How it works
Describe a game. Watch it play inside a post.
feedcade writes the game from your description, runs it in a sealed sandbox and hands back a link that X turns into a playable card in the timeline. Everyone who opens it shares one room. If it catches on, back it with a pump.fun coin and collect creator fees as it trades.

The steps
01 · Describe
Pitch the game, skip the code.
Write it the way you'd explain it to a friend. The builder already knows the 480×480 frame, which controls work on a phone, and how to plug a game into its shared room.

02 · Build
The game writes itself while you watch.
HTML streams in line by line and the preview boots beside it. Ask for changes in plain words. Every version is kept, and when something breaks at runtime you get a one-tap Fix it.

03 · Sandbox
Hosted in a box it can't climb out of.
Each game is served under a sandbox CSP on an opaque origin. It can draw, make noise and talk to its own room. It can't read cookies, reach your account or poke at this site.

The game can draw, play and talk to its own room. Nothing else.
04 · Post
Share the link. The post turns into the game.
Your /s/ link carries an X player card. X shows a preview still first, then loads the player right in the timeline, so nobody leaves the feed to have a go.

05 · Play together
Every reply is one more player in the same room.
window.feedcade gives each game shared state and live presence. Scores, votes and drawings reach everyone with the post open in about 0.9 s, and the “here now” count covers the last 20 seconds.
your paint shows at once · everyone else's lands within a sync
06 · Back it
Give it a coin, and earn while it trades.
One approval in Phantom or Solflare creates a real pump.fun coin whose website is your game. Creator fees go to you or split across up to 10 wallets, locked on chain. Add a dev buy to the same transaction if you like.

Under the hood
A link, a card
and a sealed player.
X will run a web page inside a post when the linked page declares a player card. Your share page declares it, X frames the player at 480×480, and a preview still fills the square until the game is ready.
/s/<id>
the link you share
/p/<id>
the player X frames
/api/card/<id>
the still X shows first
- 1You post the /s/ link.
- 2X fetches it and finds the player card.
- 3Readers see the still, then the live game in the post.

})Coins & fees
Trades pay the people you picked at launch.
Every trade of a pump.fun coin carries a creator fee. Decide once, when the coin is created, whether it all comes to you or gets shared across up to 10 wallets. Play with the numbers below to get a feel for it.
pump.fun decides the creator rate, and it moves as market cap grows. Treat this as a dial for your own guess.
Who gets paid
Up to 10 wallets. The split is written to pump.fun's fee sharing at launch and can't be edited afterwards, by you or by us.
Creator fees per day
$73.50
≈ $2,205 over 30 days at this pace
- You60%$44.10
- Co-builder40%$29.40
Back-of-the-envelope only. Actual fees depend on real trading and pump.fun's rates.
Safety
Safe by design, not by promise.
Sealed sandbox
Games load on an opaque origin with no same-origin rights. Your cookies, your session and this site are all out of reach.
No sign-up
Build and play without an account. A private edit key in your browser is what proves a game is yours.
Your wallet signs
Coins are created from your own Phantom or Solflare. feedcade never holds a private key or touches your fees.
Nothing gets lost
Each edit becomes a saved version. Roll back to any earlier build in a tap if a change goes sideways.
Split set in stone
The fee split lives in pump.fun's own fee-sharing program. Once locked, nobody can redirect it. Not you, not us.
First in line
An optional dev buy rides in the very transaction that creates the coin, so it lands the moment the coin exists.
ready when you are
Someone's next post is a game. Make it yours.
Describe it in a sentence, drop the link, and let the replies fight over the high score.
