What's H2O?
H2O is programming made for the web.

What's it like?
H2O is English-like. If you know some Perl, VB, ASP, or PhP you'll be immediately productive in H2O. It runs on Linux, Mac, Unix, and Windows.

How do I try it?
Download H2O for free. Get it from hosting providers. Or buy on-line.

Where does H2O come from?
The language was invented by Aestiva. H2O stands for:
   HTML with
   HTML/OS
   Overlays.

 
 
The H2O Family
Comparison between H2O engines.

The H2O family includes three engines; H2O, H2O Titanium, and HTML/OS. The differences between engines is a matter of capacity and customer support.

H2O is the entry-level product. It's free. The product meets the needs of small businesses, students, and people trying H2O for the first time. To download, click here.

H2O Titanium is a professional version of H2O. It includes more database capacity and support for secure (HTTPS) servers. This version is for active users of H2O and can be purchased using the H2O Upgrade Icon* bundled with H2O.

HTML/OS is H2O at its best. This version includes a special session optimizer so it can support thousands of users per day. The database engine supports data tables of up to 99 million records. The version includes on-line and voice support.

HTML/OS Professional may be purchased at www.aestiva.com/htmlos.
