Our Commentary ​

Wow. Just... wow. Deno joining Cloudflare is big, but the news that Cloudflare will stop maintaining the Deno runtime after a year is a gut punch. Ryan Dahl's explanation about the "gravity well of Node compatibility" is brutally honest, and I get it. It's a tough spot to be in, trying to innovate while constantly being pulled back to Node.js parity. This feels like a definitive end to the "Node.js killer" narrative, and a clear pivot towards Cloudflare's workerd vision. I'm genuinely sad for the Deno community, but also intrigued by what celld might become.
