twinny, a self-hosted alternative to Cursor.
Cursor is an editor of its own, a fork of VS Code, with the AI features wired to models it hosts. twinny is an extension for the VS Code you already have, wired to a model server of your choosing. Which is right depends on whether a new editor is acceptable and whether your code may leave the machine.
