Start free. Grow without migrating.
Every game starts on a free, shareable link. When yours gets traction, you upgrade in place — same link, same leaderboard, more headroom. No re-deploy, no rip-and-replace.

Will my free game break when I outgrow the free tier?
No. Upgrading attaches your existing rooms and scores to your account — the link you already shared keeps working. Growth is an upgrade, never a migration.
Is 8 players really enough?
For most games shared with friends, yes. Pro raises the per-room cap and lifts your concurrent-room limit from 25 to 150 — a popular game runs lots of small rooms at once, and that’s what usage-based pricing covers, not the player count in any one room.
Can I build a server-authoritative (sim) game on the free plan?
You can write and deploy one for free — we validate your
sim.js and tell you exactly what’s broken. Running it on our CPU is the
paid part: live sim rooms, probe_sim, and server-side verification of a
sim game all need Pro. Classic multiplayer — rooms, sync, presence, events,
leaderboards, and verification — stays unlimited on every plan, including without an
account.
