Free tools for launching and running a product
Check how your links look when shared, where your URLs redirect, what Stripe will keep from a payment and how old a domain is. Every tool is free, works without an account and shows its sources.
Open Graph checker
Preview how a link looks on X, Facebook, LinkedIn and Slack, and find missing or broken og: and twitter: tags.
Redirect checker
Follow every hop of a URL's redirect chain with status codes, and spot loops, temporary redirects and HTTPS downgrades.
Stripe fee calculator
Work out Stripe's card fee and your payout, or the price to charge to receive an exact amount, for US, EEA and UK accounts.
Domain age checker
Find when a domain was registered, its exact age, expiration date and registrar from public RDAP and WHOIS data.
How these tools handle your data
The Stripe fee calculator runs entirely in your browser. The Open Graph and redirect checkers send the URL you enter to our server, which requests that public page and returns the result; the URL is not stored, apart from a cache of a minute or two for repeat checks. The domain age checker keeps a shareable result page for each domain it looks up. Analytics count tool use, never what you entered.
