How to migrate your Bubble app to Next.js — a practical step-by-step

If you got this far on Bubble.io, you already know the value of speed-to-MVP. The reason you're reading this is the moment every successful Bubble app reaches: workflows time out under load, the Database tab can't be tuned, custom integrations need a real backend, and an audit asks for things the editor can't produce. The fastest fix isn't to fight Bubble — it's to take the product you already validated and re-platform it onto code you own.

We've migrated more than 100 Bubble apps to Next.js. The playbook below is what we hand to new senior engineers on day one. Follow it in order and your team will have a production-grade Next.js codebase in 4 to 8 weeks, with zero downtime and no user-visible regressions.

Step 1 — Inventory the app, not the editor

The first mistake teams make is opening the Bubble editor and starting to translate. The editor is a UI, not a spec. Instead, build an inventory: every page, every workflow trigger, every option set, every API connector, every plugin, every privacy rule. Treat the inventory as the contract for the migration.

• Pages and reusable elements — count them, screenshot the live UI for visual diffing later.
• Workflows — group by trigger (page-load, button-click, scheduled, API endpoint).
• Data types — schema, fields, privacy rules, custom states that act as fields.
• API Connector calls and Bubble plugins — these are your highest-risk migration targets.
• Privacy rules — these become row-level security or middleware, not afterthoughts.

Step 2 — Pick a target architecture

For 9 out of 10 Bubble apps, the right target is Next.js (App Router) + a typed ORM (Prisma or Drizzle) + PostgreSQL + a managed auth provider. Vercel is the default host. This stack mirrors Bubble's strengths (file-based routing, server-side workflows, hosted auth) while removing every weakness (locked database, opaque workflow engine, per-row pricing).

Step 3 — Port the data first

Data migration is the boring, irreversible part. Do it first, validate hard, and the rest of the project relaxes. We use a 4-step pattern:

1. 1Export every Bubble data type to CSV via the Data tab (or via the Data API for large tables).
2. 2Generate a Prisma schema from the inventory — every Bubble field becomes a typed Prisma column, every Bubble option set becomes a Prisma enum.
3. 3Write an idempotent loader that hashes each row's natural key and upserts to Postgres. Run it daily during the migration so the new DB is always within 24h of production.
4. 4Validate: row counts, sums of numeric columns, and a 1% sample of full-row diffs. If any check fails, fix the loader, never the data.

Step 4 — Translate workflows to Server Actions

A Bubble workflow is just a sequence of steps with conditional branches. In Next.js, that's a Server Action — a typed function with arguments, a return type, and full access to your database. Most workflows compress into 10–40 lines of TypeScript.

// app/actions/posts.ts
"use server";
import { z } from "zod";
import { auth } from "@/lib/auth";
import { db } from "@/lib/db";

const Input = z.object({ title: z.string().min(1), body: z.string().min(1) });

export async function createPost(input: z.infer<typeof Input>) {
  const session = await auth();
  if (!session) throw new Error("Unauthorized");
  const data = Input.parse(input);
  return db.post.create({ data: { ...data, authorId: session.userId } });
}

Step 5 — UI parity, not UI rewrite

Recreate the UI with the same component-by-component breakdown your inventory captured. Tailwind + shadcn/ui gets you to pixel-faithful in days, not weeks. Resist the urge to redesign during the migration — make it identical first, then iterate after cutover.

Step 6 — Cutover with zero downtime

Run both systems in parallel for at least a week. Set DNS TTL to 60 seconds. On cutover day, freeze writes to Bubble, run a final delta load, and flip the CNAME. Most users won't notice anything except that the page loads faster.

What you get on day one

After cutover, your team owns: a typed Next.js codebase with conventional commits, a Postgres database you can connect any tool to, a CI pipeline with tests for every workflow, and a hosting bill that scales with usage instead of with users. With migrations starting at $1,975, most clients see payback in a matter of weeks on platform-fee savings alone.

If reading this confirmed your suspicion that it's time to leave Bubble, the next step is a 30-minute scoping call. We'll send you a fixed-price plan within 48 hours.
