# Why I left my SaaS stack
Five subscriptions. Five editors. Five companies
owning fragments of my audience.
I went back to Markdown. Here's what changed.Each post, product, and tier is its own Markdown file.
Built different. On purpose.
Three architectural decisions that separate Sentilis from every CMS, website builder, and link-in-bio tool you've used before.
Markdown files, four modules
Your bio, blog, store, and memberships are folders of plain .md files. Edit one, deploy all. No dashboards, no databases, no 'where did I put that?'
Bring your own editor
Use VSCode, Obsidian, vim, or whatever you already love. We don't build editors. We publish what you write, where you write it.
Offline-first by design
The canonical copy lives on your hard drive. When our servers go down, you keep writing. When you leave Sentilis, you walk away with everything in plain text.
Why not just use…?
Honest answers for the alternatives you're already considering.
vs. Substack
Substack owns your subscriber relationship and takes a cut of paid subs. With Sentilis, your audience is yours. Export to plain text anytime. We never touch your revenue.
vs. Notion
Notion sites are a workaround, not a product. Slow load times, limited customization, and your content is locked in their database. Sentilis files are forever-readable plain text.
vs. the 5-tool stack
Five subscriptions, five editors, five companies owning fragments of your audience. Sentilis is one folder, one CLI, one source of truth. Roughly $40/month → $12/month.
vs. building it yourself
Custom stacks are great until maintenance becomes a tax on your creativity. Sentilis gives you the ownership of static sites with the ergonomics of a managed product. No build configs to debug.
