What’s new

Every feature that has shipped, newest first. StreamArbitrage is built in the open and changes most weeks.

  1. What each session earned, against what the room said at the time

    The dashboard could only put today’s score beside a session you streamed last week, and said so in a footnote. Now the room score is written onto each session at the first reading where the category has one — usually within fifteen minutes of going live — and the dashboard plots your Twitch follower count session by session, coloured by it.

    • A chart of your Twitch follower count at every session since you started, one point per session — its size is the hours you streamed, its colour is how much room the category had at our first scored reading of it. Hover a point for the game, the date, hours, average and peak viewers, follows in the window, the room at the start, and at the end when it moved.
    • Room vs what happened: your sessions grouped by the room they started in, with sessions, hours, average viewers and follows per hour for each. It says “too early to say” until five sessions carry a score, because a handful of points cannot show a pattern and pretending they can is the kind of thing this site exists to stop.
    • Follows you reported in a review are listed beneath, each with its platform. The chart can only see Twitch, so a YouTube subscriber is invisible to it — a review is where that goes.
    • Each category you have streamed now shows the room over the last 14 days as a small line, and the hour it is usually most open once a week of readings exists. Built from the site’s own score rather than from the readings behind it, and starting 9 September — nothing before that is shown.
    • Nothing is backfilled. Sessions from before 9 September have no recorded score and show as grey, because there is no honest number to put there.

  2. The room score now counts the audience you can actually broadcast to

    The score used to count every viewer in a category whatever language they were watching in, and removed only the single biggest stream. On 8 September that gave Casino Simulator 2024 a 100 — 398 viewers, three channels, two Russian-language streams holding 98.5% of the room and not one English viewer — and nine of the twenty-one “wide open” categories that afternoon had no English audience at all.

    • Only viewers watching English-language streams count, and only English streams count as competition for that audience. Where you would land in the directory still counts every stream, whatever its language.
    • Everyone watching the two biggest English streams is removed before anything is shared out, so a category held by one star or by a pair of them has almost nothing left to score. The separate penalty for a dominated category is gone — removing two streams does that job.
    • A category whose whole audience is in another language scores 0, however big it is.
    • Category cards now show “no English audience” as a warning. It used to appear in green as “none in English”, as though that were good news.
    • The three homepage picks are now Most viewers each, Fewest competitors and Biggest unclaimed audience, every one measured on the English audience. The old “An audience nobody is serving” pick, which selected exactly the Casino Simulator shape, is gone.
    • Aggregator and badge-app accounts are no longer counted as streamers or viewers.
    • Every score still explains itself in a sentence, now with the English figures: how many English viewers are not watching the two biggest English streams, and roughly how many that is each.
    • The opportunity tier — Hidden Gem and the rest — is unchanged. It ranks a category against every other category regardless of language, so a room can be a gem for somebody and closed to you; the card now says both.
    • The score measures language and concentration. It does not judge what is being streamed, so a category whose English streams are not really the game will still score on its numbers.

  3. Reviews now cover any platform, and everyone reports their own numbers

    The verified tier is gone. A review used to be marked verified when this site had independently seen you live in that category — but this site can only see Twitch, so anybody who streamed on YouTube or Kick could never earn it however honest their review, and verified reviews sorted first and were the only ones counted in the summary.

    • Say which platform you streamed on: Twitch, YouTube, Kick or anywhere else.
    • You enter your own hours, follows gained and average viewers. Nothing is filled in from our observations, so nothing depends on whether we happened to be watching.
    • The summary line counts every review rather than only the ones we witnessed, and reviews are ordered newest first rather than witnessed first.
    • The list of other people who streamed a category now covers the last 24 hours only, so it answers "who is playing this today" rather than "who ever played this".
    • Reviews themselves are unchanged: five taps, no writing, one per game, editable.

  4. Your Steam library, ranked by how much room each game has

    Every other suggestion on this site asks you to go and get a game first. This one asks nothing: connect Steam and we go through what you already own and rank it by how reachable each category is on Twitch right now.

    • Sign in through Steam to link your account — Steam names the account itself, so there is nothing to look up and no password to hand over.
    • A My games page listing your whole library, in a list or as cards, with the score and the live competition beside each title.
    • Games you already own now appear on your dashboard, ranked, so the most actionable suggestion sits above everything else.
    • Games with no live Twitch category still appear, marked as such, so a game you are thinking of is never silently missing.

  5. A release calendar

    Knowing a game is coming is not the same as knowing when. Upcoming releases now lay out on a real calendar you can plan a schedule around.

    • Four months of release dates as month grids, so you can plan a schedule around them rather than reading a list.
    • Games whose date is really just a year sit in a separate tray instead of piling onto 31 December and inventing a launch day none of them has.
    • Every upcoming game gets its own page, keyed to the game rather than a Twitch category, because most unreleased games do not have one yet.

