How does ClickStream compare to Amplitude?

ClickStream provides first-party identity resolution with 365-day cookie persistence, edge-computed behavioral intelligence, and full data ownership — areas where Amplitude relies on third-party identity, cloud-based processing, and retains control over your data storage and export options.

Does Amplitude support first-party identity resolution?

Amplitude uses device IDs and user IDs for identity but does not provide first-party cookie infrastructure with server-side persistence. ClickStream's proxy iframe architecture achieves 365-day cookie persistence across all browsers, including Safari ITP-restricted environments.

Which is better for behavioral analytics, ClickStream or Amplitude?

ClickStream runs 26 behavioral scoring models at the edge in under 3ms for real-time personalization. Amplitude offers behavioral analytics through cloud-based queries that introduce latency, making real-time scoring and in-session personalization significantly slower.

Platform Scope: Funnel Analysis vs. Full Behavioral Intelligence

The fundamental difference between Amplitude and ClickStream is scope. They solve different problems and serve different needs -- though there is overlap in the middle.

Amplitude: Product Analytics Focused

Amplitude was built as a product analytics tool. Its core strengths are:

Funnel analysis -- multi-step conversion funnels with drop-off analysis and conversion drivers
Cohort analysis -- behavioral cohorts based on event sequences and user properties
Retention analysis -- day-N retention curves with cohort comparison
User journey mapping -- pathfinder and journey analysis for in-product flows
Experimentation -- built-in A/B testing with statistical significance

These are powerful capabilities for product teams optimizing in-product experiences. However, Amplitude's scope is primarily post-login product analytics. It doesn't address the broader marketing analytics, identity resolution, or behavioral intelligence challenges that modern data teams face.

: Identity + Behavior + Intelligence

ClickStream starts earlier in the journey (anonymous visitors) and goes deeper (behavioral scoring). Its scope encompasses:

Identity resolution -- identifying industry-leading of all visitors, not just logged-in users, from their first touch
Behavioral scoring -- 26 models computed in real-time at the edge for every interaction
Full-journey analytics -- from first anonymous visit through conversion and retention, all connected by identity graph
Real-time intelligence -- sub-second insights delivered via WebSocket for personalization and decisioning
Attribution -- multi-touch attribution with transparent algorithms across all channels
Data portability -- export your full dataset as Parquet anytime with zero vendor lock-in

Where Amplitude asks "What did users do in the product?", ClickStream asks "Who is this person, what do they want, and what should we do about it?"

Identity Resolution: Login-Dependent vs. First-Party Cookie Architecture

Amplitude's Identity Model

Amplitude's identity resolution is fundamentally login-dependent. The platform assigns an anonymous device ID on first visit, but meaningful identity stitching only occurs when a user logs in and you pass a user ID through the SDK. This means:

Anonymous visitors are tracked by device but not reliably identified across sessions
Cross-device identity requires the same user to log in on each device
The gap between anonymous and known is bridged only by login events
For websites with low login rates, the majority of visitor activity is unresolved
Pre-login behavior is often lost or disconnected from the eventual user profile

's First-Party Approach

ClickStream identifies visitors from their first interaction, before any login occurs. The first-party cookie architecture combined with multi-signal device signatureing and behavioral pattern matching means:

industry-leading identification rate for all visitors, including those who never log in
Cross-session persistence via first-party cookies that browsers treat as legitimate site functionality
Cross-device resolution through behavioral patterns and shared signals, not just login events
Pre-login attribution -- every anonymous touchpoint is connected to the eventual identity graph
No SDK dependency -- identity resolution works from a single script deployment, no code changes needed

For marketing and growth teams, this difference is transformative. Instead of analyzing the small fraction of visitors who log in, ClickStream provides intelligence on your entire audience.

Real-Time Capabilities: Minutes vs. Milliseconds

Amplitude's Processing Pipeline

Amplitude processes events in near-real-time, with most events available for analysis within a few minutes. This is fast by traditional standards, but it is not true real-time. The delay means:

You cannot personalize the current session based on behavioral analysis
Alert triggers have inherent latency -- by the time you know a user is churning, they may have already left
Campaign monitoring has a minutes-long blind spot after changes
High-volume event streams may experience additional queuing delay

's Edge-Computed Real-Time

ClickStream processes events at the Cloudflare edge with sub-second latency. Events are scored, enriched, and available via WebSocket in milliseconds:

In-session personalization -- use real-time behavioral scores to adapt the experience while the visitor is still on the page
Instant alerting -- trigger notifications the moment behavioral thresholds are crossed
Live dashboards -- watch visitor behavior unfold in true real-time, not minutes-delayed approximations
Edge processing -- because computation happens at the edge, there is no centralized processing bottleneck. Each visitor's events are scored at the nearest Cloudflare POP.

Cost at Scale: Per-MTU Pricing vs. Usage-Based

Amplitude's Per-MTU Model

Amplitude prices primarily on Monthly Tracked Users (MTUs). This model has several implications for growing businesses:

Free tier: Up to 100K MTUs with limited features (no behavioral cohorts, limited data history)
Growth tier: Per-MTU pricing that seems reasonable at lower volumes but scales non-linearly
Enterprise tier: Custom pricing, typically $50,000-$200,000+/year for high-traffic applications
MTU counts can be unpredictable, especially for high-traffic websites vs. apps
Anonymous visitors still count as MTUs, driving up costs even without identity resolution
Feature gating means you pay more not just for volume but for capabilities like behavioral cohorts and predictive analytics

's Usage-Based Model

ClickStream uses usage-based pricing built on Cloudflare's cost-efficient infrastructure:

Pay for compute (Cloudflare Workers requests) and storage (R2), not per user
All features included at every tier -- identity resolution, all 26 scoring models, real-time WebSocket, full attribution
No feature gating -- you don't pay extra to unlock behavioral intelligence or advanced analytics
Costs scale linearly with traffic, not with user counts that can spike unpredictably
Zero egress fees on data exports, so accessing your data in Parquet format is always free
For high-traffic sites, ClickStream typically costs a fraction of equivalent Amplitude plans

Data Ownership: Vendor Infrastructure vs. Full Export Freedom

Amplitude: Their Infrastructure

Amplitude stores and processes your data on their infrastructure. While they provide export capabilities and API access, the fundamental reality is:

Your data lives on Amplitude's servers, managed by their team
Data export is available but requires their pipeline and format
If you leave Amplitude, migrating historical data is complex and often incomplete
Data retention is tied to your contract terms
No option to bring your own storage or choose data residency

: Your Data, Always Exportable

ClickStream stores your data securely on managed R2 infrastructure and gives you full export freedom:

Full data portability -- export your complete dataset as standard Apache Parquet files at any time
Zero egress fees -- export and access your data from any tool without transfer costs
Standard formats -- Parquet files work with any analytics tool, data warehouse, or ML pipeline
No vendor lock-in -- if you ever switch analytics platforms, export your full history in standard formats
Compliance control -- data residency options to meet GDPR, CCPA, and other regulatory requirements
