v0.1.1 — now on npm

Your Pterodactyl build
in under 90 seconds.

pterospeed analyzes your webpack config, finds what's slowing it down, and fixes it — automatically, with a diff preview and backup before touching anything.

$ npx pterospeed@latest .

no install required · Node 20+

The problem

5 minutes every build.
Every. Single. Time.

The default webpack config that ships with Pterodactyl Panel was written to work, not to be fast. Every build starts from zero and pays the full cost.

✗ Memory-only webpack cache — lost after every process

✗ Babel re-transpiles unchanged files on every run

✗ TerserPlugin minifying even in development builds

✗ source-map-loader scanning all of node_modules

How it works

Two commands. Done.

1 — analyze your config

pterospeed analyze

$ npx pterospeed@latest .

✔ Detected: Pterodactyl Panel

✔ Root: /var/www/pterodactyl

Scanning build configuration...

⚠ Filesystem cache missing (high)

⚠ babel-loader cache missing (high)

⚠ source-map-loader scans too wide (medium)

⚠ TerserPlugin still in production path (medium)

⚠ minimize: true always runs (medium)

Build Health: 20 / 100 Critical

2 — apply the fixes

pterospeed optimize

$ pterospeed optimize . --preset aggressive

✔ Applied 5 optimization(s).

- Switched webpack cache to filesystem.

- Enabled babel-loader disk cache.

- Excluded node_modules from source-map-loader.

- Replaced TerserPlugin with EsbuildPlugin.

- minimize: true → minimize: isProduction.

› Production minification: ~3-4x faster

› Warm dev builds: ~5-10x faster

› Dev builds skip minification (~30-60s saved)

Optimizations

What gets fixed

Optimization	Preset	Expected gain
Webpack filesystem cache	safe	Warm builds 5–10× faster
babel-loader disk cache	safe	Cold builds ~20–30% faster
Scope source-map-loader	safe	Skips node_modules map parsing
Explicit CPU parallelism	safe	Full core utilization
minimize: isProduction	safe	Dev skips minification (~30-60s)
EsbuildPlugin (prod)	aggressive	Production minify 3–4× faster

After aggressive preset: run yarn install in your panel to install esbuild-loader.

CLI

All commands

pterospeed analyze [path] Scan config and report score

pterospeed optimize [path] Diff → confirm → apply fixes

pterospeed optimize --auto Skip confirmation prompt

pterospeed optimize --dry Show diff only, write nothing

pterospeed optimize --preset aggressive Also swap TerserPlugin → EsbuildPlugin

pterospeed benchmark [path] Measure cold / warm / production builds

pterospeed revert [path] Restore last backup

Stop waiting for builds.

Run it right now — no install, no config, no risk. Backup created before touching anything.
