FlowRail — Bob’s story

An illustrated story with a fictional creator and real recorded FlowRail staging examples. Narrated by ElevenLabs stock George.

Meet Bob. He's been building an invoice app with Claude Code. He describes what he wants, tries things out, and watches his idea take shape. Now, he'd love for other people to use it.

But there's something he can't tell just by looking at the screen. Is the code protecting the information people will trust him with? What if someone could open another business's invoices? Suddenly, sharing his creation feels like a much bigger step.

Then Bob discovers FlowRail. He installs it, connects it to Claude Code, and keeps building, with security guardrails based on what he and Claude agreed to create.

Together, they write down the plan: each business should only be able to see its own invoices. FlowRail reviews that design and turns its security requirements into checks on the code Claude proposes.

Here's why that matters. A proposed change could let someone reach another business's records. FlowRail spots the mismatch, stops the write, and explains the problem. That unsafe version never reaches the file.

The feedback goes straight back to Claude, so it can revise the code. Bob can follow the issue without having to discover it after someone else's information is exposed.

The guardrails extend to the packages his app depends on, too. FlowRail can stop supported installs of packages with known vulnerabilities before they're added to the project.

And Bob doesn't have to take any of this on faith. In the dashboard, he can follow the original requirement, see which change was blocked and why, and understand what still needs attention. The evidence stays connected to the plan.

Bob has more than a working screen now. He has a way to bring security into the decisions he makes as he builds. With FlowRail alongside Claude, he can get back to creating. FlowRail. Keep your AI true to the plan.
