Why Legacy Data Collection Falls Short
Traditional SaaS data infrastructure often relies on fragmented, unstitched data stored in cloud warehouses or lakes.
This model not only drives up storage and processing costs, it also creates blind spots in customer journey analysis.
With cookies disappearing, gaps in attribution and tracking are widening.
Without a way to securely replay and stitch event data, SaaS platforms lose visibility into pre-consent activity—resulting in incomplete insights and ineffective optimization strategies.
Introducing Blotout’s Clickstream Replay Service
Blotout’s Clickstream Replay Service solves these challenges by:
- Capturing non-PII and consented data
- Securely holding it
- Replaying it once permissions are granted
This ensures privacy-first compliance while unlocking full-funnel visibility.
Key Advantages
- Storage efficiency — Store only data you can process, reducing overhead
- Cost efficiency — Avoid expensive processing of unneeded flat files
- Privacy-first — Data is held securely until opt-in flags are met
Who Benefits Most?
The primary ICP (Ideal Customer Profile) is SaaS companies, especially those in:
- Marketing
- Retention
These firms need post-cookie, server-side solutions that integrate with legacy infrastructure—without adding technical debt.
Any SaaS business building its data platform today should consider Clickstream Replay to avoid costly retrofitting later.
Use Case: Solving Data Capture Challenges for Retention Providers
Issue: Legacy retention providers often require PII (email, phone) before data can be captured, leaving them blind to pre-opt-in activity.
Challenge: Without pre-consent insights, providers can’t optimize customer journeys during critical early interactions.
Solution:
- Blotout securely stores event data until opt-in.
- Once consent occurs, the service stitches and replays events with timestamps.
This creates a complete customer journey—including the pre-opt-in phase.
How Clickstream Replay Works (Cloudflare-based stack)
Blotout leverages a single-tenant architecture to maximize privacy:
- 1st Party Web Server – Every customer domain gets its own compute and storage
- Cloudflare Workers – Each event is processed by a worker that manages transformation, storage, and compute
- Cloudflare R2 – Edge-based distributed storage for efficient scaling
- Cloudflare D1 – Database for profiles, IDs, and consent
Replay Workflow:
- When an event arrives, the system checks for an existing browser ID.
- If no PII is available, the event is stored anonymously.
- Once a consent event (/data) provides PII, the service:
- Replays all stored events
- Stitches them into the user profile
- Permanently deletes the anonymous logs
Why This Matters: The Post-Cookie, Privacy-First Future
With cookies vanishing and passkeys/device IDs emerging, the ability to defer processing until consent is essential.
Blotout’s approach ensures:
- Preserved customer journeys
- Reduced legal exposure
- Efficient storage and processing
This isn’t just about compliance—it’s about future-proofing SaaS data strategies in a privacy-centered world.
Competition: Where Blotout Stands Apart
- Snowplow: Developers must build replay logic themselves, slowing product development
- Rudderstack: Does not support SaaS multi-tenant replay scenarios
- Segment: Even more limited for SaaS CDP use cases
Blotout’s Clickstream Replay is purpose-built for SaaS, with multi-tenant support and automated replay functionality out of the box.

FAQs
Q1: Does Clickstream Replay store PII before consent?
A1: No — all pre-consent data is anonymous until a user explicitly opts in.
Q2: How does replay stitching work?
A2: Once PII is provided, the service replays all previously anonymous events, timestamps them, and integrates them into the user profile.
Q3: Is Clickstream Replay production-ready?
A3: Yes — the service is available today for any CDP implementation.
Q4: How is this different from Snowplow or Rudderstack?
A4: Unlike Snowplow or Rudderstack, Blotout supports SaaS multi-tenant architectures and automated replay, reducing developer workload.
