LLMs are autocomplete for intent. As a UI engineer, that changes everything. Anywhere you can predict or complete what a user is doing, AI belongs there.

Want to see MCP and generative UI in action with Angular? GDEs Mike Ryan and Brian Love took on the Web Dev Challenge to build a party game app in just 4 hours using Hashbrown! Watch on YouTube now:youtu.be/gAeLTcxF-0o?...

Personal Software (build an app in 4 hours) · Web Dev Challenge S2.E8

Think you can top what the pros built in this episode? Join the Web Dev Challenge Hackathon and create your own MCP-powered app made for an audience of one: you. Use Postman for your chance to win $500 cash and be featured on Postman’s community and social channels. All the details, rules, and submission info: https://codetv.link/wdc/hackathon Submissions close September 22 at 11:59 PM PT — start building today. Contest open worldwide to participants 18+. By entering, you grant Postman the right to feature your submission on our website, blog, and social channels. ## The Challenge *As developers, we can often identify lots of areas in our own lives that could be improved by a custom app — if only we had the time to build them.* These days, AI coding workflows and tools like MCP servers make it much more feasible to build custom software for personal use only, so we’re challenging you to do exactly that. Wish you had an app that would turn your wifi off at 8pm so you’d actually get to bed on time? What about a chore schedule that’s exactly tailored to your family situation? Maybe a calendar that tracks only new book releases that are part of series you’re in the middle of reading. Make it practical; make it silly; whatever you do, make it personally valuable to you. ## The Tool: Postman **Your app must use Postman as part of the build.** Postman (https://codetv.link/postman) is the most popular tool out there for working with APIs. In this challenge, you’ll want to look into their suite of tools for designing and building MCP servers and agentic workflows: - MCP Servers: https://www.postman.com/explore/mcp-servers — tons of available MCP servers that you can use - Generate an MCP Server: https://www.postman.com/explore/mcp-generator — Postman has tools that allow you to generate your own MCP server from any public API - Postman AI Agent Builder: https://www.postman.com/product/ai-agent-builder/ — tools including LLM prompt testing, agent workflow designer, and tool generation - The Public API Network: https://www.postman.com/explore — this is a *huge* collection of public APIs that you can use as part of your build *THE DEVS* - Craig Dennis - Shirley Wu - Erin Mikail Staples - Elvis Kahoro - Mike Ryan - Brian Love *THE ADVISORS* Sterling Chin Jason Lengstorf ---------------------------------------------------------------------- Get early access to new videos, exclusive bonus content and other perks, and join me in building a happier, healthier, friendlier web dev community! https://codetv.dev/support ---------------------------------------------------------------------- Chapters: 0:00 In this episode... 0:30 Welcome + the challenge 0:40 Required tool + meet your advisor 4:08 Rules of the challenge + planning phase starts 4:32 Meet Team Galactic Chalkstars + their app idea 6:17 Meet Team Curly Bois + their app idea 8:01 Meet Team Tuff + their app idea 9:37 Build phase starts 11:02 Progress check ins 16:04 Late stage check ins 20:21 Team Curly Bois app demo 27:11 Team Galactic Chalkstars app demo 31:01 Team Tuff app demo 37:38 Reflections on the challenge 38:42 Outtakes and credits

Fresh out of the frying pan, we just released Hashbrown v0.3 with support for: 🦙 Open-weight models (like gpt-oss) via our new Ollama adapter 🛠️ Initial support for MCP Servers 📝 New prompt template literal function 💻 Fresh docs website 👨‍🏫 Generative UI workshops

We got Hashbrown working against gpt-oss:120b. Generative user interfaces powered by 100% open source code. No API keys, subscriptions, or external service providers in the loop.

It's been a long time since I've been up until 1:00 am on a school night hacking away at an open-source project. I seriously can't wait to show you the potatoes we've been frying at LiveLoveApp. 🥔
