OpenClaw VPS Specs
Minimum vs Recommended
Exactly how much RAM, CPU, and storage you need — broken down by what you’re actually doing with your agent.
RAM Is Everything
CPU and storage matter, but RAM is the single most important spec for OpenClaw. Here’s what each tier gets you.
The Gateway, Agent, and Docker runtime together consume ~1.5–2 GB at idle. Each active browser automation session (Chromium) adds 1–2 GB on top. If your VPS runs out of RAM, OpenClaw doesn’t slow down — it crashes and stops responding until you restart it.
Specs by What You’re Actually Doing
Stop guessing. Match your use case to the right server size.

OpenClaw’s Memory system reads and writes SQLite databases and Markdown files constantly. NVMe SSD is 3–5× faster than standard SSD for these small random I/O operations. It directly impacts how quickly your agent responds to requests. Always choose NVMe if available — Hostinger includes it on all plans.
