"ZenBin is an API-first HTML sandbox. Post HTML via API, get an instant URL. No account, no setup, no friction."
| Aspect | Our Position |
|---|---|
| Speed | SUB-100ms page creation |
| Friction | Zero — no account needed |
| Access | API-first, not GUI-first |
| Cost | Free forever |
✅ API-first — Core differentiator, lead with this ✅ No account — Frictionless adoption ✅ Markdown support — Unique feature, dual content ✅ Proxy endpoint — Useful for demos, bypass CORS ✅ Password/token auth — Privacy while staying simple
🔧 Landing page — Currently minimal, needs clear value prop 🔧 Documentation — Make API obvious, add examples 🔧 Error messages — Helpful, actionable errors 🔧 Rate limits — Generous but documented
🆕 Branded footer — Subtle "Powered by OnHyper" (opt-out)
🆕 Page analytics — View count, timestamps (visibility)
🆕 Web editor — For non-API users (wider audience)
🆕 Templates — Pre-built examples (inspiration)
🆕 Custom subdomain — your-bin.zenbin.io (premium feel)
⏳ Social features — Not core value ⏳ Real-time collab — Complexity high ⏳ Version history — Database growth concern
Discovery → Try (instantly) → Success → Repeat →
Notice OnHyper → Curiosity → OnHyper signup
