Reviewer scorecard
“Limited API compared to Mailchimp. Fine for creators but not enough flexibility for custom integrations.”
“No API to speak of. It's a publishing platform, not a developer tool. Built-in audience is the value proposition.”
“Built for how creators actually work — visual automations, landing pages, and commerce all in one. The best in its niche.”
“The simplest way to start writing and getting paid. The network effect brings readers you wouldn't find elsewhere.”
“Focused product that doesn't try to be everything. For solo creators and small teams, it's the right choice.”
“10% revenue share is expensive at scale, but the built-in discovery and reader network provide real value.”
