Experiments
Things I build to understand how they work. All of them are live and you can play with them.
Schedule a weather alert
A Web Push experiment: install the PWA on your phone, pick a place and a time, and an n8n workflow sends you the forecast right then.
Step 1 · on your phone
Open this page on your phone and enable it there: the notification goes to that device, not this one.
Step 2 · schedule the alert
The honest friend
That friend who looks at your website and tells you what's wrong, no sugar-coating. It may sting, but better to hear it from them than from a client, from Google or from a user who leaves and never comes back.
- 01 · Reads the public HTML of the page you give it.
- 02 · An AI (Gemini) reviews it like a friend would, not like a salesperson.
- 03 · Asks for no email or personal data: the result shows up right here.
Second brain

Frontend & UX/UI trend radar
El radar de hoy destaca la evolución de la IA aplicada en el desarrollo y la automatización, impulsando la eficiencia y la personalización. Sin embargo, no se pudieron encontrar fuentes y URLs específicas para cada tendencia con las búsquedas realizadas.
This edition is only available in Spanish for now.
IA Generativa en Desarrollo
La integración de IA generativa está optimizando la creación de código, diseño de interfaces y automatización de tareas de desarrollo.
Hiperautomatización Inteligente
Se observa una creciente tendencia hacia la automatización de procesos complejos y la orquestación de flujos de trabajo con inteligencia artificial para eficiencia operativa.
Soluciones Empresariales con ML
La aplicación de Machine Learning para análisis predictivo, personalización de experiencias y optimización de decisiones de negocio es una tendencia clave.

About this lab
I'm Richi Gallego and I've been programming for over twenty years. This site is my notebook: I build whatever makes me curious, leave it running and write down what I learn along the way.
- Everything published here works and you can try it. If it breaks, that is part of the experiment too.
- The notes and the radar are written by an AI pipeline, and every piece says so.
- Nothing is for sale here: no services, no courses, no subscriptions.
Want to tell me something?
An idea for an experiment, a bug you spotted in the lab, a note that doesn’t add up, or just a hello. I read it myself, no bots in between.
Email is optional: only add it if you want a reply.
