Your SaaS or marketplaceBubble has grown.Will Bubble scale with it?

Scroll has been building Bubble applications since 2021. We know what the tool can do—and we also know when costs, performance, or data sovereignty justify switching to a custom stack.

01 — What we do

Three scenarios
where we step in on a Bubble project.

Build, stabilize, or scale. The right move depends on where your app stands and what it needs to handle tomorrow—not a pre-set sales pitch.

01

You're starting from scratch

Bubble remains a relevant choice for quickly validating a concept: SaaS, marketplace, internal tool. We build with an architecture that won’t close the door to future migration.

02

Your Bubble app is causing issues

Degraded performance, broken workflows, rising monthly bills, developers unable to read editor pages. We audit, stabilize, and propose a plan.

03

You’ve decided to move on

The decision is made: it’s time to migrate to code. We take the business logic built in Bubble—workflows, roles, rules—and rebuild it on Next.js and Supabase without reinventing everything.

02 — The true cost at scale

What Bubble doesn’t tell you
in its pricing page.

Bubble is an excellent tool to get started. But its model has four blind spots that aren’t visible in an MVP and become costly in production. Better to know them before they catch up with you.

01

Usage-based billing

Bubble bills by number of "workload units." A slightly complex workflow on real-world volume can multiply the bill by 5 or 10 compared to the initial plan. Predictable for an MVP, uncontrollable in production.

02

Your data hosted in the United States

Bubble stores data on AWS us-east. For health, financial, or contractually sensitive data, this is a real blocker—not a technical detail.

03

Performance under load

Bubble handles concurrency via its own shared servers. Beyond a few hundred simultaneous users, response times degrade with no developer-side levers to fix it.

04

Generative AI beyond the sandbox

Connecting a real AI assistant, RAG on your data, or business agents to Bubble requires fragile workarounds. It’s not the platform for that.

03 — Migration stack

What we're migrating to.

Each Bubble component has a clean, versioned, and self-hosted equivalent. We don’t recover the visuals—we rebuild the features on a maintainable foundation.

What Bubble doesWhat we build instead
Visual database + workflows→Supabase (PostgreSQL) + Node.js API
Bubble Authentication→Supabase Auth, Auth0
Visual interface→Next.js, React, TypeScript
Third-party plugins (payment, email, storage)→Native Stripe, Resend, Supabase Storage
Shared US hosting→OVH, Scaleway, Vercel—sovereignty based on needs
No native AI→Native LLM (Mistral, OpenAI, Claude) + n8n
Adaptable target based on your context—IT team, existing infrastructure, GDPR constraints, or sovereignty. The source code returns to your Git.

Frequently Asked Questions

The most common questions we get during scoping. If yours isn’t here, reach out!

When the Bubble bill exceeds €500 to €800/month, the comparison with a custom infrastructure starts to tip in its favor. We’ll recalculate together during scoping—factoring in development, hosting, and runtime costs over 3 years.

No. Bubble doesn’t generate exportable code. Unlike WeWeb or Plasmic, everything stays within the platform. A Bubble migration means rewriting based on the existing logic—not exporting files.

A medium-sized SaaS with 5 to 10 role types and established business logic: 3 to 5 months. We migrate module by module—never a big bang that disrupts service.

Yes, that’s actually our default approach. The Bubble app keeps running while we build the coded version. The switch happens module by module, with validation at each step.

Yes. We start with an audit of the existing setup: analyzing workflows, mapping roles and data, and identifying points of fragility. The technical context isn’t ours—we reconstruct it.
