What Bubble does well
Bubble is the most powerful no-code application builder on the market. Unlike Wix or Webflow, Bubble is designed specifically for applications — not marketing websites. It supports relational-style data models, user authentication with privacy rules, multi-step workflows, and dynamic page rendering based on database state.
For a founder who needs to test an idea without a developer, or for a team that needs an internal tool in days rather than months, Bubble can genuinely deliver. The visual workflow editor handles logic that would otherwise require a developer to implement. The data editor supports basic relational concepts.
For prototyping and early-stage product validation, Bubble has a real use case. This is honest and worth saying clearly before the rest of this comparison.
The three limits that matter for a production business app
Bubble works well at prototype scale. The constraints that do not matter at prototype scale become significant once an application is in production and carrying real business data.
Limit one: your data is on Bubble's servers
Every record created in a Bubble app lives in Bubble's database on Bubble's infrastructure. You access it through Bubble's data editor and Bubble's API. You cannot run direct SQL queries. You cannot join Bubble data to an external system at the database level. You cannot write a migration script that modifies the underlying schema.
If you want to move your application off Bubble, you get a data export in CSV or JSON. You do not get the application. You do not get the code. You do not get a schema you can migrate. The application logic is locked in Bubble's proprietary visual runtime. The data is the only thing you can take with you, and only in flat formats.
This is not a hypothetical risk. Bubble has changed pricing multiple times. The free tier has been modified. Existing apps on deprecated plan tiers have been required to upgrade. Every business running a production application on Bubble carries the risk that Bubble's terms change faster than their migration capacity.
Limit two: performance has a ceiling
Bubble apps run on Bubble's infrastructure in an interpreted, non-compiled environment. The visual logic is translated at runtime into backend operations. As workflow complexity increases and data volumes grow, this interpretation layer adds latency that does not exist in directly compiled or natively executed code.
Bubble's own documentation and community forums are explicit about this: complex workflows on large datasets cause performance issues that are difficult to resolve without architectural changes inside Bubble's environment. The ceiling is real and it is lower than the ceiling on dedicated server infrastructure.
A WordPress-based application running PHP on dedicated hosting has a different scaling profile. Performance bottlenecks are addressed by tuning the server, the database queries, and the PHP code — all of which are standard, solvable infrastructure problems.
Limit three: the monthly cost never ends
Bubble is subscription-based. A production app with meaningful usage runs at A$50 to A$500+ per month depending on the plan tier. That cost continues indefinitely. There is no "own it outright" option.
| Scenario | Year 1 | Year 3 | Year 5 |
|---|---|---|---|
| Bubble (A$150/month) | A$1,800 | A$5,400 | A$9,000 |
| Merebase on WordPress | A$499 + A$180 hosting | A$499 + A$540 hosting | A$499 + A$900 hosting |
The Merebase app is a one-time build cost. Hosting for a basic WordPress install runs A$5 to A$20 a month — often already paid for an existing site. The ongoing costs are the same hosting the business already pays. Nothing else.
What WordPress provides that Bubble does not
- Data on Bubble's servers
- No direct SQL access
- Proprietary runtime — can't export the app
- Performance ceiling on complex workflows
- Monthly subscription A$50 to A$500+
- Bubble controls pricing and platform terms
- No code ownership — logic stays in Bubble's editor
- Migration path is a CSV export only
- Data in MySQL on your server
- Full SQL access, direct database control
- GPL code delivered to you, runs anywhere
- Performance scales with server capacity
- Hosting A$5 to A$20/month — one-time app cost
- No vendor control — open source, no kill switch
- Code ownership complete — modify anything
- Migration path is standard PHP and MySQL
When Bubble is the right answer
Bubble makes sense when speed of validation is more important than cost, performance, and ownership. Building a prototype in two weeks on Bubble to test an idea is a reasonable trade-off. Paying A$150 a month for a year while validating is much cheaper than paying a developer for the same period.
Bubble is the right tool for testing an idea. WordPress is the right platform for running a business on it.
The transition point is when the application moves from experiment to production. Once real business data is in it. Once staff depend on it daily. Once the cost of migration matters. Once the monthly cost is simply a permanent overhead with no end date.
That is when ownership matters. That is when running on infrastructure you control — with code you own and data in your database — is not a preference. It is a structural difference in risk.
A Merebase rebuild takes the core requirements from your Bubble app and delivers them as a WordPress plugin on infrastructure you own. Your data migrates from Bubble's CSV export into your MySQL database. The application logic is rewritten in PHP. You end the subscription and move to hosting costs that likely cost less per year than two months of your current Bubble plan.
The migration is not trivial. But the comparison over three or five years is not close.
