Cookie consent that won’t slow your product down.

Developer-first consent infrastructure for software teams that ship fast.

Manage banners, preferences, regional rules, script loading, and consent records in code, without blocking scripts or black-box CMPs.

problem

Consent breaks when it lives outside the codebase.

Modern teams ship constantly. Most CMPs still assume someone will clean up consent later.

That leaves engineers managing scripts, regions, preferences, and records across vendor dashboards and one-off code. The result is slower launches, fragile tracking, and consent evidence nobody fully trusts.

Consent infrastructure developers can actually own.

Fast by default. Versioned in code. Built for teams that ship continuously.

Inth turns consent rules into product infrastructure: banners, preferences, regional logic, script loading, and consent records live close to the app instead of inside a black-box CMP.

Consent in code

Native SDKs, not tags

Regional rules

Records by default

Manage consent in code

Define banners, preference centers, regions, categories, and scripts where engineers can review and ship them.

Control when scripts run

Block analytics, pixels, and third-party tools until the user’s region and consent state allow them.

Keep records ready

Store consent events and configuration history so legal, security, and customer teams can verify what happened.

open source

It's in our DNA

The open standard for consent that puts performance and control first.

01

c15t

A headless, composable consent system that runs inside your app. Manage banners, preferences, regional rules, scripts, and consent records without black-box CMP code.

Control consent in code

Define consent behavior with versioned rules.

Keep banners, regional logic, script categories, and consent records close to your application instead of spread across vendor dashboards.

Stop bolting consent on after launch

Move consent into infrastructure developers can ship and compliance teams can verify.
