Small tools,built with care.
macOS apps, browser extensions and small web tools I build. Most of them I use every day, and I ship them once they feel right. Most are free.

The ones I’ve polished longest and that people use most. Open them in the browser or download them to your Mac.
macOS App
Dropline
Why I built itEvery upload meant going back to a dashboard to copy the link, dozens of times a day.
A menu bar uploader for macOS that turns “upload, then grab the link” into a single drag. Whichever way a file comes in, what comes out is a public link in your clipboard.
- Window / Dock / Finder / clipboard / menu bar
- Uploads straight to your S3, R2 or image host
- Keys in Keychain, no account, no telemetry
macOS App
Easy Kap
Why I built itI just wanted a 10-second clip for a PR, and the tools out there were either too heavy or too slow to export.
A native macOS screen recorder: drag a region and record, trim right in the looping preview, export a GIF or video and drop it into a PR or chat.
- Region / window / full screen
- System audio + mic, pause anytime
- Open source, auto updates
Map Project
IMAX Theaters in China
Why I built itI wanted the nearest IMAX with the biggest screen, but the details were scattered and impossible to compare.
Theater listings turned into a map you can browse, so you can check locations and plan the trip before a movie.
- Map first
- Made for browsing, not searching
- Easy to take in
Creator Tool
SnapKitty
Why I built itI wanted to keep Xiaohongshu photos as they were, but they always came watermarked, one tap at a time.
A tool for saving and reusing content you come back to often. The point is fewer steps: open it and it just works.
- No sign-in
- Photos / videos / audio
- Good for everyday archiving
