Build in the browser
Bolt, developed by StackBlitz, turns written instructions into websites and applications. It runs in a browser and provides a code view alongside conversational editing.
A suitable starting point
Our suggested use is a small interactive page whose behavior matters as much as its appearance. Define the inputs, the calculation or decision, and the output before choosing a visual style. That gives you something concrete to check.
A useful first task
Try a delivery-cost calculator using fictional rules: a fixed base fee plus a surcharge above a weight threshold. Ask Bolt to show the calculation, handle an empty field and explain invalid input. Supply examples for zero weight, the threshold and a value just above it. Compare every result with your own arithmetic.
What to check
Bolt’s app-building environment and the finished app are separate things to evaluate. Check the supported technology choices and the ongoing hosting or database requirements. Make sure you can retrieve the code and understand how the deployed version will be updated.
