404Buddy
About this site
404Buddy is a practical reference and toolkit for people who hit confusing errors on the web: HTTP status codes, browser messages (Chrome, Edge, and friends), DNS and network failures, npm and build tooling, databases, APIs, and CMS issues.
We combine clear explanations with actionable steps so you can move from “what does this even mean?” to a fix—whether you’re debugging production, learning the basics, or shipping a side project.
Who it’s for
- Developers and operators troubleshooting real incidents
- Students and self-hosters learning how the stack fits together
- Anyone who pasted an error into a search box and got noise back
What you’ll find here
- Fix pages for specific errors and status codes, with context and next steps
- Free tools to check URLs, redirects, headers, robots.txt, sitemaps, and more
- Articles and hubs that tie concepts together without fluff
We’re not a substitute for your vendor’s docs or your security team’s policies—but we aim to be the friendly layer that gets you unstuck fast.
