Bubble

Bubble is a full-stack no-code platform for building, designing, launching and hosting web applications without writing code. It differs fundamentally from website builders, which produce pages, and from form or database tools, which handle one slice of an application. Bubble provides the whole stack: a visual editor for designing responsive interfaces, a database for storing and relating data, a logic layer for defining what happens when users interact with the application, user authentication and permissions, and hosting on managed infrastructure. What emerges is a genuine web application with accounts, persistent data, business rules and integrations — the sort of thing that would otherwise require a developer and several months.

The visual editor places and styles elements directly on a canvas, with responsive rules controlling behaviour across screen sizes. The database is defined through data types and fields with relationships between them, and privacy rules restrict at the record level which users can see or modify what — essential for any multi-user application. Logic is expressed as workflows: a trigger such as a button click or a page load initiates a sequence of actions including creating and modifying records, sending emails, making payments, calling external APIs or navigating elsewhere, with conditions determining which branch executes. An API connector consumes external services, and Bubble applications can expose their own API for other systems to call. A large plugin marketplace adds capability from payment processing and mapping to charting and file handling, and agencies and template authors sell ready-made applications as starting points. Version control, development and live environments, and one-click deployment support disciplined release practice. The platform is used by founders building and validating products, internal teams replacing spreadsheet-based processes, and agencies delivering client work quickly. A free version allows building and learning, with paid plans from around USD 32 per month unlocking custom domains, greater capacity and collaboration, and a free trial available.
