Alternis is an experimental dialogue editor and open source dialogue middleware that fits on the web or in any game engine portably.

Let your writers express the logic of their dialogs with intuitive path-locking, random switches, and more—
All visually and without writing code.

Give your programmers the flexibility they need by declaring variables and functions for them to fill-in and edit.

All in a tiny native library with a C API that embeds in any platform easily, already with these integrations: for Godot, Unreal, and the web.
