Bubble lets you build and launch a web app visually, without writing code, which is exactly why so many MVPs start there. Custom development takes longer up front but removes the ceiling on performance, cost per user, and how far the product can scale. The right call depends on where your product is headed, not just where it is today.
Bubble is a strong way to test whether a product idea has legs before committing real development budget to it. Once you have paying users and real usage data, though, its per-workload pricing and platform lock-in start working against you. Rebuilding in custom code at that point isn't starting over — it's translating a validated product into something that can actually scale and that you fully own.
Usually once the product has validated demand and workload-based pricing or performance limits start constraining growth — at that point, a custom rebuild converts proven traction into an app you fully own and can scale without a platform ceiling.
For a first version, yes — you skip most development cost and get a working app fast. Bubble's workload-based pricing can become expensive as usage grows, which is when custom development typically becomes the more cost-effective path.
The data model and product logic transfer directly since they're already validated — the rebuild is mainly re-implementing the UI and workflows as standard code, which is faster than designing a new product from zero.
The most common ones are workload-based pricing that scales steeply with usage, performance under heavy data or traffic, and vendor lock-in — Bubble apps don't export to standard code, so you're building on their platform long-term.
