Engines and toolchains that execute JavaScript outside the browser, including their packaging, compilation and standard-library differences.
Cloudflare is acquiring the Deno team, with one year of bug and security fixes committed for the runtime. Anyone building on Deno now has to choose between migrating and backing a community fork.
Reality
Deno 2.9, released June 25, 2026, added an experimental deno desktop command that compiles a web app into a single binary. The default backend bundles no browser engine, so rendering follows WebView2 or WebKit. Bundling Chromium is a flag away, at tens of megabytes.
Reality
Deno's entire team is joining Cloudflare and taking celld, its open-source implementation of Workers and Durable Objects, along with it. For teams on Workers, the code they would use to leave now comes from the company they would be leaving.

Deno Deploy shuts down around April 2027 under Ryan Dahl's plan to move the whole Deno team to Cloudflare, a dev.to migration guide reports. Hosted apps must move by then; teams self-hosting Deno get a longer deadline set by the end of security releases.

Vercel Labs' experimental ScriptC compiles TypeScript to native binaries that started in 1.78ms against Node's 61.78ms in one benchmark. The gain holds for short, statically typed programs, while framework code and sustained compute both ran slower than Bun or Node.
Reality
Node.js marks type stripping Stable in versions 25.2 and 24.12, letting node script.ts run TypeScript without ts-node, tsx or a build step. Node only deletes types, so the switch holds for code that stays inside TypeScript's erasable subset.
Reality
Node.js will ship one major release a year from this October, dropping the odd-numbered line that few teams ran in production. LTS-only shops mostly see renumbering, and the cost lands on teams that took new APIs from the odd Current line.
Reality
The project's own download page lists its example music player at 7.4 MB against Electron's 150 MB floor, with native Node addons and identical cross-platform rendering among the costs of getting there.

Of the ten code migrations Anthropic says finished in a month, only one carries a dollar figure: 5.9 billion input tokens and 690 million output tokens, a million lines of Rust, about 16.5 cents a line.
Reality
Jarred Sumner's four-month rewrite checked transpiled Rust against a TypeScript suite that does not depend on the implementation language, and reaching a fully passing run cost about $165,000 in tokens.
Reality
Bun's port from Zig to Rust landed in four months because its test suite was written in TypeScript, independent of the language underneath, and because separate agents wrote the code and reviewed it.
Reality
Deno 2.6 added --min-dep-age to keep freshly published npm versions out of installs. Testing on 2.9.6 found that any duration carrying a month or year component drops the check entirely, with exit code 0 and an empty stderr.
Reality
The LTS patch also carries OpenSSL 3.5.8, six semver-minor additions including a faster net.BlockList, and three FIPS entries filed under one pull request, so the regression run costs more than a version bump usually does.
Reality
Size was the only reason to pick Tauri over Electron for this app, and the discount is real. What you take on in exchange is a second process whose lifetime and paths you now manage from Rust.
