Choose Lovable when you want to own a React codebase built fast with AI. Choose Bubble when you want no code involvement at all and a visual editor with the backend built in. Choose custom code when the product is already at known scale, the hard part is engineering, or you can see a platform ceiling within two years. All three can get a first web app live in weeks. The real question is what you are holding at the end and who maintains it.
The one-line difference
- Bubble is a full no-code platform. Editor, database and hosting in one place. You will never open a code file. The trade is a firmer ceiling and costs that grow with usage.
- Lovable is AI-assisted code. It generates a React and Supabase app from prompts, fast, but reaching production means working in that code. The payoff is a standard codebase you own with no platform pricing tied to traffic.
- Custom code is a developer building from scratch in a general stack. Slowest and most expensive up front, no ceiling, cleanest asset.
Cost
Both Lovable and Bubble builds start around $1,499 with an agency, and their subscriptions are in the same range, roughly $25 to $32 a month to begin. The differences show up later:
- Bubble adds cost as workload grows, through higher plan tiers. Predictable, but it climbs.
- Lovable shifts some cost into developer time, because the generated code needs hardening for production. Once that is done, running costs are just Supabase and a host, both cheap at small scale.
- Custom code is a larger build bill and lower running costs, with a developer needed for changes.
Scale and ceiling
Bubble runs real products with thousands of users comfortably. Its ceiling is very heavy concurrent load, queries over millions of rows, and complex real-time systems.
A Lovable app is standard React and Supabase, so a team can optimise it like any codebase and there is no pricing penalty for growth. It scales more like custom code because, underneath, it is custom code.
If you already know you are heading for genuine scale, custom from the start avoids a migration under pressure.
Who maintains it
This is often the deciding factor.
- If you will maintain it and you do not write code, Bubble is the honest choice. Lovable will frustrate you the first time a prompt breaks something.
- If a developer will maintain it, Lovable gives them a normal codebase to work in, which most engineers prefer to a proprietary platform.
- If you have no one to maintain it yet and the app is simple, Bubble keeps you self-sufficient longest.
A simple way to decide
Answer these:
- Do you want to own a code repository? If yes, lean Lovable. If no, lean Bubble.
- Who changes the app after launch: you, or a developer?
- Is year-three scale genuinely heavy, or normal?
- Are you raising money on the technology itself?
If you want a repo and have a developer, Lovable. If you want to stay in a visual tool, Bubble. If scale is heavy or the tech is the pitch, custom code.
What we do
At MarkLogix we build on all three and recommend one after scoping, not by default. Most first products go to Lovable or Bubble, priced about $500 below the going agency rate, with the data and code kept portable so the door to custom stays open. Tell us what you are building and you will get a written recommendation and an indicative price, not a sales call.
