Every organization has one internal tool everyone's embarrassed by: something written a decade ago in a language nobody wants to touch anymore, running on a server people forgot exists, that still decides whether payroll goes out on time. Nobody rebuilds it because there's no ROI story - until it breaks.
Vibe Coder solves the "rebuild" half of the problem: import the old codebase, the agent reads it in whatever language it's in, and regenerates an equivalent app on the platform. But rebuilding is only half the story. That old tool sat behind the company VPN for ten years. The new version needs the same level of privacy from day one - not as an extra project, but as a default.
The gap, with real numbers
We checked the official pricing and docs pages of a few tools on August 25, 2026. Here's what we found for restricting access to a deployed app, by IP or by country:
| Platform | IP allowlist | Country blocking | Price |
|---|---|---|---|
| Lovable | Not offered | Not offered | — |
| Bolt.new | Not offered | Not offered | — |
| Vercel | Paid add-on (Pro/Enterprise) | Not offered | $100/project/mo |
| Vibe Coder | Included | Included | No extra charge, every app |
Vercel charges separately for IP allowlisting and doesn't offer country blocking at all. Lovable and Bolt.new - app builders comparable to Vibe Coder - don't mention either capability on their pricing pages. If something's changed since, we're happy to correct it.
Why this matters for organizations
An internal tool doesn't need to be reachable from the whole internet for your team to use it. The problem is that on most tools, "private" means standing up your own VPN, WAF, or auth layer - extra work that's exactly why the rebuild project stays on the backlog.
With Vibe Coder, the order is reversed: import the old codebase, let the agent regenerate it, and before anyone outside the team sees it, restrict it to your office IPs or the countries your organization operates in. The new app is never, even for a moment, more exposed than the old one sitting behind the VPN.
How the access control actually works
- IP allowlist — IP addresses or CIDR ranges (IPv4 and IPv6). Enforced immediately, no Deploy required, and covers both the Preview environment and the app's data API. Signed-in editors are never locked out - it only affects anonymous visitors.
- Country blocking — a real CloudFront GeoRestriction, not an app-layer check. Applies to the deployed app, and takes effect on the next Deploy.
And the important part not to skip: the country block is IP-geolocation based, like any geo-block - a VPN gets around it. It's a convenience filter for casual access, not a security control. If you need real security, that starts with authentication and authorization, not an IP address. Both rules are available to every user, with no extra charge.
Frequently asked questions
Can I restrict an AI-generated app to just my company?
Yes. Every Vibe Coder app has its own optional IP/CIDR allowlist and country allowlist, set from the app's settings. Restrict it to your office network or a handful of countries and it applies immediately.
Is IP allowlisting really free on Vibe Coder?
Yes, it's included on every app with no extra charge. On general-purpose hosting like Vercel, the equivalent feature is a paid add-on billed separately per project.
Does the country filter replace real authentication?
No. It's IP-geolocation based, so a VPN gets around it, same as any geo-block. Treat it as a convenience filter that keeps casual/anonymous traffic out, not as a substitute for login and authorization.
What happens to the old tool while I migrate?
Nothing, until you're ready. Import the old codebase from a GitHub repo or a ZIP file, let the agent regenerate it, and lock the new app down before you ever point real users at it - the old tool keeps running until you cut over.
