I see you guys building absolute magic with Lovable in record time. Going from an idea to a fully functional app in a weekend is a superpower.
But here’s the harsh truth: speed often comes at the cost of security.
If your app handles user data, processes payments, or stores anything mildly sensitive, you cannot afford to skip a security check. To save you hours of headaches (and potential data leaks), I've put together a Copy-Paste Prompt Arsenal.
Drop these exact prompts into your Lovable chat to bulletproof your app right now:
🏗️ 1. The RLS & Storage Lockdown
Row Level Security (RLS) is like a bouncer for your database. Without it, anyone who finds your database URL can access everyone's data.
(Copy & paste this into Lovable):
Review all RLS policies in my Supabase database. Fix any policies that expose personally identifiable information, allow users to access other users' data, or permit privilege escalation. Also, check my storage bucket configuration to ensure private user files are in private buckets with proper access controls.
🔒 2. API, Auth & Bot Protection
Don't let unauthenticated users or bots bypass your UI and spam your endpoints directly.
(Copy & paste this into Lovable):
Review all API endpoints and Edge Functions for auth vulnerabilities. Flag any endpoints unauthenticated users can access. Check for XSS and SQL injection risks. Verify my password requirements enforce strong passwords, add rate limiting to sensitive endpoints, and ensure my login/signup forms have bot protection.
⚠️ 3. The Deadliest Mistake: Exposed API Keys
Never paste your raw API keys (like OpenAI or Stripe) directly into the Lovable chat! They live in your chat history forever and can be scraped if someone remixes your project.
(Copy & paste this into Lovable to check for leaks):
Review my codebase for exposed API keys or secrets. Check for hardcoded keys in frontend code, API calls that should go through Edge Functions, and any use of the Supabase service role key outside of Edge Functions.
🚀 Final Polish Before Launch
Always run Lovable's native "Review Security" button in the Publish section. It might give some false positives, but it’s free and catches the silly mistakes we all make when building fast.
Building fast doesn't mean building recklessly. Run these prompts, secure your data, and launch with peace of mind!
