Apologies, but automatic signup for RateLim.it API keys is closed.
Ratelim.it has been fabulous (and well named) but we aimed too small. The fact is that off-the-shelf APIs is a really good idea and for more than just rate limits. With this in mind we're re-branding to Prefab.cloud and doing an overhaul of some of the underlying tech so that we can more quickly support language alternatives to Ruby and Java.
Existing customers will have a very easy migration path, but while things are in flux we are going to limit new signups so as not to give you a disjointed experience.
So! Feel free to fill out this form, I'd love to speak with you about your needs and ETA for when we can solve them. Once inside however, you won't be able to sign up for an actual API key.
