See how Wasmer used Codex with GPT-5.5 to build a Node.js runtime for the edge, accelerating development 10x to 20x and shipping in weeks instead of months.
Teams use Codex with GPT‑5.5 to take on more ambitious projects and complete them 10x to 20x faster.
Engineers at Wasmer experienced a breakthrough this year: They figured out how to run Node.js workloads inside a WebAssembly sandbox, enabling developers to run JavaScript apps, MCPs, and agents without Docker. This effort would have taken one year without Codex, but with Codex, it took two weeks. Now, they’re the first cloud host to provide full Node.js at the edge layer.
Wasmer is a young company with a small team and a big goal: an edge computing platform that scales across local and global environments without platform restrictions.
“The kinds of projects that we are taking on are incredibly ambitious, and it would have taken us ages to do them without AI,” says Syrus Akbary Nieto, Founder and CEO. “Now, things are way simpler and faster.”
That simplicity and speed translated directly into a groundbreaking project: Edge.js(opens in a new window), a JavaScript runtime that can run Node.js workloads for AI and edge computing.
It’s a project the team had long wanted to take on, but they didn’t always have the resources to do it. “Everyone here is very, very technical, but we just didn't have the time to dedicate to these projects. And now, we can launch new products that would have been impossible before,” explains Nieto.
