About BWorlds
BWorlds reviews AI-built apps before real users arrive, monitors what happens after launch, and ranks the fixes to make next.
Why we started
Tools such as Lovable, Bolt, Replit, Base44, and Claude Code let one person turn an idea into a working application in days. When real users arrive, that builder also becomes responsible for security, data protection, errors, operating costs, and every change that could break an existing feature.
Emmanuel Marboeuf and Dorian Ouvrard founded BWorlds after seeing the same production work appear around every launch. Emmanuel spent three years in cyberdefense, then co-founded a SaaS company in the United States and led its engineering team for ten years. They built BWorlds so the checks normally run by an experienced technical lead keep running after launch, rather than being commissioned only after an incident.
BWorlds runs alongside the tools builders already use. Builders keep their code and product decisions. BWorlds reviews the app, watches its production behavior, and ranks the issues that need attention.
Founders
Co-founder
Emmanuel worked in cyberdefense before co-founding a SaaS company in the United States and leading its engineering team for ten years. At BWorlds, he brings that production experience to builders shipping with AI.

How we operate
Before wider use, BWorlds reviews security, reliability, data protection, performance, costs, and code quality. After launch, it watches uptime, errors, affected sessions, and connected code changes. New releases trigger new checks, and the findings stay ordered by impact.
BWorlds checks the parts a browser preview cannot prove: exposed secrets, access controls, data handling, slow queries, unbounded costs, fragile dependencies, and code that becomes harder to change.
Each release can change the risk. BWorlds watches uptime, errors, affected user sessions, and connected code changes, then flags what changed and who is affected.
Findings are ranked by impact. Each one includes a diagnosis and a fix prompt the builder can use in Lovable, Bolt, Replit, Base44, or Claude Code.
The company
BWorlds serves solo builders, agencies shipping client applications, and companies reviewing apps built by employees or vendors.
