GreaseGet greased.

Opt-in performance for Laravel's hot paths. One trait, byte-identical output, real requests measurably faster — end to end. Built from optimizations declined upstream, packaged where you can opt in.

Why Grease?

🧈

One trait. That's the install.

Add `use HasGrease;` to a model and its hot paths get faster. No config, no migration, no framework patch. Leave every other model untouched.

🪞

Byte-identical output

Asserted across every cast type, edge value, and dirty-check in the parity suite. Same bytes as vanilla Eloquent — or it's a failing test. That promise is the whole product.

⚡

Per-op wins that stack

hydrate −53% · toArray −53% · set+dirty −44% · read −31% · enum cast −58% · date serialization −92%. Marginal in isolation; compounded on a real request, they aren't.

📦

Real requests, end to end

Big end-to-end deltas on in-memory workloads (−20% to −74% across list, eager-load, mutate-save, show) — SQL included, not a micro-benchmark. Read them as Grease's share of the ORM work; the portable figure is the absolute time removed.

🔌

Beyond Eloquent

A drop-in faster event dispatcher (−53% on no-listener dispatch) speeds up every dispatch app-wide — model events, views, cache, your own events.

🧩

Zero framework changes

Non-greased models run pure vanilla Eloquent — Grease adds zero cost to anything that doesn't opt in. PHP 8.2+, Laravel 12 / 13.

The whole install

php

use Grease\Concerns\HasGrease;

class User extends Model
{
    use HasGrease; 
}

That's it. Eloquent re-derives the same class-pure facts on every attribute access and every hydrated row — rebuilding the casts array, re-walking a cast switch, re-probing method_exists for mutators, re-resolving the date format, running a fresh ReflectionClass per new Model. None of it changes for the life of the class. Grease computes each fact once per class and reuses it.

Each of these was proposed to Laravel core and declined on reasonable grounds — every one "marginal in isolation." Individually, maybe. Bundled, on a request that hydrates a hundred rows and serializes them to JSON, they move the number you actually pay for. Grease is where that declined work lives — see the history.
