Show HN: Oh-my-logo – Generate colorful ASCII-gradient logos with one command

Hi HN,

I just open-sourced oh-my-logo, a tiny Node.js CLI that turns any text into a vibrant, gradient-filled ASCII logo (inspired by the banners you see in Gemini CLI and Claude Code blocks).

Demo Image: https://raw.githubusercontent.com/shinshin86/oh-my-logo/main... Demo GIF: https://raw.githubusercontent.com/shinshin86/oh-my-logo/refs...

Quick try (no install): npx oh-my-logo "HELLO HN" fire --filled

Key points - Two rendering modes: outlined ASCII or filled block characters - 13 color palettes (sunset, matrix, etc.) and custom schemes - Vertical, horizontal, and diagonal gradients - Multi-line support - Zero dependencies; runs instantly with npx - Cross-platform (macOS, Linux, Windows/PowerShell)

I’d love your feedback: - Does it render correctly in your shell/OS? - Extra features or fonts you’d find useful? - Any cool use-cases you can think of?

Thanks for checking it out!
