We just want you to know, that we shipped the first WebAssembly runtime in Rust before either was cool. Thank you for your attention on this matter.

An AI agent just wrote and launched a Node.js website… fully inside a browser tab 🤯 Introducing Pi on Wasmer: → Unmodified. Zero patches → Fully sandboxed with WebAssembly → Works in the browser and on iPhone Try it yourself 👇 wasmer.sh

That's an accurate take. Now is time to define what's going to be the right primitive 😉

A lot of the long-running persistent sandbox stuff today feels like lift-and-shift. I suspect sandboxes will evolve from being “devboxes in the cloud” to something much more ephemeral. One environment for every _command_. And snapshotting in between so you can pause/resume/clone.

AI can write software. What happens when it can deploy and run it too? We’ve been building the infrastructure for that future. Unveiling Oct 5 at #SFTechWeek. partiful.com/e/e7nzsUEwK4p3c…

This is a great example of using the right tech for the problem, and how important is to be always pragmatic with the solution. In this case, moving from Wasm to JS improved the performance of Three.js' tangent gen by ~4x and the size by 75%. Keep up the good work @mrdoob!

This environment exists today: is called Wasmer. Wasmer can run bash, Node.js fully (including Next.js, Astro), Python fully (including FastAPI, FastMCP and Flask) and even PHP 🤯 In the browser, embedded, or in the server

MCP vs CLI for LLMs is the wrong discussion. People are debating at the wrong layer. Both work incredibly well as long as they are run through a repl like environment that can persist state. The funny thing about CLI is that CLI tools are usually accessed through BASH which happens to be a repl with persistent state (the file system), therefore cli works much better than mcp. But this isn't even close to being an intrinsic property of MCP. Just means that we need better harnesses. Right now the best repl for this are: - bash + fs - jupyter kernels - codemode type repls, usually quickjs LLMs understand the concept of forward evolving a system to solve a need very well. This comes from the agentic RL. They understand how to change the state of a codebase or acquire data from databases and then operate on it similarly to humans. But without an execution environment, they actually cannot do this properly. My bet? Sometime soon someone will (or has already?) create a embeddable, sqlite style mini execution environment that parses bash, typescript, or tool calls into a common IL execution plan that's easy to security check before executing. And design this specifically for durable execution environments. Then we will just connect cli, mcp, webmcp, whatever to that and it accepts any of the input modalities as they can all be represented as each other.
