The Verdict
Joplin is built for privacy advocates and developers, with a focus on markdown and encryption. PostHog targets developers and startups and leads with product-analytics and session-replay.
Pricing is close: PostHog starts at $0/mo versus $2.99/mo for Joplin — not a deciding factor on its own.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, PostHog offers broader built-in capabilities (7 features vs 6), while Joplin takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for developers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: PostHog has a slight overall edge — but if free and open-source matters most to you, Joplin may still be the right call.
