Plus Korean players (Newneek, Uppity, Stibee) and Japanese (note.com, theletter). Closes with concrete picks for "start free," "growth-first," "open source," and "Korea/Japan."

Medium reversed course in 2024, almost dropping its paywall for new readers and recommitting to free reach. Substack became the newsletter default. Mirror.xyz declined alongside the Web3 cycle. Posthaven still lives on Maciej Cegłowski one-line promise — 5 USD per month for a site that lasts forever — while his other site Pinboard was sold in September 2025. The 2024 Automattic vs WP Engine fight pushed many users back toward self-hosted WordPress.org. Ghost added ActivityPub to enter the fediverse. Bear Blog, Mataroa, and Write.as became the minimalist standard. Korea has a four-way split between Tistory, Brunch, Naver Blog, and velog. Japan still runs on Hatena Blog, note.com, Ameba, and livedoor blog. This guide walks the whole map split into managed, developer, self-hosted, and micro tiers, and gives a scenario-by-scenario recommendation for who should pick what.

Medium은 2024년 새로운 독자를 위한 페이월을 거의 걷어내며 무료 발행에 다시 무게를 실었고, Substack은 뉴스레터의 표준이 되었으며, Mirror.xyz는 Web3 사이클이 식으면서 사용자가 줄었다. Posthaven은 Maciej Cegłowski의 한 줄짜리 약속 — 월 5달러로 사이트가 영원히 살아남는다 — 으로 여전히 살아 있고, 같은 사람이 운영하던 북마크 사이트 Pinboard는 2025년 9월 매각되었다. WordPress.com과 Wordpress.org는 2024년의 Automattic vs WP Engine 분쟁 이후 자체 호스팅 진영이 다시 주목받고, Ghost는 ActivityPub 통합으로 페디버스에 발을 들였고, Bear Blog·Mataroa·Write.as는 미니멀 글쓰기의 표준으로 자리잡았다. 한국은 티스토리·브런치·네이버 블로그·velog의 4강 구도, 일본은 はてなブログ·note.com·アメーバ가 여전히 강하다. 이 글은 매니지드·개발자·자체 호스팅·마이크로 4분류로 전체 지형을 정리하고, 누가 무엇을 골라야 하는지를 시나리오별로 답한다.
