addtothese is a curated collection of tools, libraries and free resources for people who build software: developers, designers, and the many people who are quietly both.
How things get on a list
There are three rules, and they are the whole editorial policy. First, I have to have used the tool, or have a specific reason to recommend it. Second, nobody pays to appear here: there are no sponsored placements, no paid reviews and no affiliate deals shaping the order. Third, lists get updated when reality changes, and entries get removed when a tool stops deserving its place.
Who maintains it
My name is Ferran Suils. I am a full-stack developer, DevOps engineer and UX/UI designer based in Barcelona, and I work as a freelance on web applications, APIs, infrastructure and interfaces.
Everything recommended here comes out of that work: streaming platforms, ticketing systems, dashboards, design systems and the infrastructure that keeps them running. That is the only qualification this site claims, and it is also why the lists are short.
Available in twenty languages
Every list on this site is published in twenty languages. Translations are reviewed for the terms that matter, but if you find something that reads wrong in yours, tell me and I will fix it.
