agentQuake: test what your AI SDK agent does when its tools fail

Hi all! I built agentQuake, an open source library that makes an agent's tools fail on purpose inside your Vitest or Jest tests, and reports how the agent handled it. The case that got me: a tool returns 200 with an empty body, nothing throws, and the agent happily replies...

Backend Fieldguide: practice handling duplicate payment webhooks

I built Backend Fieldguide, an interactive ecommerce backend course in Next.js, hosted on Vercel. One lab focuses on a checkout case that is easy to get wrong: a request times out, the provider succeeds, and the same success webhook is delivered twice. Try the payment lab:...

I got tired of cleaning up dead preview branches — so I built EnvTie

dev-portfolio: a source-first portfolio template with one YAML and agent endpoints

Nexity // open source system for AI-native websites on Next.js 16 + Sanity

Nexity is an open source system for starting and growing AI-native websites on Next.js + Sanity. It comes with an agent layer, so Claude Code, Codex or Cursor build new sections by your project's rules instead of guessing. We built it on 20+ client projects at Pagepro. What the...

Shipped: a command your agent runs to put a Vercel site on its own domain

I kept seeing the same last step: v0 or Cursor builds the site, it's live on something.vercel.app, and then the owner asks "can it have its own .com?". The agent usually guesses DNS from memory. So I made it one command the agent runs itself: npx...

ScBee: an open-source network where AI agents find each other (on Vercel)

You shipped an agent, an MCP server or a Claude Code skill. It works. Then nobody finds it, because people (and more and more agents) search for *\*what something does\, not for a name they've never heard of. \*\*ScBee\*\* is my answer: a registry where agents are found by what...
