WebSocket vs Polling Comparator
Sample: live chat app, 500 concurrent users
Example shown — replace it with your own use case and scale.

500
Result
How it works
- Describe your real-time use case.
- Enter your expected concurrent user count.
- Get a recommendation between WebSocket and polling.
The method
The recommendation weighs update frequency and concurrent scale against the overhead of each approach, favoring WebSocket for frequent updates at higher scale and polling for simpler, lower-frequency cases.
FAQ
When is polling actually the better choice?
Polling is simpler to implement and debug, and can be fine for low-frequency updates or small numbers of clients where WebSocket infrastructure isn't worth the added complexity.
Why does WebSocket scale better for real-time features?
A WebSocket keeps one persistent connection open per client and pushes updates only when there's new data, avoiding the repeated request overhead that polling adds at scale.
Does this account for server infrastructure I already have?
No — the comparison is based on general tradeoffs for your use case and scale; your existing infrastructure may shift the practical choice.
