Who should pick whom
Pick PostHog if you want product analytics, flags, and replay together, and you are ready to run or buy that platform. Pick Replayly if you only need session replay and heatmaps, with privacy defaults and a smaller app to operate. Also see PostHog alternatives.
Frequently asked questions
Why would I pick Replayly if PostHog also self-hosts?
Because you may not want to operate or adopt a full product-analytics platform. Replayly is smaller: session replay, heatmaps, and privacy defaults. Pick PostHog if you already want that wider platform.
Is Replayly cheaper than PostHog?
It depends on volume and which PostHog products you enable. Replayly publishes flat plan prices. Compare your expected usage on PostHog's current pricing page rather than using a frozen third-party figure.
Does Replayly include feature flags or product analytics?
No. Replayly does not ship flags, funnels, or a general analytics suite. If those are required, PostHog or a dedicated analytics tool is the better fit.
