Drop-in server infrastructure that handles the impossible — seamless world transitions, persistent terrain deformation, and orbital mechanics — so you can focus on what makes your world unique.
Everything you need to build worlds without boundaries.
Caelestris isn't just infrastructure — it's a foundation you compose. Build a fully custom game by assembling binary plugins and scripted mods, sourced from the free community workshop and the curated paid marketplace. Stand on the community's shoulders, or ship your own.
Stable, versioned APIs mean your extensions keep working. Build native binary plugins for raw performance or scripted mods for rapid iteration — both backed by a long-term support commitment, so what you build today doesn't break tomorrow.
Monitor and manage your entire cluster from a sleek web-based interface. Real-time server heatmaps, live console output, player migrations, and granular logging controls — all at your fingertips.
Sparse voxel encoding lets players reshape the world — mine caverns, raise mountains, carve rivers — with changes that persist and sync across every explorer in real-time.
Seamless server handoffs let players walk, sail, or fly across server boundaries without loading screens. One continuous world, not a patchwork of zones.
Multiple specialized thread pools isolate workloads — terrain generation never blocks combat, physics never starves networking. Your world stays responsive under any load.
Zero-fallback architecture means no silent degradation. Every subsystem validates dependencies at startup — explicit failures with actionable diagnostics, not mysterious lag.
Spin up new server nodes on demand. Dynamic load balancing distributes players across your cluster while the grid topology expands seamlessly — from launch day crowds to viral moments.
