Steam Page Analysis Tools in 2026: 7 Checked, 4 That Grade

I checked seven Steam page tools on 14 September 2026, and four of them actually grade a store page or its capsule: Steam Page Analyzer (ours), Immutable’s Steam Analyser, Navfuse, and Steamkit. Three of those four are free to run with no account. The fourth will not show a logged-out visitor its prices at all.

The rest of this post is what each tool states on its own page, on that day. What is free, whether it wants an email, which parts of your page it scores, whether it works before you have a store page, what any paid tier costs, and whether the vendor publishes a method. Where a page does not say something, the cell reads “not stated” instead of a guess. Two of the seven, CapsuleGrader and StraySpark, did not answer our requests at all that day, and one, gamedo.live, turned out to have no tool in it. Those three get a section rather than a row, because a row implies I read something I did not read.

Read on 14 September 2026, from each vendor’s own page. Nothing here is inferred.

Two cells in that table are the whole story of this category in 2026. Immutable is the only one publishing the rubric it scores you against. Steamkit is the only one that hides its price behind a login.

Ours, so here it is flat. Paste a public Steam store URL into the free analyzer and you get an overall score, four category scores for capsule, description, screenshots and tags, your top issue written out with its fix, and a count of how many other issues were found. Three runs a day, no account. Coming Soon and Early Access pages work; the page has to be public for the analyzer to read it.

The paid side is one product: a $29 Full Report for that game, which unlocks every issue with its fix, the prioritized recommendations, paste-ready page changes, the deep dives, the competitor comparison, the buyer journey walkthrough, score history with 2 re-runs included, and a PDF. There is also a $499 Studio Launch Pack covering up to 10 games. That is the entire price list.

What we do not do: score art you have not uploaded to Steam yet, and publish the rubric as a document you can audit. On that second one Immutable is ahead of us, and the rest of this post says so plainly.

If you type steamanalyser.com you no longer land on a standalone site. As of 14 September 2026 the apex 307s to www, www 308s to immutable.com/resources/free-steam-tools/steam-capsule-analyzer?ref=steamanalyser, and that is where the tool lives. Immutable’s free Steam tools hub lists six of them and says “No signup for any of them.”

The analyser scores one asset, the capsule, on six dimensions: genre clarity, title readability, contrast and color, uniqueness and polish, brand consistency, composition. Each starts at 6, “the competent baseline”, moves on evidence in the art, and the six are averaged and multiplied by ten for the 0-100 number. That formula is on a methodology page whose version line reads “Methodology v1”, reviewed 2026-07-02, which is more than anyone else in this comparison publishes, us included.

Two things it does that nothing else here does. First, the honesty of the gate: “No account, no credit card, no 'enter your email to unlock your score’.” Second, and this is the one that matters most: it scores art with no store page at all. Its own FAQ: “Can I use this before my Steam page is live? Yes. Upload the art directly and you’ll get the same six-dimension score and ranked fixes with no store page required.” If your capsule is a file in a folder and your Steam page does not exist yet, this is the tool to use. Ours cannot help you yet, and neither can the other two.

The limits are just as plain. It reads the capsule, not your screenshots, not your description, not your review signals. The tag audit is a separate tool on the same hub (“an audit of all 20 tag slots against a 725-game top-seller corpus”). And the free tools are the front of a paid growth platform whose own price is nowhere on the site: the call to action is Book a demo, and the footer says “Trusted by 700+ games”. If you want the full head to head, we wrote Steam Page Analyzer vs Immutable’s Steam Analyser.

Navfuse’s AI Steam Page Analyzer asks you to pick an AI provider before you can run anything, under a heading that reads “API Key Setup (Required)”. Pick its OpenAI option and you get “up to 3 Steam pages per day for free using GPT-4o mini”, with a visible counter that resets every 24 hours UTC. Pick Gemini and you paste your own key, which the page says takes 60 seconds with no credit card, and the daily cap goes away.

That second path is the interesting one and it is genuinely generous: unlimited runs, and you pay whatever your own key costs, which for a handful of page analyses is close to nothing. If you already have a Gemini key, Navfuse is the cheapest way in this list to run a page grade over and over while you iterate.

What the page will not tell you is what it grades. The copy says “an instant AI analysis with a grade on every section of your page” and the output blocks are Overall Score, Key Findings, Fix This First and Detailed Analysis, but no section list appears anywhere before you run it. The site’s own structured data describes it as grading “your title, description, visuals, tags, and more”, which is a description of intent rather than a rubric. Input is a store URL only, so there is no pre-launch path. No price is stated, and none appears to exist.

Steamkit’s Steam Page Analyzer takes an App ID or a store URL and promises “AI-powered insights to improve your Steam store page”. It sits in a suite alongside a capsule generator, a localization tool, a store simulator, a capsule resizer, a press kit builder and a revenue calculator, which is the broadest tool set of anyone here.

Then you try to work out what it costs. The home page banner says “Claim your free daily credits! Click here to get your credits for today” without naming an amount. The FAQ says “SteamKit offers a free tier with limited credits to get started” and that “Each tool or operation consumes a certain number of credits”, again without an amount. And steamkit.dev/pricing redirects a logged-out visitor to /login, which returned a 404 when I checked it. So the honest cell in the table is not a dollar figure and not “free”. It is “not published to a logged-out visitor”.

