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/

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.

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.
