Software that
ships itself

Infrastructure for Adaptive Software.

Reshapes around every user, continuously.

From the least worst version for everyone to the best version for anyone.

Most apps freeze on release. Differ keeps yours adapting — per user, automatically, inside boundaries you set.

How it works

01

Import

Connect a GitHub repo. Differ assesses fit, clones it, and runs it on a managed runtime. You set the guardrails: what's in scope to adapt and what stays off-limits.

02

Observe

Every user gets their own anchor. Differ watches behavior: clicks, navigation, flows repeated, and clusters it into signal.

03

Adapt

When a signal is real and within the bounds you set, an agent proposes a change with rationale and cited evidence. Schema, auth, and runtime shape are off-limits by default.

04

Diverge & deploy

Differ commits the change to a per-user version of your app, builds it, boots it, and routes that user to it. Your stem stays untouched.

One stem. Many lives.

Your app stays canonical in your repo. Differ derives an adapted version per user — keeping the stem untouched.

The baseline

Your app, exactly as it is in your repo. Differ calls it the stem. It never changes.

The adapted versions

The same app — but it learns from real usage and adapts its UI to each person using it.
