What is Bubble?
Bubble is a no-code platform that enables users to build web applications without writing code. Founded in 2012, Bubble bootstrapped for seven years before raising $106.3 million in funding in 2021, and generated $74.2 million in revenue as of 2024. The platform currently hosts over 7.2 million applications.
Bubble's core feature is its visual drag-and-drop editor. Users can arrange UI elements, configure workflows, and build databases without directly writing HTML, CSS, or JavaScript. It provides a full-stack development environment where both frontend and backend can be managed from a single platform.
In June 2025, Bubble launched a native mobile app builder in public beta. This React Native-based feature enables the creation of iOS and Android apps, though it remains in beta with various limitations. A separate pricing structure for mobile app functionality took effect on October 1st.
Key Strengths of Bubble
1. High Degree of Freedom and Customization
Bubble's greatest strength is its flexibility compared to other no-code tools. While competitors like Glide and Adalo rely on predefined layouts and templates, Bubble allows pixel-level freedom in UI element placement. You can implement detailed customizations including workflow configuration, data structure design, and API integrations, enabling complex business logic.
2. Full-Stack Development Environment
Bubble provides integrated frontend and backend on a single platform. It includes a built-in database (relational DB structure), allowing you to create tables and define relationships without separate DB setup. You can also visually construct custom workflows and backend logic, enabling even users with limited development knowledge to implement server-side functionality.
Bubble's marketplace offers thousands of plugins and templates. You can easily integrate various third-party services through plugins: payment systems (Stripe, PayPal), authentication (OAuth, Google Sign-in), maps (Google Maps), charts (Chart.js), and more. This significantly reduces development time and facilitates feature expansion.
4. Rapid Updates and Community Support
Bubble updates quickly and actively incorporates user feedback. It offers abundant learning resources including official forums, tutorials, and templates, with active domestic and international communities facilitating problem-solving and knowledge sharing.
Limitations of Bubble
1. Steeper Learning Curve Than Expected
Despite being "no-code," Bubble's interface is quite complex. While drag-and-drop based, understanding data structure design, workflow configuration, and conditional logic requires basic programming concepts.
Users have described Bubble as "one of the hardest no-code platforms to use." For complete beginners learning independently, it's overwhelming, mastering it requires dozens of hours of learning and practice. Complex workflows or data relationship configurations can produce unexpected errors, requiring debugging skills.
2. Unpredictable Cost Structure (Workload Units)
As of 2025, Bubble operates with the following pricing tiers:
Free Plan: $0 (50,000 WU/month, no live deployment, Bubble branding required)
The issue is the Workload Units (WU) system. WU measures the server workload your app consumes, database queries, workflow executions, API calls all consume WU. If usage exceeds your plan's limit, additional charges ($0.30 per 1,000 WU) apply.
It's extremely difficult to accurately predict WU consumption in advance. A single simple scheduling app consuming 700,000 WU has been documented. As your app becomes more complex or user base grows, WU consumption can increase exponentially, potentially driving monthly costs into hundreds of dollars or more. Cases where development costs exceed expectations when starting with MVP goals are common.
3. Performance Issues and Load Times
As features become more complex, Bubble apps tend to slow down. This is particularly problematic in mobile environments, becoming a major cause of user churn. Compared to fully native apps, response times and performance are inferior, and this problem worsens for data-heavy applications.
According to independent research as of February 2026, Bubble's native mobile builder has load times of 8-14 seconds, significantly degrading user experience in production environments.
4. Not True Native Mobile Apps
Bubble's most critical limitation is being a web app-centric platform. The mobile builder launched in 2025 remains in beta with serious constraints:
No automatic web-to-mobile conversion: Web and mobile are completely separate projects, you must rebuild all screens and workflows from scratch. Only the database is shared.
Performance issues: 8-14 second load times, limited hardware access
Limited native features: Offline sync, biometric authentication, sensor access are limited or unimplemented
Build restrictions: Monthly app build limits (varies by plan)
No code export: Bubble doesn't support source code export, creating high platform dependency
In reality, Bubble is optimized for web apps and PWAs (Progressive Web Apps) rather than mobile apps. If you need true native mobile apps, Bubble isn't the right choice.
5. Team Collaboration Challenges
Bubble's workflows and configurations are so granularly structured that inheriting projects from others is difficult. Implementation approaches vary widely, and without clear conventions like in code, project handoff involves significant learning costs. This becomes a major obstacle in team-based projects.
