Amplitude vs Heap

Who This Page Is For

You’re comparing these two tools because you’re deciding between:

• Manual event instrumentation (Amplitude) vs automatic capture (Heap)
• Predictive analytics (Amplitude has it, Heap doesn’t)
• Engineering capacity for tracking implementation vs no-code setup

If you need session recordings, feature flags, or self-hosting, neither tool fits well. See PostHog alternatives for bundled options.

The Core Tradeoff

Amplitude requires explicit event tracking code for every interaction you want to measure. You control exactly what’s tracked, get cleaner data, and access predictive analytics. But you need engineering resources upfront.

Heap automatically captures all user interactions without prior instrumentation. You can define events retroactively and analyze behavior you didn’t plan for. But automatic capture creates noisier data and you lose predictive capabilities.

The decision usually comes down to: Do you have engineering capacity for instrumentation? Amplitude. Do you need analytics running today without engineering work? Heap.

Quick Decision

Choose Amplitude when:

• You have engineering resources for event instrumentation
• You want predictive analytics (churn risk, conversion forecasting)
• Clean, intentional data matters more than capturing everything
• You need A/B testing (Amplitude Experiment)
• 10M free events/month covers your scale

Choose Heap when:

• You don’t have engineering resources for tracking implementation
• You need retroactive analysis (analyze events you didn’t plan for)
• Non-technical team members will define and manage events
• Getting analytics running immediately matters more than data cleanliness
• You want visual event definition without code

Consider alternatives when:

• You need session recordings alongside analytics → PostHog
• You want bundled feature flags + analytics → PostHog
• You need self-hosting → PostHog

Comparison Snapshot

The Instrumentation Question

This is the fundamental difference:

Manual instrumentation (Amplitude):

• You decide exactly what to track
• Cleaner, more intentional data
• Requires engineering work upfront
• Can’t analyze events you didn’t plan for
• Better for teams with clear analytics strategy

Automatic capture (Heap):

• Captures everything by default
• Define events retroactively without code
• Running immediately, no engineering needed
• Noisier data (captures irrelevant interactions)
• Better for teams discovering what to track

Neither is better — they serve different team contexts.

Detailed Comparison

Predictive Analytics

Amplitude: Offers predictive cohorts, conversion forecasting, and churn risk scoring. Can predict which users will convert or churn based on behavioral patterns.

Heap: No predictive capabilities. Focused on historical analysis of captured data.

Bottom line: If behavioral forecasting matters for your business, Amplitude is your only choice between these two.

---

Retroactive Analysis

Amplitude: You can only analyze events you explicitly instrumented. If you didn’t track a button click, you can’t analyze it later.

Heap: Captures all interactions. You can define an event today and analyze its historical occurrence going back to when you installed Heap.

Bottom line: If you’re unsure what to track or want flexibility to analyze unplanned events, Heap’s retroactive analysis is valuable.

---

Implementation Effort

Amplitude: Requires planning event schema, implementing tracking code, and QA for each event. Days to weeks of engineering work depending on scope.

Heap: Install one JavaScript snippet. Analytics start immediately. Define events visually without code changes.

Bottom line: If engineering capacity is limited, Heap gets you running immediately. If you have engineering resources, Amplitude’s intentional approach yields cleaner data.

---

Data Quality

Amplitude: Clean, intentional data because you control what’s tracked. Less noise, more focused analysis.

Heap: Captures everything, including irrelevant interactions. More data, but requires filtering and careful event definition to find signal.

Bottom line: Teams with clear analytics strategy prefer Amplitude’s clean data. Teams exploring prefer Heap’s completeness.

Honest Limitations

Amplitude Limitations

• Requires engineering resources for every new event
• Can’t analyze interactions you didn’t plan for
• Steep learning curve for advanced features
• No session recordings
• Pricing escalates at scale

Heap Limitations

• Automatic capture creates noisy data
• No predictive analytics
• Session replay only on enterprise plans
• Enterprise pricing is expensive
• Less depth in behavioral analysis than Amplitude

Technical Specifications

Frequently Asked Questions

Which tool is easier to implement?

Heap is faster to implement — install one snippet and it captures everything. Amplitude requires planning your event schema and implementing tracking code for each event.

I don’t have engineers to implement tracking. Which tool?

Heap. Automatic capture means non-technical team members can define events visually without code changes. Amplitude requires engineering for every tracking change.

Which tool has predictive analytics?

Amplitude. Predictive cohorts, conversion forecasting, and churn risk scoring are unique to Amplitude. Heap doesn’t offer predictive capabilities.

Can I analyze events I didn’t plan for?

Only with Heap. Its automatic capture means you can define events retroactively. Amplitude only tracks events you explicitly instrumented.

Which has the better free tier?

Amplitude offers 10M events/month free. Heap offers 10,000 sessions/month free. For most sites, Amplitude’s limit is more generous, but it depends on your traffic patterns and how sessions vs events map to your usage.

Which tool includes A/B testing?

Amplitude offers Amplitude Experiment for A/B testing. Heap does not include native experimentation.
