Web App Stack Comparison

Architecture
	React / Next.js	Ruby on Rails	Laravel (PHP)	Django (Python)
Pattern	Component-based SPA Frontend-only; needs separate backend [Backend required]	MVC monolith Full-stack in one app [Built-in]	MVC monolith Full-stack in one app [Built-in]	MVT monolith Model-View-Template; same idea [Built-in]
Rendering	Client-side (CSR) Next.js adds SSR/SSG but AI defaults to CSR	Server-side (SSR) Hotwire / Turbo for interactivity	Server-side (SSR) Blade templates; Livewire for reactivity	Server-side (SSR) Django templates; HTMX growing
API Layer	Next.js API routes or Express You build it yourself [You decide]	Built-in REST + API mode rails new --api for JSON-only [Built-in]	Built-in routing + API Laravel Sanctum for API auth [Built-in]	Django REST Framework De facto standard add-on [Add-on]
Database & ORM
	React / Next.js	Ruby on Rails	Laravel (PHP)	Django (Python)
ORM	Prisma or Drizzle You pick and configure [You decide]	ActiveRecord Convention-driven, tightly integrated [Built-in]	Eloquent ActiveRecord-style, fluent syntax [Built-in]	Django ORM Declarative models, powerful querysets [Built-in]
Migrations	Prisma migrate / Knex Varies by ORM choice [You decide]	rails db:migrate Versioned, reversible, generators [Built-in]	php artisan migrate Versioned, reversible [Built-in]	manage.py migrate Auto-generated from model changes [Built-in]
Default DB	PostgreSQL or MongoDB AI often suggests Mongo even when relational fits	SQLite → PostgreSQL SQLite dev, Postgres prod	MySQL / MariaDB PostgreSQL also well supported	SQLite → PostgreSQL Same dev/prod pattern as Rails
Authentication & Authorization
	React / Next.js	Ruby on Rails	Laravel (PHP)	Django (Python)
Auth Solution	NextAuth / Auth0 / Clerk / JWT AI often generates raw JWT setup [Must choose]	Devise Battle-tested gem; email, OAuth, 2FA [Gem]	Breeze / Jetstream Official starter kits with full UI [Built-in]	django.contrib.auth Built into framework core [Built-in]
Authorization	Manual middleware or CASL Often ad-hoc if/else checks [You decide]	Pundit or CanCanCan Policy objects or ability classes [Gem]	Gates & Policies First-class framework feature [Built-in]	Permissions + Groups Built-in; django-guardian for object-level [Built-in]
Frontend / UI
	React / Next.js	Ruby on Rails	Laravel (PHP)	Django (Python)
Styling	Tailwind CSS AI default; sometimes styled-components	Tailwind / Bootstrap / CSS Asset pipeline or import maps	Tailwind or Vite + CSS Vite bundling built into Laravel	Manual / any CSS framework No opinion; collectstatic for assets
Interactivity	Full client-side JS useState, useEffect, React Query — you manage all sync and cleanup	Hotwire (Turbo + Stimulus) HTML-over-the-wire; minimal JS	Livewire or Alpine.js Server-driven reactivity	HTMX or Alpine.js Growing ecosystem; not official
State Mgmt	useState / Redux / Zustand Client holds copy of server data that can go stale [Must choose]	Server owns state Session + DB; no client state [N/A]	Server owns state Session + DB [N/A]	Server owns state Session + DB [N/A]
Side Effects / Lifecycle	useEffect Data fetching, subscriptions, timers. Source of infinite re-renders, stale closures, race conditions. [Painful]	Not applicable Server renders on request; no lifecycle [Non-issue]	Not applicable Server renders on request; no lifecycle [Non-issue]	Not applicable Server renders on request; no lifecycle [Non-issue]
Data Sync	React Query / SWR / manual Client cache vs server DB must stay in sync; stale data, optimistic updates on you [Must solve]	Every request hits DB Always fresh; no sync problem [Non-issue]	Every request hits DB Always fresh; no sync problem [Non-issue]	Every request hits DB Always fresh; no sync problem [Non-issue]
Background Jobs & Email
	React / Next.js	Ruby on Rails	Laravel (PHP)	Django (Python)
Job Queue	BullMQ / custom / none Often missing from AI output entirely [Must add]	Active Job + Sidekiq Unified API, multiple backends [Built-in]	Laravel Queues Redis, SQS, DB drivers built in [Built-in]	Celery Powerful but separate setup [Add-on]
Email	Resend / SendGrid / Nodemailer You wire it up yourself [You decide]	Action Mailer Built-in with templates [Built-in]	Laravel Mail Mailables with Blade templates [Built-in]	django.core.mail Basic but functional [Built-in]
File Storage & Testing
	React / Next.js	Ruby on Rails	Laravel (PHP)	Django (Python)
Uploads	Multer / UploadThing / S3 Manual integration [You decide]	Active Storage S3, GCS, Azure, local — config only [Built-in]	Laravel Filesystem Flysystem abstraction [Built-in]	django-storages Add-on but nearly universal [Add-on]
Test Framework	Jest / Vitest / Playwright AI rarely generates tests at all [You decide]	Minitest or RSpec Generators included with scaffolds [Built-in]	PHPUnit / Pest First-class testing support [Built-in]	unittest / pytest TestCase built into framework [Built-in]
Admin & Deployment
	React / Next.js	Ruby on Rails	Laravel (PHP)	Django (Python)
Admin Panel	Build from scratch or Retool Nothing included [Must build]	ActiveAdmin / Avo Gems generate full CRUD admin [Gem]	Nova or Filament Nova paid; Filament free/OSS [Add-on]	django.contrib.admin Auto-generated from models [Built-in]
CLI / Generators	create-next-app only No model/controller generators	rails generate scaffold Model, migration, controller, views, routes, tests [Built-in]	php artisan make:* Models, controllers, migrations, policies [Built-in]	manage.py startapp App scaffolding; less granular [Built-in]
Deploy Target	Vercel / Netlify / Cloudflare Edge-optimized for static + serverless	Render / Fly.io / Heroku Needs long-running server process	Forge / Vapor / VPS PHP runs almost anywhere	Render / Railway / VPS WSGI/ASGI server
