The alternatives below are ranked the same way, so you're comparing real release momentum, not marketing claims.
About Deno
Deno expands from runtime to platform — desktop apps, agent firewalls, and managed deploy
Deno is pushing well past its runtime roots into a full platform. Recent moves include deno desktop for building native apps from web tech, Claw Patrol (an open-source security firewall for AI agents), the general availability of Deno Deploy, and Deno Sandbox for running untrusted code in instant microVMs. The core runtime keeps shipping fast — Deno 2.7 through 2.9 added Temporal, new subcommands, framework-aware compile, and ongoing Node.js compatibility.
