    Products & Services

    4
    ECP Specification

    An open standard for agent-vs-browser content negotiation using ecp.json and AgentWelcome.md.

    ecp.dev

    Hosted ECP Context Servers for websites to host their AgentWelcome.md content with Cloudflare-backed delivery.

    Codebase Observer

    A related semantic codebase analysis tool that generates architectural blueprints (ECP-enabled).

    ecptest.com

    A testing tool to verify ECP implementation on any URL.

    Market Position

    ECP positions itself as a 'web-native' alternative to separate agentic infrastructure, using standard HTTP headers to enable a semantic layer without changing URLs or authorities.

    Leadership

    Founders

    JD

    Joseph D.

    Software Architect; creator of the Evōk Semantic Coding Engine and Codebase Observer; built digital twins for codebases using provably correct AI engineering.

    Executive Team

    JD

    Joseph D.

    Software Architect / Founder

    Lead architect of ECP and Evōk Semantic Coding Engine.

    Founding Story

    Created to solve the 'AI readability' problem of the modern web. ECP leverages the existing RFC 2616 HTTP content negotiation spec (from 1999) to distinguish between browsers and agents at request time, allowing sites to remain canonical while being optimized for two different audiences.
