Maciej Zmitrukiewicz · founder, full-stack, product builder
I'm building CometWeb Insight, a platform that unifies Core Web Vitals, WCAG, and carbon footprint into one score—for teams that want to measure site quality technically, commercially, and environmentally.
Solo founder and full-stack developer. For 8 years I've built web products at the intersection of performance, accessibility, and product architecture.
Today I'm turning CometWeb from an agency into an enterprise SaaS platform for Digital Sustainability analysis—because the market needs one place instead of five tools with inconsistent results.
Concrete decisions in CometWeb Insight architecture: performance, accessibility, and carbon footprint in one system—not on a slide.
Not an ESG checkbox. Every kilobyte saved means less CO₂, a faster site, and lower running costs.
Accessibility isn't compliance bolted on at the end. It's product quality that expands reach and lowers barriers.
I prefer solid architecture over a fast demo sprint. The product should survive production, growth, and changing requirements.
Comprehensive analytics for carbon footprint, performance, and accessibility across your web stack. See your impact and optimize code for a greener web.
* Sample module scores on a project dashboard. Results depend on project, run, and analysis scope.
CometWeb is the result of an 8-year evolution: from a web agency, through AI project work, to today's enterprise SaaS platform.
Clients asked for accessibility, performance, and ecology audits—but had to use 5–7 different tools. Each showed different numbers; none delivered an actionable plan. I decided to end that standard.
CometWeb Insight is the answer: one platform combining Digital Sustainability, WCAG, Core Web Vitals, and security—with a concrete action plan, not another context-free metrics dashboard.

Three domains where I go deepest. For everything else I gladly defer to specialists—I focus energy here and reach for experts where they beat me.
Multi-agent systems for business process automation and data analysis—from prototype to production pipelines with quality controls.
Optimizing code and infrastructure for lower energy use—without sacrificing speed, SEO, or accessibility.
Scalable admin panels and B2B backends—tenants, permissions, and audit trails from day one.
Tools I reach for daily—for performance, accessibility, and maintainability, not hype.
