Unlimited AI consumption on a fully agentic analytics platform 2. Strong SLAs with public market accountability 3. Proactive data quality detection, tools for remediation 4. Deep marketing analytics, predictive cohorts, and real-time integrations 5. Rich in-app engagement and AI-powered personalization ###### PostHog 1. Hard caps on AI use with gaps in the sense-decide-act loop 2. Reliability concerns with critical infrastructure outages (8 in six months) 3. Reactive to cleanups and poorly governed datasets 4. Limited marketing views and no predictive cohorts 5. No guides or AI-powered personalization ### 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.

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](https://posthog.com/handbook/company/post-mortems), [2](https://github.com/PostHog/post-mortems/blob/main/2026-02-20-posthog-us-logs-data-loss.md), [3](https://x.com/BaroniaRuchir/status/2016598483927433384?s=20)) 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](https://amplitude.com/blog/forrester-wave-experimentation-leader). Yes, Amplitude provides full-coverage, targeted session replays and uses agentic AI for aggregate session analysis. No. Amplitude's free plan includes 2 million events per month, double PostHog's 1 million, and comes with session replay, unlimited feature flags, web experimentation, and unlimited seats at no cost. Paid plans scale with your event volume, with no overage penalties as you grow. For example, at 5 million events, Amplitude Plus costs $2,600 per year versus $6,720 on PostHog, saving you $4,120 annually. 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. Amplitude delivers more depth in every capability the two platforms share. PostHog ships more individual modules, but each one that overlaps with Amplitude, including analytics, experimentation, session replay, and AI agents, is a lighter-weight version of Amplitude's dedicated product. PostHog's breadth is built for developers who want a multitool. Amplitude's platform is built for the entire product, marketing, engineering, and data teams, with capabilities that compound: session replays connect to behavioral cohorts, experiment results feed analytics, and AI agents work across all of it. Teams that outgrow surface-level answers get deeper, more reliable insights from Amplitude without stitching modules together. 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 Free plan includes 2 million events per month, with session replay, unlimited feature flags, web experimentation, AI agents, and unlimited seats included at no cost. That's double PostHog's free event allowance (1 million events plus 5,000 replays), and it covers the full workflow most early-stage teams need to find product-market fit. Startups that need more can apply for [Amplitude's startup scholarship](https://amplitude.com/startups). Qualifying teams (under $10M raised, fewer than 20 employees) get one year of the Growth plan free: 1.2 billion events per year, or 100 million events per month, with Analytics, Feature and Web Experimentation, Session Replay, and Activation included. Over 96% of applicants are approved. The real comparison shows up as you scale. PostHog bills each product on its own meter, so replays, feature flags, and surveys stack on top of event costs. Amplitude's platform includes those capabilities in one plan. 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](https://amplitude.com/security-and-privacy), 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.
