PostHog

What makes PostHog different

PostHog is fundamentally designed for product engineers who want to own their analytics stack without vendor lock-in. Unlike traditional SaaS analytics platforms, PostHog is open-source and can be deployed on-premises, giving teams full control over their data and infrastructure costs. The platform bundles analytics, feature flags, experimentation, and a built-in data warehouse into a single integrated Product OS—eliminating the need to stitch together multiple tools.

PostHog’s philosophy centers on transparency and accessibility. The company explicitly avoids enterprise sales calls and seat-based pricing, instead offering generous free tiers (98% of customers use PostHog free) and simple usage-based billing. The built-in data warehouse enables users to combine product data with external sources (Stripe, error tracking, support platforms) in a single queryable location, reducing the friction of multi-tool data integration.

Pricing model

PostHog operates on a usage-based model with generous free tiers across all products:

• Product Analytics: Free tier includes unlimited events; paid plans charged per event captured
• Session Recording: Free tier included; additional recordings billed per 10k sessions
• Feature Flags & A/B Testing: Free tier with limited flags; additional flags priced per flag or experiment
• Data Warehouse: Free tier included with ingestion and query limits; overage pricing per million rows queried

The company emphasizes that 98% of users stay on the free tier indefinitely. Paid customers pay only for what they use, with no minimum contracts or per-seat charges. This approach avoids the “sticker shock” of traditional analytics platforms and scales naturally with product growth.

When it fits

• Early-stage and growth-stage startups wanting to control costs while building product analytics capabilities
• Engineering-heavy teams comfortable with SQL and self-service data exploration
• Companies with privacy or compliance requirements needing on-premises deployment options
• Product teams combining analytics, feature flags, and experimentation in a single platform
• Data-driven organizations that need to join product telemetry with external business data sources

When it doesn’t

PostHog is a poor fit for non-technical business users expecting point-and-click interfaces without SQL knowledge. Organizations requiring 24/7 dedicated support and SLAs tied to enterprise contracts should evaluate alternatives.

Open source

PostHog is fully open-source (MIT license) and the codebase is available on GitHub. Users can self-host and retain complete control over deployment, scaling, and data residency.
