stagewise

olutions 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.

d 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. Here's how it works: When you run `npx stagewise`, our cli proxies your running web application in dev mode and injects a toolbar containing the coding agent on top of it. Each prompt you send will be enriched with browser context and sent to our cli, which will call our backend and modify the source code of your local codebase accordingly. Here's a demo of our agent changing the login UI of Cal.com, a popular open-source meeting scheduling app: https://www.youtube.com/watch?v=BkDcAozK9L4. 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!
