Your input stays yours
Text, JSON, colours, images and calculations are handled by your own browser. There is no upload step, no processing queue and no copy of your data on our disk.
Six website inspection tools are the exception: they ask our server to fetch a public URL because browsers cannot read another site's headers. Those requests are rate-limited, size-capped and blocked from private networks. The page always says which mode you are using.
Three facts, no marketing
- No account required for any published tool.
- Usage is counted per tool per day, never per person.
- No invented ratings, testimonials or download counts.
