🔧 Workflow

The operator presets 10–20 categories of high-frequency niche utility mini program templates (such as bookkeeping, check-ins, ID photo processing, habit formation, etc.). After a user places an order and enters requirement keywords, the system calls a large model to automatically generate source code adapted to each platform's specifications and package it, then automatically submits it to the corresponding platform's open platform. The operator monitors listing review progress daily through the backend, automatically adjusts parameters for rejected applications and resubmits, and after the user pays, automatically delivers the successfully published app package and backend management permissions.

🛠 Setup Requirements

Requires basic front-end development skills and familiarity with the publishing specifications and API requirements of mini program platforms such as WeChat and Alipay. In the early stage, you can do secondary development based on open-source mini program generation frameworks, integrate large-model code generation capabilities, and connect to each platform's upload interfaces. The overall setup period is about 3–4 weeks. Initially, no complex server architecture is needed; an entry-level cloud server can support the service.

💰 Revenue

① Independent developers (main revenue): charged per use and volume, customer unit price RMB 8–12/time × daily average of about 100 publishing requests × 30 days = RMB 24,000–36,000/month; the card self-reports monthly revenue of RMB 24,000 (calculated at the lower bound of the range), and what proportion it accounts for in total revenue is not given (self-reported by the case provider, independent verification lacking); ② Subscription repurchase tier: recurring developers are charged on a subscription basis; the card's subscription user repurchase rate is about 35%; subscription pricing and its share of revenue cannot be found (case provider's statement, independent verification lacking); ③ Same-track low-price volume tier (benchmarked in the in-card case): charged at RMB 9.9/time × monthly sales of over 3,500 orders = about RMB 35,000/month; its contribution to total revenue is not separately listed (case provider data, not independently reviewed); ④ Opportunity item—content marketplace commission: commission from tool app publishers on content transactions (the open-source project version 2.1 launched a content transaction marketplace); the commission rate is undisclosed; on the industry side, a single platform adds over 200,000 new apps daily and has over 15 million cumulative apps, and how much revenue can be generated is still unclear (case provider framing, no independent verification).

💸 Cost

Server and large-model API call costs total about RMB 1,200/month, of which the large-model interface is billed by amount of generated code, with about 100,000 calls per month on average, costing about RMB 800; cloud server and object storage costs are about RMB 400.

🚀 Getting Started

Step 1: Research and reuse open-source mini program generation projects on GitHub (such as wechat-miniprogram-builder and AiToEarn), deploy locally, and run through the entire process from prompt-to-code generation to compilation and packaging. Step 2: Organize requirement templates for at least 10 categories of high-frequency niche utility tools and connect to large-model APIs to achieve batch generation. Step 3: Connect to the upload interfaces of WeChat and Alipay mini program platforms, complete automated listing process testing, and then take orders externally.

🔑 Keys to Success

✅ Familiar with the review specifications of each mini program platform, able to avoid sensitive content in advance to reduce rejection rates
✅ Provide a one-stop automated experience from generation, packaging, to listing, reducing user operation costs
✅ Build word-of-mouth in independent developer communities and reduce customer acquisition costs through referrals from existing users
✅ Continuously track updates to each platform's review rules and iterate generation templates to adapt to new specifications

⚠️ 风险

⚠️ Major platforms are tightening reviews of batch, low-quality, homogeneous applications, and may directly ban personal publishing interfaces
⚠️ After automated generation capabilities become widespread, services become severely homogenized, making it easy to fall into price wars
⚠️ If generated tool applications have functional defects or compliance issues, they may trigger user complaints and lead to platform accountability

📌 Real Cases

📌 1. Independent developer Lin built a micro-app listing service based on similar logic; in the first half of 2025, he published over 2,000 mini programs for 120 independent developers, with average monthly revenue of RMB 21,000;
📌 2. A Taobao store offers an 'AI-generated mini program agency listing' service at RMB 9.9/time, with monthly sales of over 3,500 orders and monthly revenue of over RMB 30,000;
📌 3. The open-source project AiToEarn provides multi-platform automatic distribution capabilities, verifying the market potential of such tools; a single developer used it to publish over 300 tool applications per month on autopilot.
