Cookie consent banners add 400-700KB of blocking JavaScript to your site. That's not compliance. That's a performance liability. Christopher Burns (author of c15t) broke down how to make consent a first-class part of your stack at our London Meetup. Watch →youtu.be/Lz5kmR6egRg

Performance isn't a technical detail. It's the primary lever between profit and loss at scale. And in the coming agentic AI era, it becomes even more critical — agents will choose fast sites on behalf of users.

Your site loads in 4 seconds. Your competitor's loads in 1.8. That gap costs you 4.42% fewer conversions per second. At scale, that's millions in lost revenue. Here's what before and after actually looks like 🧵

Key takeaways from @dom_sipowicz's talk at our London meetup: → You don't need to reinvent orchestration from scratch → The Vercel AI Cloud + Workflow Development Kit handles the hard parts → Production-ready agent architecture is more accessible than most teams think

"You can just ship agents." @dom_sipowicz (@vercel ) walked through architecting production-ready AI agent systems using the Vercel AI Cloud and Workflow Development Kit. Recorded live at our Frontend Forward London Meetup. Full talk: youtu.be/_TRV6fPUMJw

Long before Git, there was The Nag’s Head. Before deploy pipelines and Core Web Vitals, this Covent Garden pub was already doing what great platforms do - staying resilient, scaling with demand, and serving the people. On February 10, it’ll host our Frontend Forward meetup: created for engineers, architects, and builders working where frontend performance meets business impact. We’ll talk about: • Agentic design patterns that don’t collapse at scale • UX that includes consent without compromise • Performance as a revenue layer, not just a metric Steps from the tube. Minutes from the vibrant pull of central London. Where 1900s architecture meets 2026 frontend discourse. 📍 10 James Street, Covent Garden 🗓️ Feb 10 | 6:30PM 💬 Brought to you by Blazity, Vercel, and c15t Grab your spot: go.blazity.com/4dMlDuq photo source: TripAdvisor

Early access drops Feb 10 at our Frontend Forward meetup in London: blazity.com/event/frontend… Full public release follows.

What’s inside: – Why real-user INP > synthetic metrics – How Helly Hansen scaled Black Friday with 2× conversions, 0 downtime – Why CWV failures are org-wide, not just frontend issues – SEO-safe migration frameworks – How to fix the 20% of pages killing 80% of your revenue

Many teams are still optimizing for lab scores. Meanwhile, every 100ms of added latency can cost 1% of revenue. The issue isn’t just tooling - it’s what your org chooses to measure, who owns it, and how that impacts the bottom line.

All to deliver brand visibility reports directly in Slack - where your team already works. 📎 Repo: github.com/Blazity/ai-vis…

Tech stack includes: • Vercel Workflow: Durable orchestration of long-running jobs • AI SDK: Structured agent patterns with schema validation (Zod) • Next.js (App Router) + TypeScript • Slack Web API + Block Kit for modals, threads, and slash commands

LLMs are shaping brand perception before users even reach your platform. But many teams have no system in place to track what models actually return.

At the end of last year, we sat down with @BurnedChris, Founder of Consent.io & author of @c15tdev in Warsaw to talk: consent, performance, and developer experience. Now, that convo is live.

A study showed that almost 70% of cookie solutions were leaking consent, meaning scripts were still running even when users declined.
