How much RAM does Laravel need on a VPS?

Minimum and Recommended RAM for Laravel

Laravel itself is a lightweight PHP framework, but its performance and stability on a VPS depend heavily on available memory. At HostingDuty, we observe that a bare-minimum setup can run on 512MB of RAM, but this leaves little room for error or growth. For most production workloads, we recommend starting with 1GB to 2GB of RAM to ensure smooth operation under load.

Baseline Requirements

A fresh Laravel installation with a single PHP-FPM worker, a lightweight web server like Nginx, and a small MySQL or MariaDB instance can operate within 512MB. However, this configuration is fragile. Any spike in traffic or background job execution can trigger OOM (Out of Memory) kills, causing downtime. For a stable environment, we advise allocating at least 1GB of RAM.

Production Workloads

In production, Laravel applications often run additional services that consume memory:

• Queue workers (e.g., for sending emails or processing uploads)
• Caching layers (Redis or Memcached)
• Database processes (MySQL/MariaDB buffer pools)
• Monitoring and logging tools

Each of these adds overhead. For example, Redis alone can consume 100–300MB depending on cache size. A typical Laravel app with queues and caching should have at least 2GB of RAM. If you're running multiple worker processes or using heavy packages like Laravel Scout or Horizon, consider 4GB or more.

Monitoring and Optimization

We recommend using tools like htop, free -m, or HostingDuty's built-in monitoring to track memory usage. You can also tune PHP-FPM settings to limit worker count and memory per process. See our guide on PHP-FPM configuration for detailed steps.

Scaling Considerations

As your application grows, so should your VPS resources. If you notice frequent memory spikes or slow response times, consider upgrading your plan or optimizing your codebase. HostingDuty offers scalable VPS plans that allow you to increase RAM without downtime. Learn more about VPS resource allocation in our knowledge base.
