RigHost Tool

The Compatibility Score, Explained

RigHost's checker gives you a score out of 100. This is how that number is calculated, what each category is actually testing, and how to read a result that says “needs some work.”

When you run the RigHost compatibility checker, you get a number between 0 and 100 and a status badge: Ready to Host, Needs Some Work, or Not Ready Yet. The score is a snapshot of how close your rig is to the Vast.ai host minimums, weighted by how much each category actually affects whether rentals happen.

This article lays out the full rubric so you can read your result with confidence and know which category to fix first if you land short.

The rubric

Six categories, 100 points total. The weights reflect how heavily each factor drives real-world rental demand:

CategoryWeightWhat it measures
GPU30NVIDIA vendor + VRAM amount
Internet25Upload and download speeds
Storage15Available free storage in GB
CPU / RAM10Logical CPU cores and system RAM
Operating System10Ubuntu 22.04 preferred, others partial
Docker10Docker installed and working

GPU (30 pts)

Internet (25 pts)

Scored on the lower of your upload and download speeds — both directions matter because renters upload datasets and download results.

If only one direction is provided, you get a partial score but the category is flagged as a warning.

Storage (15 pts)

CPU / RAM (10 pts)

Operating System (10 pts)

Docker (10 pts)

If you don't have Docker set up yet, see our Docker + NVIDIA setup guide.

The score thresholds

85-100 Ready to Host. Your rig meets the Vast.ai minimums across the board. Install the host agent and start listing.
60-84 Needs Some Work. One or two categories are short. Read the recommendations, fix what you can, re-run.
0-59 Not Ready Yet. A foundational piece is missing — usually the GPU, the OS, or internet speed. Address those first.

A worked example

Let's score a realistic mid-tier rig:

Scoring:

CategoryResultPoints
GPUNVIDIA, 24 GB VRAM30 / 30
Internetmin(800, 800) = 800 Mbps25 / 25
Storage1000 GB free15 / 15
CPU / RAM12 cores, 32 GB10 / 10
Operating SystemUbuntu 22.0410 / 10
DockerInstalled10 / 10
Total100 / 100

That rig scores 100 and lands in Ready to Host. Drop the internet to 150 Mbps and the total becomes 87 — still in Ready, but now with a recommendation to upgrade bandwidth for better utilization. Drop storage to 50 GB and the total becomes 75 — Needs Some Work, and the recommendation will tell you to free up or add disk.

Reading a "Needs Some Work" result

The recommendations panel at the bottom of the results is the actionable part. It tells you exactly what to change to move up a tier. Common patterns:

The score is a gating estimate, not a guarantee. Clearing 85+ means your rig meets the baseline requirements. It does not guarantee rental demand or earnings — that depends on marketplace supply and GPU tier. See our profitability article for the economics.

CLI vs browser wizard

The browser wizard and the CLI script (curl -sSL https://www.righost.com/check.sh | bash) use the exact same scoring rubric — the only difference is how inputs are collected. The CLI auto-detects values directly from the server, which is usually more accurate than browser self-reporting (browsers cap RAM detection at 8 GB for privacy and can't measure network speed). If you have shell access, prefer the CLI.
