Build SCP: SL plugins with blocks.
Cobalt turns every system in the game — players, doors, SCPs, rounds, items — into blocks you snap together. No syntax to learn, no environment to set up: connect the blocks and your plugin is ready for your server.
If you can drag a block from A to B, you already know how to use Cobalt.

From idea to plugin in three steps
No code to write — just blocks to connect in the right order.
- 01
Drag the blocks
Pick from the library: game events, player actions, doors, SCPs, rounds. Every system in the game is ready to use.
- 02
Connect the logic
Snap conditions, variables and actions together like a puzzle. Cobalt checks that every piece fits while you work.
- 03
Publish to your server
Cobalt compiles your blocks into a working plugin, ready to load on your SCP:SL server.
A library that covers the whole game
Every category in the sidebar is a set of ready-made blocks, from basic logic to individual SCPs.
