Handy References for Building Websites
This category mixes quick references with small builders. When a server returns an unfamiliar code, the HTTP Status Codes reference explains it in plain words. When you set up downloads or an upload form, the MIME Types Lookup gives the right content type, such as application/pdf for PDF files.
For pages you publish, the Meta Tag Generator writes title, description, Open Graph and Twitter Card tags and previews how they look. The HTML WYSIWYG Editor lets you format text with a toolbar and copy the HTML it creates. That is handy for a CMS field that only accepts HTML.
Some tools help with odd jobs. The Safelink Decoder unwraps links rewritten by Microsoft SafeLinks or Google AMP, so you can see the real address before you click. The Emoji Picker copies any emoji and shows its Unicode code point. The ULID Generator creates IDs that sort in the order they were made.
