About this tool
Find the RSS, Atom or JSON feeds of a website and validate one: required fields, dates, links, duplicate IDs and latest items.
If you enter a web page, the feeds it advertises as alternate links are discovered (and common addresses such as /feed are tried). The feed is parsed as XML without DTDs or external entities, or as JSON Feed, and channel, item and date fields are checked.
Example: check Feed or website URL = https://www.php.net/.
Feed readers are tolerant, so a feed with warnings may still work. Fix errors first.
Quick steps
- Enter the address of a public page or domain.
- Press Check. The 1CLIK server visits it, which can take a few seconds.
- Read each line — Good, Improve, Problem or Info — with a hint on what to fix.
1CLIK’s server fetches only the public address you enter. Private and internal addresses are refused, and results are cached for a few minutes, not saved to your account.
FAQ
How does the RSS Feed Validator & Finder work?
If you enter a web page, the feeds it advertises as alternate links are discovered (and common addresses such as /feed are tried). The feed is parsed as XML without DTDs or external entities, or as JSON Feed, and channel, item and date fields are checked.
What should I keep in mind?
Feed readers are tolerant, so a feed with warnings may still work. Fix errors first.
Why can the result differ from what I see in my browser?
The check sees what the server sends to 1CLIK, before any JavaScript runs. Sites can also answer automated requests differently, block them, or vary by country.
