Softr Security Best Practices
Built a no-code app with Softr? Make sure your Airtable data and user access controls are properly secured before launch.
Verify your app follows these best practices automatically.
These best practices are derived from the actual security findings we see in Softr apps — not a generic OWASP list. Priority ordered: critical items close data-exposure gaps, high items prevent compromise, medium items reduce attack surface. Stack-specific guidance for Firebase included.

Security Best Practices
#1Keep every secret server-side
highSoftr apps connect to Airtable as a data source. If the API key is exposed in client-side code, attackers can directly query your entire Airtable base.
Implementation
Move all secrets server-side (environment variables, serverless functions). Rotate any keys previously in frontend code. Audit bundles for leftover credentials before each deploy.
#2Client-Side Data Filtering
highSoftr applies visibility rules in the browser rather than at the data layer. Users can intercept API responses to see records they shouldn't access.
Implementation
Enforce all security-relevant checks server-side. Treat client-side validation as UX only — attackers bypass the UI entirely by calling APIs directly.
#3Close: Weak Role-Based Access
mediumUser group permissions may only restrict UI visibility without enforcing access at the API level, allowing role escalation.
Implementation
Scan your deployed application with a security tool that understands this stack. Address the specific findings — generic best practices don't catch platform-specific misconfigurations.
#4Configure security headers
highSoftr-hosted apps often lack CSP, HSTS, and X-Frame-Options headers, leaving them vulnerable to XSS and clickjacking.
Implementation
Use parameterized queries, sanitize all user input, and render dynamic content with framework escaping (React JSX, not dangerouslySetInnerHTML).

Verify Your Softr App Security
Following best practices is the first step. Verify your app is actually secure with a comprehensive security scan.
Get Starter ScanFrequently Asked Questions
What's the minimum security I need for a Softr app?
The critical-priority items above are non-negotiable for any Softr app that handles user data: . Everything else is iterative.
Should I run a security scan before launching a Softr app?
Yes — unconditionally. The mitigations above are specific enough that a scan proves they're implemented correctly. "I followed the checklist" isn't evidence; "the scan came back clean" is.
Is Softr secure by default?
Softr provides secure infrastructure, but the application-layer configuration (listed above) is the developer's job. The default state of a Softr app before any security work typically has at least one critical-priority issue open.
