CashbackStacker

What it does

Most people use a cashback portal OR their credit card rewards. Almost nobody does both at once - and that's leaving 5-15% on the table every purchase. CashbackStacker shows you the exact combination: which portal is paying the most for your store today, which of your cards to use on top, and any active coupons. Takes 30 seconds. Free, no account needed. Rates update daily.

  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!
