For a free host, they are extremely reliable. You wouldn't expect a company that doesn't make money from their hosting packages to offer a good support system, but they do. It all runs through the ticket system for the most part, but I've had to use it myself, and they were quick to reply to my questions. Their system allows for full backups, offer a 99% uptime, and even allow you to run cron jobs.

With their free plan, they have no advertisements, hidden fees, 1.5GB of space, and 100GB of bandwidth, as well as multiple add-on domains, SQL databases, and more! It includes a simple site builder with a light version hosting control panel, it doesn't have all the features of cPanel but gets the job done anyways. I've seen plenty of other hosts charge $5-10 a month for the same price, just not worth it. While they list a premium hosting package on their home page, which has pretty good features and pricing, it's only a link to another hosting company. 000WebHost also has a pretty good affiliate program of their own, paying you for active signups even for their free package.

One of my favorite features is the forum. As free hosting is always in demand and they offer some of the best services around, they have have hundreds of thousands of loyal users. This means they have been through most problems you could imagine and they have discussed it there for your use. If that doesn't work, just contact them via the ticket system and they'll get back to you within a few hours normally, not bad for a free host. I've had worse support from companies that I paid.

The best part about them is that the price is ZERO. No advertisements, no fees, nothing. You can use your own domain name, not a generic subdomain nobody likes, all for no cost at all. Every free host I've ever ran into besides them have some type of caveat: It's only free for a limited period, there are (or will be) advertisements, no using your domain name, or no transferring your data if you wish to leave. 000WebHost has none of these, if you want to switch to a different company, you'll be able to transfer all your files, databases, and so on, without any problem.
