In plain words
Polar is an open source monetization platform that enables developers to quickly set up crowdfunding, memberships, digital products, and SaaS offerings. It handles billing, upselling, and international tax compliance, allowing creators to focus on product development rather than backend infrastructure.

An open source alternative to Lemon Squeezy with better pricing. Built for developers to offer crowdfunding, memberships, digital products and SaaS within minutes. Stay focused on shipping your passion - leave upsales, billing and international taxes to us.
Polar is the Merchant of Record for developers building AI-era software: payments, subscriptions, and usage-based billing, with global tax handled for you.

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…
