What it does

Turn static email banners into live countdown images that update every time your email is opened — no JavaScript, no plugins, no platform lock-in. Upload your design, add a countdown, and paste one image tag into Mailchimp, Klaviyo, Beehiiv, Gmail, Outlook, or any email tool. Per-recipient deadlines, animated final seconds, custom expired states, and engagement analytics. API on every paid plan. Perfect for flash sales, product launches, webinars, and limited-time offers.

Create dynamic countdown timer images for email campaigns — live images that update every time the email is opened. Works with Mailchimp, Klaviyo, Outlook, Gmail and any email platform. Free plan available.

Create dynamic countdown images that update when your email is opened. Perfect for sales, launches, webinars, events, and limited-time offers. Personalize the deadline for every recipient and turn urgency into opens, clicks, and sales. Works with Mailchimp, Klaviyo, Beehiiv, ConvertKit, Gmail, Outlook, and any email platform that supports images. Our biggest sale of the year. Time is running out — here's where things stand right now. Most email clients block JavaScript, which means normal web countdown timers do not work inside emails. UrgencyKit solves this with dynamic images. Most email platforms strip scripts for security, so normal countdown widgets break completely. A Canva export…from urgencykit.com

    I built Countdown Builder as a lightweight way to add urgency to email campaigns. Most ESPs don’t provide native countdown timers, and existing solutions are either clunky, expensive, or not very customizable. Countdown Builder lets you: Design a countdown timer (fonts, colors, styles) Preview in real-time Generate a snippet to embed directly into your email Use cases: flash sales, product launches, webinars, or any campaign where showing “time left” works better than just saying it. I’d love feedback from this community on: Edge cases I might have overlooked (email client compatibility,…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  • Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
