JetPack , the megaplugin Automattic has many virtues, but a great disadvantage, that some do not like anything, is the dependence on WordPress.com , you have to open an account if or to use any plugin module.
This disadvantage for some, but not for others. I mean, anyone who just arrived to find WordPress a great ally in JetPack , which after passing through register on WordPress.com, you make life easier by offering a good amount of functionality by installing a single plugin.
For others, the fact of requiring registration, or for some services to be connected with WordPress.com to run, is just the opposite.
Well, if you like any of the modules JetPack but do not want this dependency there are options ...
One option is to use the Jetpack modules that can be used independently, without installing the full plugin for this WPsites uploaded them for download alone, are these:
Contact forms JetPack
Jetpack social buttons to share
Any other option is, for example, you can use the Jetpack Carousel without a plugin that does the same function but without the megaplugin, or install on your own ShareDaddy , which is actually the plugin " father "of the" Share " of Jetpack.
And so far already, if you know of any replacement plugin modules JetPack you tell us in comments.
