Terminalizer is a command-line tool that lets you record your terminal session and turn it into an animated GIF image or a shareable web player link. If you have ever wanted to show someone a sequence of commands and their output, for documentation, tutorials, or demos, this tool captures exactly that and produces a visual recording you can embed anywhere. The workflow is straightforward: you run a record command to start capturing, do whatever you want in the terminal, then stop recording. The result is saved as a configuration file you can edit to trim frames, adjust timing, and change visual settings. Then you run a render command to produce the animated GIF, or a share command to upload it and get a link to an online player. Customization is extensive. You can change the font, colors, cursor style, line height, and add a watermark. You can also choose from several frame border styles, window-style borders, floating panels, or no border at all, to make the recording look like a polished screenshot. The delay between frames is configurable, including a cap on how long idle pauses are allowed to last. The tool is built in JavaScript and runs on Node.js, making it cross-platform. It is primarily aimed at developers and technical writers who want to create clean, professional terminal demos without screencasting software.
