Challenge

Doxy.me is a global telemedicine platform that allows doctors and patients to connect safely in the browser - no downloads, no installations. When doxy.me powers over 8 million minutes of care across more than 290,000 provider and patient encounters each day, reliability is critical.

But their old realtime provider was failing. Doxy.me was struggling with:

• Ghost check-in sounds and chat messages arriving late or not at all.
• Lag and even full 24-hour outages.
• High costs and fragile systems that engineers were afraid to touch.
  ‍

Realtime wasn’t just a problem - it had become the biggest risk and expense in their platform.

‍

Solution

Using Ably’s Pub/Sub WebSocket infrastructure (replacing the previous HTTP polling approach), we:

Moved all realtime traffic to Ably’s modern WebSocket-based Pub/Sub architecture.

• Built new flows for presence, chat, and signaling to make connections stable.

• Completed the migration with zero downtime, even during 250k+ daily calls.

What was planned as a 12-month project was delivered in under 6 months.

‍

Impact

The improvements were clear right away:

• 65% lower realtime infrastructure costs.

• 95% fewer patient queue problems.

• 99% fewer app crashes from signaling errors.

• 100% gone ghost check-in chimes.

• The system now handles customers with 10,000+ patients daily without issues.
  

Realtime went from being Doxy’s biggest weakness to a secure foundation for growth.

Together with Ably, Galeyo helped Doxy.me turn realtime from a constant risk into a reliable, scalable core of virtual healthcare.
