What's Good
MIT (JSC linked). Runtime, package install, test runner, and bundler in one binary. Node-compat target with speed as the pitch. Joined Anthropic; OSS stays MIT.
The Catch
Node-compat is not 100%. Joined Anthropic — watch ecosystem/governance noise, but license remains MIT. Not Deno. Some packages still assume Node quirks.
Verdict
MIT JS toolkit. Free forever; Node parity is the real catch.
