Writing Svelte with AI has made huge progress, but you still need to know what and how to set things up. At Mainmatter we wanted to put AI to the test, and we decided to do it by building an actual production application (https://dayrelay.ai) by using AI as much possible without compromising on code quality. We picked up some learnings along the way, so today we are finally releasing our Agentic Engineering with Svelte series. I've been working on this quite a bit, so I'm very excited to finally have it available. The first two episodes are out now, with more to come every Wednesday. Check out the first video and let me know what do you think about it!

A smart tool that analyzes errors, warnings, and potential issues in your Svelte projects with a single command and fixes them with a single click using AI models such as Amp, Claude Code, and Codex.

A comprehensive Svelte 5 component library that handles the complexity, so you can focus on building great products. Optimized for AI code generation and mobile-first design.

Svelte turns 10 this year — an eon in web development. After so much time, and at a moment when engineers are increasingly outsourcing the work to agents, is there anything left to do? The answer, it turns out, is a lot.

Ben Davis explores SvelteKit's 2026 relevance, showcasing its recent updates. Learn about its new features, including async SSR and remote functions, and how AI tools integrate. Discover if this framework truly surpasses others.

Most AI models struggle with Svelte 5 code. The new runes syntax and updated best practices aren't well represented in their training data. So I built SvelteBench, a benchmark to measure which LLMs write correct, modern Svelte code.
