The Great Replit Escape (VPS Fleet)

Claude Code audited all 27 Replit apps, hardened Joe's own servers, and migrated the keepers one by one: databases moved, logins swapped to magic links, rented AI proxies replaced with direct APIs.

The problem

27 apps scattered across Replit meant runaway costs and zero control.

What Claude Code did

Claude Code cataloged every app with a migrate, keep, or kill verdict, then built out the VPS infrastructure: nginx, SSL, firewalls, fail2ban, systemd services, nightly backups. Then came the migration wave: ten apps moved, each with its database exported and restored, rented platform logins replaced with email magic links, and platform AI proxies swapped for direct API keys. Every one verified live before the old copy was retired.

The result

A hardened fleet Joe owns outright, ten rescued apps running on it, and every service documented with its own runbook.

FAQ

Isn't server admin exactly what no-code was supposed to avoid?

It was โ€” until the admin became an AI. Claude Code does the sysadmin work; Joe does the deciding.

What happened to the other apps?

Killed or consolidated. The audit alone paid for itself.
