This issue of TLDR Dev brings you an AI context webinar, tutorials on storing HTML in favicons and adding JSON-LD to personal sites, plus deep dives on agentic AI, new developer tools (Recall, Loupe), and simplified AI agent deployments with temporary Cloudflare accounts. It also covers software buy-vs-build economics, ClickHouse’s decade of growth, common CORS pitfalls, startup funding news, and tips for getting work approved without explicit yes.

This newsletter highlights Microsoft’s new MAI-Image-2.5 model and Apple’s upgraded Image Playground, then breaks down Lovable’s self-reported growth metrics. It also links to design essays on embracing human flaws, writing decisions before mockups, and moving from rigid design systems to product context, plus a roundup of tools and case studies.
