Paperless-ngx is a powerful open-source document management system that allows users to capture, index, and manage documents efficiently. Hosting it on a Virtual Private Server (VPS) can provide the control and flexibility needed for a self-hosting environment. However, understanding the specific resource requirements is crucial for optimal performance. This guide outlines the essential server specifications needed to run Paperless-ngx effectively.
Minimum System Requirements
Before diving into the specifics, let’s first lay out the minimum system requirements for getting started with Paperless-ngx:
- RAM: 2 GB
- CPU: 1 vCPU
- Storage: 20 GB
These specifications are suitable for small installations or trial setups. However, as your usage grows—especially if you’re planning to handle multiple users or large files—it’s essential to scale your resources accordingly.
Recommended System Specifications
To ensure a smooth and efficient experience, especially in a production environment, consider the following recommended specifications:
- RAM: 4 GB or more
- CPU: 2 vCPUs or more
- Storage: 40 GB SSD or more
Using these specs will provide a better performance, allowing Paperless-ngx to handle concurrent requests and larger document loads more efficiently.
Understanding RAM, CPU, and Storage Specifications
To make an informed decision, let’s break down what each of these components contributes to the overall performance of Paperless-ngx.
RAM
- Minimum RAM (2 GB): This is the absolute baseline. While it may suffice for initial testing, you will likely experience slow performance if multiple users need to access the system simultaneously or if you are dealing with larger documents.
- Recommended RAM (4 GB): This allows for smooth operation with multiple users and provides additional resources for the database and web application to function without hiccups.
CPU
- Minimum CPU (1 vCPU): A single virtual CPU can handle light workloads, but as you increase the number of users or documents, you might face bottlenecks.
- Recommended CPU (2 vCPUs): Two virtual CPUs provide better distribution of processing power, crucial for handling the document parsing and indexing tasks that Paperless-ngx undertakes.
Storage
- Minimum Storage (20 GB): This will fill up quickly based on the size and number of documents, especially if using high-resolution scans.
- Recommended Storage (40 GB SSD): Solid State Drives (SSD) are preferred, as they significantly improve the speed of data access compared to traditional hard drives, which is essential for rapid document retrieval.

Frequently Asked Questions
What is the minimum RAM required to run Paperless-ngx efficiently?
Paperless-ngx can technically run with 2 GB of RAM, but this is not recommended for typical use cases. In practice, if you’re operating in a production environment or expect more than a few concurrent users, 4 GB of RAM is advisable. This will provide a buffer for the application, allowing it to process requests efficiently without becoming sluggish. If you’re looking to handle large documents or multiple users, consider even increasing RAM beyond 4 GB for future scalability.
Can I use a cheaper VPS plan for Paperless-ngx?
Yes, you can start with a cheaper VPS plan if you stick to the minimum specs. Providers like Hetzner Cloud offer plans as low as 5.49 EUR/month with 4 GB of RAM and 2 vCPUs, which already meets the recommended specification. The binding constraint at that tier is disk rather than memory: 40 GB fills up quickly once you archive scanned documents, so budget for an attached volume or a larger plan as the archive grows.
How much storage should I allocate for documents in Paperless-ngx?
For basic functionality, 20 GB of storage is sufficient, but this is a bare minimum. If you plan to store a significant amount of data, you should consider 40 GB or more. Engaging in larger document storage will also benefit from SSD drives, as they provide faster access times, significantly reducing the loading and retrieval times for documents. It’s also wise to consider future growth; always plan for more storage than you currently need.
By understanding the critical specifications needed to host Paperless-ngx and analyzing the available VPS options, you can ensure that your self-hosted instance runs smoothly and efficiently, catering to your development or homelab needs.
