VERDICT

Should I use Zenn?

Zennはエンジニアが技術・開発についての知見をシェアする場所です。本の販売や、読者からのバッジの受付により対価を受け取ることができます。 - zenn.dev

Depends. Use it if you write technical content for Japanese developers — it is free and authors can earn via book sales and reader badges. Skip it for English-language audiences or compliance-vetted publishing; public evidence is thin, so confidence is low.

Confidence

Low. Based on 7 public sources relevant to zenn.dev. Most 'Zenn' search results matched unrelated businesses (restaurants, EVs, audio, clothing), so confidence is low.
