Build an AI‑Powered WeChat Mini Program Using Free CloudBase Resources

Prerequisites

Register a WeChat Mini Program on the official platform (https://mp.weixin.qq.com/) and complete certification if you have not done so.

Step 1 – Join the AI Mini Program Growth Plan

In the Mini Program backend, open the left‑hand navigation, locate Industry Capability , and click the AI Mini Program Growth Plan entry. Click “Participate”. The button is enabled only for Mini Programs whose category is entertainment, tools, social, deep synthesis, or news and that are classified as a virtual‑tool service.

Step 2 – Claim Free Resources

After joining, the console shows the allocated resources: a 6‑month CloudBase environment, 1 billion Tencent Hunyuan 2.0 token credits, and 10 000 image‑generation quotas.

Step 3 – Connect CloudBase via CodeBuddy

Download CodeBuddy (https://www.codebuddy.ai/). In the IDE choose Configure Integration → CloudBase , log in with your WeChat account, and authorize the CloudBase environment.

Step 4 – Import the AI Mini Program Template

Create a new folder in CodeBuddy (File → New Folder).

Import the AI Mini Program template provided by the growth plan. This creates the required project structure and configuration files.

Step 5 – AI‑Assisted Development

Create a requirements.md file at the project root and describe the app in natural language (e.g., a dream‑recording and inspiration‑capture Mini Program with AI chat and summarisation).

Use the built‑in prompt examples to let the AI generate design specifications, code, and database schemas.

Save the generated files (Ctrl+S). The AI will also create Cloud Functions and CloudBase data tables.

Step 6 – Debug with WeChat Developer Tools

Download the WeChat Developer Tools (https://developers.weixin.qq.com/miniprogram/dev/devtools/download.html), add a new project using the Mini Program AppID, and select the CloudBase environment you configured. Run and debug the UI, test AI API calls, and verify database interactions.

Step 7 – Verify AI Model Usage

In the CloudBase console, check the usage statistics for Hunyuan token consumption and image‑generation quotas to ensure the AI features stay within the free limits.

Key Technical Points

The growth plan provides 6 months of CloudBase, 1 billion Hunyuan 2.0 tokens, and 10 000 image‑generation credits.

CodeBuddy integrates with CloudBase, allowing AI to generate front‑end pages, back‑end Cloud Functions, and database schemas automatically.

All generated code is saved locally; Cloud Functions and data tables are provisioned in CloudBase without manual setup.

WeChat Developer Tools are required for local testing, preview, and submission of the Mini Program.

Resource usage can be monitored in the CloudBase console to avoid exceeding the free quota.
