If it's just feedback you want then you might consider creating a slideout sidebar survey using kwiksurveys (disclaimer: my company). The survey code partially preloads the form so it appears quickly when the button you attach it to is clicked.
The problem with most of the cool toys like intercom is that they don't scale for freemium SAAS companies unless you've got a ton of investor cash to burn through.
We trialed freshchat/desk for few months but their app was very buggy and in one instance actually broke our (kwiksurveys) angular backend when their site went down due to some dodgy event hijack code if I recall.
We then found helpscout which I highly recommend as a low cost intercom alternative. The helpscout UI is great and the support team was faultless. It doesn't have any of the automation of intercom so we pair it with activecampaign until I can find something better.
On a related note we're about to sign up with chargebee as chargify / recurly want to bill 6x as much for a near identical if not worse product. If it's two things I hate it's a turnover tax, and having to have a 30 minute chat with a sales consultant.
Really pleased to hear that. We love ChartJS, switching over to it from Highcharts was a breeze and I'd recommend others take a look too. From what I remember the API was nice and simple to work with.
We've been using the old version on kwiksurveys.com for a year or so now. Like many we used to use Highcharts but it had some serious performance compatibility issue with AngularJS 1.x (I'm sure they've fixed it now.)
The big problem with ChartJS was the lack of horizontal bar charts. From memory there was a 3rd party plugin for this but the author himself admitted it was a bit of a bodge.
Disappointed to see that this wasn't added to the new version. I hope this is something the team considers in the future.
I look forward to getting this up and running on our site though.
