Bubble vs Custom Software: The Stage-Appropriate Choice

The right tool depends on where you are. Here's how to know when Bubble is enough — and when it's time for custom.

This comparison isn't about which is "better." Bubble and custom software serve different stages of a company's lifecycle. The goal is to help you identify which stage you're in and act accordingly.

We recommend Bubble to pre-PMF startups all the time. We also rebuild Bubble apps for post-PMF startups regularly. Both recommendations are honest.

When Bubble Is the Right Call

Bubble excels in a specific and valuable stage of company growth. Don't skip it if you're in this stage.

Pre-Product-Market Fit

You're still figuring out what to build. Speed of iteration matters more than performance or scale.

Non-Technical Founder

You can build and iterate without a developer. That independence is worth the trade-offs.

Budget Under $25K

If you can't afford custom development, Bubble lets you build something real for $50-350/month.

Internal Tools Only

If only your team uses it and you have under 50 users, Bubble's limitations rarely matter.

When Custom Software Becomes Necessary

There's usually a clear inflection point. You'll know it when you hit it.

🔶

Post-PMF Scaling

You've proven the model and need to scale users, features, and performance simultaneously.

🔶

Raising Series A+

Investors will ask about tech stack. "Bubble" isn't the answer they're looking for.

🔶

Performance-Sensitive Product

Slow pages lose users. If speed matters to your conversion rate, Bubble is a liability.

🔶

SEO-Dependent Growth

Organic search requires fast, properly-rendered pages. Bubble's client-side rendering hurts rankings.

The True Cost Comparison

Year 1: Bubble wins on cost. You can run a production MVP for under $5,000/year. Custom development costs $25,000-60,000 upfront.

Year 2: Costs converge. Bubble's usage-based pricing grows as your app scales. You might be spending $6,000-15,000/year on Bubble. Custom software hosting stays at $1,200-3,600/year.

Year 3+: Custom software wins decisively. You own the asset. No per-user fees, no WU charges, no surprise pricing changes. The Bubble bill just keeps growing.

The Hidden Cost: Opportunity Cost

The biggest cost of staying on Bubble too long isn't the monthly bill — it's the features you can't build, the performance improvements you can't make, and the integrations you can't implement because the platform won't let you.

Every month you spend working around Bubble's limitations is a month you're not building the product your users actually need. That opportunity cost compounds.

The Decision Framework

Ask yourself three questions: (1) Have I found product-market fit? If no, stay on Bubble. (2) Am I losing users or revenue due to platform limitations? If yes, rebuild. (3) Can I afford $25K+ for custom development? If no, keep optimizing Bubble until you can.

If you answered yes to all three, the decision is clear. The longer you wait, the more expensive the eventual migration becomes — because you'll keep building more in Bubble that needs to be rebuilt.

Frequently Asked Questions

Should I start with Bubble or custom?
If you're pre-product-market fit and non-technical, start with Bubble. It's the fastest way to validate an idea. If you already have a technical co-founder and funding, you might skip Bubble and build custom from day one.
When exactly should I switch from Bubble to custom?
When you've confirmed product-market fit AND (performance is losing you users OR investor due diligence requires a real tech stack OR your monthly Bubble costs exceed $500/month). Any one of these is sufficient reason.
Is it wasteful to build in Bubble then rebuild?
No. Think of Bubble as a prototyping tool. The $5,000-10,000 you spent on Bubble saved you from spending $30,000+ on custom development for an idea that might not have worked. That's a smart investment.
Can I use Bubble for some things and custom for others?
Yes. Some teams keep non-critical internal tools in Bubble while rebuilding the customer-facing product as custom software. Use the right tool for each job.
