All comparisons

Looking for a Playroom alternative?

Multiplayer Agent is a Playroom alternative that prices the same way, by monthly active players, with no concurrency limits, and adds the parts you reach for after the prototype works: server-authoritative game rules, player accounts and saves, leaderboards and monetization.

We agree about pricing, and that is the point

Playroom got the meter right. Charging by monthly active players rather than concurrent connections is the only unit a solo developer can predict for their own game, and we price the same way for the same reason.

So the comparison is not really about cost model. It is about what happens after the first prototype works.

What you get once the prototype works

A lot of multiplayer tooling is excellent at the first hour and thin after it. The things a game needs in week two are the things we have built out:

server logicdecides collisions, scores, winnersclient 1sends inputs onlyclient 2sends inputs onlyclient 3sends inputs onlyinputs upstate down
Server-authoritative logic is the piece most prototypes skip. Inputs travel up, decisions travel down, and the client never gets to name its own score.
  • Server-authoritative logic: rules that run on the server, so scores and outcomes cannot be edited by a client. Versioned, with rollback and error logs.
  • Player identity and saves: anonymous-first, with an optional username so progress survives a lost device.
  • Leaderboards, scoped per game or across your whole studio.
  • Player-created content: publishing, browsing, voting and moderation for player-made levels or decks.
  • Monetization through Stripe, plus your own ads id so ad revenue stays entirely yours.
  • First-party analytics: sessions, retention, concurrency and client errors, per game.

Built to be driven by an agent

The whole platform is reachable from an AI coding agent, not just from a documentation site. That means you can describe the game you want in your editor and have the room defined, the logic deployed and the snippet written without switching windows.

It matters more than it sounds: the fastest path from idea to two people playing is the one where nobody reads an API reference first.

Honest limits

All room state replicates to everyone in the room, which makes hidden-information games awkward unless you keep the secret in server logic. And this is not built for competitive twitch play, no client prediction or rollback. Casual, co-op, turn-based and .io-style games are the sweet spot.

Common questions

Do you limit concurrent players?

There is a per-game ceiling on each plan as a safety rail, but it is sized so that a game hitting it is already a hit. You are not billed by concurrency and a traffic spike does not cost extra.

Can I use my own ads?

Yes. Add your ads publisher id per game and keep 100% of the ad revenue. We take a cut only on in-game purchases sold through the platform.
