#Deno

Fresh 2.3 makes the 'zero JavaScript by default' promise a hard reality, adds native View Transitions, introduces built-in WebSocket handlers, CSP nonce injection, and Temporal API support for islands.

Nitro's latest beta adds support for custom framework preview and deploy commands, introduces a defaultPreset config option for customizing the fallback preset, and fixes a type-stripping edge case.

Deno 2.8 drops with four new CLI subcommands, improved Node.js compatibility, and a Rust-based package packager targeting npm registries.

Deno 2.7 is a substantial mid-cycle release: the Temporal API is now production-ready, native Windows on ARM builds land, npm overrides work like in Node, and dozens of Node.js compatibility improvements land across worker_threads, child_process, zlib, and sqlite.

Three JavaScript runtimes. Three different philosophies. Independent benchmarks across HTTP throughput, cold starts, and async performance tell a clearer story than marketing ever could. Here's the brutally honest breakdown for developers choosing their next server-side JS platform.
