Bubble

Among no-code platforms, Bubble is the one that goes furthest: it doesn't generate brochure sites but complete web applications, with databases, business logic and user management. In return it asks for a real learning curve.

Bubble is a visual development platform for building full-stack web applications without writing code. The editor works on three levels: design, where you compose interfaces by dragging elements onto a page; the database, where you define data types and their fields as you would in a traditional backend; and workflows, where you set the application's logic by defining what happens on each user action. You can handle signup and authentication, data access permissions, payments through integrations such as Stripe, and connect external services with the API connector. A large plugin marketplace extends functionality further. The pricing model is based on Workload Units, units measuring the processing work done by Bubble's servers: every database query, workflow and API call consumes a share, and each plan includes a monthly allocation. This is the most delicate aspect to monitor, because cost grows with actual app usage and not just with user numbers.

For founders, startups and product teams wanting to build an MVP or working SaaS application without hiring developers, accepting the time investment needed to learn the tool.

Bubble's free plan gives full access to the editor with 50,000 Workload Units per month, but doesn't allow publishing your app: it's for prototyping and learning. Web plans start at $29 per month with Starter (175,000 WU), rising to $119 per month with Growth and $349 per month with Team, all billed annually; monthly billing costs around 20% more. Dedicated plans for native mobile apps start at $42 per month and combined web and mobile plans at $59. Exceeding included Workload Units incurs additional charges, so it pays to monitor consumption from the dashboard.
