As stated on https://developers.cloudflare.com/network/websockets/, you're free to make use of proxied websockets on the free plan for "low" volume of concurrent connections.
The page also explains what happens if your traffic is becoming high.

What happens if my site exceeds the number of concurrent WebSockets connections that Cloudflare expects?
Immediately, nothing. Cloudflare will allow occasional spikes in usage beyond our guidelines and we will not apply unnecessary limits.
Repeated spikes or high continued usage will prompt a dialogue. Cloudflare will reach out to learn more about your application. We will not impose limit errors for any application without contacting the customer unless we suspect that abuse or an attack is involved.
Customers whose usage claims a disproportionate percentage of resources for their current plan level may be asked to upgrade to the plan level that matches their needs.
