Webix is an extremely small (about 100 kb of compressed code) and ultra fast JavaScript library for building desktop and mobile web apps based on the latest web standards (HTML5, CSS3). The library provides a rich set of cross-browser JavaScript UI widgets ranging from simple widgets, like a menu or combobox, to highly interactive charts and powerful data tables. Web apps developed with this library run correctly on multiple platforms. The server can be organized in several ways. Webix widgets are compatible with MVC frameworks (MVC.Net, Ruby on Rails, PHP, Yii).Its also possible to use Server Side Connectors (for PHP, Java, ASP.NET).In addition, developers are capable of using any server-side technology at backend, which can expose RESTfull api for data loading and data saving.

I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

  • Fellow HSP entrepreneurs, how do you manage your energy and stress?
    I force clients who want to talk to me to book a call. I use cal.com (free) and my Google Calendar (which its linked to) only allows calls on specific days/times. I have a few "Call Blocks" where they can book. That let's me do calls in a small section of my week, with ample downtime to recover the rest of the week. I'm still learning how many calls a day I can handle. Currently anything more than 2 is too much. Source: over 1 year ago
