Real-Time Database Sync Not Updating in Lovable
Data changes in your Lovable app don't appear in real-time for other users. When one user creates, updates, or deletes a record, other users (or even the same user in another tab) don't see the change until they manually refresh the page.
Real-time functionality is essential for chat apps, collaborative tools, dashboards, and notification systems. When it breaks, your app feels sluggish and outdated compared to modern web applications.
The issue may be subtle — some tables update in real-time while others don't, or real-time works for inserts but not updates or deletes.
Error Messages You Might See
Realtime connection closed
Subscription error: not authorized
Channel error: timeout
Max Realtime connections reached
Common Causes
- Supabase Realtime not enabled for table — The database table doesn't have Realtime publication enabled in Supabase settings
- Missing subscription setup — The frontend code doesn't subscribe to real-time changes using Supabase's on() method
- RLS blocking Realtime — Row Level Security policies prevent the subscription from receiving updates the user should see
- Channel not cleaned up — Multiple subscriptions accumulate on component re-renders, causing memory leaks and missed events
- Free tier limits — Supabase free tier limits concurrent Realtime connections, dropping connections when exceeded
How to Fix It
- Enable Realtime for the table — In Supabase dashboard → Database → Replication, enable Realtime for the specific table
- Set up subscription correctly — Use supabase.channel('table-changes').on('postgres_changes', { event: '*', schema: 'public', table: 'your_table' }, callback).subscribe()
- Check RLS policies — Ensure your RLS policies allow SELECT for the subscribed user on the rows they need to see
- Clean up subscriptions — In React, return a cleanup function from useEffect that removes the subscription when the component unmounts
- Monitor connection status — Subscribe to channel status changes to detect and handle disconnections

Full-stack developer experienced in fixing and deploying AI-generated apps from Lovable, Bolt.new, Cursor, and Replit. I specialize in debugging Supabase integration issues (auth flows, RLS policies, database connections), fixing broken deployments, resolving routing/blank screen problems, and cleaning up messy React/Vite codebases. I also build production apps with the Claude API and have shipped a Mac desktop dev tool (Nexterm from scratch. Based in Hong Kong, fast turnaround.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

Get HelpFrequently Asked Questions
How many real-time connections can I have on the free tier?
Supabase free tier allows up to 200 concurrent Realtime connections. Each browser tab or user session uses at least one connection. If you exceed this, new connections are rejected.
Does Realtime work with Row Level Security?
Yes, but the RLS policies must allow the subscribing user to SELECT the rows they want to receive updates for. If RLS blocks the query, the subscription won't receive events.
