Next time you need to build a single-page application, instead of letting your coding agent accumulate debt like crazy, point it to a well-tested and maintained open-source framework like ours!

Release v1.5.0 · marmelab/shadcn-admin-kit v1.5.0 (Feb. 2026) 🚀 Features Add <TextArrayInput> component for handling arrays of text values. Add <DateTimeInput> component for date and time input support. Add <ImageField> component for displ...

If you’re a developer, I predict that you’ll soon build less web and mobile apps and much, much more MCP Apps. Fortunately, you can continue using the language you know and love, as this standard uses the iframe as the universal UI building block.

This is a turning point: AI assistants can now become true platforms, as they are no longer limited to text only. The assistant response is a canvas where apps can draw the UI elements necessary to perform a task.

MCP Apps - Bringing UI Capabilities To MCP Clients Today, we’re announcing that MCP Apps are now live as an official MCP extension. Tools can now return interactive UI components that render directly in the conversation: dashboards, forms, visualizati...

Generative UIs are becoming a reality: both ChatGPT and Claude now support MCP Apps, a new standard that allows tools to render tables, charts, and interactive UI widgets.

A Free Laravel Admin With API Platform and React-Admin Replace Laravel Nova with a flexible admin built on open standards and open-source tools.

Laravel admins often mean Nova. It works well. But it’s paid.

There’s a free alternative.

#Laravel + #APIPlatform + #ReactAdmin = a powerful admin UI on top of your Eloquent models.

JSX instead of PHP, but more flexibility and UI power.

Agent Experience Best Practices for Coding Agent Productivity Why do coding agents shine in some projects and fail in others? This article explains how to design your codebase so agents work autonomously and effectively.

Why do coding agents work great in some projects but fail badly in others?

In my experience, the difference is rarely the agent. It’s the codebase.

Here are 40+ best practices to make coding agents faster, safer, and more productive on real-world codebases.

Transactions and RLS in Supabase Edge Functions Edge functions are a powerful way to run server-side code close to your users. But how to handle transactions and Row Level Security (RLS) in these functions?

When using a backend-as-a-service like Supabase, you can only access the database through an HTTP API. Yet it is still possible to group queries into a transaction, without compromising on security. Read on to learn more. #database #security #NodeJS #supabase

MCP Apps: Extending servers with interactive user interfaces Today we’re introducing the proposal for the MCP Apps Extension (SEP-1865) to standardize support for interactive user interfaces in the Model Context Protocol. This extension addresses one of the…

Generative UI is about letting agentic apps create user interfaces on the fly.

A new specification called MCP Apps emerges, backed by Anthropic & OpenAI, to standardize it.It's very early stage ; to get an idea of the potential, try the popular MCP UI.

Spec-Driven Development: The Waterfall Strikes Back Kiro, Spec-kit, Bmad, Tessl, and other SDD frameworks turn business analysts into Markdown reviewers. Isn't there a more agile way to use Coding Agents?

Have you come across Spec-Driven Development yet?
One AI writes the specs, another writes the code.
Sounds smart, but it's basically waterfall in disguise.
Here’s why we should stay agile instead.

Etsy's Web Performance team implemented the Speculation Rules API (SRA) to prefetch product listing pages from search results, resulting in significant performance gains (20-24% improvement in metrics like TTFB, FCP, and LCP). #WPO www.etsy.com/codeascraft/...

The Learning Loop and LLMs How continuous learning shapes effective software development with LLMs

"The ability to phrase our intent in natural language and receive working code does not replace the deeper understanding that comes from learning each language's design, constraints, and trade-offs." This analysis of #CodingAgents on #SoftwareDevelopment Is spot on. martinfowler.com/articles/llm...

Do #React Server Components Improve #Performance? When compared to a pure SPA, they reduce the LCP but don't suppress the initial interactivity gap. The main performance benefit comes from completely rewriting data fetching to be Server Components-first. www.developerway.com/posts/react-...

vibe-spec: Generate Specifications From Coding Agent Logs AI coding assistants can build software in semi-autonomy, but without specifications, projects lack functional definitions. The solution? Extract problem statements directly from conversation logs.

Using AI coding agents? You’re probably missing one thing: specs.

I built vibe-spec, a CLI that extracts requirements from your coding agent logs and generates functional specs automatically.

Why AI Agents Need to Make Mistakes Developers often try to eliminate errors from AI agents. But science shows that being wrong — within reason — is what makes intelligence adaptive.

Every developer hates AI hallucinations. But what if those “mistakes” are what make AI seem intelligent?

Neuroscience says: noise isn’t a bug — it’s the engine of adaptability.

Scrum Is Done. Finished. History. We're going to need dual-track business agility.

Scrum was revolutionary for human teams—but AI doesn't need standups, sprints, or sticky notes.

The future of work requires dual-track agility: a slow lane optimized for human collaboration & meaning, and a fast lane for AI precision & speed.
