Overview — 01

We migrate no-code Bubble apps to production-grade Next.js + Supabase stacks. Zero data loss, 70%+ faster load times, infinite scalability.

Nothing gets thrown away carelessly. Every piece of data gets mapped and validated before the old app is retired. And the end result isn't just "a faster app" -- it's a production application you can hand to an engineering hire on day one, put in front of a compliance auditor, or scale past the point where Bubble's per-row pricing starts making your CFO nervous.

I've done this with SaaS apps carrying 80,000+ user records, fintech tools that couldn't afford a minute of data loss, and marketplaces where the Stripe billing logic alone took two weeks to untangle. The common thread: founders waited longer than they should have, and the migration still worked. But it's always cleaner when you start before the performance problems become customer complaints.

Bubble-to-Next.js Migration

So here's what a Bubble-to-Next.js migration actually is: you're taking everything you've built in Bubble -- every data record, every user relationship, every billing integration -- and rebuilding it into a codebase you actually own. We're talking a proper Next.js frontend with Supabase running Postgres on the backend, the whole thing sitting in version control where real engineers can touch it.

The gap — 02

What is holding your current website back?

Common gaps we find in nearly every audit.

Here's the thing -- when your workflow execution times are regularly hitting 5 to 8 seconds under normal load, that's not a tuning problem

Risk: That's Bubble's capacity unit model doing exactly what it was designed to do, which unfortunately means the only "fix" Bubble offers is paying more every month, and you still can't predict how much more. Slow response times at this stage aren't just annoying. They kill retention directly. And if a competitor built on a native stack is benchmarking 10x faster, you're going to lose the enterprise deals that require actual load test evidence -- and those deals are where the real revenue is.

Investors and acquirers want three things during technical due diligence: a GitHub repository, an infrastructure diagram, and penetration test results

Risk: Bubble can't produce any of them. That gap is a real problem -- not a theoretical one. Deals stall. Valuations get discounted. And when the data layer is opaque and the application can't be independently audited or handed off to an internal engineering team after close, that's not a negotiating footnote, it's a dealbreaker. We've seen this happen to founders in Austin, in London, in Toronto. The app was solid. The business was growing. But the stack made the whole thing feel unacquirable.

At some point you've hit a wall where every new feature either requires a Bubble plugin that adds fragility or a workaround that your team knows is held together with duct tape

Risk: And the real kicker? Engineers you bring on can't contribute to a Bubble app. Not meaningfully. So every new hire is essentially burning salary until the migration happens anyway -- which it will. Product velocity slows exactly when you need to be shipping faster. Bubble was never designed to support backend logic at the level a growing product needs, and eventually the workarounds start owning you instead of the other way around.

Safeguards — 03

How we build this right

Every safeguard, built in from Day 1.

Zero Data Loss Migration Protocol

Before we touch a single production record, we export and map every Bubble data type against the target Supabase schema. Row counts get verified, relational integrity gets checked in staging, and your live Bubble app stays fully operational until you've signed off. No surprises, no "we'll fix it after cutover" moments.

Stripe Billing Continuity

Your existing Stripe customers move over cleanly -- subscription intervals, trial periods, webhook endpoints, all of it. We transfer customer IDs and payment methods directly through the Stripe API, so nobody gets a cancellation notice and nobody is asked to re-enter their card. It's pretty straightforward in practice, though the webhook remapping usually takes a careful afternoon.

Owned Infrastructure, Auditable Code

The finished codebase lives in your GitHub organization under whatever license you want -- MIT, proprietary, your call. Supabase row-level security policies are fully documented, and before we hand anything over, the application passes standard OWASP static analysis. You're not inheriting a black box.

Scope — 04

What we build

Purpose-built features for your industry.

Schema Mapping and Postgres Migration

Bubble's flat-object model creates real problems at scale -- N+1 query patterns, slow dashboard loads, joins that should take milliseconds taking seconds. We reverse-engineer your existing data types and relationships into a properly normalized Postgres schema on Supabase. Honestly, this part of the process alone fixes performance issues that founders spent months trying to work around inside Bubble.

Next.js App Router Frontend Rebuild

UI components get rebuilt in Next.js using the App Router, and server components handle data fetching so your initial page payloads are actually small. Time-to-interactive drops measurably compared to Bubble's client-rendered output -- we're typically seeing 60-70% improvements on first load for apps that have been running on Bubble's Growth plan.

