Deploying Windmill, an open-source self-hosted platform for managing and deploying static sites and web apps, requires a clear understanding of VPS specifications. Whether you’re setting up a development environment or a production server, selecting the right VPS ensures smooth operation, scalability, and cost-efficiency.
This guide covers the essential Windmill server requirements, including RAM, CPU, and storage, and offers practical recommendations for choosing VPS providers that meet these specs.
Understanding Windmill’s System Requirements
Windmill is designed to be lightweight but flexible, capable of running on modest VPS hardware while scaling to more robust setups for larger workloads. The key components influencing server performance are:
- Memory (RAM)
- CPU cores
- Storage capacity
- Network bandwidth (optional for some use cases)
Knowing the minimum and recommended specifications helps prevent performance bottlenecks and future-proofs your setup.
Minimum Windmill VPS Specs
For basic operation - development, testing, or small projects - the minimum VPS specifications are:
- RAM: 2 GB
- CPU: 1 vCore
- Storage: 20 GB SSD
- OS: Linux (Ubuntu 20.04 LTS or newer recommended)
While these minimums may suffice for small-scale use, larger or more active deployments will benefit from higher specs.
Recommended Windmill VPS Specs
For production environments, or when hosting multiple sites and integrations, the following are more suitable:
- RAM: 4 - 8 GB
- CPU: 2 - 4 vCores
- Storage: 50 - 100 GB SSD
- Network: 100 Mbps or higher
These specs ensure that Windmill can handle concurrent builds, deployments, and larger asset loads efficiently.

Practical Recommendations
- For small projects or testing: A VPS with 2 GB RAM, 1 vCore, and 20 GB storage suffices. Providers like Hetzner Cloud or DigitalOcean can deliver this at low cost.
- For production or multi-site deployments: 4 to 8 GB RAM, 2 to 4 vCores, and at least 50 GB SSD storage are advisable. Contabo’s 5.99 EUR plan or Hetzner’s offerings are excellent options.
- Scaling considerations: Windmill’s infrastructure scales well with increased resources - consider gradually upgrading as your site complexity grows.
FAQs
What is the minimum RAM required to run Windmill?
The minimum RAM recommended for Windmill is 2 GB. This allows basic operation and development environments. For production deployments involving multiple sites or large assets, 4 GB or more is preferred to ensure responsiveness and stability, especially when running several processes concurrently.
Can I host Windmill on free or very cheap VPS providers?
While technically possible, hosting Windmill on extremely low-cost or free VPS may lead to performance issues due to insufficient RAM and CPU resources. For reliable operation, it is advisable to choose providers like Hetzner Cloud or Contabo, which offer affordable plans with the necessary specs. Cheap VPS often lack SSD storage and sufficient bandwidth, affecting site load times and deployment speed.
How much storage does Windmill require?
Windmill itself requires at least 20 GB of SSD storage for a minimal setup, including the operating system, the platform, and some static assets. For larger projects with multimedia assets or multiple sites, 50 GB or more is recommended. Ensuring SSD storage is critical for fast build times and site serving.
Conclusion
Optimizing Windmill server performance hinges on selecting a VPS with adequate RAM, CPU, and storage. For small projects, modest plans like those from Hetzner or DigitalOcean suffice. For larger deployments, consider plans from Contabo or Hetzner offering more resources at competitive prices.
Always choose VPS providers with SSD storage and good network performance to ensure fast builds and site delivery. When in doubt, consult the full VPS comparison to find the best fit for your Windmill self-hosting needs.
By aligning your VPS specs with Windmill requirements, you ensure a smooth, scalable, and efficient self-hosted environment that grows with your projects and team.
