PostHog vs Amplitude

Who This Page Is For

You’re comparing these two tools because you need product analytics and you’re deciding between:

• All-in-one platform (PostHog bundles analytics, feature flags, session recordings, A/B testing) vs focused analytics (Amplitude specializes in behavioral insights)
• Self-hosting option (PostHog only) vs predictive analytics (Amplitude only)
• Developer-first (PostHog) vs analyst-friendly (Amplitude)

If you’re unsure whether either fits, see PostHog alternatives or Amplitude alternatives for broader options.

The Core Tradeoff

PostHog is an all-in-one platform: analytics, feature flags, session recordings, A/B testing, and heatmaps bundled together. Open-source with self-hosting option. Developer-focused with SQL access.

Amplitude specializes in behavioral analytics with predictive insights. No feature flags, no session recordings (analytics only). Stronger for product managers and analysts who want visual interfaces without SQL.

The decision usually comes down to: Do you want everything bundled with self-hosting option? PostHog. Do you want predictive analytics with an analyst-friendly interface? Amplitude.

Quick Decision

Choose PostHog when:

• You need self-hosting for data sovereignty or compliance (only option)
• You want analytics, feature flags, session recordings, and A/B testing in one platform
• Your team is technical and comfortable with SQL queries
• You’re building with engineers who want developer-first tooling
• You want open-source with full code transparency
• You need session recordings alongside analytics

Choose Amplitude when:

• You need predictive analytics and behavioral forecasting (PostHog doesn’t offer this)
• Your team prefers visual interfaces over SQL queries
• Product managers and analysts will use it without engineering support
• You want mature enterprise features (SSO, SCIM, dedicated support)
• You need 10M free events/month (vs PostHog’s 1M on cloud)
• Self-hosting doesn’t matter to you

Consider alternatives when:

• You need automatic event capture without engineering → Heap
• You want simpler focused analytics without predictive features → Mixpanel
• You need in-app guidance alongside analytics → Pendo

Comparison Snapshot

The Bundling vs Specialization Question

This is the fundamental difference:

PostHog bundles everything:

• Event analytics ✓
• Feature flags ✓
• Session recordings ✓
• A/B testing ✓
• Heatmaps ✓
• Surveys ✓

Amplitude focuses on analytics:

• Event analytics ✓
• Predictive analytics ✓ (PostHog lacks this)
• Feature flags → Amplitude Experiment (separate product/cost)
• Session recordings → Not available
• A/B testing → Amplitude Experiment (separate product/cost)

If you need multiple features, PostHog is often simpler and cheaper. If you need predictive analytics specifically, Amplitude is the only choice between these two.

Detailed Comparison

Event Analytics

PostHog: Strong event analytics with funnels, retention, and cohort analysis. SQL access for custom queries. Developer-oriented interface.

Amplitude: Advanced behavioral analytics with predictive cohorts and lifecycle analysis. Visual interface designed for product managers. More sophisticated segmentation.

Bottom line: Both handle core analytics well. Amplitude has deeper behavioral analysis; PostHog has SQL flexibility for technical teams.

---

Predictive Analytics

PostHog: Not available. No behavioral forecasting or predictive cohorts.

Amplitude: Predicts user behavior — likelihood to convert, churn risk, feature adoption probability. Unique capability between these two.

Bottom line: If predictive analytics matters, Amplitude is your only choice. If you don’t need forecasting, this isn’t a factor.

---

Feature Flags & A/B Testing

PostHog: Included in the platform. Feature flags, percentage rollouts, A/B testing with statistical analysis. All in one place.

Amplitude: Requires Amplitude Experiment — a separate product with additional cost. Not bundled with core analytics.

Bottom line: If you need feature flags + analytics together, PostHog is simpler and cheaper. If you only need analytics, this doesn’t matter.

---

Session Recordings

PostHog: Included. Watch user sessions, see where they click, debug issues visually.

Amplitude: Not available. You’d need a separate tool (FullStory, Hotjar) for session recordings.

Bottom line: If session recordings matter, PostHog includes them. Amplitude requires a separate tool.

---

Self-Hosting & Data Sovereignty

PostHog: Full self-hosting option. Deploy on your infrastructure, own your data completely. GDPR/HIPAA compliance through data control.

Amplitude: Cloud-only. Data on Amplitude’s infrastructure (US/EU regions available). No self-hosting option.

Bottom line: If self-hosting or data sovereignty is required, PostHog is your only choice between these two.

---

User Interface & Learning Curve

PostHog: Developer-first design. SQL query access, technical documentation, API-centric approach. Engineers feel at home; non-technical users may struggle.

Amplitude: Analyst-friendly visual interface. Point-and-click chart building, less technical barrier. Product managers can self-serve without engineering help.

Bottom line: If your analytics users are engineers, PostHog fits. If product managers/analysts will use it directly, Amplitude has lower friction.

Honest Limitations

PostHog Limitations

• No predictive analytics or behavioral forecasting
• 1M events/month free on cloud (vs Amplitude’s 10M)
• Developer-focused interface less accessible for non-technical users
• Self-hosting requires infrastructure management overhead
• Younger company with evolving product (less mature than Amplitude)
• Learning curve for teams without technical background

Amplitude Limitations

• No self-hosting option
• No session recordings (need separate tool)
• Feature flags/A/B testing require separate Amplitude Experiment product
• Complex pricing that escalates at scale
• Steep learning curve for advanced features
• Enterprise focus can mean expensive for small teams

Technical Specifications

Pricing Comparison

PostHog:

• Self-hosted: Free (unlimited, you pay infrastructure)
• Cloud free tier: 1M events/month
• Cloud paid: Usage-based starting ~$0.00031/event after free tier
• All features included (no separate products)

Amplitude:

• Free tier: 10M events/month (more generous)
• Paid: Usage-based, pricing requires sales contact at scale
• Amplitude Experiment (feature flags/A/B testing): Additional cost
• Enterprise: Custom pricing with SSO, support

At 5M events/month:

• PostHog Cloud: ~$1,200/month (estimate)
• Amplitude: Free tier covers it

At 50M events/month:

• Both require enterprise/custom pricing
• PostHog self-hosted: $0 (infrastructure costs only)

Frequently Asked Questions

I need self-hosting for compliance. Which tool?

PostHog — it’s the only option between these two with self-hosting. Deploy on your infrastructure for complete data control. Amplitude is cloud-only.

I need predictive analytics to forecast user behavior. Which tool?

Amplitude — predictive cohorts and behavioral forecasting are unique to Amplitude. PostHog doesn’t offer predictive analytics.

My team is mostly product managers, not engineers. Which tool?

Amplitude — the visual interface is designed for analysts and PMs to self-serve without SQL or engineering support. PostHog is more developer-focused.

I want analytics + feature flags + session recordings in one tool. Which tool?

PostHog — everything is bundled. Amplitude requires separate products (Amplitude Experiment) for feature flags and doesn’t offer session recordings at all.

Which has the better free tier?

Amplitude offers 10M events per month free vs PostHog’s 1M on cloud. However, PostHog self-hosted is unlimited and free (you pay infrastructure). Depends on your deployment preference.

Can I migrate between them?

Not directly — event schemas differ, dashboards need recreation, and implementations require code changes. If you’re heavily invested in one, switching has significant cost.