  6. A score that measures the room you can actually reach

    The old headline was average viewers per streamer. It is a mean, so a single enormous stream made a dead category look wide open. The new score removes the biggest stream first and asks what is genuinely left for somebody arriving today.

    • A 0–100 score on every category: 70 and up is wide open, 40–69 worth a shot, under 15 closed off.
    • It strips out everyone watching the single biggest stream, splits what remains across the other live channels, and penalises categories one person dominates.
    • Every score explains itself in a sentence using that category’s own numbers — how many viewers are not locked onto the biggest stream, and roughly where you would open.
    • When one stream holds nearly all the viewers, the page says so outright rather than scoring the category as though that audience were available.
    • Viewers per streamer did not disappear — it still sits beside the new score, so you can see exactly where the two disagree.
    • Sort the whole catalogue by it.
    • The arithmetic changed on 8 September — it now counts only the English-speaking audience and removes the two biggest English streams; see the entry above.

  7. Reviews from people who actually streamed it

    Star ratings are easy to fake and hard to trust. Because the collector already sees who is live and in what, a review can carry proof that the person genuinely streamed the game.

    • Rate a game in five taps — no writing, so there is nothing to moderate and no wall of text to read.
    • Reviews were marked verified when we had independently seen you live in that category, and self-reported when we had not. That distinction was dropped on 7 September; see the entry above.
    • Each review carries what the stream actually earned: hours, followers gained and average viewers, measured where we caught it and marked as reported where you told us.
    • Category cards show how many reviewers would stream it again once enough people have answered.
    • Game pages list other streamers we have seen live in that category.

  8. Game pages worth opening

    A page that only repeats the number from the card is not worth the click. Every game page now answers the questions somebody actually has before committing a stream to it.

    • Player and critic ratings side by side, plus quoted Steam reviews, so you can tell a game people love from one critics liked.
    • Trailers and screenshots where they exist, and buy links for every store that carries it.
    • A streaming facts panel: how long it takes to finish, how many people are playing on Steam right now, what genre it really is.
    • Section headings written as the question people ask — “Should I stream this?”, “Is it too saturated?” — with a direct answer in a sentence underneath, backed by the charts below it.
    • Related games, so a category that is too crowded leads somewhere rather than dead-ending.

  9. Who you would actually be competing with

    A category with forty streamers is a different proposition if thirty of them are broadcasting in a language your audience does not speak.

    • A language split on category pages, so an English-speaking streamer can see how much of the competition is actually in English.
    • Counted from the live stream list on every reading, not estimated.
  10. Sign in with Twitch, and keep a list

    Somewhere to keep the categories you are considering, and the account that makes reviews and Steam ranking possible.

    • Sign in with Twitch — no password, no email signup.
    • Save any category to My list and come back to it.
    • A dashboard showing what you streamed, what it earned you, and how much room those categories have now.
    • Delete your account and everything attached to it from the profile page, without emailing anyone.
    Start a list
  11. Every category, every fifteen minutes

    The collector used to sample the top few thousand categories globally. It now censuses every category individually, which is the change that made everything above possible.

    • Small categories are counted properly instead of being cut off by a global ranking — the exact categories a small streamer should care about.
    • Real placement: where you would actually open in a category, rather than an estimate derived from a sample.
    • Rising, falling or steady, once a category has enough history to say so — about two days.
  12. Browse and search everything

    The full catalogue, searchable, sortable, and honest about which games it can judge.

    • Around 19,000 Twitch categories, browsable and searchable, with accents handled so “Pokémon” and “Pokemon” find the same thing.
    • Sort seven ways — room, discoverability, whether an audience stays, Steam player sentiment, viewers per streamer and more.
    • A quadrant view plotting how enjoyable a game is against whether it holds an audience, because a badly reviewed game people watch anyway is a genuinely good stream.
    • Non-game categories like Just Chatting are hidden by default and can be switched back on.
    • Missing game? Add it and we will go and crawl it.
    Browse the catalogue
  13. Upcoming launches

    The least crowded moment in a category’s life is usually the week it comes out. That is only useful if you know it is coming.

    • A list of upcoming releases ranked by how anticipated they are.
    • Release dates, genres, platforms and store links for each.
    • Every upcoming game gets its own page before it has a Twitch category at all.
    See what is coming
  14. StreamArbitrage opens

    The first version: find Twitch categories with real viewers and few streamers, instead of guessing.

    • Live viewer and streamer counts for every category, refreshed continuously.
    • Game cards with genres, ratings and Steam player counts.
    • Filters for saturation and for games you cannot play.
    • Detail pages for every category.

What is not on this list

Features only — no bug fixes, and nothing that is not finished. A few things are built but deliberately left off until you can actually use them, because a list of things you cannot find is not a changelog. Where a feature needs more data before it says anything useful, the entry says so rather than overselling it.
