AI App Launch Audit · Fixed price, quoted up front
Replit App Security Audit
Built your app with Replit Agent? Before real customers and real data arrive, our senior Brisbane-led team reviews your Replit app the way an attacker and a production support engineer would: secrets, databases, auth, deployment settings and the code Agent wrote while you weren’t looking.

Where Replit apps go wrong
What goes wrong in Replit apps before launch
Replit gives you an editor, an AI agent, a database, auth and hosting in one place. That speed is the point. It also means the settings that keep customer data safe are easy to skip, because the app works fine without them.
Keys in the code, not in Secrets
Replit’s Secrets tool encrypts API keys and passes them to your app as environment variables. Keys pasted straight into source files, or printed in logs, skip that protection entirely.
Production secrets that never got set
Secrets in the editor don’t automatically carry over to your published app. Production values live in the Publishing pane, so a launch can quietly run on test keys, or on none at all.
Development and production sharing data
Older Replit apps used one database for preview and production. Replit now separates them, but apps that predate the change, or were migrated in a hurry, can still blur the line between test data and real customers.
Access rules that live only in the UI
Agent often hides buttons rather than checking permissions on the server. If an API route returns another customer’s records when you change an ID in the URL, the database is effectively public.
Auth that’s switched on, not wired in
Replit Auth handles sign-in. Whether each page, API route and file actually checks who is signed in, and what they’re allowed to see, is still up to your code.
Object Storage and uploads
Files that customers upload, such as invoices, photos and IDs, need their own access rules. A guessable or shared URL is enough to expose them.
Deployment settings for real traffic
Autoscale and Reserved VM deployments behave differently under load, on cold starts and with background jobs. A demo with three users won’t show you which one your app actually needs.
Agent changes nobody reviewed
Replit Agent can make large, multi-file changes in one go. Without a human reading the diff, small security regressions slip in between versions you thought were finished.
A lesson worth learning
What the 2025 Replit Agent incident teaches every builder
In July 2025, an AI agent on Replit deleted a live production database during a declared code freeze, then wrongly reported that it couldn’t be rolled back. Replit’s CEO called it unacceptable, and the company moved quickly to separate development and production databases. The platform is better for it. The lessons apply to any AI-built app.
01
Keep the agent away from production
Agent should work against development data only. We check your app is set up that way, and that nothing in the code can reach production data from a development run.
02
Know your rollback before you need it
Replit can restore project state, but your customers’ data needs a backup plan you’ve actually tested. We check what exists and how quickly you could recover.
03
Don’t trust the agent’s own report
An agent saying “tests passed” isn’t the same as tests passing. We run the critical workflows ourselves, as a real user would.
04
Write down who can change what
Who can publish, who can see production secrets, who can edit live data. If it’s “anyone on the team”, we’ll help you tighten it.
Replit pre-launch checklist
9 things to check before you publish a Replit app
Work through these yourself, or hand the list to us. Every item is part of our Replit audit, along with the 100+ general checks on our AI App Launch Audit.
Check 01
Keys in Secrets, live values in production
Search the code and git history for keys and rotate anything ever committed, then confirm the published app uses live values from the Publishing pane.
Check 02
Separate production database
Real customers live in the production database only, and Agent can’t modify it.
Check 03
Server-side permission checks
Change an ID in a request. You should get “not allowed”, not someone else’s data.
Check 04
Every route needs sign-in
Check API routes and file URLs directly, not just the pages your menu links to.
Check 05
Uploads are private
Customer files can only be fetched by the people who should see them.
Check 06
Run Replit’s own scans
Use Replit’s built-in security tools and fix critical findings before publishing.
Check 07
Errors don’t leak detail
Stack traces, SQL and keys shouldn’t appear in error messages or browser responses.
Check 08
Rate limits on login and forms
Sign-in, password reset and contact forms need limits, or bots will find them.
Check 09
Backups you’ve restored
Take a backup, restore it somewhere safe, and time how long it takes.
Automated scanners, including Replit’s, are a good first pass. They can’t tell whether your access rules match how your business actually works. That takes a person who understands both.
How we audit a Replit app
How a Replit audit works
You share access, we do the digging, and you get a report you can act on straight away.
1. Access and scope
You invite us to the Replit app (or share an export) with read access to the code and a test login. We agree the price and scope up front.
2. Configuration review
Secrets, environment separation, database and storage access, Replit Auth wiring and deployment settings, checked against how the app is actually published.
3. Code and workflow review
Senior engineers read the code Agent wrote and walk every important workflow as a real user, then as someone trying to break it.
4. Report and re-check
Findings ranked by risk, with a plain-English explanation and fix guidance or ready-to-use prompts for Agent. Once fixes are in, we check again.

FAQ
Replit app audit questions
Is Replit secure enough for a production app?
Replit as a platform includes solid security tooling: encrypted Secrets, separate production databases, package protection and built-in scans. Most problems we see are in the app itself: access rules, key handling and untested workflows. That’s what an audit checks.
Doesn’t Replit’s Security Agent already do this?
Replit’s scans are worth running and catch real issues. They review code and dependencies; they can’t judge whether your permissions match your business, or whether a workflow leaks data in practice. We use automated tools as a starting point, then apply senior human judgement.
Do I need to move my app off Replit?
No. We audit apps where they are. If you’d rather host in Australia, or need more control later, we can help you move, but that’s your call, not a requirement.
What access do you need?
Read access to the Replit app or a code export, a test account for each user role, and a short description of who the app is for. We never need production customer data, and we’ll sign a mutual NDA first.
How much does a Replit audit cost?
The AI App Launch Audit is a fixed price, quoted for your app and agreed before we start. Fixes are optional and quoted separately.
Will you fix what you find?
Your choice. We can give you fix guidance and prompts so you or Replit Agent can make the changes, fix it ourselves, or split the work. Most clients choose a split.
Can you keep an eye on the app after launch?
Yes, through a separate product. If you're still prompting new features into your app with Replit, our AI Build Partner puts an engineer across it on a steady rhythm: they review what changed, build and fix alongside you, and release it to production monthly or fortnightly. Plans start at $1,800 a month ex. GST, with a three-month initial term and then month to month. The audit fee isn't credited against a plan; they're separate products for different needs.
