Teams use Codex with GPT‑5.5 to take on more ambitious projects and complete them 10x to 20x faster.
Key facts
- Teams use Codex with GPT‑5.5 to take on more ambitious projects and complete them 10x to 20x faster
- But Codex, Nieto says, “could master console logs to trace calls and a low-level debugger like LLD, which accesses things on the assembly level
- 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
- As Codex’s reasoning abilities evolve, Wasmer engineers spend less and less time with handholding
Summary
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. 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. That simplicity and speed translated directly into a groundbreaking project: Edge.js , a JavaScript runtime that can run Node.js workloads for AI and edge computing.
