SupaStory vs PostHog

Understanding PostHog Pricing

PostHog has built something genuinely impressive: an open-source product analytics platform that bundles analytics, session replay, feature flags, A/B testing, and surveys into a single product. The pricing model is usage-based, which can be a blessing or a headache depending on your traffic.

PostHog's free tier is generous. You get 5,000 session recordings per month, 1 million analytics events, and access to most features. After the free tier, you pay per recording (starting at $0.005 per recording) and per event.

The catch with usage-based pricing is unpredictability. If your traffic spikes during a launch or marketing campaign, your bill spikes too. Some teams love this model because you only pay for what you use. Others find it stressful.

Product Analytics vs UX Issue Detection

PostHog and SupaStory are built for fundamentally different jobs. PostHog answers questions like: how many users completed onboarding? Which features drive retention? What does my conversion funnel look like?

SupaStory answers different questions: what specific UX issues are blocking conversions? How much revenue is each issue costing? What code change will fix this problem? Can you open a PR for me?

PostHog is a measurement tool. SupaStory is a fix-it tool. They are complementary, not competitive, in many cases.

Session Replay: Built-in Feature vs Core Product

Session replay in PostHog is one feature among many. It works, it records sessions, and you can watch them. But PostHog does not apply AI to automatically analyze those recordings. You still need to watch sessions yourself to find issues.

In SupaStory, session replay is the foundation that everything else is built on. Our AI watches every session, identifies patterns across thousands of recordings, detects UX issues, estimates their conversion impact, and generates code fixes. The session replay is not just a recording feature; it is the data source for an entire AI-powered optimization pipeline.

The AI Gap

PostHog does not generate code fixes. It does not create GitHub PRs. It does not estimate the dollar impact of UX issues. These capabilities simply are not part of what PostHog is trying to do, and that is fine. It is a product analytics tool, not a UX repair tool.

If you want AI that goes beyond analytics and actually produces actionable code changes, that is what SupaStory was designed for.

Pricing Predictability

PostHog's usage-based model means your costs scale with traffic. That is great when you are small, but it can get expensive at scale. A site with 100K monthly sessions would pay well over $500/mo just for session replay.

SupaStory's pricing is flat and predictable. $149/mo for Startup, $299/mo for Growth. Unlimited session replays on both. Your bill does not change when traffic spikes.

When to Use PostHog vs SupaStory

Use PostHog if you need a comprehensive product analytics suite with funnels, cohorts, feature flags, and A/B testing. It is one of the best open-source options available and the free tier is excellent for startups.

Use SupaStory if your primary goal is finding and fixing UX issues that hurt conversions. The AI analysis, code fix generation, and automatic PR creation are capabilities that PostHog does not offer.

Many teams use both: PostHog for product analytics and SupaStory for automated UX optimization. PostHog tells you what users do. SupaStory finds what is broken and ships the fix.
