Most "Bubble vs custom code" articles are written by someone selling one of the two. I hold a Bubble developer certification and I write Next.js and Postgres every week, so I have no tool to sell you. I have built or extended seven products in Bubble and migrated one of them to code after it outgrew the platform. Here is how I actually decide, and the decision table I use with founders.
First agree what the MVP is for
An MVP has one job: find out whether people will pay for the thing before you spend the money to build it properly. If your "MVP" has to survive three years and handle thousands of concurrent users with audited data, it is not an MVP, it is version one, and the answer below changes.
So the first question is not Bubble or code. It is: what must be true in 90 days for this to have been worth it? If the answer is "ten paying customers and a clear list of what they want next", you are building to learn, and speed matters more than anything else.
Where Bubble wins
Speed to a working product. Bubble gives you a database, user accounts, hosting and a visual logic editor on day one. Forms, lists, dashboards, roles, invitations and Stripe checkout are days of work, not weeks.
Iteration while you talk to customers. Changing a screen or a workflow after a customer call takes an afternoon. That loop is what an MVP is for.
A founder can touch it. A non-technical founder can change copy, add a field or adjust a workflow without opening a ticket.
Two examples from my own work: Claire, a contract review product with team invitations, risk settings and an escalation queue, and Spinfluence, a QR prize wheel for restaurants with a multi-location owner dashboard and Stripe subscriptions. Both were built in Bubble (/work/claire and /work/spinfluence). Bubble was the right call for both, because the goal was a working product in front of users quickly.
Since its mobile launch Bubble also offers a native mobile track, so "we need an app in the stores" is no longer an automatic reason to leave the platform. Check the current plans at bubble.io/pricing, because they change.
Where custom code wins
Rules that must be exact and testable. A scheduling engine, a pricing engine, anything where "almost right" costs money. In code you write a test for every rule; in Bubble you click through it.
Data isolation between customers. If each customer must be unable to see another's data under any circumstance (health, legal, finance), Postgres row-level security is a cleaner guarantee than privacy rules layered on a shared database.
Integrations that must not fail silently. Webhooks with signature checks, retries and duplicate protection are ten lines in code and a workaround in a visual builder.
Predictable cost at volume. Bubble bills by workload units on top of the plan fee, and overage is charged per thousand units (confirm the current rate on bubble.io/pricing). Busy apps can find the bill hard to forecast. Coded apps on a database and a host have their own costs, but they scale with traffic in ways you can see coming.
Ownership. Bubble does not export your application as source code; your data exports, your logic does not. Code can be hosted anywhere and handed to any developer.
Anything outside the browser. Desktop tools, offline-first apps, heavy media processing.
The question most comparisons skip: who changes it after launch
Bubble is easier for a founder to change and harder to hand to an arbitrary developer; the pool of strong Bubble developers is smaller than the pool of React developers, though it is growing. Code is the reverse. Decide who will be making changes in month four, and choose the tool that person can work in.
Should I build my MVP in Bubble? A decision table
| If your MVP... | Lean towards |
|---|---|
| Needs to exist in four to six weeks and change weekly | Bubble |
| Is mostly forms, lists, a dashboard and a checkout | Bubble |
| Has rules you would describe as "it depends" and cannot yet write down | Bubble first, and plan the rewrite |
| Handles health, legal or financial data for several customers | Code |
| Depends on webhooks, retries or background jobs that must not drop | Code |
| Will be sold to a company that will audit the code | Code |
| Needs a desktop or offline component | Code |
| Will be edited by a non-technical founder after launch | Bubble |
Bubble MVP then rebuild: what it looked like on a real product
Clinical Stack, a staff scheduling product for clinics, started on Bubble. The first version proved that practices would pay. Then the scheduling rules, the messaging retries and per-practice data isolation needed a real database and real code. We migrated it to Next.js and Supabase while it stayed live for its customers (/work/clinical-stack).
The Bubble version was not a mistake. It was the cheapest way to find out the product was worth building properly, and the migration was the cost of success. If you want the mechanics, the migration guide is at /services/bubble-to-nextjs-migration and the step-by-step is in the migration post.
Build the Bubble app as if you will migrate it
If you choose Bubble, make the eventual move cheaper from day one:
- Name data types and fields the way a database would (no spaces, no duplicates, one meaning per field).
- Put business logic in backend workflows, not scattered across page elements.
- Use option sets for fixed lists; they map directly to enums later.
- Keep a one-page document of the rules the app enforces. That page becomes the test list for the rewrite.
- Avoid storing the same fact in two places "for speed" unless you note it.
Which fits your product?
Tell me three things: what must be true in 90 days, what data you hold and for whom, and who will change the product after launch. I will tell you which way I would go and why. Use the form at /contact, or read about MVP builds at /services/mvp-development and Bubble builds at /services/bubble-development.
