[Didomi](https://docs.didomi.io/versions-and-proofs/introduction) is a hosted
consent platform with documentation for versions, proofs, consent proof reports,
and consent events APIs.

c15t is the better starting point when consent needs to affect product behavior,
backend state, scripts, and framework startup. Didomi is useful when hosted
proofs, reports, and platform workflows are the first requirement.
[CookieBench](https://cookiebench.com/) also lists c15t's Next.js and React
examples above Didomi on score, banner visibility, and network impact.

> ⚠️ **Warning:**
> Consent tooling does not guarantee legal compliance by itself. Your policies, disclosures, vendor list, regional behavior, and record-keeping still need to match your legal requirements.

## Why c15t wins here

* c15t supports durable consent records in hosted and self-hosted modes.
* c15t gives developers JavaScript, React, Next.js, scripts, backend, and CLI
  packages.
* c15t keeps server-visible consent state available to your app.
* c15t supports policy packs, script loading, iframe blocking, and network
  blocking.
* c15t lets engineering decide where consent data lives and how it integrates
  with the rest of the system.

## Comparison

|Area|c15t|Didomi|
|--|--|--|
|Primary shape|Developer-first consent platform|Hosted consent platform|
|Framework support|First-class JavaScript, React, and Next.js packages|Hosted platform APIs and snippets|
|Records/proofs|Hosted or self-hosted consent records and audit history|Consent proofs and reports|
|Script control|Loader, iframe blocker, and network blocker|Platform-driven consent workflows|
|CookieBench speed|[Score 95](https://cookiebench.com/), 89ms/148ms banner visibility, 0-byte network impact|[Score 71](https://cookiebench.com/), 250ms banner visibility, 395-byte network impact|
|Control model|Open-source packages plus hosted or self-hosted backend|SaaS dashboard and APIs|
|SSR awareness|Available through c15t framework packages|Usually outside app SSR state|

## Bottom line

Start with c15t when consent needs to be part of product behavior, backend
state, and framework startup. It gives teams a durable records path without
making a hosted platform the center of the application.
