Claude autonomously runs 12-hour app migration, initial design would cost $3,000/month
tristanbob · x · 2026-11-02
The author had Claude work autonomously for 12+ hours to migrate a moderately complex web app: writing code, testing, generating sample data, rehearsing backup/restore, improving things along the way, then migrating and verifying — showing agents manage whole migrations, not just code.
After completion, the author urgently asked Claude to cut costs: the initial design had glaring mistakes that would have cost $3,000/month with very few users. They also note the /goal feature could have reduced the pauses waiting for manual approval.
