UpsellBoost

What it does

UpsellBoost helps Shopify merchants increase revenue while optimizing inventory. Promote slow-moving products through smart cross-sells, push low-stock items before they sell out, and automatically recommend alternative products when items are out of stock. Launch high-converting upsells and cross-sells in minutes—without coding.

Boost AOV with smart cart upsells and post-purchase popups. Zero commission, no coding needed. Free plan available.

UpsellBoost grows your AOV automatically. Show the perfect upsell to every customer in the cart drawer and immediately after checkout — no coding needed. Set smart rules based on cart contents, order size, payment method, or stock levels. Each upsell appears as a beautiful swipeable carousel with urgency timers and one-tap add to cart. Track every accepted upsell, revenue added, and acceptance rate in your analytics dashboard. Works with all Shopify themes out of the box. All charges are billed in USD. Recurring and usage-based charges are billed every 30 days. Meets our highest standards for performance, design, and integration.

  Homebrew 6.0.0▲1,481

  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!

  Performative-UI – A react component library of design tropes▲1,181

  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!
