The Verdict
Majestic is built for link builders and seo professionals, with a focus on site-explorer and trust-flow. 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 $49.99/mo for Majestic. That $49.99/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.
PostHog edges out on user ratings (4.5 vs 4.1). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Feature-wise, PostHog offers broader built-in capabilities (7 features vs 6), while Majestic takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: PostHog has a slight overall edge — but if largest backlink database available matters most to you, Majestic may still be the right call.
