Lowdefy

So I built a Wordle clone in Lowdefy. Spent enough time building dashboards and admin panels in YAML that I started wondering what else config could actually do. The whole thing is YAML, except for 22 lines of JavaScript for the colouring algorithm. The article walks through the board (two nested List blocks), the keyboard (where the on-screen buttons and the physical keys are the same config), the state model, and the one place I opted for JS and why.

The AI agent stack has stabilized. Provider, model, instructions, tools, MCP, sub-agents, approvals, lifecycle hooks. Every framework ships some version of those parts now. When patterns settle like that, they're ready to collapse into config. So that's what we did. In Lowdefy v5.3, a Lowdefy app can now run AI agents in just 30 lines of YAML 🤖 A connections entry for your provider. An agents entry with model, instructions, and a tool list. Any existing API endpoint becomes a tool by adding two fields: description and payloadSchema. Drop an AgentChat block on a page. That's the chatbot. The interesting part is what comes for free. The same routine that fires when a user clicks a button can be called by the model mid-conversation. Same auth context. Same connections. Same operators. Same secrets. Same deployment. Streaming, tool-call display, file attachments, tool approval cards, MCP servers, sub-agents, page state the agent can read and write, multi-provider routing through the Vercel AI Gateway, all in the same config shape. Big credit to Machiel van der Walt for the design work on this one. The four-layer split, connection, agent, tool, block. Simplicity that feels inevitable 🏁 https://lnkd.in/dBR_hhNy

I wrote a short article about what you can build with just 50 lines of YAML using Lowdefy. I put together three practical examples, each in 50 lines. A contact form with validation and a database save, an interactive chart with a bar/line toggle, and a searchable company directory powered by MongoDB. Have a look if you're interested, the article has the full YAML for each example along with some gifs showing them in action. https://lnkd.in/dtaZwyEV

Lowdefy 4.6 is out. 568 commits, 740 new e2e tests. Every build error now traces to the exact file and line of your YAML config. Built for humans and AI agents. Full write-up: https://lnkd.in/dQQGePfW
