What a Bubble to Nuxt migration actually costs (and what inflates the bill)

The sticker-shock quote for a Bubble → Nuxt migration is rarely the real number. The difference between a clean cutover and a painful one is scope clarity, and the biggest line items are almost always the boring ones.

What the quote should itemize

• URL & SEO parity plan: every indexed slug mapped to a 200 or 301 before a single page ships.
• Data export, schema mapping, and dual-write cutover windows so revenue flows never stop.
• Auth migration (sessions, password hashes, SSO) with a rollback path if anything misbehaves.
• Payments and webhook cutover: Stripe, Paddle, and any recurring billing logic retested end-to-end.
• Observability and hypercare: dashboards, alerting, and a 1–2 week post-launch window in the quote.

What usually inflates the final invoice

Three surprises account for most overruns: undocumented Bubble workflows (business logic trapped in visual editors), third-party plugins with no server-side equivalent, and "just one more feature" added during the migration. The fix is ruthless scope hygiene up front: freeze features, migrate first, then innovate on the new stack.

How to validate a quote in 15 minutes

Ask any vendor to walk you through their cutover checklist, their rollback plan, and their URL parity spreadsheet. If those do not exist, the quote is a guess. If you want a senior second opinion on an existing quote, that is exactly the shape of conversation to bring to a discovery call.
