BREAKING: Supabase Realtime Latency Issues Identified — Workarounds Available

Supabase experiencing significant Realtime latency. Immediate workarounds and status checks inside.

BREAKING: Supabase Realtime Latency Issues Identified

What's Down

Supabase is currently experiencing elevated latency on Realtime subscriptions. This affects:

WebSocket connections for real-time data sync

Live query subscriptions

Presence tracking features

Real-time collaboration features

Note: PostgreSQL database operations and REST APIs appear to be functioning, though performance may be degraded.

How to Check If You're Affected

1. Monitor Supabase Status Page: Visit [status.supabase.com](https://status.supabase.com) for official updates 2. Check Console Errors: Look for WebSocket connection timeouts or delayed subscription callbacks 3. Test Connectivity: Attempt a simple Realtime subscription—if messages take >5 seconds to arrive, you're affected 4. Review Network Tab: Browser DevTools should show delayed WebSocket frames

Immediate Workarounds

1. Implement Polling as Fallback

```javascript // Replace Realtime subscriptions temporarily setInterval(async () => { const { data } = await supabase .from('your_table') .select('*') .eq('id', targetId); // Update UI with fresh data }, 2000); // Poll every 2 seconds ```

2. Increase Connection Timeouts

Modify your Supabase client initialization: ```javascript const supabase = createClient(URL, KEY, { realtime: { params: { eventsPerSecond: 10, }, }, }); ```

3. Batch Realtime Subscriptions

Reduce active subscriptions:

Subscribe to tables only when visible

Unsubscribe when users navigate away

Consolidate multiple subscriptions into single listeners

4. Use REST API with Webhooks

Temporarily replace Realtime with:

Database webhooks triggering HTTP callbacks

Server-sent events (SSE) for pushing updates

Scheduled API polling at longer intervals

Alternative Solutions

Short-term Alternatives:

Firebase Realtime Database — Drop-in replacement for Realtime features

Socket.io + Node backend — Host your own WebSocket server

AWS AppSync — Managed GraphQL real-time service

Pusher/Ably — Dedicated real-time infrastructure

Mitigation Strategy:

Implement graceful degradation to REST API when Realtime fails

Add retry logic with exponential backoff

Display user-facing notifications about delayed updates

Log latency metrics for post-incident analysis

What We Don't Know

Root cause: Supabase hasn't published technical details yet

Affected regions: Unclear if this is global or regional

ETA for resolution: Check status page for updates

Data loss risk: Unlikely, but unconfirmed

Next Steps

1. Subscribe to status.supabase.com for real-time updates 2. Implement polling fallback NOW while investigating 3. Test your error handling — ensure graceful degradation 4. Monitor your logs for subscription failures 5. Plan migration if outage extends beyond 2+ hours
