Hey PH! I built Mischief to bring back the joy of desktop companions — but as an open platform. It ships with 19 companions (cats, ghosts, robots, capybaras…), every one of which can hide, peek, spin, pounce, sneak, and dance on your desktop. You can import any image as a companion or author your own pack in ~10 minutes. It's MIT, no accounts, no telemetry, fully offline, and available on Windows, macOS, and Linux. Happy to answer any questions!
Hey Product Hunt! 👋 I built Mischief to bring back the joy of desktop companions — but as an open platform.
It ships with 19 companions (cats, ghosts, robots, capybaras, phoenixes…), and every single one can hide, peek, spin, pounce, sneak, and dance right on your desktop. It reacts to your work — sleeps when you're away, perks up when you return, and cheers you on during deep-focus sessions.
What makes it different:
- 🐾 It's a platform, not a single pet — you can import any image as a companion, or author your own in ~10 minutes with JSON (no code needed)
- 🔒 Privacy-first & offline — no accounts, no telemetry, zero network calls by default
- 💻 Cross-platform — Windows, macOS, and Linux with signed releases
- 🧑💻 Built like real software — strict manifest validation, a sandboxed plugin SDK, a pure tested domain layer, 159 tests, and CI with secret scanning
- 📖 MIT licensed & open source — contributions welcome
I'd love your feedback on the pack format, the companion designs, and what creatures you'd want to see next. If you try it, drop a screenshot in our Show and tell — and happy petting! 🐾

Who hunted Mischief?
Mischief was hunted by Moiz Zoaib Ali. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