The Alternative: AppBuildChat for Managed Mobile App Production
AppBuildChat takes a completely different approach from Bubble. While Bubble is a "DIY tool for building yourself," AppBuildChat is a "managed production service where experts build for you."
How Does AppBuildChat Work?
Chat with AI bot: Users describe their desired app through conversation with an AI chatbot.
Automatic PRD generation: AI generates a structured Product Requirements Document (PRD) based on the conversation.
Review app preview: Preview the app for free.
Professional engineers after payment: Upon payment, an actual development team reviews and refines the PRD, then builds a real native mobile app.
App Store launch within 7 days: Delivers production-ready apps launchable on App Store and Google Play within 7 days.
AppBuildChat's Core Differentiators
1. Real Native Mobile Apps
Unlike Bubble's beta mobile builder, AppBuildChat is designed from the ground up for mobile app production.
Creates native apps that can actually be published to iOS and Android app stores.
Not web apps, not PWAs, not wrapper apps.
2. Managed Service, Not DIY
Users don't need to configure workflows or build databases like in Bubble.
Professional engineering teams validate requirements, refine edge cases, and build production-level apps.
Users only need to explain "what they want." The "how to build it" is handled by experts.
3. Predictable Fixed Cost
Unlike Bubble's WU system, AppBuildChat charges a fixed subscription of $299/month.
This includes hosting, backend infrastructure, monitoring, and maintenance.
No risk of cost explosion based on usage.
4. Zero Learning Curve
While Bubble requires dozens of hours of learning, AppBuildChat has nothing for users to learn.
Explain requirements via chat and you're done.
5. 7-Day Launch Guarantee
Building with Bubble yourself can take weeks to months.
AppBuildChat delivers completed apps within 7 days according to the PRD.
Who Should Use AppBuildChat?
AppBuildChat is optimal for:
Founders disappointed by outsourcing quotes: When agency quotes reach $50K~$100K but you want real apps quickly at reasonable prices
Those who've experienced no-code tool limitations: Built prototypes with Bubble or Adalo but realized actual app store publishing is impossible
Those without time to build themselves: Don't want to invest time and effort learning and building with Bubble
Those where production quality matters: Can't tolerate beta features or performance issues, need apps that can be delivered to actual customers

Finding the Right App Development Solution for You
When to Choose Bubble
Bubble is suitable in these situations:
Web application goals: Building web-based services like SaaS, marketplaces, CRMs, dashboards makes Bubble a strong choice.
Prototyping and MVP validation: Useful for quickly testing ideas and getting user feedback with prototypes.
Willingness to learn: If you want to invest time learning the platform and directly control all aspects of your app, Bubble's high freedom is advantageous.
Extremely limited budget: Can start with the free plan initially (though with WU limits and feature constraints).
However, using Bubble to build real native mobile apps is not recommended. Considering beta feature instability, performance issues, and separate project management burden, other alternatives (FlutterFlow, Adalo, etc.) or managed services are more realistic.
When to Choose AppBuildChat
AppBuildChat is optimal in these situations:
Actual app store launch is the goal: Need native mobile apps to actually launch on App Store and Google Play
Agency quotes are burdensome: Received $50K-$100K quotes but want faster, cheaper alternatives
No time/capability to build yourself: Business owners, founders without time and technical skills to learn and develop with Bubble
Production quality matters: Need stable apps deliverable to actual customers, not beta features or experiments
Prefer predictable costs: Want to manage with fixed fees without unexpected cost explosions like WU overages
AppBuildChat's limitation is restricted app complexity. The backend consists of standard features like authentication, database, storage, and push notifications, with no support for complex custom logic or non-whitelisted third-party integrations. However, most mobile apps (booking apps, community apps, payment apps, etc.) can be sufficiently implemented within this scope.
Conclusion: Build It Yourself vs Delegate It
Ultimately, the choice is "Will you learn and build yourself, or delegate to experts?"
Learning Bubble is a valuable investment for those who want to build long-term development capabilities. But focus on web apps.
AppBuildChat is suitable for those who want to quickly launch production-level mobile apps to market. Instead of building yourself, focus on clearly communicating "what" you want.
If you're considering mobile app development with Bubble, we recommend trying AppBuildChat first. Generating a PRD through conversation with the AI chatbot and checking the app preview is free, allowing you to judge how well the managed service fits your needs.
