A bug I found in my own tool: bun had 2 known advisories, rspack core had 1, but both were missing from the package map, so bundleferry stayed silent. A Bun project got reported clean when it was not. A security check that quietly does not run is the worst.

A quiet lie in security tooling: ask OSV about a package with no version and it returns every advisory ever filed, most long fixed. For next that is 55. Pin the declared version and it is the 25 that actually apply. bundleferry pins it.

I was going to build a JS bundler faster than all of them. Then I measured: a real Vite build is 510ms. Twice as fast saves 255 milliseconds. Bundler speed is not the bottleneck, so I built a migration advisor instead.

How do you trust a tool that says a claim is verified? I broke my own verifier so it accepted every hallucinated claim, then ran the tests. Exactly 7 failed, the 7 that guard the gate. A harness that cannot fail proves nothing.

bundleferry --advise recommends a bundler and reports its security posture from OpenSSF Scorecard and OSV. Deterministic rules with citations, never an invented score. Every claim is checked by an independent verifier.

bundleferry is a Claude Code skill and a zero-runtime-dependency TypeScript CLI. 54 tests, CI green on Node 20, 22 and 24. It plans and measures, it does not silently rewrite your repo. The mechanical steps you apply and build to verify. MIT.
React Native and Expo: Metro is the only officially supported bundler. bundleferry will not auto-migrate it, but it names Re.Pack, the one real webpack and Rspack based alternative, and warns that adopting it leaves the supported Expo config.

Migrating a Next.js app to a Vite SPA is not a bundler swap, it is throwing away per-route SSR. bundleferry refuses to fake that. SSR, SSG and React Native are routed away with real alternatives, never silently converted to a green build that behaves wrong.

Study case: rapira, Bun to Vite. The whole migration was one word. Bun emits a worker file side by side, so the source said new URL('./worker.js'). Vite resolves workers from source, so it becomes './worker.ts'. bundleferry names gotchas like this first.

Study case: foody-monk, Parcel to Vite. The only one of six that got smaller, 139 to 127 KB gzip, because the app used React.lazy and Vite honored the code splitting Parcel had flattened. Every rule in bundleferry came from a real migration like this.

bundleferry plans a migration between ANY pair of JS bundlers: 14 sources times 7 targets, no dead cells. webpack, CRA, Rollup, Parcel, esbuild, Snowpack, Gulp, Rspack, Vite, Bun and more. Three tiers: green auto, yellow confirm, red decide.
