## The Hook

Deno is the MIT TypeScript runtime you can keep when Node tooling tax is the complaint.

## What's Good

MIT runtime forever. Secure-by-default permissions, built-in TypeScript, std library, npm interop matured. Deploy free tier is real. Skills already on the catalog; gem was missing.

## The Catch

Deploy is not the runtime. The MIT runtime is free forever; Deno Deploy is a separate hosted product with a free tier — do not conflate them. Distinct from Node and Bun as runtimes.

## Verdict

MIT runtime forever. Deploy free tier is real; do not merge the two.
