Migrate Base44 to Bubble: When to Switch No-Code Platforms

Bubble is the most mature no-code platform on the market, and the right destination if you want to leave AI-generated code behind entirely. This migration is unusual: you are not just changing backends, you are changing development philosophy. If that is not what you want, this is the wrong target.

If you are leaving base44 because the AI keeps breaking your code, Bubble eliminates that problem by removing the AI. If you are leaving because the platform is unreliable, Bubble has fourteen years of production hardening that base44 does not. If you are leaving because you want to write real code, Next.js + Supabase is the right move instead.

Why migrate to Bubble

Three reasons that justify the effort:

1. Mature no-code with proven production track record. Bubble has shipped tens of thousands of production apps over fourteen years. The platform is stable. The editor does not crash. The deploys are predictable. No regression loops because there is no AI making changes.
2. Plugin and marketplace ecosystem. Bubble's plugin store has thousands of pre-built integrations. Stripe, Twilio, Algolia, Mapbox, Calendly — all are one-click installs with visual configuration. Base44's integration story is much weaker.
3. Non-technical operators can edit it. You can hand a Bubble app to a product manager, an ops person, or a junior team member, and they can ship features. Base44 requires AI prompting skills that are surprisingly specialized in practice.

The trade: you lose the speed of prompt-to-feature development. Building a screen in Bubble takes hours of clicking, not seconds of prompting. For the right team, that is a feature, not a bug.

What you keep, what you rebuild

Layer	What you keep	What you rebuild
React components	Nothing — Bubble is not React	Every page in Bubble's visual editor
Routing	URL structure (sometimes)	Re-implement as Bubble pages
Schema definitions	Field names + types as reference	Recreate in Bubble's data tab
Database rows	Data (export to CSV, import to Bubble)	None
Authentication	User emails	Bubble handles password reset, sessions, OAuth
Backend functions	Logic as pseudocode	Rebuild as Bubble Workflows or API Workflows
File uploads	Files	Re-upload via Bubble Storage or external
Webhooks	Endpoint URLs	Configure inbound webhooks in Bubble
Scheduled jobs	None	Schedule API Workflows in Bubble (built-in)
Frontend logic	Nothing	Workflows, conditional logic, dynamic data
Custom integrations	Credentials	Plugin or API Connector setup

This is the migration with the lowest carry-over. Plan accordingly.

Architecture: source vs target

Base44 (current):

[browser] → CSR React (base44 hosted)
              ↓
        @base44/sdk
              ↓
       base44 backend (managed, opaque)

Bubble (target):

[browser] → Bubble app (proprietary runtime)
              ↓
       Bubble visual editor controls everything
              ↓
       Bubble database (managed, structured types)
              ↓
       API Workflows + Workflows (visual logic)
              ↓
       Plugins + API Connector (third-party integrations)

Bubble is fully self-contained. There is no code in the traditional sense. Logic is configured in a visual workflow editor. Data is queried in a visual query builder. The mental model shift is the migration's biggest cost.

Step-by-step migration plan

Phase 1 — Discovery (Week 1)

1. Document every screen, workflow, and integration

Bubble migrations live or die by upfront specification. You are not porting code; you are specifying behavior to rebuild from scratch.

For each screen in your base44 app, capture:

• URL path
• Layout (rough wireframe is fine)
• Data displayed and where it comes from
• Actions available and what they do
• Conditional logic (e.g., "show button only if user is admin")

For each backend function:

• Trigger (manual, webhook, scheduled)
• Inputs
• Logic in plain English
• Outputs / side effects

For each integration:

• Service (Stripe, Resend, Slack, etc.)
• Inbound or outbound
• Auth method
• Endpoints called

This document is forty to eighty pages for a typical app. Without it, the rebuild stalls in week two.

Phase 2 — Bubble setup (Week 1)

2. Create the Bubble app

Sign up at bubble.io. Create a new app. Pick the appropriate plan; you cannot use a custom domain or remove Bubble branding on Free.

Pick a starter template if one matches your shape, or start from blank. Bubble's responsive editor takes a learning curve to navigate efficiently; budget ten to twenty hours of editor familiarization for a developer who has not used it before.

3. Define data types

Bubble's data tab is where your schema lives. For each base44 entity, create a Bubble Data Type with matching fields.

Bubble field types you will use most:

Bubble type	Maps from base44
text	string
number	int / float
date	datetime / date
yes/no	boolean
User (built-in)	user reference
(custom data type)	foreign key reference
List of (type)	array of references
file	file upload
image	image

Define privacy rules per data type. These are Bubble's RLS equivalent — who can see, create, modify, delete each row. Get this right or your data leaks.

Phase 3 — Page rebuild (Weeks 2–6)

This is the bulk of the work. For every page in your base44 app, rebuild in Bubble's editor.

4. Rebuild pages one at a time

Start with the simplest page (often the auth screen or a static "about" page). Get fluent with the editor. Then tackle pages in dependency order: pages with no dependencies first, then pages that depend on those.

A typical app has fifteen to forty pages. Plan one to four hours per page in Bubble, depending on complexity. Plan more for any page with non-trivial responsive layouts or many conditional states.

5. Rebuild workflows

Bubble's Workflow tab is where you define what happens when buttons are clicked, forms submit, or conditions change.

