HTTP 402 micropayments for pay-per-icon SVG generation—genuinely novel payment mechanism.
CSS property icons for design tools, but icon sets for dev UIs already exist.
Treats icons like a living design system — generate a full set, then request new icons that match the original style and stroke weight. Offers stroke-thickness controls, SVG/PNG/font exports and commercial licensing, which actually targets a recurring pain point for teams who hate mixing packs; the open question is how well the model handles complex or niche iconography and what the production limits are.
Free, no-signup icon exporter with proper iOS/Android asset structure beats makeappicon's paywalls.
It wires a simple but satisfying UX — drag-and-drop a .app into a 'Drop Your App Here' window and the app creates a rule folder, edits rule.conf, and applies default.icns/png automatically. The implementation leans on a filesystem watcher and menu‑bar controls (no Dock icon), which makes repeated theming and bulk updates trivial; it's not groundbreaking, but it's exactly the sort of small automation macOS tinkerers will love. The only real friction is that you build and run it in Xcode rather than a packaged release.
Genetic algorithms for icon sorting is a clever over-engineering win.
