Share your AI agent’s work with your team

Your agent generates a report, dashboard, or prototype as HTML or Markdown. display.dev turns it into a secure URL your team can open with their existing work login, comment on inline, and send back to any agent through MCP. Works with Cursor, Codex, Claude Code, and more. No viewer accounts, no seat management, no vendor lock-in.

What I'm working on

Agentic coding fundamentals for developers

It's been a while since I updated you on my new course built around Agentic Coding fundamentals. The main reason was busy times with RocketSim, WWDC, conferences, but also, I'm still learning so much.

Yet I did keep track of all my learning. I've created a diary of my own progress, which I can now use to write the course modules. Altogether, I've finished a few of the modules already.

Unlike with my concurrency course, I'm now going to only release the course when it's completely finished. Probably still in phases, so the first to join the waitlist will get the quickest access.

You might think “aren’t courses dead?” or “How will you keep the course up to date, AI is moving so fast?” and you’ll be partly right. However, I believe we lack fundamental education on how agentic coding works in general, for which this course is the answer.

It’s purposely written without focusing on a single IDE or tool. Whether you use Cursor, Claude, or Codex: the fundamentals behind it are similar. What are models? How do tokens work? What is a good prompt? From simple to advanced questions, but also the creativity of how you can use these tools to the fullest.

Stay tuned, and don’t forget to join the waitlist.
