Frequently Asked Questions


Can I hide the "Powered by AppJet" footer?

You can, though we appreciate it when developers tastefully work "Powered By AppJet" and "View Source" into their design.

The easiest way to hide the footer completely is to add the following to the bottom of your app's code:

/* appjet:css */
#appjetfooter { display: none; }

Alternatively, to gain complete control over the HTML output of the page, you can call page.setMode("plain"), and then write whatever HTML you would like.

Can I hide the source code to my app hosted on AppJet?

No, the source code to all apps is publicly visible.

We think this is of great value to the AppJet community. In return for providing developers with free hosting and storage for apps hosted on AppJet, we ask that they share their source code so that others can learn from their example.

Most app authors don't mind sharing their code. In fact, it is often a point of pride to show off the cleverness of engineering that goes into making an app work. When somebody "clones" an app, the original app is credited in the "family tree" history, reflected in the App Overview page. For example, see all the apps have cloned hello-world or apps in the directory with the most clones.

Note that unlike source code, information in persistent storage using our storage library is private, and is only accessible by developers through their application logic.

If you truly need a way to keep your source code private, you can download appjet.jar. This software lets you run a server yourself that hosts your AppJet app.

We are also planning to offer the service of hiding source code for a small fee. If you are interested in this, let us know in the forums!.

If I develop an app on AppJet, am I locked-in to AppJet hosting?

Certainly not! You can download all the software you need to host AppJet apps yourself.

Is AppJet Hosting Reliable?

Yes. We take a number of steps to ensure that apps hosted on AppJet stay up and running fast:

  • The AppJet Operations Team is on-call 24/7 in case anything goes wrong.
  • AppJet uses industrial-grade server infrastructure with redundant power supplies, redundant network interfaces, and RAIDed hard disks.
  • App code and data are fully backed up every 4 hours. We also regularly perform off-site backups.
  • The AppJet software stack was designed from the ground up to serve apps efficiently under high load.

As of August 16th, 2008, AppJet has been hosting apps for 11 months and 14 days. During that time, our uptime has exceeded 99.9%. There has been no data loss whatsoever.

Can I use a custom domain such as www.example.com, for hosting an AppJet app?
