Choose the tool that fits the work
Fermium vs Stacktree for sharing AI-made HTML
Both tools can turn an HTML file made with AI into a hosted link. The decision is whether you want a focused page publisher or a workspace that also holds your team’s forms, files, notes, and Agents.

When Stacktree may fit better
If your main requirement is publishing HTML pages and a custom domain at a lower paid entry price, Stacktree is worth considering. Try the publishing flow with a representative page and review the current plan limits before deciding.
When to choose Fermium
Choose Fermium when the published page is part of a client or team workflow. Collect a brief and uploads in a client intake form, keep responses in a private table, gather feedback on a PDF or image, and publish the resulting report or browser tool from the same workspace.
Fermium’s Free plan is a practical way for two people to test that workflow. Team adds capacity and access controls for a larger workspace. Hosted Agent chat and Slack Agent work use AI credits purchased separately.
Check the app requirements before switching.
Fermium’s HTML hosting runs JavaScript in the browser. It does not run server functions, and App draft publishing is not available yet. Review the HTML publishing guide and sandbox limits with the tool you intend to share.
Start with one real document, test its access settings as a reader, and update it at the same URL. That exercise will tell you more about fit than a feature checklist alone.
