Base44 Security Best Practices
Protect your Base44-built application with these essential security practices. From secret management to database security.
Verify your app follows these best practices automatically.
Base44 makes building apps fast, but security requires intentional effort. These best practices will help you ship secure applications without slowing down your development.
Quick Wins
Security Best Practices
#1Move All Secrets to Environment Variables
criticalBase44-generated code often includes API keys directly in source files. Move all secrets to server-side environment variables.
Implementation
Use your deployment platform's environment variable settings (Vercel, Netlify, etc.)
#2Enable Row Level Security (RLS) on All Tables
criticalSupabase RLS is your primary defense against unauthorized data access. Without RLS, anyone with the anon key can read all data.
Implementation
Enable RLS on each table and create policies that restrict access using auth.uid()
#3Review AI-Generated Authentication Code
criticalAI-generated auth code often has subtle vulnerabilities. Never accept authentication implementations without thorough review.
Implementation
Manually verify JWT handling, session management, and password hashing
#4Add Security Headers
highConfigure Content-Security-Policy, X-Frame-Options, HSTS, and other security headers.
Implementation
Add headers in your hosting configuration (Vercel, Netlify) or Next.js config
#5Validate All User Input Server-Side
highAI-generated code often trusts user input. Always validate on the server.
Implementation
Use validation libraries like zod or joi for all incoming data
#6Disable Source Maps in Production
mediumSource maps expose your original code. Disable them before deploying.
Implementation
Set productionBrowserSourceMaps: false in your build config
Common Mistakes to Avoid
Leaving API keys in frontend code
Anyone viewing your JS bundles can extract these keys
Move all secrets to server-side environment variables
Deploying without RLS enabled
Your entire database is publicly accessible via the anon key
Enable RLS on all tables and write appropriate policies
Trusting AI-generated security code
AI prioritizes functionality over security best practices
Manually review all auth, validation, and access control code
Verify Your Base44 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
How do I find hardcoded secrets in Base44 code?
Search your codebase using grep: 'grep -r "sk-" .' for OpenAI keys, 'grep -r "sk_live" .' for Stripe. Also search for 'apiKey', 'secret', and 'password'. Move all found secrets to environment variables.
Does Base44 configure database security automatically?
No. Like other AI coding tools, Base44 creates functional code but skips security configuration. You must manually enable RLS on Supabase tables and write policies.
What should I check before launching a Base44 app?
1) All secrets in environment variables, 2) RLS enabled on all database tables, 3) Security headers configured, 4) Run a VAS security scan to catch anything you missed.
