Does Laravel Work With Fly.io?
Laravel deploys seamlessly to Fly.io with first-class support and excellent developer experience for running PHP applications globally.
Quick Facts
How Laravel Works With Fly.io
Laravel runs exceptionally well on Fly.io because Fly.io provides native support for PHP applications via its buildpack system and Docker containerization. Fly.io handles the deployment pipeline automatically—you define your app in a `fly.toml` configuration file, and the platform builds a Docker image from your Laravel project, manages your database connections (MySQL, PostgreSQL), and deploys instances across multiple regions. The developer experience is streamlined: you run `flyctl launch` in your Laravel project root, answer a few questions about your database and environment, and Fly.io generates the necessary configuration. Laravel's `.env` file maps naturally to Fly.io's secrets management, so sensitive data stays secure. The real power emerges from Fly.io's distributed architecture—your Laravel app runs close to users globally with automatic load balancing. Sessions, caching, and file storage need consideration though; Fly.io volumes provide persistent storage, while Redis add-ons handle distributed sessions elegantly. Most Laravel workflows (Artisan migrations, queues via background processes, scheduled tasks) work without modification.
Best Use Cases
Fly.io Configuration for Laravel
curl -L https://fly.io/install.sh | sh# Initialize your Laravel app on Fly.io
flyctl launch
# fly.toml (auto-generated, then modified)
[app]
kill_signal = "SIGTERM"
kill_timeout = 5
processes = {}
[[services]]
internal_port = 8080
protocol = "tcp"
hard_limit = 1000
[env]
APP_NAME = "laravel-app"
APP_ENV = "production"
[[services.tcp_checks]]
grace_period = "5s"
interval = "30s"
timeout = "5s"
# Set secrets for production
flyctl secrets set APP_KEY=$(php artisan key:generate --show)
flyctl secrets set DB_PASSWORD=$(openssl rand -base64 32)
# Deploy
flyctl deployKnown Issues & Gotchas
File storage persistence: Laravel's default local disk doesn't persist between deploys or across instances
Fix: Use Fly.io volumes for persistent storage or configure S3/cloud storage as your filesystem driver in config/filesystems.php
Session handling across regions: Default file-based sessions won't sync between geographically distributed instances
Fix: Configure Redis for sessions in config/session.php and add a Redis database using Fly.io managed databases
Database connection pooling: Direct connections can exhaust under high concurrency on distributed deployments
Fix: Use PgBouncer for PostgreSQL or configure connection pooling in your database layer
Artisan commands and migrations run on the first instance only by default
Fix: Use `flyctl ssh console` to access the release VM and manually run migration commands, or automate via release_command in fly.toml
Alternatives
- •Laravel Forge + DigitalOcean App Platform: Forge handles server provisioning while App Platform provides managed deployment
- •Laravel Vapor + AWS: Serverless deployment with auto-scaling, best for event-driven workloads
- •Docker + Kubernetes (EKS/GKE): Maximum control and portability, higher operational complexity
