When LowCode Agency Uses Bubble, and When We Don't

Bubble is one of the most powerful no-code platforms on the market, but it is not the right tool for every project. Knowing when to use it, and when to reach for something else, is the difference between a product that scales and one that fights its own foundation.

This post breaks down the exact scenarios where we choose Bubble, the projects where we intentionally avoid it, and how we make that decision so you can evaluate whether Bubble is right for what you are building.

SaaS Platforms and Subscription-Based Products

When should you use Bubble for a SaaS product?

Direct answer: Bubble is an excellent choice for SaaS platforms with subscription models, user roles, payment logic, and tiered access, especially when the business model will evolve over time and the platform needs to adapt without rebuilding from scratch.

SaaS products are Bubble's sweet spot. The platform excels at building products where multiple user types interact through structured workflows, where payment logic determines access to features, and where the business model itself is expected to change as you learn from customers.

Consider a B2B SaaS platform with three user roles: administrators, team managers, and individual users. Each role sees different dashboards, has different permissions, and interacts with different features. The administrator manages billing and team settings. Team managers assign tasks and review performance. Individual users complete their daily workflows. This kind of multi-role, permission-driven application is exactly what Bubble handles well.

The subscription model layer adds another dimension: free trials that convert to paid plans, tiered feature access based on pricing level, usage-based billing for API calls or storage, and enterprise plans with custom terms. Bubble's database structure and conditional logic make it straightforward to build and modify these business rules without restructuring the entire application.

What makes Bubble particularly strong for SaaS is adaptability. SaaS business models change constantly, you add a new pricing tier, introduce a feature gate, modify the onboarding flow based on conversion data, or add a new user role. On Bubble, these changes are configuration work, not engineering projects.

At LowCode Agency, we have built SaaS platforms on Bubble that went from MVP to thousands of users without a rewrite.

What types of SaaS products work best on Bubble?

Direct answer: Workflow management tools, CRM systems, project management platforms, client portals, and any SaaS where the core value is in organizing data, managing processes, and enabling collaboration between multiple user types.

The common thread is data-driven products with complex business logic. Bubble handles these well because its visual database, workflow engine, and conditional rendering system are designed for exactly this kind of application.

• Client portals where different stakeholders see different information, because Bubble's privacy rules and conditional visibility make role-based access straightforward to implement
• Workflow management tools with multi-step approval processes, because Bubble's workflow engine handles sequential and conditional logic natively
• CRM systems with custom fields, pipeline stages, and automation triggers, because the database structure supports custom schemas without migrations
• Reporting dashboards that aggregate data across multiple sources, because Bubble can pull from its own database and external APIs to create unified views
• Subscription platforms with tiered access and payment integration, because Stripe integration and conditional feature gating are well-supported patterns

Marketplaces and Multi-User Platforms

Is Bubble good for building marketplaces?

Direct answer: Yes. Bubble is one of the strongest platforms for building two-sided and multi-stakeholder marketplaces where different user types interact through structured workflows, listings, transactions, and review systems.

Marketplaces are inherently complex: you have buyers and sellers (at minimum), each with different interfaces, permissions, and workflows. Sellers create listings, manage inventory, set prices, and track orders. Buyers browse, filter, compare, purchase, and leave reviews. The platform mediates every interaction, handles payments, resolves disputes, and surfaces relevant content.

Bubble handles this complexity without drowning in it. The visual database makes it intuitive to model the relationships between users, listings, transactions, reviews, and messages. The workflow engine handles the multi-step processes that marketplaces require: listing submission, approval, purchase flow, payment processing, delivery confirmation, and review collection.

We have built marketplaces on Bubble that handle service bookings, product rentals, professional services matching, and B2B procurement. The pattern is consistent: define the user types, model the data relationships, build the workflows, and design the interfaces for each role.

