They play.
You see why.

A playtest recorder for Unity. Gameplay, webcam, mic and your game's own events land on one timeline, kept in Mulno Cloud or in your own bucket. Claude can read every session.

Free for 20 sessions a month · Unity 2022.3 LTS and 6 · Windows today

Coming soon to your country: Mulno is open to studios in Thailand first. Contact us and we'll tell you when it opens where you are.

A sample game session: a young adventurer at a stone lever in a torch-lit dungeon, with the tester's webcam in the corner. 12:04.300

Your game writes the timeline.

Call one line where something happens. Markers, spans and regions land on the same clock as the picture, the webcam and the mic. Or draw regions in the scene and skip the code.

Assets/Scripts/Hangar.cs Playtest.Mark("checkpoint/reached");
Hangar.cs Playtest.Mark("checkpoint/reached");
void OnEnterHangar() {
hangar = Playtest.BeginSpan("level/hangar");
}
 
void OnLeverPulled() {
Playtest.Mark("puzzle/lever");
}

Then: open it in Studio.

Every call becomes a clip or a tick you can jump to, filter and search across sessions. Regions come from shapes and colliders you place in the scene.

What's inside.

A recorder in the game, a launcher for testers, Studio for you, and a broker we host. On a Private bucket it never touches your footage.

Mulno Cloud, or your own bucket.

Sessions upload straight from the tester's PC, to Mulno Cloud (a new project's default) or to your own R2. On a Private bucket, our servers can't read a byte unless you lend them a read key.

Claude reads every session.

mulno mcp hands sessions, events and notes to Claude Code. Ask across a whole campaign; it answers with moment links.

Testers always know.

Nothing records until the tester agrees, and REC stays on screen the whole time. They can pause, flag a moment or withdraw.

Builds that patch, not re-download.

Testers enter your code in the Mulno Launcher, accept the NDA, and play. On each new build it only fetches the chunks that changed since their last one.

Coming soon: free to try.

Every studio starts on Free: 15 GB Mulno Cloud, or your own bucket, and 20 remote sessions a month. When you need more, we agree a price with your studio.
