Comparison
PostHog vs Spreelytics
Which one fits
PostHog is the better fit for product and engineering teams that want analytics, replays, experiments, feature flags and error data in one place. Spreelytics is the better fit for SaaS founders and small teams leaving GA4 who mainly want to see which channels bring paying customers, with revenue reporting built in.

- product analytics, session replay
PostHog and Spreelytics both sit in analytics and both offer a free tier, but they cover different ground. PostHog is a broad product data platform with replay, error tracking, feature flags, experiments and a data warehouse.
Spreelytics is narrower. It matches payments from Stripe, Paddle, Polar or Lemon Squeezy to the channel that earned them. It skips heatmaps, feature flags, experiments and self-hosting.

Who it is for
PostHog
Suited to product and engineering teams that want analytics, replays, experiments and error data in one place instead of several separate tools. Developers who work with AI coding assistants and want product data available in their editor are a clear fit. Teams that only need a single narrow tool may find the breadth more than they need.
Spreelytics
Suited to SaaS founders, marketers and small teams moving off GA4, Mixpanel or Amplitude who want to see which channels bring in paying customers. It fits teams that use Stripe, Paddle, Polar or Lemon Squeezy. It does not suit those who need heatmaps, feature flags, A/B experiments or a self-hosted install.
