Steam Analyser

Steam Analyser is a free diagnostic tool for game developers and marketers working with Steam store pages. You paste your Steam store URL — or simply upload a capsule image if your page is not live yet — and the tool returns a 0-100 score, a six-dimension breakdown, a small-thumbnail render test and a ranked list of specific fixes. There is no account, no email gate and no paywall; results come back in seconds.

The evaluation is grounded in a specific and fairly well-known problem: the capsule is the most-seen piece of marketing art most games will ever ship, and Steam shrinks it to a 120×45 thumbnail in search and discovery, which is where most impressions happen. The six scored dimensions are genre clarity, title readability, contrast and colour, uniqueness and polish, brand consistency, and composition, each judged at full, small and tiny sizes. Your 0-100 score is the average of the six, times ten, and the full rubric is published on a methodology page.

The tool is published by Immutable, a company that builds growth, attribution and audience products for game studios, and the site states that more than 25,000 unique Steam pages have been analysed. It is positioned as an honest, free entry point rather than a paid product — the analysis tells you what is wrong with the capsule, but the actual redesign work, and everything downstream of the click such as screenshots, trailer and description, remains your job.
