Handoff: verify you actually understood the code Claude wrote by answering a quiz. Code review was always as much about comprehension as correctness. github.com/arimet/handoff

Software that builds software is here. I call them Agentic Software Factories. Unlike Retool or Excel, they understand natural language. As a result, any company can now get tailor-made tools for ~$10k. Custom software stops being a Fortune 500 privilege. marmelab.com/blog/2026/05...

I keep seeing MCP servers get overlooked or misunderstood. I think that's a mistake: they're shaping up to be a must-have for any web service. Here's the pitch I've been making to non-tech clients. #AI #MCP marmelab.com/blog/2026/04...

Steve Blank's latest piece is a wake-up call: if your company is more than two years old, the world has shifted under your feet, and most of your founding assumptions probably aren't true anymore. steveblank.com/2026/03/17/y...

I finally managed to implement an MCP App, i.e. an interactive widget that renders inside a conversation in ChatGPT, Claude, or any other MCP-compliant agent. marmelab.com/atomic-crm/d...

How much of your project code was written by #AI? Whether to track coding agent adoption in engineering teams or security risks introduced by vibe coding, it's time to track what Claude/Cursor/Copilot/Codex do. usegitai.com

AI is getting better at coding every day. Time to diversify your skills. UX sense is hard to automate, easy to neglect. We built a free browser game to train it: spot the usability flaw in mini-apps, describe it, get scored by ML. #UX #OpenSource #AI marmelab.com/ux-quest/

"Who needs devs now that agents can do the job" reminds me of "who needs banks now that we have the blockchain". Same confusion. It was never about the technology. It's about trust. marmelab.com/blog/2026/03...

We've just releaased Shadcn Admin Kit version 1.5 with tons of new features, improvements and bug fixes. #OpenSource #React github.com/marmelab/sha...

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. #GenerativeUI #AI #MCPApps blog.modelcontextprotocol.io/posts/2026-0...

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. marmelab.com/blog/2026/01...

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. marmelab.com/blog/2026/01...

🛠️ Vous développez un agent IA ? Le prototype n’est que le début. Optimiser le coût, la rapidité et la pertinence représente 90 % du temps. Découvrez comment les outils d’évaluation peuvent simplifier ce processus dans le dernier talk de @francoisz.bsky.social!👇 @afup.org youtu.be/NjrbQ8aWDv8?...

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 marmelab.com/blog/2025/12...

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. blog.modelcontextprotocol.io/posts/2025-1...

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. marmelab.com/blog/2025/11...

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 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-...

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. #AI #DevTools #OSS #softwareengineering marmelab.com/blog/2025/10...

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. #AIEngineering #AIAgents #LLMs #SoftwareArchitecture marmelab.com/blog/2025/10...

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. #agile substack.jurgenappelo.com/p/scrum-is-d...

When teams produce code faster than they can understand it, it creates what I’ve been calling “comprehension debt”. [...] When we have to edit the code ourselves, this debt is the extra time it’s going to take us to understand it first. #AI #Coding codemanship.wordpress.com/2025/09/30/c...

Are AI coding tools going to replace developers, or supercharge them? In my opinion, AI-augmented assistants like Claude Code and Copilot Agent aren't a threat—they're an opportunity. #AI #SoftwareDevelopment #Programming marmelab.com/blog/2025/09...

I find the new Trello #UI awful. It seems I'm not the only one. Atlassian is engaged in the classic enshittification process that has plagued small apps bought by giant editors in the past 20 years. So sad. www.theregister.com/2025/08/06/t...

[Paper] Google just published a carbon footprint analysis of its flagship #AI assistant, Gemini. It's super low. They report 0.24Wh / req, about the same as my estimate (0.3Wh). In terms of CO2 equivalent, the footprint of an average Gemini request is reported at 0.03g. arxiv.org/html/2508.15...
