Cut Vercel build times for Next.js App Router projects — measure per-phase from the build log, then attack page count, duplicated type checks, and dead Turbopack-era config. Use when deploys have crept past a few minutes, or before optimizing anything on a guess.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Vercel Build Speed (Next.js App Router) Derived from taking a real production Next.js 16 / Turbopack app from **7m21s to 3m46s**, measured per-phase on Vercel at every step. The single most useful lesson was epistemic: **the obvious lever was the wrong one.** Removing ~560MB of assets bought about 5 seconds. Cutting prerendered page count bought ~50. ## Calibration — this is one case study, not a benchmark Every number here comes from **one app, one Vercel plan, one 4-core / 8GB build machine**, in mid-2026 on Next 16.2. The app was a localized content site: four locales, ~2500 prerendered pages, a large `public/`, a 1.5GB git history. Weight the findings accordingly: **Likely to generalize** — the method (read the phase table, change one class of thing per deploy, re-attribute after each), the `vercel.json` failure mode, the Turbopack dead-config audit, and the *shape* of the ranking: compute and page count beat bytes. **Re-measure for your project** — every specific duration, and especially the three "myths". "Clone time is not proportional to tree size" and "Deploying outputs has a fixed floor" each rest on **two observations on one project**. …

How to install
mdr add augchan42/inkstone/vercel-build-speed@sha256:b12b17a1a3960407The line at the top of this page pins the label v1.0.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
