Vast Logic — Independent Creative Studio

Vast Logic is an independent creative studio. After years of building products at leading tech companies, we set out to make things of our own: simple but powerful, and cared for down to the last detail.
Most products settle for two. We hold out for all three.
A pleasure to look at and to hold. Type, space, and motion, done with enough care that nothing needs forgiving.
It does the one thing you opened it for, quickly, with as few steps as we can honestly manage. Practical over clever.
Solid underneath, kept in good repair. Still worth opening years from now, not a year of polish and then silence.
We build native apps for Apple platforms, with attention to performance, platform conventions, and detail.
Fast and lightweight things for the browser: practical, focused, and out of the way.
We create utilities and automation that remove friction from everyday development workflows.
An IPTV & M3U player for Apple TV
Plays the M3U playlists and live streams you add, natively on Apple TV: 4K HDR, carrier IPTV with multicast and RTSP, and an XMLTV program guide, with sound and picture in sync for hours. No accounts, no ads.
A native Markdown reader for Mac
Built for reviewing the docs your AI agents write. Plans and designs open as finished documents, with an outline on the left and room for tables, code, and diagrams. Switch to the source to make an edit, and when the agent rewrites the file, the window keeps up.
Lock your Mac, keep the screen on
A menu bar app for macOS. Step away and it covers every display with a tint you can barely see. Your desktop stays lit and keeps moving, so it looks like you'll be right back. Touch a key or the mouse, and it asks for your PIN.
A fast, native V2EX client for iPhone & iPad
Built natively with UIKit for full-frame-rate browsing and carefully tuned reading — plus an AI companion that summarizes whole threads and turns reply sections into ranked tallies, running on your own key and your choice of provider.
Vast Logic was founded by engineers who spent many years at leading tech companies, shipping products used by millions of people.
We started Vast Logic to build differently: a focused studio with high standards, making things good enough that we reach for them ourselves, every day. Everything we release gets full attention, from architecture to the last pixel.
We believe good design is quiet: it respects your time, your privacy, and your device.
