Material UI
Ready-to-use foundational React components, free forever. It includes Material UI, which implements Google's Material Design.
MUI is the OG of UI component libraries. They’ve been at the top back since when Bootstrap was a contender and are still maintaining a top spot in the era of Tailwind and other UI libraries. With more than 95k GitHub stars (and counting), and top companies using it in production, I’d say this is the open-source React component library with the most stars. MUI also has paid components available for enterprise users.

storybook
Storybook is the industry standard workshop for building, documenting, and testing UI components in isolation
📚 4. Use Storybook (Seriously) If you’re not using Storybook for UI development, now is the time. It isolates your components from the app, which means:
-
mermaid
Generation of diagrams like flowcharts or sequence diagrams from text in a similar manner as markdown
Once all the important tech is in-place to enable software delivery, the necessary augmentation is what comes next. Documentation is a non-negotiable demand of the craft, and tools like PlantUML and Mermaid have enabled maintenance of Documentation as Code (Docs as Code).

Bun is still a toddler: it's not ready for primetime.
Simple example: you know how at the command line you can type "npm run", and then type a character or two, hit tab, and the appropriate script from your `package.json` will autocomplete? And if you keep going (eg. "npm run knex") you can do the same thing to autocomplete arguments?
Bun still hasn't figured out how to do that (https://github.com/oven-sh/bun/issues/6037). I really liked using bun when I played around with it, but if they can't handle something as simple as Bash completions, they're not ready for the big leagues.

Nest
A progressive Node.js framework for building efficient, scalable, and enterprise-grade server-side applications with TypeScript/JavaScript 🚀
Project mention: From TypeScript to SQL: Automatically Granting DB Permissions Without Losing Your Mind | dev.to | 2025-08-12At IVAO, we partially follow micro-services best practices. This means each business group (e.g., Flight tracking, Flight planning, Air Traffic controlling, Training) has its own NestJS API and ReactJS frontend. But we took a shortcut on the DB side, as we have quite some references across systems, especially for user IDs, airports, etc... We decided to have a single MariaDB instance while having a dedicated logical database for each API, so we still have a separation of concerns but we can guarantee data integrity with foreign keys across those databases.

Lobe Chat
LobeChat is a open-source, extensible (Function Calling), high-performance chatbot framework.It supports one-click free deployment of your private ChatGPT/LLM web application.
Project mention: MCP Proxy Pattern: Secure, Retrieval-First Tool Routing for Agents | dev.to | 2025-08-20It’s worth noting that the ecosystem of MCP servers is expanding very rapidly. There are already thousands of MCP servers available, covering everything from Slack bots to web scraping to code execution. Community-driven directories like Pulse MCP, Glama MCP server directory, Smithery, and LobeHub marketplace (see the LobeHub MCP index) list thousands of servers and provide usage stats. Anthropic and others are working on an official MCP registry to standardize how agents discover and install these servers dynamically. In short, the raw material (tools) is out there; the challenge is connecting the right tool at the right time. A middleware like MCPProxy, especially paired with an intelligent registry search, could let agents tap into this vast toolbox on demand without human micromanagement.
