Auto Back Office

It's like a simplified version of PHPMaker, but way faster to install and update (they promise 30 seconds to a fully working version since you unzip the file on your server). Less functionalities for sure but ALL the important ones are available and, most of all, if you change/add a field in the DB, it updates the whole project with a single click - and if you know other HTML generators, you know what a pain is when you need to update something... Plus, some nifty features, like copy/paste the format of a field (it speeds up the configuration a lot if e.g. you have 10 fields that must be configured in the same way). It's free for commercial uses too, but if you need support there are paid plans.
