Slipstream

Online multiplayer for an indie game shouldn't require hiring a backend team. Slipstream is the sync layer that turns "I have a single-player game" into "I have a single-player game with rooms, lobbies, presence, and authoritative server state" in roughly a weekend.

You describe your shared game state as a regular TypeScript object. Slipstream snapshots it, diffs it, sends only what changed, and reconciles client predictions with server truth automatically. Rollback, interpolation, lag compensation — all handled by the runtime. You write game code, not netcode.

Pricing is per concurrent player, capped at the price of a single AWS instance. We run on edge regions in 18 cities, so the player whose game-feel matters the most — the one closest to the action — gets latency under 30ms. Slipstream is what we wish we'd had when we shipped our last three games the hard way.
