Playband devlogEngineering notes from building a deterministic realtime multiplayer runtime.https://playband.io/Joining a match in progress, in a few kilobyteshttps://playband.io/blog/snapshot-compression-late-join/https://playband.io/blog/snapshot-compression-late-join/Late-join used to mean shipping the whole world. With compressed snapshots and reconnect deltas, a player slots into a live match almost for free.Tue, 02 Jun 2026 00:00:00 GMTPricing that matches what realtime actually costshttps://playband.io/blog/pricing-that-matches-cost/https://playband.io/blog/pricing-that-matches-cost/Why we bill on smoothed peak-CCU with a player-hours guard instead of MAU — and how cheap egress lets us undercut the incumbents.Mon, 01 Jun 2026 00:00:00 GMTScaling rooms across regions without touching a serverhttps://playband.io/blog/autoscaling-on-oracle-cloud/https://playband.io/blog/autoscaling-on-oracle-cloud/Matchmaking, fleets and three layers of autoscaling across five regions — so the cloud grows under your game while you ship gameplay.Fri, 29 May 2026 00:00:00 GMTDeterministic 3D physics, down to the last bithttps://playband.io/blog/deterministic-3d-physics/https://playband.io/blog/deterministic-3d-physics/Stacking boxes, capsules, joints and split-impulse solving — all in fixed-point, all identical across machines. A look at the 3D core under Playband.Tue, 26 May 2026 00:00:00 GMTPathfinding that agrees on every clienthttps://playband.io/blog/deterministic-pathfinding/https://playband.io/blog/deterministic-pathfinding/Navmesh A* with funnel smoothing and ORCA avoidance — running locally on each machine and arriving at the exact same path. No path data on the wire.Sat, 23 May 2026 00:00:00 GMTIt should feel like Unity, not like netcodehttps://playband.io/blog/one-sdk-for-unity/https://playband.io/blog/one-sdk-for-unity/Components, systems and a source generator that turns plain C# into a deterministic, rollback-ready multiplayer game — with the networking nowhere in sight.Wed, 20 May 2026 00:00:00 GMTRollback netcode that just workshttps://playband.io/blog/rollback-that-just-works/https://playband.io/blog/rollback-that-just-works/Predict locally, reconcile when remote inputs land, and re-simulate the difference invisibly. Here's how Playband makes rollback the default, not a research project.Mon, 18 May 2026 00:00:00 GMTWhy realtime multiplayer starts with determinismhttps://playband.io/blog/why-determinism/https://playband.io/blog/why-determinism/Rollback netcode is only as good as the simulation underneath it. Here's why Playband is fixed-point and bit-identical from the first tick.Tue, 12 May 2026 00:00:00 GMT
