- The type of state that is synced between the server- and client-side (read-only on client-side)

- Server procedures that clients can call to make mutations on server-side

- Client procedures that servers can call to make queries etc. to the client-side

All connections share the same state, and the state is always defined by the server. Deltas are efficiently synced through JSON-style patches (using immer under the hood).

We’re Glenn and Julian, and we built this as a tool for our startup (stagewise - YC S25). We needed a simple and type safe solution to sync a CLI app (JS-app) with a browser-based UI-app (we use React). We didn’t find any solutions out there that seemed easy to use, so we simply decided to build our own one.

We offer both the server and client in vanilla TS, but also ship a React-specific client that gives you a Zustand-style access to the state (allowing to only select slices of the whole state as well).

The API is made to be very easy to use, with just one output type that’s shared between server and client apps, making it a low-overhead solution if you build locally running JS apps that consist of multiple sub-apps. Karton is MIT-licensed, available on npm (@stagewise/karton) and currently part of our bigger OSS monorepo. It’s pretty much in beta state but we already use it in production.

We’re compatible with any framework and any component library. Think of it like a v0 of Lovable that works locally and with any existing codebase.

You can spawn the agent into locally running web apps in dev mode with `npx stagewise` from the project root. The agent lets you then click on HTML Elements in your app, enter prompts like 'increase the height here' and will implement the changes in your source code.

Before stagewise, we were building a vertical SaaS for logistics from scratch and loved using prototyping tools like v0 or lovable to get to the first version. But when switching from v0/ lovable to Cursor for local development, we felt like the frontend magic was gone. So, we decided to build stagewise to bring that same magic to local development.

The first version of stagewise just forwarded a prompt with browser context to existing IDEs and agents (Cursor, Cline, ..) and went viral on X after we open sourced it. However, the APIs of existing coding agents were very limiting, so we figured that building our own agent would unlock the full potential of stagewise.

Since our last Show HN (https://news.ycombinator.com/item?id=44798553), we launched a few very important features and changes: You now have a proprietary chat history with the agent, an undo button to revert changes, and we increased the amount of free credits AND reduced the pricing by 50%. We made a video about all these changes, showing you how stagewise works: https://x.com/goetzejulian/status/1959835222712955140/video/....

So far, we've seen great adoption from non-technical users who wanted to continue building their lovable prototype locally. We personally use the agent almost daily to make changes to our landing page and to build the UI of new features on our console (https://console.stagewise.io).

If you have an app running in dev mode, simply `cd` into the app directory and run `npx stagewise` - the agent should appear, ready to play with.

We're very excited to hear your feedback!

Sounds cheesy, but the focus on really really nailing this one thing sets us apart we think.
