Buttondown vs Kit (formerly ConvertKit)

Buttondown is a lean, developer-friendly newsletter tool for writers who want simplicity. Kit is a full creator marketing platform with landing pages, commerce, and automation. The choice comes down to whether you want a newsletter tool or a business platform.

Verdict

Buttondown is the indie darling — minimal, honest, and perfect if you just want to write and send. Kit is what you graduate to when you need automations, landing pages, and paid products. For pure newsletter writing, Buttondown wins on experience; for building a creator business, Kit wins on capability.
