Platform-specific · 5 days · From $1,500
A senior look at your Replit app, before it becomes business-critical.
Replit gets you to a working URL in an afternoon. The trouble starts when that URL is also the one your customers pay against. We audit secrets, persistence, deployment, scaling headroom, and what happens if you ever want to leave.
Who this is for
Founders running real workloads on Replit.
If you check two boxes, the audit is the right next step.
Real users
You have paying customers on a Replit URL
That's fine — for now. We check whether the platform fits your shape, and what to do before it doesn't.
Replit Agent
You shipped with the Agent
The Agent is excellent at scaffolding, less great at remembering security context across sessions. We re-check what stuck.
Considering a move
You're weighing leaving for Fly / Render / Vercel
We give you the honest, app-specific answer — including the option to stay.
What we check (Replit-specific)
Where Replit apps drift.
In addition to standard audit surfaces.
- Secrets handling. Replit Secrets vs .env vs Agent chat history.
- Deployment shape. Reserved VM, Autoscale, or Static — fit, cost, and limits.
- Replit DB / Postgres. Whether you're using the right primitive for your workload.
- Filesystem persistence. What survives a redeploy, what doesn't, and what shouldn't be there at all.
- Custom domain & SSL. Routing, redirects, and the case where Replit isn't the only origin.
- Auth flows. Replit Auth, Auth0, Clerk, Supabase Auth — whichever you picked, we read it.
- Background jobs & cron. Whether they run reliably on the plan you're paying for.
- Logging & observability. What's available, what's missing, and how to wire Sentry / Logtail.
- Public Repl exposure. If your Repl is public, who can fork your secrets?
- Cost ceiling. Plan, deployment hours, egress, autoscale spikes.
- Exit path. What it would take to move, and to where.
- Account ownership. Org vs personal account, billing email, recovery.
Red flags
Patterns we find on Replit weekly.
Most are 30-minute fixes once you know.
Your Repl is public and reads .env from disk
Everyone can read your repo. .env is in it. It's been there for months. Rotate today.
Files written to disk get wiped on deploy
User uploads, generated PDFs, logs — all gone on next push. We move you to object storage.
Replit DB used as a real database
It's a key-value store. It's not a primary DB for a paying-customer app. We migrate.
Autoscale deployment with no cost cap
One viral post can cost you a month of runway in a weekend. Cap it.
The billing email is the founder's personal Gmail
Founder leaves, account leaves with them. Move billing and ownership to a company-controlled mailbox.
You're using the .replit.app URL in production
Custom domain is one DNS record away. Do it before launch — and before the URL ends up in a customer contract.
