Fed on Real Git Commits
DevPet uses native Darwin file-system dispatch events to detect commits in your monitored repositories. Commits restore hunger, grant XP, and trigger joyful dances.
Apple Silicon Mach Kernel Telemetry
Integrated with Darwin's host_processor_info. When you compile Rust/Swift, build Docker images, or train LLMs, DevPet breaks a sweat in Overclock Crunch Mode.
Menu Bar & Floating Screen Buddy
Choose whether DevPet lives as a sleek compact menu bar popover or a transparent, click-through floating companion lounging on your screen above the dock.
macOS Menu Bar Popover
Glance at current vitals, digested commits, and hardware stats with a single click in your top system bar.
Floating Desktop HUD
Zero-distraction companion that animates alongside your IDE with customizable opacity and click-through mode.
Control Everything from Your Shell
DevPet responds to custom macOS URL schemes. Add these single-line aliases to your .zshrc or Git hooks for seamless command line automation.
alias coffee="open 'devpet://feed?item=espresso'"
alias pizza="open 'devpet://feed?item=pizza'"
function gc() { git commit "$@" && open "devpet://commit?msg=$(git log -1 --pretty=format:%s | head -c 40)"; }

Everything You Need to Know
Everything you need to know about setting up and using DevPet.
DevPet uses macOS native DispatchSourceFileSystemObject kernel notifications to monitor the .git/logs/HEAD or refs/heads directory. It doesn't poll repeatedly in a sleep loop, consuming zero noticeable CPU cycles.
Never. DevPet only inspects commit timestamps and commit messages to trigger pet feeding. It contains a Privacy Manifest (PrivacyInfo.xcprivacy) confirming zero data collection.
Yes! DevPet integrates with VS Code, Xcode, Cursor, Zed, Ghostty, iTerm2, Kitty, and standard Terminal via custom URL schemes (`devpet://feed` and `devpet://commit`).
DevPet enters sleep mode. It won't die, but its hunger and happiness drop. Feeding it snacks from the Geek Pantry or shipping a hotfix restores its spirits instantly!
