When it comes to building a grocery delivery platform like Instacart, tools like Bubble have made it possible for makers of all backgrounds to create software without writing code. The process involves creating a user interface using Bubble's visual design tool, configuring data fields and workflows, and adding features such as searching, checkout, and order management. By leveraging Bubble's pre-built database and workflow capabilities, users can build a functional platform with minimal coding knowledge. Additionally, Bubble offers paid plans starting at $25 per month, allowing users to host their app on their own custom domain, and templates can be purchased from the community to speed up development.
