Hey everyone 👋
I'm Reon, a solo dev from Johannesburg, and this is UrgencyKit — my attempt to fix something that annoyed me for years: you can't put a real countdown timer in an email.
Every email client strips JavaScript for security, so all those slick web countdown widgets just... break in the inbox. The usual workaround is exporting a static image from Canva, which freezes the time forever and shows "2 days left" a week after your sale ended. Not great.
UrgencyKit gets around it by rendering the countdown as an image on the server, fresh on every open. No JS, no plugin — it's literally one tag, so it drops into Mailchimp, Klaviyo, Beehiiv, Gmail, Outlook, anywhere images load. You upload your own banner and the live countdown renders right onto your design, so it looks like your brand instead of a generic widget.
The fun engineering part: generating a new countdown GIF on every single email open means the rendering pipeline has to be fast and cheap at scale. Built the whole thing in C#/.NET, and getting per-frame image generation to stay snappy under load was the problem I enjoyed most.
It's brand new, so I'd genuinely love feedback from this community.
Free plan needs no credit card if you want to try it on a real campaign. I'll be here all day answering everything 🙏
