Flusk Review - Improving Bubble Security Measures

Most of the concern about no-code apps like Bubble is that people believe it does not have solid security measures. While this is not necessarily true, it can easily be improved with a few extra precautions, and if you do not want to do this yourself, there is always Flusk.

Flusk was created with the idea of improving Bubble's security measures. It offers all sorts of ways to improve the security of the Bubble app and just generally protect your sensitive data and provide a secure environment.

The problem: Bubble app security

Bubble.io is a popular choice for developers looking to build and deploy apps quickly. Security is crucial in protecting user data and privacy within the Bubble.io platform. However, concerns are growing about the platform’s built-in security capabilities.

Security limitations

Person working on security limitations

One of the most pressing issues with Bubble.io as a no-code platform is the security risks and considerations due to the lack of solid, built-in security checks. This lack requires the integration of third-party security tools that provide more extensive monitoring and auditing services.

These tools are not just add-ons, but essential components for the security of applications built on top of Bubble.io.

Data vulnerabilities

Another major concern is the potential for data leakage for apps built with Bubble.io. The configuration of the platform, particularly in terms of privacy rules and API workflows, can leave gaps that can lead to data breaches.

Compliance Challenges

Guaranteeing compliance with strict regulations, such as the General Data Protection Regulation (GDPR), is also a challenge for Bubble.io. The platform does not naturally guarantee compliance, pushing developers towards third-party solutions that can provide the necessary assurances and documentation to meet these regulatory requirements.

Lack of proactive security features

Bubble.io also lacks security features that can proactively detect and address vulnerabilities in new deployments. This flaw means that any update or change to an application could introduce new security risks that are not immediately identified or addressed by the platform itself.

Manual security management

Finally, the dependence on manual management of security issues is a significant drawback. Bubble.io does not provide sufficient tools to resolve security issues within its environment. Developers must rely on external documentation and support.

While Bubble.io allows for fast application development, it fails to provde the best security infrastructure. Developers are forced to look for additional security solutions to protect their applications from vulnerabilities, ensure compliance with privacy laws.

The solution: Flusk

Flusk provides essential security and monitoring for Bubble.io apps. It automatically checks over 20 security points each time you deploy a new version. You don’t have to manage security; Flusk does it for you. By integrating Flusk, developers can ensure their Bubble.io projects are not just efficient but also part of a secure platform with protective measures.

Flusk also helps you monitor your app’s health. It detects and logs errors automatically. This means you can fix issues before users even notice them.

Need to deploy a new app version? Flusk’s smart deployment feature makes this easy. It lets you launch new updates when no users are online.
