I love using Parabola.io platform to build sample no-code applications. This is how Parabola describes its platform on their web site:

Parabola is a drag-and-drop productivity tool that runs in your browser. We have a library of customizable, prebuilt components designed for ecommerce operations and marketing teams to pull in data, combine and transform it in bulk, and automatically take action.

I look at it as a visual, drag-and-drop serverless environment. Serverless allows you to put your application business code into small, self-contained functions. A function can call another function and so on. These functions are then executed by the platform (and you don’t need to worry about servers, resources, maintenance – all is taken care by the platform).

In Parabola you have a flow where you put various pre-build components and define the execution flow. Data from one component output is passed as input for the next component. Here one example of a Parabola flow that how to build an application to scrape data from a web site and email the results:

Every component reminds me of a small serverless function that does something specific. You go up the abstraction level (or maybe event two). The application (flow) is built using a visual and drag-and-drop approach and you don’t write any code.
