Micro-frontends promise to help teams scale development, but AWS Principal Architect Luca Mezzalira has seen some succeed and some just fall apart. In this conversation, he shares what he's learned from years of implementation work at companies like DAZN and through consulting with Fortune 500 organizations.
Luca explains why micro-frontends are fundamentally different from components—something many teams get wrong from the start. He discusses the common pitfalls he encounters: teams treating them like distributed components, sharing state across boundaries, and copying architectures from companies with completely different constraints and resources.
The discussion covers practical implementation details—from communication patterns and tooling strategies to when approaches like iframes actually make sense. Luca also touches on newer developments in server-side rendering and how they're changing the micro-frontend landscape.
This isn't about micro-frontends being good or bad, but about understanding when and how to use them appropriately. Luca emphasizes the importance of context and organizational design in making these architectural decisions work.

Why CSS is Now the Fastest-Moving Space in Web Development (with Una Kravets)


While everyone's talking about AI disrupting development, Una Kravets from Google Chrome reveals a surprising twist: CSS has quietly become the fastest-evolving part of web development. In this conversation, Una breaks down how features that required months of JavaScript engineering are now landing as native platform capabilities. Think customizable dropdowns, anchor positioning, and scroll-driven animations. She shares insights from working directly with Chromium engineers and explains why senior developer expertise is becoming more valuable than ever, even as AI lowers the barrier to building applications.
Una walks through her process for identifying platform gaps and working with standards bodies like Open UI. She also tackles the unique challenge of scaling web platform knowledge in an AI-driven development landscape, sharing her mixed feelings about AI's current applications. From her success building Chrome extensions with Gemini to her frustration with chat-based customer service, Una argues for using AI where it makes sense while maintaining the human elements that make the web engaging. Whether you're skeptical about AI's role in development or curious about the cutting-edge of CSS, this conversation offers a grounded yet forward-thinking perspective on the future of web development.

What does it take to build a web browser when everyone says it's impossible? In this episode, we sit down with Andreas Kling, the engineer behind Ladybird—the only major browser project that doesn't take money from Google.
Andreas breaks down a uncomfortable truth: Google funds every major browser through search deals. Chrome, Firefox, Safari—they're all dependent on Google's advertising revenue. Ladybird is building the first truly independent alternative since the early Firefox days.
We dive deep into the technical challenges of implementing web standards from scratch, why their 700,000 lines of code can compete with Chrome's 100+ million, and how they're making browser code that actually mirrors the specifications. Andreas reveals why they switched from UTF-8 to UTF-16, why they didn't choose Rust, and how they handle the constant evolution of living web standards.
From the "draw the owl" problem of CSS specifications to building a sustainable nonprofit model with sponsors like Shopify, Andreas shares the engineering and business decisions behind their ambitious timeline: alpha in 2026, beta in 2027, and v1.0 by 2028.
