Is Bubble.io Secure for Production Apps?

Decloak is an AI-powered web security intelligence platform that scans a site's HTTP/TLS posture, JavaScript, and third-party scripts to produce a report anyone can read. This guide is part of Decloak's library of practical, source-backed security guidance.

Key takeaways

• Bubble.io is a cloud - native no - code PaaS that meets SOC 2 Type II, GDPR and ISO 27001 standards.
• The platform runs on shared AWS infrastructure by default; enterprise customers can request a dedicated instance.
• Security missteps such as an unrestricted Data API or exposed service_role key are common and detectable by Decloak’s vibe - coded platform security layer.
• Harden your Bubble app by enabling privacy rules, restricting API access, using custom domains with proper DNS, and regularly scanning with Decloak’s free scan.

What security certifications does Bubble.io have and why do they matter?

Bubble.io holds SOC 2 Type II, GDPR and ISO 27001 certifications, meaning independent audits have verified its security controls, data - handling practices and incident - response processes. These certifications give you assurance that the underlying platform encrypts data at rest and in transit and follows industry - standard governance.

How does Bubble.io host apps and what implications does multi - tenant hosting have?

By default Bubble hosts apps on a shared, multi - tenant AWS environment. All tenants share the same underlying servers, which reduces cost but means you rely on Bubble’s isolation mechanisms. For high - risk workloads you can upgrade to a dedicated instance that runs on an isolated AWS server with its own static IP and region choice, providing stronger separation from other customers.

Which common misconfigurations expose Bubble apps and how can I detect them?

The most frequent issue is an open Data API that allows anyone to read or write database tables. Bubble also lets developers embed service_role keys in client - side JavaScript, which grants full database access. Decloak’s vibe - coded platform security layer automatically flags these problems: it reports a publicly readable table name, row count and field names, and it identifies a service_role key shipped to the browser.

How can I secure the Bubble Data API?

1. Open the Data tab in the Bubble editor.
2. For each data type, click Privacy and create rules that limit View and Modify actions to authenticated users or specific roles.
3. Disable the Expose as a public API toggle unless you need external access.
4. If you must expose an API, generate a unique API token and require it in the Authorization header for every request.
5. Re - run a Decloak free scan to verify the API is no longer publicly reachable.

What steps should I take to protect service_role keys?

• Never include the service_role key in client - side code or page headers.
• Store the key in server - side actions or custom plugins that run only on Bubble’s backend.
• Rotate the key regularly from the Settings → API section.
• Use Decloak’s free scan to confirm the key is no longer present in the rendered page source.

How do I configure custom domains and DNS securely?

1. In the Bubble editor, navigate to Settings → Domain / Email.
2. Add your custom domain (e.g., www.example.com).
3. Create a CNAME record pointing the subdomain to app.bubble.io as instructed.
4. Enable Force HTTPS to ensure all traffic uses TLS.
5. Verify the domain in Bubble and run a Decloak free scan; the HTTP/TLS posture layer will report certificate validity, protocol versions and cipher strength.

Should I use Bubble’s built - in authentication or external providers?

Bubble supports native email/password login, OAuth social providers and enterprise SSO (SAML/OIDC). For sensitive apps, enable multi - factor authentication (MFA) on user accounts and configure SSO to centralise identity management. This reduces the attack surface compared to relying solely on the built - in email/password flow.

How often should I scan my Bubble app with Decloak?

Run a free scan after any major change - new workflow, API endpoint, or privacy rule adjustment. Additionally, schedule a weekly scan using Decloak’s REST API (available on Pro and higher plans) to catch regressions automatically.

What additional security layers does Decloak offer for Bubble apps?

Beyond the free scan, Starter and higher plans add DNS record analysis and subdomain takeover detection, helping you verify that custom domain DNS is correctly configured. Enterprise adds Active Security Testing and AI Pentesting, which can safely probe the exposed Data API (if any) for real exploitation attempts, providing confirmed findings that influence your overall security score.

Where can I learn more about Decloak’s detection of Bubble misconfigurations?

See the journal post "Uncloaked: Even an API Security Testing Company Got Breached by an Unprotected Database" for real - world examples of the same issues you might face on Bubble.

Summary

Bubble.io provides a compliant, scalable no - code platform, but security still depends on how you configure privacy rules, API access and credentials. Use Bubble’s built - in privacy settings, avoid exposing service_role keys, enforce HTTPS, and validate your setup with Decloak’s free scan and higher - tier layers for continuous assurance.
