So I chatted with the founders of LexasCMS recently (bootstrapped business for now!).
They built a new headless CMS, but I think it comes with very cool features like content personalization, content scheduling, and realtime in-app previews.
They have a good offering for some ecommerce use cases, too, so we'll collaborate with them on a post on our blog at Snipcart.
Anyway, just thought I'd share this indie Jamstack tool!
