PostHog
Last reviewed: 2026-05-23
Our take
PostHog is the right pick for indie SaaS, AI builders, and PLG companies that want analytics + replay + flags + LLM obs in one tool. We use PostHog ourselves on gtmpod. The 2025 LLM observability add-on competes with LangSmith for token cost tracking. For mature SaaS that already pays Amplitude $50k/yr, PostHog isn't a switch-justifier; for new builds it's the default.
Who it's for: Indie + early-stage SaaS. AI builders. PLG companies under 1M MAU.
Pricing
Custom
Free tier (1M events + 5k replays/mo). Pay-as-you-go after: $0.000248/event. Predictable enterprise tiers.
