Koder
What Koder is
Koder is a free code editor for iPhone and iPad. It provides syntax highlighting for more than 80 programming languages, plus autocomplete, find and replace, a functions list, external keyboard support, and local autosave. A preview browser displays coded websites, while a built-in SSH client supports remote development. Connections include Dropbox, FTP/SFTP, and WebDAV, with transfers between local and remote files. File management covers copying, moving, extracting, sharing, uploading, downloading, exporting, deleting, and renaming. Multitasking and drag-and-drop collaboration work with Working Copy, Dropbox, and Files. Users can add custom keyboard keys for code snippets and switch between dark and light modes. Local files can be reached from a Mac or computer through a web browser, or from Finder on Mac. Two listed plans, Free and Koder Code Editor, each cost nothing.