For a developer comparing options in an afternoon, that is a real cost. You cannot price it without signing up, and you cannot tell what the analyzer scores without spending a credit to find out.

CapsuleGrader. Every request from this network to capsulegrader.com timed out at the TCP layer on 14 September 2026, across five attempts and four URLs. DNS resolves and the domain has live mail records, so this is a connection problem between us and the host rather than evidence the tool is down. I am not going to quote a search snippet as though I read the page. Open it yourself before you judge it, and treat its absence from the table as our failure to reach it, not a verdict.

StraySpark. Same outcome, same day: nothing loaded. The only StraySpark tool URLs that exist are a launch planner and a revenue and wishlist tracker, so on the evidence available it belongs with the planners and calculators rather than the page graders. If you want the calculator category done properly, our revenue calculator is free and instant.

gamedo.live. Checked, loaded fine, and it is not a tool. It is an indie games news and reviews site with a Dev Corner section of tutorials. Searching the rendered page for “tool”, “analyz”, “calculator” and “capsule” returned nothing outside a Steam image URL. Good site, wrong list.

Match the situation to the row. Two of these four answers are not us, and that is the correct answer in those two cases.

• •Your capsule exists but your Steam page does not. Immutable’s Steam Analyser. It is the only tool here that takes an uploaded image with no store page, it is ungated, and its rubric is published so you can argue with it. Nothing we sell competes at this moment in the timeline.
• •You want to iterate on a page twenty times this week. Navfuse with your own Gemini API key. Unlimited runs at your own token cost beats every daily cap in this comparison, including ours.
• •You have a public page and you want the whole page read, not just the art. Our free analyzer scores capsule, description, screenshots and tags and names your top issue at no cost. If you then want every issue and its fix, that is the $29 report.
• •You want a capsule generator, a resizer and a localizer in one login. Steamkit has the widest tool set here. Accept that you will sign in before you can see a price.
• •You want to know if your capsule reads at thumbnail size before any AI sees it. Skip the graders entirely and run the capsule validator, which checks your art against Steam’s size requirements in the browser. Then read the capsule design guide for what to change.

One habit worth keeping whichever you pick: write the date next to any score you record. Every tool in this comparison changes its rubric without announcing it, and a 74 in September is not comparable to a 74 in March.

Every tool above reads your public store page. Not one of them can see a single one of your own numbers. Your impressions, your click-through rate, your visit-to-wishlist conversion and your campaign attribution live inside Steamworks and nowhere else, and they are free to you already. Valve’s traffic reporting documentation describes the breakdown by source, and our CTR benchmarks give you numbers to compare against.

So the split is clean. A page grader answers “is my page any good?” Steamworks answers “how many people saw it and what did they do?” A beautiful page with no traffic and a busy page that converts nobody fail for opposite reasons, and mixing up the two questions is the most common mistake I see in this whole category.

If what you actually want is competitor sales and revenue rather than page quality, that is a different shelf entirely: SteamDB vs SteamSpy vs VG Insights vs Gamalytic covers the estimate tools, and Gamalytic alternatives covers what to do when the estimate has a price on it. When the page itself is the problem, the Steam page optimization guide is the systematic way through it.

What is the best free Steam page analysis tool in 2026?

It depends on what you have. If your Steam page is live, our free analyzer scores capsule, description, screenshots and tags and names your top issue with no account, three runs a day. If you only have capsule art and no store page yet, Immutable’s Steam Analyser is the better tool, because it accepts an uploaded image, asks for no email, and publishes the six-dimension rubric it scores against. If you want unlimited runs, Navfuse with your own Gemini API key removes the daily cap. All three were free to run on 14 September 2026.

Do any Steam page analyzers work before my store page is live?

One of the four checked does. Immutable’s Steam Analyser states: “Upload the art directly and you’ll get the same six-dimension score and ranked fixes with no store page required.” Steam Page Analyzer, Navfuse and Steamkit all need a store URL or App ID, so they need a public page first. Coming Soon pages count as public, so you do not have to wait for release, only for the page.

Do these tools need my email address?

Immutable’s tool states “No account, no email gate”. Steam Page Analyzer gives you the free score with no account, three runs a day. Navfuse does not state an account requirement, but it does require you to select an AI provider before running. Steamkit runs on credits that attach to an account, so in practice you sign in. Checked 14 September 2026.

How accurate are Steam page analyzer scores?

Nobody in this comparison publishes an accuracy study of their page grade, and that includes us. Immutable publishes its rubric, anchors and formula, which lets you check whether a score follows from the art, but that is transparency rather than accuracy. Treat any page score as a structured second opinion, fix what it flags, and then watch your own Steamworks traffic and conversion numbers to see whether the fix did anything.

What does the $29 Steam Page Analyzer report include?

Every issue found on your page with its fix, prioritized recommendations, paste-ready page changes, the deep dives, a competitor comparison, the buyer journey walkthrough, score history with 2 re-runs included, and a downloadable PDF. It is one payment for one game, not a subscription. The free score stays free whether you buy or not.
