“Build exactly what you envision with AI + no-code development.”
Bubble is a no-code platform for building web and mobile apps with visual logic, a database, workflows, API integrations, and now also AI-powered app generation.
The tool is aimed at makers, startups, agencies, and companies that want to build and operate applications without traditional full-stack development. In doing so, Bubble covers development, deployment, hosting, and scaling within its own platform ecosystem.

Build exactly what you envision with AI + no-code development
Location: USA ⓘ Bubble Group, Inc., 22 W 21st Street, 2nd Floor, New York, NY 10010, USA.
Growth For growing apps with more workload, more editor/branching options, and advanced production features.
Team For scaling teams with sub-apps, multiple app editors, more branches, more workload, and longer server logs. Other Enterprise Custom workload, choice of hosting location, customizable server, dedicated support, and individual app/mobile limits.
Add-ons Workload tiers, additional file storage, and plugin subscriptions.
Target audience
Bubble is aimed primarily at founders, product teams, freelancers, agencies, and SMEs that want to build web or mobile apps without a traditional software development team. For companies with stricter governance and security requirements, Bubble also offers Enterprise features such as dedicated instances, centralized control, and choice of hosting location. Bubble is especially attractive for teams that want to quickly develop MVPs, customer portals, marketplaces, internal tools, or SaaS products.
Outstanding features
Its strongest features include the visual app builder, integrated database and workflow logic, API integration via the API Connector, as well as hosting and deployment from a single source. Bubble also positions itself with AI-powered app generation, which according to the provider can produce an initial MVP in minutes. For larger organizations, dedicated AWS-based instances, SOC 2 Type II, and advanced security and administration options are relevant.
Key use cases
Bubble is particularly suitable for no-code app building, customer portals, marketplaces, platform products, internal business tools, web apps with forms and workflows, as well as applications with external API integration. Thanks to versioning, team features, and production-ready hosting, the platform can be used not only for prototyping but also for ongoing operations.
Usage & notes
Operation is primarily visual in the Bubble editor. For simple to medium-complexity use cases, no traditional coding is required; however, more complex integrations, data models, and performance issues still require technical understanding. For privacy-sensitive projects, it should be checked early on whether the Bubble DPA, the transfer mechanisms, and the limitations for sensitive data are compatible with your own use case.
| Target audience | Assessment |
|---|---|
| Private individuals / Makers | Suitable – for app ideas, simple web apps, and prototypes without traditional programming. |
| Self-employed / Freelancers | Very suitable – for MVPs, customer portals, internal tools, marketplaces, and web app prototypes. |
| Startups / Founders | Very suitable – Bubble is strong for fast MVPs, SaaS prototypes, and production-oriented no-code web apps. |
| SMEs | Suitable to very suitable – for internal database apps, automations, and customer-facing portals. |
| Large enterprises | Conditionally suitable to suitable – more usable with Enterprise thanks to Dedicated AWS Instance, choice of hosting region, SSO, and dedicated support. |
| Developers | Conditionally suitable – good for rapid implementation, but less suitable for deeply controlled custom architecture. |
Hosting & Data
1) On-prem / local hosting
Meaning: The company operates the solution on its own hardware or within its own infrastructure. In the strictest sense, not only the application runs locally, but ideally the model as well.
2) Private cloud / data center
Meaning: The solution runs in a dedicated or more clearly separated cloud environment, often with a hosting provider or hyperscaler, but in a German data center or in a particularly controlled environment.
3) EU SaaS / managed
Meaning: The provider operates the solution itself as a service. The company uses the tool as a ready-made cloud service, ideally with EU data residency.
4) Hybrid
Meaning: One part of the processing remains internal / local / in a private cloud, while another part runs in an external cloud or EU SaaS.
5) AVV / DPA
Meaning: This is the data processing agreement or Data Processing Addendum. It governs that the provider processes personal data on behalf of the customer and is bound by the customer's instructions.
6) No training
Meaning: The provider does not use your prompts, uploads, attachments, chat histories, or outputs for training or improving the general model — ideally excluded by contract.
7) Open-source / transparency path
Meaning: There is a path toward greater technical transparency and sovereignty, for example through:
- open models
- documented components
- self-hostable parts
- traceable architecture
- export / switching options

