Bubble agency vs custom code: when to stay and when to move
Short answer: Stay on Bubble with a good Bubble agency when your app works, your workload costs are steady and you mostly need new features. Move to custom code when workload costs keep climbing, you need features Bubble cannot do well, or investors and buyers want code you can export. Bubble does not export source code, so a move means a rebuild. Plan it with your data, users and launch date in mind.
You're on Bubble, costs are climbing or you've hit a wall, and you're trying to work out whether to stay and fix it or move to custom code.
I'm Ranjit, and I run Blur Studio: 15+ years building software, 120 apps taken live, and clients who have gone on to raise $10M+. I build apps, business software, and AI agents and workflows, one project at a time. I also work differently from most of what else is out there, more on that further down this page.
Your app runs on Bubble. It may be live with paying users, or it may be half built. Now you face a choice. You can hire a Bubble agency to keep building on Bubble, or you can move the app to custom code.
This guide helps you make that call. It covers what Bubble costs to run and what workload units are. It also shows when each path makes sense, and how to pick the right team.
What does a Bubble agency do?
A Bubble agency is a team that builds and fixes apps on Bubble, a no-code platform. No-code means you build with visual tools instead of writing code. A good agency can add features, clean up slow workflows, set privacy rules and connect your app to other tools.
Bubble runs its own Experts directory. You can search it for freelancers or agencies, and filter by budget, services, location and language. Bubble also ranks agency partners as Gold, Silver or Bronze. That gives you a starting list, but you still need to check each one yourself.
How much does Bubble cost to run?
Bubble charges a monthly plan fee. Each plan includes a set number of workload units. The prices below come from Bubble's own pricing pages as of October 2026. Prices are in US dollars per month.
| Plan | Web only, billed yearly | Web only, billed monthly | Web and mobile, billed yearly | Workload units each month |
|---|---|---|---|---|
| Free | 0 | 0 | 0 | 50,000 |
| Starter | 32 | 39 | 59 | 175,000 |
| Growth | 119 | 134 | 209 | 250,000 |
| Team | 349 | 399 | 549 | 500,000 |
| Enterprise | Ask Bubble | Ask Bubble | Ask Bubble | Custom |
Bubble also sells mobile only plans. The Growth plan includes 2 app editors and the Team plan includes 5. Prices change, so check Bubble's pricing page before you decide.
What are workload units?
Bubble's manual says workload adds up the server power your app needs to run and grow. Bubble measures that work in workload units, or WU. Page loads, workflows, searches and bulk changes to data all use WU.
If your app uses more WU than your plan includes, you have options. Bubble offers pay as you go overages, charged per extra 1,000 WU. It also sells discounted workload tiers and workload subscriptions. On the Free plan, you cannot turn overages on.
This matters for your choice. A busy app with slow workflows can use far more WU than it needs. A good Bubble agency can often cut that use by fixing the workflows. That is one of the best reasons to hire one.
When should you stay on Bubble with a good agency?
Bubble is a good home for many apps. Stay on it when most of these are true.
- The app works: Users can do what they need, and the bugs are small.
- Your WU bill is steady: Costs grow in line with your users and revenue.
- You need new features: Most of your plans are new screens, reports or links to tools Bubble supports.
- Your team knows Bubble: You or your staff can make small changes in the editor yourselves.
- Speed to market matters most: You want to test new ideas in weeks.
In these cases, a move to custom code costs money and time without a clear gain. Spend that money on a Bubble agency that can tidy up the app and help it grow.
When should you move from Bubble to custom code?
Move when the platform starts to hold your business back. These are the common signs.
- WU costs keep rising faster than revenue: You have already tuned the workflows, and the bill still climbs.
- You need features Bubble does not do well: Examples include heavy data processing, complex real-time features or deep AI work.
- You need to own and export the code: Bubble's support page says, "We do not support on-premise self-hosting or code exports at this time." Some investors, buyers and large customers want code they can inspect and host.
- Speed is a problem you cannot fix: Pages stay slow even after an agency has worked on them.
- You want to hire normal developers: Custom code opens a much larger pool of people who can work on your app.
