The Manila Observatory is a private non-stock, non-profit, scientific research institution established in 1865 by the Jesuit mission in the Philippines. With Federico Faura at its inception, it was engaged in the systematic observation of Philippine weather. At the turn of the 21st century, the Observatory finds itself at the nexus of global concerns for environment and development.

The Manila Observatory website is primarily an online “company brochure”. However, the website also contains a lot of up-to-date information regarding the local weather and earthquakes. To update itself, the website was programmed to communicate with other computers that process data coming in from the Observatory's remote monitoring stations. The website takes advantage of popular web technologies such as Twitter and Google Maps to present this dynamically-generated information.

The website also has a catalogue of scholarly publications that the general public can download.

The website is an implementation of SaWALi, that works in conjunction with other custom-made web and server applications.
