Diet: A Free and Open-Source AI App Builder
Diet is presented as a free and open-source alternative to full-stack developer tools like Lovable, v0ero Bolt New, and Replit, which often have features locked behind paywalls. Diet offers similar functionality for building apps locally using AI agents, but without the subscription costs. It operates under the Apache 2.0 license and provides a one-click installer for macOS and Windows. A key advantage is its privacy, speed, and integration capabilities, including Superbase and GitHub.
Setting Up and Using Diet
- Installation: Download the application.
- Prerequisites: Install Node.js, which is essential for Diet to function.
- AI Model Configuration: Set up the AI model of choice, using either a Google Gemini API key (free tier available) or keys from other providers. Custom providers, such as locally hosted models via Ollama, can also be integrated by specifying the API base URL. The presenter uses Enthropic's Claude-3 Sonnet model.
- Prompting: Use natural language prompts to build apps. Examples given include building a 3D portfolio viewer and a personal finance dashboard. Diet supports importing prompts and apps from previous generations.
- Build Modes: Choose between "Auto" mode for autonomous code generation or "Ask" mode for Q&A with the AI agent. A human-in-the-loop option is available for refining each step.
- Component Editing: Use the "select component" feature to highlight and edit specific elements within the generated app.
Model Options and API Keys
Diet allows users to bring their own API keys for different AI models. Several free options are highlighted:
- GLM 4.5 & Moonshot AI Kim K2: Accessible for free through Open Router using a free API. The presenter notes that these models have agentic coding capabilities comparable to Claude or Sonnet.
- Gemini 2.5 Pro: Provides access to a free tier, although it may be rate-limited.
Users with sufficient compute can also locally host models using Ollama and connect them to Diet.
Features and Integrations
- Code Visualization: Diet allows users to visualize the generated code and its base structure, facilitating installation and configuration of the backend.
- Environment Variables: Users can configure environment variables within Diet.
- One-Click Deployment: Direct deployment to GitHub or Vercel is supported.
- Templates: Diet includes a few templates, such as React.js, Next.js, and Angular, similar to Firebase Studio.
- Superbase Integration Facilitates integration with Superbase.
- GitHub Integration Facilitates integration with GitHub.
KD: Design Platform (Sponsored Segment)
KD is presented as a design platform for creating graphics, logos, and merch. Key features highlighted include:
- Advanced Text Editing: Allows styling of individual letters within a single text box, including adjustments to font size, color, letter spacing, line height, ligatures, and weight.
- KD Flows: An AI-powered design prompt feature that provides design concepts with a single click.
A promo code for 25% off the first month of a pro plan is offered.
Example Applications
- Landing Page: A basic landing page is generated to demonstrate Diet's component-based building approach. The AI builds individual components (CTA, testimonials, features) which can then be approved and visualized.
- Personal Finance Dashboard: Diet rapidly generates a personal finance dashboard with an expense breakdown graph, pie chart, recent transactions, and budget progress to showcase the platform's prototyping capabilities.
Main Takeaways
Diet is a promising local, open-source, and free alternative to paid full-stack developer tools. It offers a user-friendly interface, supports various AI models, and provides useful integrations for rapid prototyping and component building. While not intended for building full-scale applications, Diet is a valuable tool for developers looking to experiment with AI-assisted development without incurring subscription costs. The video recommends sticking with the free version.
