Get ready for your next customers
The audit runs again as the product changes, so the next signature does not wait.
BWorlds for startups
Your first engineering hire that works 24/7.
BWorlds audits your product as it grows, watches it while customers use it, and fixes everything that breaks. All from one place.
Free to start. Your URL is enough, no code access. Not sure if this is for you? Check your fit.

Run
Know the moment your product breaks for a customer.
BWorlds watches uptime from the outside, catches every error with the session that hit it, and replays what the user did.
Know if your app is down
Checked around the clock, with a status page your customers can see.
Which error to fix first
Ranked by impact, tied to the change that caused them.
Replay what the user did
Watch the session behind a failure, click by click.
Fix it, and know it worked
Paste the fix into your AI tool. BWorlds rechecks after you publish.
Is BWorlds right for your app?
Tell us where your product stands. We will point you to the right next step. No email needed to see it.
BWorlds checks and monitors the app around the work you do in your builder. It does not build new product features for you.
What you actually get
Keep building without hiring.
BWorlds is an engineering teammate that already knows everything about your product, how it is used and its errors. It does not build features. Building stays in your AI tool.
See what breaks in real use
Uptime, errors and the sessions behind them, watched while customers are in the app.
Generate fixes, not tickets
Every finding comes with a BWorlds fix for your AI tool, checked again once you publish.
Improve every week by default
Architecture and code quality reviewed as the product grows, so each change stops breaking the last.
Launch
Always ready for the next customer.
Themed audits run on your product, chosen by its risk profile and by what you changed. What they verify assembles into a Trust Page, ready when a customer asks.

Assembled from your own results, open items included. You do not build it, and it updates when the app does.
Improve
Ship every week without breaking last week.
AI builders pile code up until each change breaks two others. It is the number one problem of AI-built apps. BWorlds reviews how the app is built, recommends the architecture that fits this product and where it is going, and writes the rules your AI tool follows from then on.
Start in minutes. No card. No code access.

With your developer
Give your first developer a senior team’s tooling.
Maintenance, security and on-call are already covered, so their days go to the product. From day one they get the findings, every error with its session, and replay.
Day one starts with context
The app’s findings, incidents and history are already recorded.
On-call is already covered
They are not the only person between your customers and a Sunday outage.
Their agent talks to BWorlds
A CLI and agent access, so findings reach the coding agent they already work in.
Replay and error sessions from the start
They debug from the session that failed, not a description of it.
The best engineering standards for your product.
Every audit runs on playbooks built from how the best engineering teams work: securing data, sizing a database, controlling cloud and AI costs, reviewing code before it ships.

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.
One plan

Tool ranges are public list prices as of September 2026, from the entry paid tier to a mid plan. Each has a free tier that a product with paying customers outgrows. The two people lines are typical contractor and on-call rates, and the total is the midpoint of every range. See the plans for what each one includes.

The questions founders ask.
One founder with paying customers and no engineer. That is the case it is built for.
Lovable, Bolt, Replit, V0, Emergent, Claude Code, Base44, and any app that answers on a URL. Connecting your GitHub adds the code-level findings and ties an incident to the change that caused it.
No. You keep building where you build. When you want the database, the logins and the hosting on accounts in your own name, that migration is included in the annual Pro plan.
A monthly plan, plus credits you spend when BWorlds works on the app: the audit, a fix, checking the fix worked. You can start free.
One prompt, one moment. It cannot see production, it cannot tell you the fix worked, and there is nobody behind it when the answer is wrong. Same for the scan built into your AI builder.
Nothing changes unless you apply it. Your code stays on your GitHub.
You get the BWorlds fix ready for your AI tool, and BWorlds rechecks the app once you publish to confirm it worked.
No. Enterprise for apps inside your own company, Agencies for apps you build for clients, Builders if you are building on your own.
Building for a company's own teams? Enterprise. Building apps for clients? Agencies. Building on your own? Builders.