On-prem / local hosting: indirect / not available
Bubble describes the platform as a cloud-based deployment in which apps are hosted on Bubble’s cloud infrastructure; the website does not mention an on-premises/local or self-hosted deployment.
Private Cloud / Data Center: Partially
The Enterprise page mentions “Choice of hosting region” and states that the application can be hosted on an isolated server in a specific AWS data center region. This suggests a more isolated environment, but specific EU/EEA regions or details regarding a dedicated private cloud are not provided on the pages found.
EU SaaS / Managed: Partially
Bubble operates the solution itself as SaaS/PaaS on AWS. EU/EEA-compliant use may be possible based on the hosting region selection for Enterprise, but the website does not clearly guarantee general EU data residency for the Managed service.
Hybrid: Indirect / Not Available
A hybrid model involving processing that remains internal/on-premises and external Bubble operations is not described on the website.
DPA: Covered
Bubble publishes a DPA/AVV and states in its Terms that the DPA applies. The DPA specifies that Bubble generally processes customer data only at the customer’s direction or for the purpose of providing services.
No training: indirect / not available
The Terms explicitly state that Bubble may use the input and output of the “Bubble AI Tools” for training, refinement, and further development. A clear opt-out for AI training or a general contractual exclusion is not specified on the pages found.
Open Source / Transparency Path: Indirect / Not Available
Open-source components, open models, or self-hostable parts are not specified on the pages found. A certain level of transparency exists only indirectly through the DPA, the list of subprocessors, and documented security/hosting specifications.
Data Processing
The website confirms that Bubble operates applications in its own cloud infrastructure on AWS. Bubble publishes a DPA/AVV, lists subprocessors, and describes transfer mechanisms for EU/EEA data. For Enterprise, the website describes the option to select a hosting region on an isolated server within a specific AWS data center region. However, the pages found do not document a general standard requiring that data remain exclusively within the EU/EEA. For AI features, it is also documented that input and output data may be used to further develop the Bubble AI tools.
Conclusion
From a hosting and data protection perspective, Bubble is not documented as being unequivocally and fully GDPR-compliant in its standard SaaS offering for an EU/EEA directory, but it can be used under certain conditions: specifically with a DPA/AVV, careful review of the AI features used, and—if available in the subscribed setup—a suitable AWS region for hosting. Because EU data residency is not generally clearly documented and AI training for Bubble AI tools cannot be ruled out, the overall rating is “conditional.”

GDPR-compliant usage possible?
Bubble documents several components relevant to GDPR compliance for the EU/EEA region: a privacy policy, a DPA/AVV, subprocessors, data transfer mechanisms for EU/EEA data, and a choice of hosting regions for isolated servers. At the same time, Bubble is a U.S.-based provider; its standard platform is cloud-based on AWS; the website does not specify a clear, general EU data residency standard for all pricing plans; and regarding the AI features, the Terms reserve the right to to use input and output for training and further developing the Bubble AI tools. Therefore, GDPR-compliant use in the EU/EEA appears plausible only under certain conditions, particularly with a sound contractual setup, an appropriate hosting region, and cautious or limited use of the AI features.
Positive
Positively noted are the company’s own DPA/AVV, the inclusion of SCCs or Data Privacy Framework mechanisms for EU/EEA-related transfers, a published list of subprocessors with update and opt-out mechanisms, as well as security certifications such as SOC 2 Type II at the Bubble level and AWS as the underlying infrastructure with ISO/IEC 27001 and SOC 2 compliance. For Enterprise, the option to select a specific AWS data center region for isolated servers is also mentioned.
Negative
A negative or limiting factor is that Bubble operates as a U.S. provider, and the website does not provide general evidence that customer data is stored or processed exclusively within the EU/EEA by default. Furthermore, the Terms explicitly state that Bubble may use input and output from the “Bubble AI Tools” for training, refinement, and further development; a clear, product-specific opt-out for AI training is not specified on the website. On-premises/self-hosting is also not described.
Server Location
Bubble lists AWS as its hosting infrastructure on the website. A specific standard server location for all customers is not specified on the website. For Enterprise, it is stated that applications can be hosted on an isolated server in a specific AWS data center region; however, the pages reviewed do not specify whether and which specific EU/EEA regions are available.
