Snip2Code is shutting down.
It has been quite a ride, since 2013 when we launched our first prototype: thanks to the effort of you guys we collected more than 3 million snippets!
We are very proud to help all our users to be more efficient in their jobs, and to be the central point to share programming knowledge for everyone.
Our basic service is free, so we always survived on our own resources to give you Snip2Code.
Unfortunately, we are no more in the financial position to sustain this effort, and therefore we are announcing here our permanent shut down,
which will take place on August 1st, 2020.
Please save your private snippets using our backup function in the settings, here.
IF YOU WANT TO SAVE SNIP2CODE, PLEASE CONSIDER DOING A DONATION!
This will allow us to pay for the servers and the infrastructure. If you want to donate, Contact Us!
