## What it is
SSH3 is a research-driven reimplementation of the SSH protocol that runs remote terminal sessions over QUIC, TLS 1.3, and HTTP/3. It offers faster session establishment, HTTP-based authentication (OAuth 2.0, OpenID Connect), UDP port forwarding, and server invisibility to port scans.

## Use cases
- connect to remote servers over ssh with faster session establishment
- authenticate ssh sessions with oauth or openid connect instead of keys
- forward udp ports to a remote server
- hide an ssh server from internet port scanners
- run remote terminals over http/3 and quic

## When to choose
- you want faster ssh session setup over high-latency links
- you need modern authentication via identity providers like Google or GitHub
- you need UDP port forwarding or resistance to port scanning
- you are experimenting with next-generation remote access protocols

## When to avoid
- you need battle-tested, widely deployed ssh for production infrastructure
- your environment requires OpenSSH compatibility or existing ssh tooling
- you need guaranteed throughput improvements - only session establishment is faster
- you need a stable, standardized protocol - the spec is still an Internet-Draft
