Status and error page templates for SaaS products, web apps, and developer tools. A custom 404 not found page, a 500 server error page, a scheduled maintenance page, a status page, plus coming soon and waitlist pages for products that have yet to launch. Every template is plain HTML and CSS, so paste one into Claude Code, Replit, Lovable, ChatGPT Codex, Bolt, or Cursor and put your own product on it.
Frequently asked questions
What should a custom 404 page do?
Say plainly that the page was not found, then get the visitor moving again with links to the pages people actually want and a search box. A 404 is a navigation problem, so the fix is directions, not an apology.
What is the difference between a 404 page and a 500 page?
A 404 means the address is wrong, so the reader needs somewhere else to go. A 500 means your server failed, so the reader needs to know you have seen it and when it will be fixed. Different reader, different moment, different copy.
What belongs on a maintenance page?
When the work started, when you expect to finish, and a way to be told when it is done. Anyone who lands on a maintenance page is already inconvenienced, so give them a real window and let them get on with their day.
Which vibe coding tools work with these status templates?
All of them. Paste any 404, 500, maintenance, coming soon, or waitlist template into Claude Code, Replit, Lovable, ChatGPT Codex, Bolt, or Cursor and describe your product. The tool rewrites the copy and links while the design holds.
