Plausible is a privacy-focused, open-source analytics tool that provides website traffic insights without compromising user data. When self-hosting Plausible on a Virtual Private Server (VPS), selecting the right specifications is critical for performance, scalability, and cost-efficiency. This guide covers the minimum and recommended VPS requirements for Plausible, focusing on RAM, CPU, and storage needs. Whether you are using a low-cost VPS or planning for high traffic sites, understanding these specs will ensure a smooth deployment.
Understanding Plausible Server Requirements
Plausible’s architecture is designed to be lightweight and efficient, making it suitable for modest VPS environments. Its resource consumption depends on several factors:
- Number of websites monitored
- Monthly traffic volume
- Data retention period
- Number of concurrent visitors
It is crucial to balance these factors when choosing your VPS specs to prevent performance bottlenecks.
Minimum and Recommended VPS Specifications
Based on Plausible’s resource behavior and community feedback, here are the general guidelines:
| Specification | Minimum Requirement | Recommended | Notes |
|---|---|---|---|
| RAM | 1 GB | 2 GB | For small sites (<100k page views/month) |
| CPU | 1 vCPU | 2 vCPUs | To handle concurrent requests smoothly |
| Storage | 10 GB SSD | 20 GB SSD | For logs, database, and system files |
Note: These are baseline figures. Larger traffic or multiple sites require proportionally higher specs.
Why RAM Matters for Plausible
RAM is critical because Plausible runs as a Node.js application with a PostgreSQL database backend. Insufficient RAM leads to swapping, causing latency and degraded user experience.
- Minimum RAM (1 GB) is suitable for a single small site with low traffic.
- Recommended (2 GB or more) is advised for handling multiple sites or higher traffic, ensuring database caching and app performance.
Tip: Monitor your server’s memory usage with tools like htop or free -m during peak traffic to adjust accordingly.
CPU Considerations
While Plausible is designed to be lightweight, the CPU influences the ability to process requests and generate reports:
- Single vCPU suffices for low-traffic sites (<50k page views/month).
- For higher traffic sites (>100k page views/month), at least 2 vCPUs improve responsiveness, especially during data aggregation or report exports.
Multiple sites or automations demand more CPU capacity to prevent bottlenecks.
Storage Needs for Plausible
Storage is primarily used for:
-
PostgreSQL database files
-
Log files
-
Application code and dependencies
-
A 10 GB SSD patch is the minimum, sufficient for small to medium setups.
-
20 GB or more provides headroom for growth, longer data retention, or multiple sites.
Pro tip: Use SSD storage from your VPS provider for better I/O performance, which impacts database responsiveness.

Additional Optimization Tips
- Database tuning: Adjust PostgreSQL parameters for your workload (e.g., shared buffers, work mem).
- Caching: Use Nginx or other reverse proxies with caching layers to reduce server load.
- Scaling: For larger sites, consider load balancers and multiple VPSs.
FAQs
What is the minimum RAM needed to run Plausible effectively?
The minimum RAM for running Plausible on a single-site setup with low traffic is 1 GB. However, for better performance and future growth, 2 GB is recommended. This ensures that the Node.js app and PostgreSQL database operate smoothly without swapping, especially under peak load. Monitoring RAM usage during busy periods helps you decide if an upgrade is necessary. For multiple sites or higher traffic, plan for additional RAM accordingly.
Can I run Plausible on a lower-spec VPS than recommended?
While it is possible to run Plausible on a VPS with specs below the recommended thresholds, it may lead to performance issues, especially during high traffic or database queries. The minimal specs are suitable for experimental or very small sites with low traffic. For production environments, sticking to or exceeding the recommended specs ensures stable operation and good user experience. Always monitor resource utilization and scale as needed.
How does storage size impact Plausible’s performance?
Storage primarily affects how much historical data and logs you can retain. Insufficient storage may lead to database or log file errors, causing downtime or data loss. Using SSD storage is crucial for maintaining fast database responses. For small sites, a minimum of 10 GB is sufficient, but for multiple sites or long data retention periods, 20 GB or more provides ample buffer. Regularly archive old data if necessary to manage storage growth.
