A new integrated development environment called Mine now supports both Coalton and Common Lisp across Windows, macOS, and Linux. The editor offers two distributions: mine-app provides a complete packaged application with no dependencies, while mine-core is a command-line variant requiring a Unicode-capable terminal with Kitty keyboard protocol support.

The IDE includes an integrated REPL that allows developers to beam code from functions to entire projects for immediate interaction. An interactive debugger pops up on errors with correction options and stack traces. Inline diagnostics flag errors, warnings, and optimization hints directly in the editor, helping developers catch issues early.

For Coalton development, type hints display the full data type of functions under the cursor, and auto-complete assists with function names. Built-in structural editing lessons teach the feature in approximately five minutes. All code compiles to native binary for the CPU, avoiding virtual machines or interpreters for maximum performance.
