Erlang/OTP&rsquo;s battle-tested concurrency model makes it a favorite for telecom-grade, low-latency backends, and the HTTP layer you pick determines latency, memory footprint, and how much boilerplate your team writes. In 2026 the choice still comes down to three projects: <strong>Cowboy</strong>, <strong>MochiWeb</strong>, and <strong>Yaws</strong>. They look interchangeable at a glance — all three speak HTTP/1.1 on the Beam — but they target completely different jobs.</p>
