What are Web Tools?
The small things that bite while building for the web โ non-ASCII breaking a URL, a special character being eaten as a tag, a shared link showing the wrong preview. Paste it in and see what's actually happening.
When you need them
- A URL breaks once it contains non-ASCII characters
- Special characters render as tags instead of text
- A shared link shows the wrong title or thumbnail
- You want to preview markdown before publishing it
