Hi HN, I built Note API Connector, a tool that lets you import and sync data from any API into Notion with just a few clicks. It's useful for building live dashboards, tracking metrics, syncing CRM data, and managing structured content inside Notion. It’s the result of several months of building, testing, and writing tutorials to make it beginner-friendly. I’d love your feedback, especially on what features or improvements you'd like to see next.

I'm Dan, and I built a CLI that lets AI agents design in Figma. What it does: 100 commands to create shapes, text, frames, components, modify styles, export assets. JSX importing that's ~100x faster than any plugin API import. Works with any LLM coding assistant. Why I built it: The official Figma MCP server can only read files. I wanted AI to actually design — create buttons, build layouts, generate entire component systems. Existing solutions were either read-only or required verbose JSON schemas that burn through tokens.

Design.MD▲111Feels a bit like Figma, but for coding agents. Instead of going back and forth with prompts, you give the agent a DESIGN.md that defines the design system up front, and it generally sticks to it when generating UI. Google Stitch seems to be moving in this direction as a standard, so we put together a small collection of DESIGN.md files based on popular web sites.
