“So I speedran a SaaS over the weekend using Claude Code — totally forgot I had my Stripe key hardcoded in a config file. Guardrail caught it before I even pushed to GitHub. I literally would've shipped that to production.”

Indie Maker
“I don't know anything about security honestly. I just want to get my app out there. Guardrail basically explains stuff like I'm five — here's the problem, here's how to fix it, done. That's all I needed.”
James L.
Solo Founder
“Ok the MCP thing is really nice. You literally just tell Claude to scan your project and it does it. I used to just... not do security? Like at all. Now it takes me 10 seconds so I actually do it.”
Mina P.
Vibe Coder
“A client hit me with the 'so is this secure?' question mid-demo and I panicked lol. Started using Guardrail after that. Got my grade from a C to an A, and now I just screenshot it and send it over. Clients love a letter grade apparently.”
David R.
Freelance Developer
“I have like 3 projects running right now and they're all on the free tier which is nice. Got a real-time alert at 3 AM that someone was hammering my login endpoint. Would not have noticed that on my own.”
Yuki T.
Side Project Builder
“We were two days from launch and nobody on the team had thought about rate limiting. Guardrail flagged it and walked us through the fix step by step. Took maybe an hour. Kind of embarrassing we missed it but glad something caught it.”
