return new Response(`This is room ${party.id}`);
}
}
// 3. Develop on localhost
npx partykit dev server.js
// 4. Deploy to the edge

// 5. Try it out
curl 'https://first-party.{yourname}.partykit.dev/party/my-room'
Add PartyKit to everything
It works well with with popular collaboration frameworks and libraries. Y.js, Automerge, Replicache, XState, tldraw, TinyBase, they all Just Work™.

More functional
Analytics, staging environments, secrets management, logging. All the tools your team needs to build production apps.
More fast
A worldwide edge network with low latency, anywhere on Earth. We enable your ambition, from your first user to millions.
I did a bunch of work recently with Y.js and PartyKit and can confirm it made some of the most difficult parts a breeze. You should 100% try it out at least if it’s relevant to what you’re building.
It’s the future of workflows.
I have been trying to solve a real-time sync problem for SiteGPT for months now. I tried everything and nothing seemed to work properly. Sunil solved my entire problem using PartyKit in around 10 lines of code 🤯 10 lines... and I am not even exaggerating 😅 PartyKit is awesome!!
Oh god this is so easy
A breeze to set up 🙂 Just takes less than 40 lines of code to do! Looking forward to the future of PartyKit!
We’ve been having a blast using PartyKit at StatelyAI for a little while. It makes implementing real-time a breeze. Try it on your next thing 🎉
