I found a really useful resource recently that I think every developer should know about: free-for.dev.
It is a curated list of services that offer free tiers, and it covers almost everything you might need, including cloud platforms, databases, authentication, monitoring, email services, and more.
One common problem when building side projects is not always coding. It is choosing tools. You start searching for hosting or a database, then suddenly you are comparing pricing, limits, and plans instead of actually building.
That is why a resource like this is so helpful. Instead of spending time hunting across product pages, you can quickly see what is available and move on to the work that actually matters.
For learning and experimenting, it is especially useful. You can try more ideas, build more projects, and focus on development instead of cost.
If you build side projects regularly, this is definitely worth bookmarking.
