Secrets leak every day. API keys committed by accident, .env files included in repos, connection strings pasted into Slack. Not because the people who ship software are careless. Because the feedback loop between writing code and finding mistakes is too slow and too expert-dependent.
Existing tools are built for security teams: CLI tools that need configuration, scanners that require CI setup, rules that need tuning. The indie hacker shipping alone has none of that infrastructure. Neither does the startup racing to launch.
We built NULLO to close that gap. Paste your content, get a plain-language report in seconds. No account, no setup, no security background required. The barrier to knowing should be zero.
Make security feedback instant and accessible for every person who writes or ships software.
Four principles that guide every decision.
Instant over elaborate
A scan you can run in ten seconds will be run. A tool that needs an hour of configuration will not.
Plain language over jargon
Every finding is written for the person who wrote the code - not for a security team that already knows what a CORS wildcard means.
Private over convenient
You should not have to choose between scanning sensitive content and trusting the tool. We do not store or log what you submit.
Broad over deep
One scan that covers secrets, PII, trackers, headers, and config is more useful than four excellent tools you never have time to integrate.
