for React. It is explicitly listed as a target framework in Blitz's framework-agnostic pivot, making it a comparable fullstack JS framework with similar conventions and routing model.

When was Blitz.JS founded?
Blitz.JS was founded in 2020.
How does Blitz.JS make money?
One revenue line is on record: open Source Framework.
Who are Blitz.JS's main competitors?
Direct peers on record are tRPC, RedwoodJS and Remix. Broad incumbents are Nuxt, Next.js and SvelteKit.
Does Blitz.JS have an API?
Yes. Blitz RPC (Remote Procedure Call) provides a typesafe API layer that eliminates the need for traditional REST or GraphQL APIs. With Blitz, developers can import server code directly into the frontend and Blitz automatically inserts an RPC API call at build time that runs the server code on the server. This 'Zero API Layer' approach abstracts the API into a compile step. The API supports query resolvers, mutation resolvers, useQuery, usePaginatedQuery, useInfiniteQuery, and useMutation hooks for client-side data fetching. Authentication is handled via Blitz Auth with session-based tokens and anti-CSRF protection.
What industry is Blitz.JS in?
Blitz.JS's product category is Web Application Framework. Its primary akta.pro industry code is HDAEAKAA, Low-Code/No-Code Application Platforms, with a secondary code of BPAMAOAE, Webhooks, Eventing & Message Streaming. Its NAICS code is 541512 and its SIC code is 7372.
