The Verdict
PostHog is built for developers and startups, with a focus on product-analytics and session-replay. Sprig targets product managers and ux researchers and leads with in-app-surveys and session-replay.

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 Sprig takes a more focused approach — which can mean a simpler, faster onboarding experience.