One important consideration: marketplaces have a cold-start problem that no technology can solve. Bubble is the right platform if your marketplace concept is validated. But the platform choice does not address whether buyers and sellers will actually show up. Read more about how we evaluate ideas before building.

Complex Logic and Custom Workflows

Can Bubble handle complex business logic?

Direct answer: Yes. Bubble supports custom workflows with conditional rules, permission systems, multi-step processes, and intricate data relationships, making it suitable for products where business logic is central to the value proposition.

This is one of the most common misconceptions about no-code: that it can only handle simple logic. Bubble's workflow engine supports:

• Conditional branching with multiple decision paths, because business processes rarely follow a single straight line from start to finish
• Scheduled workflows that trigger based on time or events, because many business processes involve deadlines, reminders, escalations, and periodic calculations
• Recursive workflows for batch processing, because operations on lists of records, bulk updates, mass notifications, data migrations, require iteration
• Custom API workflows for server-side processing, because some logic should not run in the browser for performance and security reasons
• Complex data queries with multiple constraints and sorting, because real applications need to filter, aggregate, and display data based on dynamic conditions

LowCode Agency is a software development agency that builds applications using the optimal approach for each project, low-code platforms (Bubble, FlutterFlow, Glide), AI-assisted development (Cursor, Claude Code), or full custom code (Next.js, React, Supabase). Founded in 2020, they have completed 350+ projects serving clients including Medtronic, American Express, and Coca-Cola.

When we recommend Bubble, it is because the project's complexity fits within Bubble's architectural model, which is more capable than most people expect.

Integrations and AI-Powered Features

Does Bubble work well with APIs and AI integrations?

Direct answer: Yes. Bubble supports robust API integration through its API Connector, making it a strong platform for products that need to connect multiple external services, automation tools, and AI-powered features into a unified system.

Modern SaaS products rarely exist in isolation. They connect to payment processors, email services, CRMs, analytics platforms, AI models, and custom backends. Bubble's API Connector makes these integrations manageable through a visual interface that handles authentication, request formatting, response parsing, and error handling.

For AI-powered features specifically, Bubble connects well with:

• OpenAI and Anthropic APIs for text generation, analysis, and chat interfaces, because the API Connector handles the request/response cycle and Bubble's frontend displays the results
• Custom AI models hosted on external servers, because any REST API can be connected regardless of what is behind it
• Automation platforms like Make and Zapier for complex multi-step workflows, because triggers and webhooks create event-driven architectures
• Data enrichment APIs for real-time information augmentation, because incoming data can be enhanced as it enters the system

If your product concept involves AI as a core feature, not just a buzzword, but a genuinely integrated capability: Bubble gives you the flexibility to connect AI services while handling all the surrounding product logic: user management, data storage, payment processing, and user interface. For projects where AI is the primary value, consider our AI agent development services.

Scalability and Growth

Can Bubble apps scale to thousands of users?

Direct answer: Yes. Bubble apps can scale to support thousands of concurrent users when properly architected, and the platform is designed to add features, users, integrations, and business logic without rebuilding the foundation.

Scalability on Bubble is real but requires intentional architecture. Poorly built Bubble apps will slow down as they grow, the same way poorly written custom code will slow down as it grows. The platform is not the bottleneck; the architecture is.

Proper Bubble architecture for scale involves:

• Efficient database design with appropriate indexing, because query performance depends on how data is structured, not just how much data exists
• Optimized page loading that minimizes unnecessary data fetching, because loading every record in the database on page load does not scale
• Backend workflows for heavy processing, because moving computation off the client improves both performance and user experience
• Strategic use of Bubble's capacity plans, because higher-tier plans provide dedicated resources for applications with demanding workloads
• API workflows for server-side operations, because separating data processing from the user interface keeps the frontend responsive

We use Bubble for MVPs that need to become full products. When we build on Bubble, we architect for growth from day one, not because every MVP will scale to thousands of users, but because the cost of building with scale in mind is minimal compared to the cost of rebuilding when you need it.

