Top 10 PostHog Alternatives in 2026

PostHog has carved out a genuinely interesting position in the market. Rather than solving one problem well, it bundles product analytics, session replay, feature flags, A/B testing, and a data warehouse into a single platform, with the idea that product engineers should not need five separate subscriptions to understand what their users are doing.

That pitch works well for many teams. But PostHog is not the only platform thinking this way, and depending on your priorities such as cost, depth of analytics, observability coverage, or enterprise readiness, there are compelling reasons to look elsewhere.

I evaluated the leading alternatives across real-world criteria and narrowed the list down to 10 tools worth considering.

PostHog features

PostHog is an open-source product OS that covers product analytics, web analytics, session replay, feature flags, A/B testing, surveys, and a built-in data warehouse with 120+ sources and destinations. Pricing is usage-based with generous free tiers — 1 million analytics events, 5,000 session replays, and 1 million feature flag requests per month at no cost. It's self-hostable, ships with an SQL editor, and positions itself as the single source of truth for how customers use your product.

Top 10 PostHog alternatives in 2026

Here's how each tool compares:

1. Better Stack

Better Stack approaches the all-in-one problem from the observability side rather than the product analytics side, and the result is a platform that covers more of your production stack than PostHog ever will, at a significantly lower cost.

Where PostHog centers its platform around understanding user behavior, Better Stack centers it around keeping your product running. That means real-time error tracking, log management, distributed tracing, infrastructure monitoring, incident management, on-call scheduling, uptime monitoring, and status pages, all under one roof, all sharing the same data and alert routing. When something breaks, you're not context-switching between tools to find out why.

🌟 Key features

• Real-time error tracking with AI-powered debugging and pre-made prompts for Claude Code and Cursor
• ClickHouse-powered log search querying billions of records in under a second
• OpenTelemetry-native distributed tracing with service maps
• AI SRE powered by Claude with MCP server integration for automated root cause analysis
• Native incident management with intelligent alert grouping in Slack and Teams
• Uptime monitoring with 30-second check intervals globally
• Sentry-compatible error tracking at a fraction of the cost
• Data warehouse with serverless ClickHouse API for running analytical SQL queries

➕ Pros

• Replace PostHog's observability use cases plus your incident management and uptime tools with one platform
