Chrono¶

Drop-in custom physics replication solution for Roblox!¶

Chrono provides full control over replication and physics while remaining compatible with Roblox’s networking model. It is designed to be drop-in for existing games, with a wide range of configurations allowing for custom characters and more.

Quickstart¶

Copy this into your client and server starter scripts to enable Chrono immediately.

-- Shared (both client & server)
local chrono = require(ReplicatedStorage.Packages.chrono)
chrono.Start()

For configurations, see Getting Started: Configurations.

Why Chrono?¶

Fixes Roblox replication limitations: dynamic tick rates and distance-based replication.
Smaller interpolation delay: configurable buffer control for smoother client rendering.
Snapshot history & lag compensation: snapshots API and built in lagcomp api.
Flexible model replication modes: NATIVE, NATIVE_WITH_LOCK, and CUSTOM for bandwidth/perf tradeoffs.

Showcase¶
