Hi Product Hunt! 👋

I’m a solo dev from Japan 🇯🇵. I built StingerCrafter because I needed transparent WebM stinger transitions for my YouTube channel — and existing tools felt too bloated.

Fun fact: I tried to have AI code this for me. It gave up on the complexity, so I built the rendering engine from scratch. 🤖💪

Why StingerCrafter?

✅ Transparent WebM stingers (with alpha) — works with OBS instantly

✅ No After Effects — 100% in-browser rendering

✅ License-compliant — ffmpeg.wasm build (GPL deps stripped)

✅ Free tier — 30fps downloads are free forever

👇 Which animation pack should I ship next?

1. Glitch 👾

2. Geometric 🔺

3. Japan-inspired (Kawaii / Ninja / Samurai?) 🥷 (Since I'm from Japan!)

or tell me your idea!

Can’t wait to hear your thoughts! 🚀

UPDATE: I just shipped a new pack: "Ninja Style" 🥷✨
It’s one take on a Japan-inspired stinger transition — you can customize colors, text, and logo in the browser and export a transparent WebM for OBS.
