As opposed to most famous no-code tools, we don't do any nested-based editing (e.g. tree structure like Webflow - which is an amazing tool, but is basically a visual HTML editor requiring almost the same skills). Instead, we have free canvas-based editing, so we let designers freely iterate as they do with prototyping tools like Figma/AdobeXD/Sketch/etc.
Our visual interface builder lets you add controls using "springs". This is a kind of constraint layout (like XCode/Android studio does) without Cassowary solver (which means more tolerance to inconsistencies). This idea actually came from a master thesis project with my girlfriend where we created methods to simulate elastic material deformations. Then I realized that those abstractions (elastic springs) are easier to understand than the flexbox/grid/box model for UI layout.
Abstra is great for companies that want to make MVPs in production, learn with real data and move faster. We already have a few companies using Abstra. One of them is Stone (Nasdaq: STNE), which uses us to build internal tools faster than coding by hand. Examples of what people have built so far include a customer support portal, a field sales collaborative notes app, financial controls, timesheets, an employee evaluation tool, and a student enrollment control.
