Bubble review

Bubble is a hosted no-code app-building platform, not a code library, CLI or self-hosted server. You build in its visual editor, where the UI, database and backend workflows are configured without writing code. Its AI Agent can turn an idea into an editable app, but the resulting app remains inside Bubble’s platform rather than becoming a conventional source-code project.

The platform targets teams that want to build and operate an app without separately assembling a frontend framework, backend, database and hosting provider. Bubble says a web app can share data and workflows with native iOS and Android apps, and that hosting, security and infrastructure are included as the app grows. It also supports direct submission to the App Store and Google Play Store. That puts Bubble across several parts of a typical stack: app design, application logic, data, deployment and hosting. The trade-off is that those parts are managed through Bubble’s hosted environment.

Bubble’s main development surface is its AI Agent and visual editor, rather than a code-first API workflow. The vendor describes editing workflows, database structure and design in the editor, and says the Agent can set up connections to tools such as LLMs and payment providers. The homepage also names Marketplace plugins and a Bubble MCP integration for connecting an external agent such as Claude or Codex; MCP is marked beta.

Bubble’s homepage does not name a programming language, SDK or CLI. It also does not identify a specific API protocol or webhook surface there. Before committing to a language-based integration, confirm SDK and API support in Bubble’s technical guides and documentation. The homepage links to those guides, along with its Academy, forum, plugins and templates. The integration model to assess is therefore the visual editor, Agent-assisted connections, plugins and beta MCP—not a documented language-specific SDK stack. Verify which connections cover your authentication, error handling and deployment needs.

Bubble has a free plan for development and testing: one app editor, 50,000 workload units (WU) per month, 0.5 GB of file storage and six hours of server logs. It is dev-only, with no custom domain or live deployment. The listed web-app plans start at Starter for $32 month to month or $29 per month billed annually. Starter includes 175,000 live WU and 100,000 dev WU per month.

Growth is $134 monthly or $119 billed annually, with two editors and 250,000 live WU. Team is $399 monthly or $349 billed annually, with five editors and 500,000 live WU. Both include 100,000 dev WU. Workload overages can add to the bill: the listed pay-as-you-go rate is $0.30 per 1,000 WU; Workload Tier 1 adds 200,000 WU per month for $29 monthly or $26 billed annually, and lowers overage to $0.15 per 1,000 WU. Enterprise pricing is custom. The listed 14-day Starter trial requires a payment method and a $1 hold.

Bubble is a hosted, proprietary platform, not an open-source project or a self-hosted server. The vendor’s homepage describes its own hosting and infrastructure; it does not present a self-hosting deployment option. Teams should confirm data export formats and scope with Bubble before committing, because export details are not published on the vendor's site.

The main migration concern is the app itself: its visual design, workflows and data model are built inside Bubble’s environment, rather than maintained as portable application source code. Reddit developers describe lock-in as a concern and discuss rebuilding or moving separate backend and frontend components to other services. Those reports are individual experiences, not a supported migration path. Before a production launch, ask Bubble what data and files can be exported, in what formats, and whether workflows or app logic can be transferred. Budget for a rebuild if portability is a hard requirement.

Bubble says its platform includes hosting, infrastructure and built-in privacy rules, and that it runs on a SOC 2 Type II compliant platform. The listed plans differ in workload units, server-log retention and features such as branches, editor seats and two-factor authentication. Check those limits against your expected traffic, data access patterns and incident-response needs; Enterprise lists dedicated hosting and a choice of data location.

The vendor material does not publish a reliability SLA or a general request-rate limit. Reddit developers report workload costs becoming a concern as apps grow, and some describe latency or performance problems. Other commenters say Bubble works well for specific apps and value its plugin marketplace. Treat those as user reports, not a guarantee of what your app will experience. Model WU consumption before launch, monitor usage and confirm support, backup and data-export terms with Bubble. Apps with strict latency, portability or infrastructure-control requirements should validate those constraints early.
