Overview
c15t is an open source consent management framework for web apps. It ships React and Next.js components — ConsentManagerProvider, ConsentBanner and ConsentDialog — plus a headless core for other frameworks, and gates third-party scripts such as Meta Pixel behind consent. It runs against a hosted backend or self-hosted, and a CLI scaffolds an initial setup.

- Self-hostedCLI
Strengths and trade-offs
Strengths
- Headless core works with React, Vue, Svelte, Angular and others
- Open source, with hosted and self-hosted deployment modes
- Built-in i18n and geo rules for 15+ privacy jurisdictions
- CLI scaffolds a banner; styling uses your own CSS and tokens

How this score is made up
Each dimension is scored out of 100 and combined into the headline score using fixed weights.
MCP support
Whether an agent can drive the product through the Model Context Protocol, and how much setup that takes.
API quality
Public API surface: machine-readable spec, official SDKs, documented auth, errors, rate limits and versioning.
Documentation
Publicly reachable docs — coverage, freshness, code samples and machine readability.
Agent friendliness
How readable the site is to an automated client: llms.txt, structured data, server-rendered content, crawler access.
Changelog
A public, dated record of what shipped and when — the clearest signal that a product is still alive.
Marketing site structure
Whether the site answers a buyer's questions: clear positioning, the pages that matter, and accessibility.
Page speed
How fast the site loads for real visitors: Chrome UX Report 75th-percentile LCP, INP and CLS, with a Lighthouse mobile run standing in where a site has too little traffic for field data.
Operational trust
Status page and incident history, security disclosure, compliance and data-processing documentation.
Measured, but not part of the score
Useful to know, but not a mark for or against the product — so these do not affect the ranking.
Openness
Source availability, self-hosting, data export and open standards. Scored and shown, but not part of the composite — paid SaaS is not worse for being paid SaaS.
Maintenance
Release cadence and repository activity. Scored and shown, but not part of the composite — it is only measurable for open repositories.
