I'm the Product Manager for the Internal Tools team here at Cloudflare. We recently identified a need for a new tool around service ownership. As a fast growing engineering organization, ownership of services changes fairly frequently.
Today, we're open sourcing and announcing wrangler, a CLI tool for building, previewing, and publishing Rust and WebAssembly Cloudflare Workers. If that sounds like some word salad to you, that's a reasonable reaction.
