Worth it

Should I use Zeal?

Zeal - Offline documentation browser. Your personal reference... - zealdocs.org

· 6 days ago

Buy it if you're a developer who wants free offline API docs on Windows or Linux — just install it. Don't expect vendor support, cloud sync, or team features, and don't confuse it with the unrelated Zeal contract-AI SaaS at zealdocs.com.

Confidence

Medium. Based on ~35 public sources. Note: many review, pricing, and G2 items describe an unrelated contract-AI SaaS also named Zeal (zealdocs.com), not this open-source documentation browser.