For example, the base44 backend function:

// base44 function
export default async function handler(req: Request) {
  const { project_id, amount } = await req.json();
  // create stripe invoice
  // insert into invoices table
  return Response.json({ ok: true });
}

Becomes a Bubble API Workflow:

1. Trigger: Backend Workflow create-invoice exposed as API
2. Action 1: Stripe plugin → "Create invoice" with project ID and amount
3. Action 2: "Create a new thing" → Invoice with project, stripe ID, amount
4. Response: success

Configure visually. No code. The logic is the same; the syntax is point-and-click.

6. Configure plugins

Install plugins from Bubble's marketplace for every third-party integration. Common ones:

• Stripe — payment processing, subscriptions
• SendGrid / Postmark — transactional email
• Twilio — SMS, voice
• Algolia — search
• Mapbox — maps
• Calendly — scheduling

Each plugin has its own configuration. API Connector is the fallback for any service without a dedicated plugin — you define endpoints visually and Bubble generates the integration.

Phase 4 — Data backfill (Week 6)

7. Export from base44, import to Bubble

Export each base44 entity to CSV. Map columns to Bubble data type fields. Use Bubble's bulk CSV upload (in the Data tab) to import.

For relationships (foreign keys), Bubble can match by unique identifier on import. Import parents first, then children.

# example: export pipeline
1. base44 dashboard → export users → users.csv
2. base44 dashboard → export projects → projects.csv (has owner_id column)
3. clean CSVs (normalize timestamps, fix encoding)
4. Bubble Data tab → upload users.csv
5. Bubble Data tab → upload projects.csv (Bubble matches owner_id to user unique IDs)

For large datasets (>50k rows), Bubble's CSV upload is slow. Use the Data API instead, with a script that POSTs rows in batches.

Phase 5 — Auth migration (Week 7)

8. Migrate users

Export user emails from base44. Bulk-create User records in Bubble. Trigger a "set password" email to every user via Bubble's built-in password reset workflow.

Users land on a "set your new password" page on first login after the migration. This is the same approach as every other migration target — base44 does not export password hashes, so you cannot do better.

For OAuth users (Google, etc.), configure Bubble's social login providers with the same OAuth client IDs. Users re-link by email automatically.

Phase 6 — Domain and cutover (Week 8)

9. Configure custom domain

Add your domain in Bubble's Settings → Domain. Update DNS to Bubble's specified records. SSL is automatic.

10. Cutover

Bubble migrations rarely run a true dual-run because the apps are not API-compatible. The standard pattern:

1. Deploy Bubble app on staging subdomain (new.yourapp.com).
2. Run internal QA for one to two weeks.
3. Send a "we are migrating, expect downtime on Saturday morning" email to all users.
4. On cutover day: lock base44 to read-only, take final export, import any new rows since the last sync, swap DNS, validate.

Plan for thirty minutes to two hours of downtime. Bubble migrations are less smooth than code-to-code migrations; communicate clearly with users.

Phase 7 — Sunset

11. Decommission base44

Cancel after thirty days of stable Bubble production. Keep base44 export for ninety days as cold-storage insurance.

Common pitfalls

1. Underestimating the rebuild time. Bubble migrations take longer than any other target because every UI element is rebuilt visually. A 20-page app is six to eight weeks, not three.

2. Privacy rule oversights. Bubble's privacy rules are powerful but easy to misconfigure. The default is "everyone can see everything"; tighten before going to production. Test with at least two distinct users.

3. Workload unit overruns. Bubble bills compute by Workload Units. Inefficient workflows (especially "Schedule API Workflow on a list") burn units fast. Profile your workflows before launch.

4. Plugin quality variance. Some Bubble plugins are excellent. Some are abandoned. Verify the maintenance status before depending on a plugin for a critical integration.

5. Responsive design surprises. Bubble's responsive engine is more constrained than CSS Flexbox/Grid. Some layouts that worked in your base44 React app are awkward to recreate. Plan for design compromises.

6. SEO penalty if unconfigured. Bubble apps can render server-side now, but the default is client-rendered. Enable SEO settings explicitly and configure meta tags per page, or you ship a Google-invisible app.

7. Backup discipline. Bubble has built-in versions but no automated off-platform backup by default. Configure scheduled CSV exports of every critical data type to an external storage service.

Timeline + team

Six to ten weeks with this team:

• One Bubble developer (or a senior dev willing to learn Bubble fast). Owns the rebuild. Forty hours per week.
• One product owner. Validates feature parity. Ten hours per week. This role is heavier than other migrations because the rebuild surface is larger.
• One designer (optional). For apps with complex UIs that need responsive rework.

If your team has no Bubble experience, budget two weeks of learning curve before the migration starts.

Cost

Migration tiers:

Tier	Price	What you get
Small	$6,000	6 weeks, simple app, standard plugins
Medium	$12,000	8–10 weeks, custom integrations, complex workflows
Enterprise	$25,000+	Compliance constraints, complex roles, custom plugins

Bubble: $29/mo (Starter), $119/mo (Growth), $349/mo (Team). Workload usage variable. Total ongoing: $30–$500/mo depending on traffic.

DIY vs hire decision

DIY this if:

• You or someone on your team has shipped at least one production Bubble app.
• Your app has under twenty pages.
• You can spare six to ten weeks of focused time.
• The development philosophy shift (visual no-code) is what you want.

Hire help if:

• You have never used Bubble.
• Your app is complex (40+ pages, intricate workflows).
• You need it done in under six weeks.
• The current team is fluent in code but not in visual development.

This is a migration where hiring an experienced Bubble developer is often dramatically cheaper than the time-cost of learning Bubble for a senior code-first engineer. Bubble fluency takes 100+ hours to develop properly.
