StackMatch Editorial verdicts
Bylined · No vendor influencePostHog has quietly become the default for product analytics, session replay, feature flags, and experiments in one tool. Each individual product is good enough, the bundle is undefeatable on price, and self-hosting is genuinely viable.

Side-by-Side Comparison
Objective metrics, no spin.
Engineering-led early-stage teams that want an all-in-one platform, or regulated/data-sovereign organizations that self-host.
Non-technical teams (configuration is code-forward) or large enterprises that need mature SSO, governance, and dedicated support (Amplitude fits better).
Data-engineering-forward teams who want their warehouse as the source of truth, with customer data flowing back out to tools from there.
Marketing-ops-heavy teams — Segment has a broader marketing tool ecosystem and is more intuitive for non-engineers.
