About

Atom is a hackable text editor for the 21st century, built on Electron, and based on everything we love about our favorite editors. We designed it to be deeply customizable, but still approachable using the default configuration. A text editor is at the core of a developer’s toolbox, but it doesn't usually work alone. Work with Git and GitHub directly from Atom with the GitHub package. Create new branches, stage and commit, push and pull, resolve merge conflicts, view pull requests and more—all from within your editor. The GitHub package is already bundled with Atom, so you're ready to go! Atom works across operating systems. Use it on OS X, Windows, or Linux. Search for and install new packages or create your own right from Atom. Atom helps you write code faster with a smart and flexible autocomplete. Easily browse and open a single file, a whole project, or multiple projects in one window.

About

Koi Editor is a professional text editor for Mac, built around three principles: fast, local, and scriptable. Koi is designed for responsive editing from ordinary source files to very large documents. It includes multi-cursor editing, synchronized views, project-wide search, context-aware autocomplete, syntax highlighting for 30+ languages, code folding, file outlines, configurable themes and keybindings, and extensive editing commands. Koi requires no account, includes no telemetry, and can operate entirely offline. Configuration and keybindings are plain text, and custom editor commands can be written in Python. Optional AI features connect directly to local models through Ollama for code completion and inline assistance. Built specifically for Apple Silicon Macs, Koi combines a high-performance editing core with native macOS integration.
