builddu
Builddu is a browser-based AI app builder that converts a plain-language description into a running full-stack application. A user types a single sentence describing the app they want, and an agent writes the code, provisions a managed database, and wires up the front-end pages, leaving the user with a working project rather than a scaffold to finish by hand. The platform targets three output types: web apps, mobile apps, and Chrome extensions. Every project ships with its own managed database and a live URL, and publishing is a one-click action that can later be pointed at a custom domain. This removes the usual setup steps of boilerplate generation, database configuration, and deployment pipeline wiring. Pricing is subscription-based and metered in credits, which are consumed by builds. The Starter plan is $20/month for 100 credits (roughly 20 builds), Pro is $49/month for 300 credits (about 60 builds), and Business is $99/month for 600 credits (about 120 builds). Top-ups are available at 100 credits for $19, and new accounts receive 15 free credits with no card required.

Problem solved
Non-developers and small teams often have a clear product idea but lack the time or expertise to scaffold a full-stack application, configure a database, and set up a deployment pipeline. Builddu compresses that work into a single natural-language prompt, producing a running app with managed data storage and a live URL so the idea can be tested or shipped without an engineering setup phase.
Use cases
- Turning a one-sentence product idea into a working full-stack web app prototype
- Generating an internal tool with its own database without provisioning infrastructure
- Building a mobile version of an existing project from the same description
- Creating a Chrome extension for a browser-based workflow
- Shipping a client demo or MVP to a live URL in a single session
- Validating a SaaS concept before committing engineering resources
Audience
- Developers
- Product Managers
- Startups
- Hobbyists
- Business Users
