PostHog’s reliability issues
While we applaud their transparency, PostHog’s eight documented incidents in a six-month span raise serious questions for teams that have enough to focus on with their own product.
Logs permanent data loss
ClickHouse bug deleted all S3 data over 8 hours with zero alarms. Used experimental feature not recommended for production. Unrecoverable.

Frequently asked questions
Amplitude’s AI features make its platform fully accessible through AI, with a Global Agent that can answer any question and specialized agents that can monitor and take action based on your data. The platform also features AI Feedback, AI Visibility, and an MCP server. Amplitude’s AI analytics platform stands apart from competitors who often have surface-level AI or lack autonomous agents.
PostHog has experienced several reliability issues over a six-month time span, including a permanent data loss incident and seven other public postmortems, as reported on their own website and by their customers on social media apps such as X. Amplitude, in contrast, offers enterprise-grade security and robust data governance with schema validation. (1, 2, 3)
Along with its real-time experimental data, precise targeting, and enterprise-level controls, Amplitude was named the only leader in the 2024 Forrester Wave™ for Feature Management and Experimentation.
Yes, Amplitude provides full-coverage, targeted session replays and uses agentic AI for aggregate session analysis.
PostHog’s pricing model may seem cheaper for some teams, but it becomes more expensive than Amplitude’s in the long run. While PostHog uses event-based pricing, Amplitude's MTU-based pricing is more predictable, rewarding deeper instrumentation without punishing users with unexpected costs. For self-hosted PostHog deployments, the sticker price ignores the significant hidden costs of infrastructure and maintenance, which can run between $5K–$15K per month.
PostHog’s breadth often comes at the cost of depth. Each individual PostHog module that compares to an Amplitude feature, like Analytics, Experimentation, Session Replay, and AI Agents, is less mature than our dedicated, best-in-class capabilities. For teams needing more than a multitool, PostHog’s approach may fall short. On the other hand, Amplitude’s integrated platform delivers broad capabilities that play off each others’ strengths for deeper and more reliable insights, action, and data.
Choosing self-hosted PostHog requires significant infrastructure and maintenance costs (estimated at $5K–$15K/mo) that are not reflected in the sticker price. It also places the burden of security, upgrades, and support on your team. With Amplitude, customers get a fully managed platform with dedicated support and established enterprise compliance (like SOC 2 and HIPAA).
Yes. Amplitude’s Starter plan is robust, offering 10k MTUs or 10M events. This is already substantial for early-stage teams.
Startups can also apply for Amplitude's startup scholarship programs, which give free access to our Growth plan for a year. Spend $0, get 1.2 billion events per year (100 million events per month). Scholarships include all the tools startups need to understand users and find product-market fit faster—Analytics, Experimentation, Session Replay, and Activation.
While PostHog’s free tier (1M events + 5K replays) is also generous, the real cost comparison occurs as you scale. Amplitude’s platform consolidation provides significant savings compared to the additional tools you’d have to stitching together with PostHog for feature parity.
While PostHog presents itself as focused on developer workflows, Amplitude is built for your entire company. Product managers, marketers, data scientists, and engineers can all work from the same trusted data to collaboratively build what your users want. But easier self-serve access for your whole team doesn’t mean Amplitude sacrifices developer support—our SDK/API quality and technical credibility deliver everything that builders care about.
Amplitude delivers on mature enterprise requirements, including governance, permissions, SSO/SCIM, data quality tools, and compliance certifications like SOC 2 and HIPAA. PostHog is still building toward this level of enterprise readiness.
We’re glad you found our page, then. Many startups take an initial interest in PostHog for the breadth of lightweight capabilities they can get at a budget price—considered “good enough” in the immediate term. That’s why we’ve focused on explaining how Amplitude’s stronger analytics platform can actually be more affordable for startups, is extremely easy to implement, and has a depth of features that can scale with a startup’s success.
If you aren’t a startup, we recommend choosing an AI analytics platform that can meet your more mature needs, like Amplitude.
