I Built a #1 App Store Developer Tool in Pure SwiftUI — Here's What I Learned

I got tired of jumping between browser tabs every time I needed to format JSON, convert a color, test regex, or hash a string. So I spent 6 months building a fix. The result: Devly — a native macOS menu bar app with 50+ developer utilities. It just hit #1 in Developer Tools on the App Store. The Problem I Was Solving Every developer knows the pain. You need to: Quickly format some JSON Convert a hex color to RGB Test a regex pattern Decode a Base64 string Generate a UUID So you open a browser tab. Then another. Then another. Context switching kills your flow. What I Built Devly sits in your macOS menu bar. One click gets you instant access to 50+ tools: Encoding: Base64, URL, HTML, JWT, Unicode, Morse, ROT13 Hashing: MD5, SHA-256/384/512, HMAC, bcrypt, UUID generator Formats: JSON, YAML, XML, CSV, SQL, TOML Web Dev: Color converter, CSS/JS minifier, Markdown preview Text: Regex tester, diff tool, case converter, timestamp converter Th