Auth and Role System Transfer

User records, roles, and permission logic all migrate to Supabase Auth, with row-level security enforcing the same access rules at the database layer. This closes the application-level permission gaps that are genuinely common in Bubble workflows -- the kind of gaps that don't show up until a penetration tester or a curious power user finds them.

API and Integration Handover

Every third-party API connection, Zapier trigger, and custom workflow gets documented during the audit, then rebuilt as proper Next.js API routes or Supabase Edge Functions. Secrets go into a real secrets manager -- not Bubble's plugin settings panel, which is honestly not where production credentials should live.

Our development process

From discovery to launch. Quality at every step.

Audit and Scope Definition

1 week

We start with a full audit: data types, workflow count, plugin dependencies, Stripe configuration, user volume. You get a written scope document with a fixed price and a specific list of every integration that'll be rebuilt or replaced. No "we'll figure it out as we go" -- you know exactly what you're paying for before anything starts.

Schema Design and Data Migration

1-2 weeks

The Postgres schema gets designed, reviewed with your team, and loaded into a staging Supabase project first. Then all Bubble records are exported and imported with row-count verification at every step. We don't touch production data until this stage has passed QA -- full stop.

Frontend and API Rebuild

2-4 weeks

Next.js pages, components, and API routes are all built against the staging database, replicating your existing user flows one by one. Stripe webhooks get pointed at the new endpoints and tested with Stripe CLI against live event fixtures. Nothing gets cut over until we've seen real webhook payloads behave correctly end-to-end.

Cutover and Handover

1 week

DNS cutover happens during a low-traffic window -- typically a Tuesday or Wednesday night. The Bubble app stays in read-only mode for 72 hours as a fallback while you watch the new stack under real traffic. Then you get the repository, full environment setup documentation, and a 60-minute recorded walkthrough of the codebase you can share with any future engineer.

Questions — 08

Frequently asked questions

Can I export my data from Bubble?

Bubble gives you two export options: CSV files and the Data API. We use the API. It preserves the relationships between your data types, handles large datasets without timing out, and lets us run incremental syncs during the parallel-run phase so nothing falls through the cracks. CSVs work as a backup, but they flatten out the relational context you actually need when you're building the PostgreSQL schema -- so they're a last resort, not a first choice.

How long does a Bubble to Next.js migration take?

Most migrations wrap up in 8 to 12 weeks for apps with standard complexity -- user auth, CRUD operations, Stripe payments, a handful of integrations. But add heavy real-time features, complex role hierarchies, or 50,000+ users and you're realistically looking at 12 to 16 weeks. We scope this precisely during the audit before we quote anything, so there's no ambiguity about which bucket your app falls into.

Will my users need to create new accounts?

No, users don't lose their accounts. We migrate records directly to Supabase Auth, preserving email addresses and profile data. The one honest caveat: Bubble doesn't expose password hashes, so users get a one-time password reset on first login. Takes about 30 seconds. And honestly? Most users won't notice anything except that the app loads faster.

Is Next.js + Supabase cheaper than Bubble long-term?

The cost difference is pretty significant. Bubble's Growth plan starts at $129 per month and can push past $500 for high-traffic apps -- plus the capacity unit spikes you can't predict. Supabase Pro runs $25 per month, Vercel Pro is $20. Most apps we migrate end up under $100 per month total, with none of the per-workflow or per-capacity-unit charges that blow up your budget right when you're getting traction.

What if my Bubble app uses plugins that don't have code equivalents?

Bubble plugins are just wrappers around standard APIs and JavaScript libraries -- there's nothing magical under the hood. During the audit we identify every plugin and map it back to the underlying service. Stripe, SendGrid, Twilio, OpenAI -- all of these have official SDKs that are more reliable and more configurable than their Bubble plugin equivalents. Custom plugins get rebuilt as utility functions. In practice this is one of the cleaner parts of the migration.

Can I migrate gradually instead of all at once?

You can migrate incrementally, but we'd talk you out of it. Splitting your app between Bubble and Next.js creates authentication and data sync headaches that aren't worth the perceived "lower risk." So instead we rebuild the full app, run both platforms simultaneously for one to two weeks with synced data, then cut over cleanly in a single window. Lower actual risk, none of the complexity of maintaining a split architecture that nobody fully understands.