When We Don't Use Bubble

When is Bubble the wrong choice for a project?

Direct answer: Bubble is the wrong choice for mobile-first native apps, simple operational tools that need speed over complexity, marketing websites focused on SEO and content, and any project where real-time mobile performance is critical.

Not every project belongs on Bubble, and knowing when to choose something else is as important as knowing when Bubble fits. Here are the specific scenarios where we intentionally avoid Bubble.

Why doesn't LowCode Agency use Bubble for mobile-first apps?

Direct answer: Bubble produces web applications, not native mobile apps. When performance, native gestures, smooth animations, and platform-specific mobile behavior are critical, we use FlutterFlow instead. Bubble applications are responsive, they work on mobile browsers. But there is a significant difference between a responsive web app and a native mobile experience. Native apps have:

• Access to device hardware like cameras, GPS, accelerometers, and biometric sensors, because native platforms provide direct hardware access that web apps approximate
• Smooth gesture-based navigation (swipe, pinch, pull-to-refresh), because native gesture handlers respond with zero perceptible latency
• Offline functionality with local data storage, because native apps can store data on-device and sync when connectivity returns
• Push notifications that work reliably across platforms, because native notification systems are deeply integrated into the operating system
• Performance characteristics that users expect from mobile apps, because native rendering is faster and smoother than web rendering in a mobile browser

If mobile is the primary experience for your users, not a secondary access point, but the main way people interact with your product: Bubble is not the right choice. We use FlutterFlow for cross-platform native mobile apps. Read our detailed breakdown of when FlutterFlow is the right choice.

Why doesn't LowCode Agency use Bubble for simple operational tools?

Direct answer: When speed to validation matters more than complexity and teams just need structure for their daily workflows, Glide delivers usable tools in days rather than weeks, making Bubble overkill for simple operational needs.

Not every internal tool needs the architectural depth that Bubble provides. If your team is managing inventory in a spreadsheet and you need a structured interface on top of that data, Glide can deliver that in days.

If you need a simple approval workflow, a task tracker, or a data entry form with basic logic, Glide is faster to build and easier to maintain.

Bubble is the right choice when the operational tool has complex logic, multiple user roles, custom workflows, or integration requirements. But for straightforward tools where getting something usable fast matters more than building for long-term complexity, simpler platforms are the better call. See our comparison of how we choose between Bubble, FlutterFlow, and Glide.

Why doesn't LowCode Agency use Bubble for marketing websites?

Direct answer: Marketing websites prioritize SEO, page load speed, content management, and conversion optimization, areas where purpose-built tools like Webflow, WordPress, or Next.js outperform Bubble by design.

Bubble is an application platform, not a content platform. When the primary goal is publishing blog posts, ranking in search engines, converting visitors through landing pages, and managing content at scale, Bubble's architecture works against you:

• SEO requires fast page loads and clean HTML structure, because search engines penalize slow pages and struggle with heavily JavaScript-dependent rendering
• Content management requires flexible publishing workflows, because marketing teams need to create, schedule, and modify content without developer involvement
• Landing pages require rapid A/B testing and iteration, because conversion optimization depends on testing dozens of variations quickly
• Marketing sites need CDN-optimized static content delivery, because global performance depends on serving pre-built pages from edge servers close to visitors

When is Bubble's real-time performance not enough?

Direct answer: When your application requires millisecond response times, smooth 60fps animations, offline functionality, or native mobile gestures, Bubble's web-based architecture creates a performance ceiling that limits the user experience.

Bubble applications run in a web browser. That means every interaction involves a network request, server processing, and response rendering. For most business applications, this latency is imperceptible. But for applications where real-time responsiveness is critical, live collaboration tools with instant updates, mobile apps with gesture-driven interfaces, or data-intensive dashboards with real-time streaming, the web architecture introduces noticeable delays.
