Overview

RedwoodJS, the full-stack React and GraphQL framework, changed direction in April 2025. The team split its work into Redwood GraphQL, the existing framework, which continues to get maintenance releases without new features planned, and RedwoodSDK, a new framework where development now happens. The Redwood blog says RedwoodJS apps remain supported but recommends RedwoodSDK for new projects.

RedwoodSDK is a server-first React framework for Cloudflare. It begins as a Vite plugin enabling server-side rendering, React Server Components, server functions and streaming, and adds a type-safe, web-standards router with middleware. It avoids code generation and implied routing: routes are plain TypeScript functions. A useSyncedState hook synchronises state across connected clients in real time without writing WebSocket handlers.

The trade-off is lock-in by design: the repository says it runs on Cloudflare (workerd) only, and local development uses Miniflare to emulate Workers, D1, R2, Queues and Durable Objects. RedwoodSDK 1.0 entered beta in October 2025. Like other RSC frameworks, its package (rwsdk) was listed as affected by the December 2025 React Server Components vulnerability.

Pricing and plans

RedwoodSDK is free and open source. Apps run on Cloudflare Workers, so runtime costs follow Cloudflare's own pricing for Workers, D1, R2, Queues and Durable Objects.

Source: docs.rwsdk.com/ · prices as published, excluding tax.

§3

What it does

Vite plugin
Starts as a Vite plugin; no custom build tool.
Server Components and server functions
Async server components, server actions and streaming responses.
Standards-based router
Type-safe routes as functions, with middleware and interrupters for request control.
Realtime state
useSyncedState synchronises state across all connected clients.
Cloudflare bindings locally
Miniflare gives D1, R2, Queues and Durable Objects in local development.

Strengths and limitations

Strengths

  • Direct access to Cloudflare's database, storage and realtime primitives.
  • No code generation or hidden routing conventions.
  • Local development mirrors production through Miniflare.

Limitations

  • Runs on Cloudflare Workers only; you cannot deploy it to a generic Node host.
  • Young framework: 1.0 entered beta in October 2025.
  • Not a drop-in upgrade for RedwoodJS apps; the old framework continues as Redwood GraphQL.
  • Server Components expose it to RSC security issues such as CVE-2025-55182 (December 2025).
§5

Who it suits

Good for

  • Full-stack React apps committed to Cloudflare
  • Realtime collaborative apps using Durable Objects
  • Small teams that want few abstractions

Look elsewhere if

  • Apps that must run on AWS, a VPS or any Node host
  • Existing RedwoodJS GraphQL apps expecting an in-place upgrade
§6

Pricing history

  • RedwoodJS splits into Redwood GraphQL and RedwoodSDK

    Announced 4 April 2025: the original RedwoodJS framework continues as Redwood GraphQL with maintenance but no new features planned, while new development moves to RedwoodSDK, a React framework that runs only on Cloudflare. Source ↗

Questions

What happened to RedwoodJS?

In April 2025 it became Redwood GraphQL, which stays maintained without new features planned, while new framework work moved to RedwoodSDK.

Can RedwoodSDK run outside Cloudflare?

No. Its repository states it is for Cloudflare's workerd runtime only.

Does RedwoodSDK use React Server Components?

Yes. It enables RSC, server functions and streaming through its Vite plugin.