Bubble vs custom code: how do they compare?
| Question | Bubble with an agency | Custom code |
|---|---|---|
| How fast can you change things? | Very fast for standard features | Fast once set up, slower for the first build |
| Who can make changes? | Bubble developers, or you in the editor | Any developer who knows the code language |
| Can you export the code? | No, only app files for Bubble and data as CSV | Yes, you hold the full code |
| How does cost grow? | Plan fee plus workload units | Hosting and database fees, which you choose |
| Where can it run? | Only on Bubble | On the hosting you pick |
| Best for | Testing ideas, internal tools, steady apps | Apps with heavy use, complex features or a planned sale |
How do you move a Bubble app to custom code?
Bubble does not export source code, so moving means you rebuild the app. Bubble does let you export your app as a file for other Bubble apps, and your data as CSV files. CSV is a simple spreadsheet format. So the data can come with you, but the logic must be rebuilt.
A safe move usually follows these steps.
- Map the app: List every page, workflow, user type and outside service in the Bubble app.
- Keep Bubble running: Your users stay on Bubble while the new app gets built.
- Rebuild in stages: Start with the parts that cost the most WU or cause the most trouble.
- Move the data: Export the data, clean it and load it into the new database. Test it with real records.
- Plan logins: Decide how users will sign in on the new app, for example by asking them to set a new password.
- Switch over on a quiet day: Point your domain at the new app, and keep the Bubble app ready as a backup for a short time.
Your existing Bubble app is a great guide for the rebuild. It shows exactly how every screen should work.
How do you choose a Bubble agency?
Start with Bubble's Experts directory, then check each agency yourself.
- Ask for live apps: Ask for links to Bubble apps they built that have real users.
- Ask about workload: Ask how they would cut your WU use. A good agency will ask to see your app's workload chart.
- Ask about privacy rules: Bubble's privacy rules decide who can see each piece of data. Ask how they set and test them.
- Ask who owns the app: The Bubble account and the app should sit in your company's name.
- Ask about custom code: A good agency will tell you honestly if your app has outgrown Bubble.
Watch out for an agency that pushes you to stay on Bubble no matter what. Also be careful with one that pushes a rebuild before it has looked at your app.
What about FlutterFlow agencies?
FlutterFlow is another visual builder, often used for mobile apps. It differs from Bubble on one key point. FlutterFlow can push your app's code to a GitHub repository that you create in your own account. So with FlutterFlow, you can keep a copy of the code. If code ownership is your main worry, ask a FlutterFlow agency to set this up from day one.
How does Blur Studio approach Bubble apps?
I have built on Bubble for many years, and I also move Bubble apps to custom code. So I do not need to push you one way. I start by looking at your app, your WU bill and your plans for the next year. Then I tell you which path I think fits and why.
If staying makes sense, I clean up the app and help it grow on Bubble. If moving makes sense, I rebuild it in stages while your users stay on Bubble. Either way, the code and every account stay in your name. After launch, I can keep taking care of the app.
If your app started in an AI tool such as Lovable or Bolt, read my guide on making a vibe coded app production ready. If you are still deciding how to build, see AI app builder vs hiring a developer. For the cost side of a rebuild, see my guide to AI app development cost.
Questions people ask
What does a Bubble agency cost?
Agency fees vary with the size of the work and the team. Ask two or three agencies to price the same written list of tasks. Remember to add Bubble's own plan fee and any extra workload units to your monthly budget.
Can I export my Bubble app's code?
No, you cannot. Bubble's support page says it does not support code exports or self-hosting. You can export your app as a file for other Bubble apps, and your data as CSV files.
Is Bubble good enough for a real business?
Yes, for many businesses it is. Bubble works well for apps with steady use and standard features. It fits less well when workload costs keep rising, when you need complex features, or when buyers want code they can inspect.
How do I hire a Bubble developer?
Start with Bubble's Experts directory, which lists freelancers and agencies with Gold, Silver or Bronze partner tiers. Ask each one for live apps, a plan to cut your workload use, and proof that your account stays in your name.
How long does it take to move from Bubble to custom code?
It depends on how many pages, workflows and user types your app has. A small app with a few workflows moves much faster than a large app with many user types. A careful review of the Bubble app gives you a real estimate.
Roughly what does this cost?
As a broad reference, fixes and finishes start at around $1,500, and new builds start higher, always a fixed price agreed in writing before I start, never an hourly rate. My AI app cost guide explains what actually drives a quote up or down.
Is my project too small for this?
No. Most of the owners I work with have no tech team at all, that is the whole point. If the smarter move is a cheap software subscription instead of custom software, I will tell you that on the first call, even though it means I do not get paid.
