Intercom is leading the most aggressive AI shift with Fin AI Agent, Zendesk owns enterprise, Plain raised a Series A for its developer-friendly workflow, and Pylon exploded with Slack-Connect B2B support. In East Asia, KakaoTalk Channel, Naver TalkTalk, and Channel Talk define messaging-first support. Japan has KARTE Talk, Channel Talk JP, and Mercari running its own support stack. This piece breaks down each tool — strengths, weaknesses, pricing, and who should pick what, from solo founders to enterprise.

Intercom은 Fin AI Agent로 가장 공격적으로 AI 전환 중이고, Zendesk는 엔터프라이즈 헤비웨이트로 자리 잡았고, Plain은 개발자 친화 워크플로우로 Series A를 받았고, Pylon은 Slack-Connect 기반 B2B 지원으로 폭발 성장했다. 동아시아에서는 카카오톡 채널·네이버 톡톡·채널톡(Channel Talk)이 메시징 중심 지원을 정의하고, 일본은 KARTE Talk과 チャネルトーク, 메르카리의 자체 지원 시스템이 있다. 이 글은 각 도구의 강점·약점·가격·언제 무엇을 골라야 하는지를 1인 창업자에서 엔터프라이즈까지 분해한다.

The OTel spec and Collector, W3C Trace Context and B3 Propagation, OSS backends like Jaeger/Tempo/Zipkin, the observability 2.0 camp (Honeycomb, SigNoz), APM giants (Lightstep, Datadog, New Relic, Dynatrace), eBPF auto-instrumentation (Pixie, Beyla) — where to pick what, how to tame head vs tail sampling and cost, and how Korean and Japanese companies actually migrated.
