About nocternal
nocternal is a small set of single-purpose tools for the files developers share when something breaks at 2 a.m.: logs, configs, pastes. Each tool strips or masks the secrets those files tend to carry — keys, tokens, passwords, emails, IPs — so you can hand them to a teammate, a ticket, or an AI chat without handing over your credentials too.
The trust mechanic
Everything runs in your browser. There is no server-side processing, no
account, and no upload — and you don't have to take our word for it. Every
page ships a Content-Security-Policy with connect-src 'none',
which means your browser itself refuses to let the page transmit
anything, anywhere. Open DevTools, watch the network tab while you use a
tool: after the page loads, nothing leaves.
Honest limits
Detection is pattern-based and best-effort. The tools catch common secret shapes and flag high-entropy strings for review, but no scrubber can guarantee a clean file. Review the output before you share it — every tool says this, because it's true.
