What is Steam Next Fest, and who can enter?

On 19 October 2026 at 10 a.m. Pacific, thousands of unreleased games put up a demo at the same moment, and Steam turns its front page over to them for seven days. That is Steam Next Fest. Valve's own description is short: a week-long event "focused on promoting upcoming games with playable demos", run in February, June and October.

The obvious reading is that it is a sale with demos. It is closer to a launch you get to rehearse. Players browse by genre, download what looks good, and wishlist what they enjoyed, and Steam watches what they play. For the first few days the lists are shuffled; after that, a signed-in player sees carousels personalised from what they did during the event. When it ends, Valve publishes a wrap-up page of the most-played demos of that edition and emails the developers who made it.

Valve sells no advertising for it. Its FAQ answers the question in one word: no.

Valve's eligibility list has six conditions, and a game needs all of them:

1. It has never taken part in a Next Fest. A game may enter only one.
2. It belongs to a Steamworks account in good standing.
3. Its store page is published and public.
4. It has a public, playable demo by the time the fest begins.
5. It will not release before that edition ends. A release date set before the fest starts blocks registration.
6. It is not a prologue, preview or short version of a game already out on Steam.

Free games and Early Access games can enter, as long as they are unreleased. Valve sets no minimum for demo length, no exclusivity and no rule about how far away your launch is.

No. Valve's rule is one Next Fest per game, ever, and that is the most expensive mistake to make here. Entering with a demo that is not ready spends a slot you cannot get back. If your demo would not survive a stranger playing it for twenty minutes, enter the next edition instead: there are three a year.

Valve publishes each edition's dates on its own page. Counted back from the day the fest starts:

• Registration closes about six to seven weeks before. For February 2027 it closes on 10 January 2027 at 11:59 p.m. Pacific.
• Five weeks before, the Developer Preview opens. If you want the demo live for the Press Preview, its build and store page should be in review by then (25 January for February 2027).
• Three weeks before, everything has to be submitted for review, or your place in that edition is at risk (8 February for February 2027).
• Eleven days before, the Press Preview begins. Press see every registered game, and a demo you release now is playable by everyone on Steam, not only press.
• Four days before, Valve's Next Fest trailer goes out.
• Then the week itself, opening and closing at 10 a.m. Pacific.

You register from the base game, not the demo, on its App Landing Page in Steamworks, and pick one or two primary categories. A green tick on that page means you are in.

The demo is its own app in Steamworks, of the demo type, attached to the base game, with its own store assets and its own build review. Valve's review checks that the demo runs and does what the page promises; in its own words it is "not a full QA process". You can update the demo after it is approved, and updates are not reviewed again.

Release it any time after approval, but before the fest starts, or it does not appear. Valve recommends at least 30 minutes before. If you use a separate store page for the demo, republish the base game so the two are linked.

Releasing early has a benefit beyond the fest: Steam lets you email your wishlisters about a demo within 14 days of its launch.

There are two schools. One releases the demo the day the fest opens, so every player who finds it during the week finds it new. The other releases it weeks or months before, gathers reviews and fixes, and arrives at the fest with a demo that has already been played. Valve's rules allow both: the only hard line is that the demo is live before the fest starts.

Whichever you pick, the demo should be the best fifteen to thirty minutes of the game, not the first fifteen to thirty.

Most of the work is the store page, because that is what a player decides on before they ever download the demo. The capsule has to read at small sizes, the first screenshots have to show play, and the trailer has to show the game in its first seconds. The Steam store page kit lists every asset size and rule.

Then the demo itself: it has to start fast, end on a reason to wishlist, and survive a player you will never meet. Put a wishlist button on its last screen. Play it on a machine that is not yours. Read every crash report from the week before the fest, not after.

Last, decide whether you will stream. Valve gives streams of participating games their own section and asks you to test your stream first and broadcast to your store page. Our Next Fest livestream guide covers the setup.

Next Fest is Valve's. Around it run independent digital showcases, curated streams that take submissions through their own forms with their own deadlines, often months ahead. A showcase picks a handful of games and puts them in front of an audience that came to watch; Next Fest takes every eligible game and lets players sort it out. Doing both is common, and a showcase does not count against your one Next Fest.

Flockbay is a free AI game builder on the official Godot engine, and it prepares the publishing side too. Its Steam page drafts the store copy, tags and content survey, cuts the capsule and library art from a real frame of your game, and exports the whole page as a .zip you upload in Steamworks yourself; preparing it by hand and the .zip stay free. Video studio cuts trailers and devlogs from your real gameplay, and playtest links get your demo in front of testers before Valve's reviewers. The publishing tools are free in beta until 1 December 2026. Flockbay never uploads anything to Steam: the Steamworks account, the registration and the build review are yours.
