FAQ
What technology does Notion use?
The hosting, CDN and framework signals we can detect from notion.so's public HTTP responses are listed in the "Detected stack" section above. They are read from the site's own responses at load time, so they reflect what Notion exposes publicly, not a definitive or complete stack list.
Is notion.so safe?
This page reports notion.so's publicly observable security-header hygiene as a letter grade, shown above. Security headers are one signal of good front-end practice, not a full security audit, and they say nothing about Notion's internal systems or data handling. Treat the grade as informational.
What are the best alternatives to Notion?
Widely used alternatives include Coda, Obsidian, Confluence. The right choice depends on your workflow, budget and team size.
