The Verdict
Plane is built for developers and open source advocates, with a focus on cycles and modules. PostHog targets developers and startups and leads with product-analytics and session-replay.
On pricing, PostHog is the clear winner for budget-conscious users — starting at $0/mo compared to $7/mo for Plane. That $7/mo difference adds up quickly for growing teams.
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 Plane takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for developers, startups — 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 open source and self-hostable matters most to you, Plane may still be the right call.
