What makes an MTProto proxy the "best" one?

Search for "best MTProto proxy" and you'll find dozens of pages listing server addresses that were live the day someone posted them — and dead by the time you try them. That's the core problem with proxy lists: an MTProto proxy is a free, often unofficial server that stays up for as long as its owner keeps paying for it and as long as no firewall has blocked it yet. There's no such thing as a permanently "best" proxy, only a currently working one.

The four things that actually matter

Instead of chasing a single "best" server, judge any MTProto proxy — including the ones you get from FoxProxy — on these:

• Is it actually alive right now? A proxy that worked yesterday tells you nothing about today. This is the single biggest reason free lists fail.
• What's the latency? A working proxy on the other side of the planet still feels sluggish. Lower round-trip time means faster message delivery and smoother voice calls.
• What secret type does it use? Plain secrets are easy for firewalls to fingerprint. Fake-TLS secrets (the ones starting with ee) disguise the connection as ordinary HTTPS traffic, which holds up much better against deep packet inspection.
• Who's publishing it, and how often? A list that hasn't been updated in a week is a list of dead servers with extra steps.

How FoxProxy picks its list

FoxProxy runs an automated pipeline, not a manually curated list. Every hour it collects proxy links posted across a set of Telegram source channels, opens a real TCP connection to each one to confirm it responds, measures latency, and ranks survivors from fastest to slowest. Only the top results for that hour get published to the channel — everything else, including anything that fails to connect, is discarded before it ever reaches you.

Each proxy is also only posted once. You won't scroll through the same three dead links reposted for a month; every entry in the channel was tested within the last hour.

A quick way to sanity-check any proxy yourself

If you're evaluating a proxy from any source, not just FoxProxy, three checks catch most dead entries before you waste time:

1. Does the secret look like a long hex string starting with ee? That's fake-TLS — prefer it over shorter, plain secrets.
2. Is the port a common one like 443 or 8443? Unusual ports are easier for a firewall to flag as suspicious before it even inspects the traffic.
3. How old is the post? Anything older than a few hours has a real chance of already being blocked or offline.

Rather than manually re-checking servers, the fastest path is to join a channel that already does the testing for you. FoxProxy posts freshly verified proxies every hour, with no account, no app, and no cost.
