Know whether your app is ready for real users.
Start with your URL, then connect your code for a deeper review across security, reliability, data, performance, costs, and code quality.

BWorlds audits your apps, gets them ready for the real world, monitors them 24/7, and shows you exactly what to fix when something goes wrong.
Running apps for a team or for clients? Book a demo
A demo of BWorlds in four moments. You paste your app’s link, BWorlds recognises the app and starts First Look. The audit finds that the database can be read without logging in and gives a repair prompt. The prompt goes into an AI builder, the fix is published, and BWorlds verifies it on the live app. Then BWorlds keeps watch: when the app gets slower after a publish, a warning email offers the fix, and once it is published BWorlds verifies that response times are back to normal.

The second job
Your app went live with a second job attached.
As your app grows and real people use it, more and more of your time goes into fixing instead of building. And every fix can create the next problem.
None of these are building. All of them land on you.

How BWorlds works
You keep building. BWorlds keeps watch.
Specialized agents and experienced playbooks audit your app’s weak points with CTO-level rigor, keep watch while it runs, and turn every finding into clear guidance and a fix prompt for your building tool. You go back to being a builder.
02 · Run
Know what happens after you publish.
Keep watch over uptime, errors, affected user sessions, and connected code changes. When something breaks, you hear it from BWorlds, not from a customer.
03 · Improve
Keep strengthening the app as it grows.
Reassess the app as it changes. Get prioritized recommendations that improve performance, reliability, code quality, data protection, and operating costs over time.
Your app has
- Security
3 paid AI routes skipped login and credit checks
A request flag let people use paid features while the usage still landed on the builder’s bill.
- Reliability
A sign-in request failed after a publish
BWorlds detected recurring database errors on the endpoint 8 minutes after the change. The app itself stayed online.
- Performance
The page sent a new database request for every row
The list became slower as it grew because related data was fetched one row at a time instead of in one batch.
- Security
The same access gap affected 3 routes
Checking related endpoints showed the first issue was not isolated to one paid feature.
- Reliability
Sign-in errors dropped to 0 after the fix
The failing endpoint recovered and the error did not return for the rest of the day.
Someone oncall now.
Expert playbooks. Applied to your app.
BWorlds turns experienced engineering practice into repeatable reviews that keep working across launch, day-to-day operations, and every version after.

Get Ready for Real Users
Emmanuel Marboeuf
Co-founder of BWorlds. 10 years as a CTO, cyberdefense background.
The full pre-launch review: we map your app silently, ask you what can never break, then dig where your business is actually exposed. You get a ranked fix list, not a 40-page report.
BWorlds
Keep Shipping Without Breaking Things
Dorian Ouvrard
Co-founder of BWorlds. AI engineer and tech lead.
A structure review of what the AI built: components doing too many jobs, the same logic written three ways, risky dependencies. So your next prompt doesn’t topple the last ten.
BWorlds
Never Wake Up to a Five-Figure Bill
Emmanuel Marboeuf
Co-founder of BWorlds. 10 years as a CTO, cyberdefense background.
Hunts down every way your app can spend money without asking you: AI keys visible in your code, paid features with no caps, uploads with no limits. Each leak closed and verified shut.
BWorlds
Stop Burning Credits on Failed Fixes
Dorian Ouvrard
Co-founder of BWorlds. AI engineer and tech lead.
Audits what makes building with AI expensive: oversized components the AI rereads on every prompt, the same logic in three places, fixes that keep breaking something else. Clean structure makes every prompt cheaper.
BWorlds
Make Your App Feel Fast
Dorian Ouvrard
Co-founder of BWorlds. AI engineer and tech lead.
Finds the slowness users feel: pages that load everything before showing anything, heavy code shipped to every visitor, requests that run one by one. Slow is the first reason people leave.
BWorlds
Make It Safe to Charge Money
Emmanuel Marboeuf
Co-founder of BWorlds. 10 years as a CTO, cyberdefense background.
Every path to your paid features, checked for free rides: skipped logins, missing billing checks, customers charged for failed jobs. So usage lands on customer accounts, not on your bill.
BWorlds
See What a Stranger Can See
Emmanuel Marboeuf
Co-founder of BWorlds. 10 years as a CTO, cyberdefense background.
A read-only pass over everything your app shows the internet: exposed keys, customer data readable without login, doors locked only in the browser. Every claim verified, nothing touched.
BWorlds
Catch What a Publish Breaks
Dorian Ouvrard
Co-founder of BWorlds. AI engineer and tech lead.
Errors, live user sessions, uptime and your latest changes, read together. When a publish quietly breaks sign-in, you know in minutes, with the exact change that caused it.
BWorlds
Keep Each Customer’s Data Theirs
Emmanuel Marboeuf
Co-founder of BWorlds. 10 years as a CTO, cyberdefense background.
Verifies the walls between your users: who can read, change or delete which records, tested from the outside and traced in the code. The gap we find most often in AI-built apps.
BWorlds
Survive Your Growth Spurt
Dorian Ouvrard
Co-founder of BWorlds. AI engineer and tech lead.
Spots what works with ten users and collapses with a thousand: pages that load whole tables, lists that query row by row. Fixed in impact order, before growth turns them into your first outage.
BWorlds
Stay Right with Privacy Law
Emmanuel Marboeuf
Co-founder of BWorlds. 10 years as a CTO, cyberdefense background.
What personal data you collect, where it goes, and whether tracking waits for consent. Reviewed before a customer, a partner or a regulator asks the question.
From builders
What changes when BWorlds is watching.
I run a paying AI product without a technical team. BWorlds found three ways people could use it for free and gave me the exact fixes. Now I trust it’s safe to charge for.
JulienFounder, insAItI built our production app with no coding background. BWorlds found risks I had no way of seeing, and I closed them without slowing down. Now I can keep shipping fast and safely.
Pierre TucoulatCo-founder, The Good FabWe built our apps ourselves, without engineers. BWorlds caught two serious issues one day before our first client would have hit them. Now I stop worrying about what I don’t know.
AnonymousCOO, second-hand fashion marketplaceWho BWorlds is for
Peace of mind for every app, at every stage.
- Check readiness before real users arrive
- Catch security, reliability, data, performance, cost, and code-quality issues
- Get clear guidance and fix prompts for your building tool
- Keep watch over uptime, errors, and affected user sessions
Your app stays yours and remains in your building tool. BWorlds investigates issues, gives you the guidance and fix prompt, and verifies the result wherever possible. Supported remediation can be handled with your approval as that capability expands.
No. Start by pasting your live URL for a free external check. Connect GitHub when you want deeper findings, change detection, and guidance tied to the code itself.
BWorlds watches app health, uptime, errors, and live user sessions. GitHub integration detects connected code changes. The SDK captures runtime errors and session context when installed.
Every finding has an “I have fixed this” action. BWorlds checks the code change or the live website when the issue can be verified. For changes inside a third-party service, BWorlds may rely on your confirmation.
BWorlds applies specialized agents and experienced playbooks to recurring technical work around your app. It does not replace technical leadership, product decisions, architecture ownership, or feature development.
No. BWorlds provides a practical technical baseline and continuous oversight. It helps find common security, reliability, data, performance, and code-quality problems. It does not replace a formal penetration test or compliance certification when those are required.
