  • Always-on public URL

    Our users love the public URL feature of SourceLair. It lets them publish and showcase their work in progress in seconds to anyone they like.

    After several hours of inactivity we are hibernating the server behind your public URL, in order to keep the load of our infrastructure in reasonable levels. This led to uncomfortable 502 Bad Gateway error pages, when people visited the public URL of a hibernated project's server. The error page would stay there until the owner of the public URL's project started working on it again in SourceLair.

    Starting today your public URL will be always available, for every visitor. In case your server has been hibernated, an informative page will show up that will take care of waking up your server automatically in just a few seconds, thus making it again available.

    Always on public URL

    All you have to do is develop your web application at and share your public URL with the people you want to, while being sure that your app will be available.

  • Start where you left off

    After introducing the persistent Terminal, today we are shipping persistence of your whole workspace.

    From now on, everytime you log in, your previous workspace will be restored almost instantly. All the editor tabs from your previous working session will reopen and you'll be able to pick up exactly where you left off!

    Try it out now. Just go to, start working on your project, refresh your page and watch as your workspace is restored.

  • Know when you are offline

    Despite the fact that we have internet access almost every time we use our computers, some times internet connection gets lost unexpectedly. And if internet connection disappears without noticing, we may experience unfortunate events.

    Starting today SourceLair will let you know when you are offline and protect you from such cases. When your browser loses connection, a dialog will show up acknowledging you about the lack of connectivity. This dialog will vanish automatically when your internet connection recovers.

    All you have to do is go to and continue working, while feeling sure that you won't mess up your work-in-progress by mistake.

  • Web Development: From zero to professional

    We want to help our users to improve their knowledge and become better and better in development.

    Having this in our minds, we created a brand new, well-explained, yet compact guide in order to help our users set up a professional workflow for web development.

    This guide is really special because it was crafted to make people with very basic web development knowledge, start working like a professional. It covers the flow from starting a website, to deploying it to a server and can be followed from a novice to an experienced web developer.

    So start your HTML website from SourceLair using Git and deploy to your server easier than ever.
