vise — 为 macOS 打造的原生工具箱: 31 native macOS dev tools in one offline app

I built vise because my Mac had turned into a graveyard of single-purpose tabs and utilities: one web app for Base64, another for JWT decoding, a random site for cron expressions. Pasting work data into someone else's website is a bad habit, and none of it works on a plane. So vise is the opposite of that: 31 developer tools in one native app, fully offline. No network permission is even used — every conversion, hash, and diff happens on device. Three constraints drove the whole build: 1. Modularity — every tool is its own Swift package with zero dependencies on the others. Deleting a tool is deleting one line in the registry. The app shell literally doesn't know the concrete type of any tool. 2. Design — SwiftUI following macOS 26 (Liquid Glass) HIG, not an iOS port. Glass only on chrome, never on content. Ships back to macOS 14 with graceful fallbacks. 3. Performance — the main thread only does UI. Heavy work (image processing, hashing large files, diffing, syntax highlighting) is pushed off-main with Swift 6 concurrency. Hashing streams files in 1 MB chunks; the code editor highlights incrementally and only the visible range. The part I enjoyed most: the same tool declaration powers three surfaces. One `Tool` type feeds the GUI, a bundled `vise` CLI (`vise json format '{"a":1}'`), and auto-generated AI skill files, so an agent can use the tools without me writing a second API. Clipboard smart detection came from DevUtils — copy a JWT, hit ⌘K, and the right tool is already waiting with your text in it. Would love to hear which tools you'd want next, and whether the quick-panel workflow (global hotkey → floating single-tool window → pin to desktop) fits how you work.
