Disclosure

Transparency about links, funding, and your data — per FTC guidance.

ratelimitlens is free. Some outbound links — for example to API gateways, observability or rate-limit middleware tools — may be affiliate links: if you sign up through them we may earn a commission at no extra cost to you. Paid links are marked rel="sponsored nofollow".

We only link to tools we'd actually use, and a commission never changes what we recommend or what the parser reports. Every interpretation follows the published methodology.

Your privacy: this is a static, client-side tool. The headers you paste are parsed in your browser and are never uploaded — there is no backend and nothing is logged.
