What’s new

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

  1. 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, rank it by how reachable each category is on Twitch right now, and tell you the best hour to go live with each.

    • 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, the live competition and the best hour 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.

  2. A release calendar, and timing for one game at a time

    Knowing a game is coming is not the same as knowing when. Upcoming releases now lay out on a real calendar, and the timing page answers for a single category instead of only the whole directory.

    • 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.
    • Search any category on the When to stream page and get its own hour-by-hour curve rather than the directory average.
    • 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.

  3. 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.
    Browse by room
  4. 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 are marked verified when we independently saw you live in that category, and self-reported when we did not.
    • 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.

  5. 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.

  6. Which day of the week, and who you would be competing with

    The best hour is only half the question. Days differ from each other as much as hours do, and the language a category is streamed in changes who you are actually up against.

    • A day-of-week chart for any individual category, showing which days have more room than that category usually has.
    • It publishes the lift rather than an absolute figure, because a Tuesday and a Saturday are only comparable against the same category’s own average.
    • A language split on category pages, so an English-speaking streamer can see how much of the competition is actually in English.
    • The chart needs about a fortnight of readings for a category before it will draw one — until then it says so rather than showing a shape it cannot support.

  7. When to stream, not just what

    Going live at the busiest hour is not the same as going live at the best hour. Viewers and streamers peak together, so the question worth asking is when the audience is largest per streamer competing for it.

    • An hour-by-hour curve for the whole directory and for any single category.
    • The biggest stream is removed from every hour before the ratio is taken — otherwise one huge broadcast makes an hour look open when one person holds the room.
    • Times are converted to your own clock in the browser, so there is no UTC arithmetic to do.
    • Bars are relative to that category’s own average, so a 1.4× hour means more room than it usually has.
    Find your hour
  8. Sign in with Twitch, and keep a list

    Somewhere to keep the categories you are considering, and the account that makes verified 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
  9. 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.
    • A daily audience-versus-competition chart on every game page.
  10. 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
  11. 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.

  12. 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.
