The fragmentation tax

Your stack is fragmented. Your user journey shouldn't be.

Most teams install separate SDKs for attribution, analytics, engagement, crashes, performance, and session replay — then do it a second time for the web. The result is duplicated users, inconsistent events, slower debugging, heavier apps, and disconnected teams.

01

Too many SDKs

Five vendors, five bridges, five sets of native dependencies weighing down every release.

02

Broken identity

The same person becomes three different users, so journeys never fully reconcile.

03

Delayed debugging

A crash lives in one tool, the behavior in another. Root cause takes days, not minutes.

04

Campaigns without context

Messages fire on shallow events, blind to what actually happened inside the app.

The unified journey

One user. One timeline. Every signal.

Acquisition, behavior, engagement, experience quality, and revenue arrive on a single thread — so marketing, product, and engineering finally read the same user journey instead of five partial copies.

Capabilities

Everything connected by one SDK.

Six core capability groups, one identity layer, one event schema. No exports, no reconciliation, no guesswork.

One journey, three lenses

When everything connects, every team moves faster.

The same timeline answers different questions for the people who read it.

For Marketing

Attribution you can act on

Know which campaigns bring valuable users, build audiences, trigger journeys, and retarget based on real behavior.

For Product

Behavior in full resolution

See funnels, retention, feature adoption, cohorts, and exactly where users drop off.

For Engineering

Root cause with context

Replay crashes, inspect network failures, monitor performance, and fix issues with the full session in view.

Privacy & security

Privacy-first by design.Built for sensitive apps and sites.

Sensitive data can be masked before it ever leaves the device, and access is scoped, logged, and separated by environment.

ScaleBun masks sensitive event fields on the device before securely ingesting them.
