About

A lightweight, multi-language programming text editor and IDE for macOS. CodeRunner was designed to support all of the most widely used programming languages and run them instantly. The app is configured to run code in 25 languages out-of-the-box, and additional languages can be configured to run by simply entering their terminal command. With over 200 syntax modes, lots of advanced editing features and thoughtful details, CodeRunner will quickly become your go-to editor for any and all kinds of text files. CodeRunner's code completion is the best you'll find in any IDE. Intelligent matching of typed text enables completions beyond single words. Quickly find the right completion among thousands with the extra-fuzzy search algorithm, helpful documentation snippets, and smart ranking of results. Don't clutter your code with print-statements for debugging. Instead, use CodeRunner's built-in debugging features to set breakpoints and step through your code.

About

Koi Editor is a fast, minimal, scriptable code and text editor for macOS, designed around low typing latency, large-file performance, and local workflows. Koi provides multi-cursor editing, multiple synchronized views of the same document, project-wide search, file and buffer navigation, syntax highlighting, code completion, configurable themes and keybindings, and extensive text-editing commands. The editor is designed to remain responsive with large source files, logs, and structured text, and has been tested with files containing tens of millions of lines while retaining syntax highlighting and core editing functionality. Optional AI features support local models through Ollama for code completion and inline assistance. Koi can operate entirely offline, requires no account, and includes no telemetry. Koi is built specifically for Apple Silicon Macs and combines a custom editing engine with native macOS integration.
