Really small front-end framework. I used React, and Angular 10, but if you are interested in developing really fast loading websites, this is the framework to go. At PS2PDF.com we use PreactJS and able to achive 90+ on PageSpeed without much effort on optimization, https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Fwww.ps2pdf.com%2Fvideo-compressor&hl=en_GB&tab=desktop

Xenmaster's 2026 Front-End Web Development Catalog

This list is an update to the list I created seven years ago https://alternativeto.net/lists/8008/front-end-development/. The web and development has changed a lot since then and rather than re-write history, decided to create a new list based on current patters and shifts in enterprise environments. These details are based on both what I've seen in the professional world as well as for hobbyists and web development enthusiasts who run their own projects. In addition to consulting the documentation for each of the tools below, I'd like to shout out the following projects which also played a big part in informing the overall structure of this list: Jeff Delaney's 100 Second Videos: https://www.youtube.com/@Fireship Kamran Ahmed's Roadmaps: https://roadmap.sh Devographics's State of JavaScript 2025 Survey: https://2025.stateofjs.com/en-US Note that I don't plan on covering anything AI related for the development process. If I did, the list would have two items: Claude-Code, and Sonnet. Using these tools, it's easy to build out slop that won't work reliably which you don't understand and can't maintain.
