Code execution is the ultimate tool call. Here we're using ForeverVM with boto3 to visualize our AWS infrastructure without needing specialized tools.

Had a blast hosting MCP Lightning talks SF with Cloudflare! Thanks to everyone who spoke. Doing it again next week in NYC.

Code execution is the ultimate tool call. Once an LLM can run its own code, it can run loops, access APIs, and extract the result. In this video, Windsurf uses ForeverVM to make HTTP calls to check a list of Python packages against the latest PyPi version.

Because ForeverVM keeps REPLs alive forever, you can ask Claude unlimited queries about a dataset and Claude can always access the same context.

Give Claude the power of a Python REPL. Perform complex data analysis or draw a mandlebrot with ASCII characters. Install ForeverVM as a tool on Claude Desktop: https://forevervm-com.vercel.app/docs/guides/forevervm-mcp-server/

Signups for ForeverVM are now open! If you have node.js or uv, you can sign up from your terminal with a one-liner. npx forevervm signup Or read our new docs for more: https://forevervm.com/docs

Jamsocket is now officially SOC 2 Type II compliant! Whether you use our managed platform or bring-your-own-cloud, rest easy knowing that we put security and reliability first.

Giving an LLM a code sandbox massively increases its capabilities, but managing VM lifecycles is a pain. Introducing foreverVM, a Python REPL-as-a-service. Under the hood, we swap between memory and durable storage. To you (and your agent) it acts like an always-on REPL. See more at forevervm.com

Y-Sweet now supports Read-Only Tokens for use cases where a client should only have read access to a document. See docs at https://docs.jamsocket.com/y-sweet/features/read-only-tokens

New demo drop! https://demos.y-sweet.dev/monaco Collaborate in code with Monaco and Y-Sweet

In Learn Yjs lesson 3, we look at another classic app: the todo list! This demo allows each client to reorder the todos and toggle their checkboxes.

In Learn Yjs lesson 2, we look at the “hello world” of JavaScript framework demos: the humble click counter. Seems pretty simple, right?

Yjs is a CRDT that stores its state in documents and syncs them between clients. Here you can see how Yjs syncs documents between clients. When one client moves a slider, the other client automatically sees the updated value.

Want to learn about building local-first apps? Check out Learn Yjs, our interactive guide to Yjs! Featuring three lessons jam-packed with explorable explanations and coding exercises.

Something cool coming tomorrow 👀

Read our interview with @bastiendolla.bsky.social, cofounder of Rayon. We talk about why Rayon replaced their database with Jamsocket, building Rayon V2 and features like version control. jamsocket.com/blog/why-ray...

the most important part of this announcement is that this will save me, personally, $55/mo by switching waypoint.jakelazaroff.com away from cloudflare

Curious about building real-time collaborative apps? 🛠️ @felchang.bsky.social from @jamsocket.com joins @seancdavis.com to showcase how to create seamless collaboration using Y-Sweet, @supabase.com, and Netlify Extensions. Watch now: youtu.be/lc401-KkwkQ?...

"Users have come to expect multiplayer for any design tool on the web right now." Read about why @flairAI_ chose Y-Sweet to do the job. https://buff.ly/3BCpJuo

Y-Sweet + BlockNote gets you pretty darn close to a Notion-like experience. Get a working version with our tutorial: https://docs.jamsocket.com/y-sweet/tutorials/blocknote

5 launches in 5 days. Find our launch week recap at https://jamsocket.com/launch-week/0

To finish off Launch Week, we're launching the best Y-Sweet feature yet: 10GB of Free Storage on Y-Sweet’s completely free tier, so you can hack through the holidays 🎄 ❄️

Collaborative rich text editing is one of the most popular use cases for Yjs. Today, we're releasing our BlockNote Y-Sweet demo, which get's the job done in just a few short lines of code! https://buff.ly/4g41ggn

Launch Week Day 3! We wanted to show how to use Y-Sweet in combination with a relational DB, so we built a demo pairing Y-Sweet's document collaboration with Supabase for user and permission management. Try a demo: https://buff.ly/4gg7utf

For launch week day two, we're launching the create-y-sweet-app command line tool. Use it to bootstrap a Next.js or Remix app with Y-Sweet ready to go.

We built Y-Sweet to be the zero-lock-in sync engine, so it uses your storage as the source-of-truth. We know some users just want an all-in-one solution, so our first Launch Week launch is managed storage for Y-Sweet! See the docs: https://buff.ly/4eURonN

Thanks @yonz.bsky.social for having us at the Local First Meetup today! Such great company being onstage with @zxch3n.com and x/@SahilLalani0 Check x/@felchang's talk on Y-Sweet and the rest of the recording at

We're doing Launch Week with @supabase from December 2-6, and it's going to be sweet! https://buff.ly/4fWm9d1
