Hey Product Hunt! I'm the maker of GritCMS. - I built this because I was tired of paying $200+/month across 5 different platforms just to run an online education business. Course hosting here, email marketing there, community somewhere else, and they barely talk to each other. - GritCMS puts everything under one roof and you host it yourself. That means: Your data stays yours. No platform can shut you down or hold your content hostage. Your costs stay flat. Whether you have 100 or 100,000 contacts, your server costs barely change. No more "upgrade to our $299 plan to unlock automations." - Everything is connected. When someone buys a course, they're auto-enrolled, tagged in your CRM, added to an email sequence, and their affiliate gets credited — all without Zapier glue. - The tech stack is Go + Next.js, so it's genuinely fast. The whole platform runs comfortably on a single VPS. I've been building this across 10 development phases and it's finally ready. I'd love your feedback what features would make this even more useful for your creator workflow? Happy to answer any questions!

Congrats on the launch, JB. The idea of a self-hosted creator OS that replaces several expensive tools is really appealing, especially for creators who want full control of their data.

A few things that could make it even stronger: built-in analytics for courses and funnels, integrations with tools like Zapier or webhooks for automation, and perhaps a plugin or theme marketplace so developers can extend the platform.

Also, a simple one-click deployment option (Docker or cloud templates) could make it easier for non-technical creators to get started.

Great work on building this with Go and Next.js - excited to see how it grows.
