Powerlevel10k is a highly customizable theme for Zsh, which is the shell (command-line interpreter) used by default on macOS and available on Linux. A shell theme controls what your command prompt looks like: the line of text that appears every time you are ready to type a new command. Powerlevel10k makes that prompt informative by showing useful context at a glance, your current directory, git branch and status, whether the last command succeeded or failed, the Python virtual environment you are in, execution time of the previous command, and dozens of other configurable indicators. Its key selling point is speed. Many feature-rich shell themes introduce noticeable lag between when you press Enter and when the next prompt appears. Powerlevel10k is engineered to eliminate that lag entirely through a combination of asynchronous computation (so slow operations like git status checks don't block the prompt from appearing), instant prompt (which shows the prompt immediately while background tasks catch up), and highly optimized shell code. It also includes a built-in interactive configuration wizard accessible by typing p10k configure, which walks you through visual style choices to set up your prompt exactly how you want it. You would use Powerlevel10k if you use Zsh as your shell and want a visually rich, fast prompt without extensive manual configuration. It is compatible with the popular Oh My Zsh plugin framework and can serve as a drop-in replacement for the earlier Powerlevel9k theme. The README prominently notes the project now has very limited support with no new features being developed and most bugs going unfixed. The tech stack is entirely Shell script for Zsh.
