How is it different from other AI app builders?
Three principles, designed for small and mid-sized businesses.
Run on your own server
Apps are installed on your own server. Free yourself from cloud-vendor lock-in, service shutdowns, and data leakage worries.
AI understands your work
Just say "I want to make invoices" or "I need a booking system." Our AI agents understand requirements and build apps with the features your work needs.
One-time purchase, no monthly fees
Most apps are free; paid ones are one-time purchases. Unlike SaaS where monthly fees stack up, the longer you use it, the more economical it gets.
Set up in 4 steps.
If you have a server with PHP, you can be up and running in 15 minutes.

Who is this for?
From business efficiency to hobby apps and games. If you have an idea, AI brings it to life.
I want to build a game
Quizzes, puzzles, mini-games, leaderboards... Just tell AI "I want a game like this." No programming knowledge needed.
I want a useful utility
Budget tracker, shopping list, habit tracker, notepad... Hand off the daily "I wish I had this" tasks to AI. Simple tools come together fast.
I want to improve work efficiency
Invoicing, booking, CRM, attendance, task management... Solve the "SaaS is expensive" and "we have unique requirements" problems.
I want to use it for my hobby
Club attendance, fan-activity notes, collection management, your own recipe book... Custom specs that off-the-shelf SaaS doesn't offer.
I want learning tools
Vocabulary cards, flashcards, math drills, kanji practice, learning games for kids... Build educational apps freely.
I want to manage my own data
Worried about putting data in the cloud? Unsure how long a service will last? AI DEV TEAM apps run on your own server, for peace of mind.
I want to test an idea
For idea validation: "What if a service like this existed?" Build a prototype in 30 minutes and try it for real. Perfect for pre-launch validation.
I want to do side projects / indie dev
Portfolio sites, blogging tools, web services... Even people learning to code can ship working apps with AI as a partner.

1. Build privately
Start by building a private app tailored to your needs - specs, colors, everything is customizable.
2. List on the Marketplace
When done, choose to publish openly or list it on the Marketplace. You set the price freely.
3. Earn revenue
Credits from buyers are added to your seller balance, and you can withdraw to your bank via Stripe Connect.
※ Listing requires owning a private app and completing Stripe Connect onboarding (identity & bank account verification).
Use cases
From business to hobby. Here are some scenarios where AI DEV TEAM fits.
Frequently Asked Questions
Is there any cost?
Account signup is free. Most published apps are also free to use. Some specialized apps are paid (one-time purchase).
What kind of server does it run on?
Any server with PHP 7.4+ and MySQL/MariaDB works. This includes most shared hosting (e.g., XServer, Sakura, Lolipop in Japan), VPS, and self-hosted servers.
Can I see the source code of the apps?
Yes. Installed apps are PHP source files on your own server. You're free to modify them.
Where is data stored?
Everything is stored in the database on your own server. We never receive your data — no risk of leakage.
Can you build apps just for our company?
Yes. With "Private Requests," you can commission an app for your company only. Distribution is restricted to the owner and operator.
Will any kind of app request be accepted?
Most business-helping app requests are accepted. However, high-risk areas like medical diagnosis, financial trading, and gambling are not supported.
What are credits?
A virtual currency for private requests (your own private app development) and for premium keys to remove the "Powered by AI DEV TEAM" branding. After AI dialog finalizes the spec, the required credit count is shown for your approval before consumption. Credits do not expire.
What payment methods are accepted?
Credit card payments (VISA / MasterCard / JCB / AMEX / Diners). Payment processing is via Stripe — card details are sent directly from your browser to Stripe and never stored on our server.
How long does it take to finish?
Simple apps take 30 minutes to 1 hour; medium apps take 2–3 hours through PR creation, automated review, and deploy. Credit-using requests are prioritized.
Is the quality of AI-built apps OK?
Apps go through automated checks, a second AI review, and pre-merge verification before publishing. Even so, full operational guarantees are not possible — please verify before production use. Critical bugs can be reported via the Request Board.
Can I cancel or close my account?
There are no subscriptions, so no special cancellation procedure is needed. Account deletion can be requested via the contact form. Apps already installed remain on your own server, so you can keep using them after closing your account.
Is there support?
We accept questions and feature requests anytime through the contact form. Through the Request Board, AI also responds to technical questions.
What is the Marketplace?
A feature that lets you sell your closed apps (your original apps) to other users for cr. You set the sale price freely; after the platform fee is deducted, the remainder is added to your seller cr balance.
Can I withdraw seller cr as JPY?
Yes. Once you complete Stripe Connect identity verification (KYC), you can withdraw your seller cr balance as JPY. There is a minimum withdrawal amount; after admin review, payment is sent to your registered bank account via Stripe (typically 1–3 business days).
Who is responsible for apps sold on the Marketplace?
Apps sold on the Marketplace are individual works of their sellers. aiapps.jp only provides the platform; warranty, support, and copyright responsibilities belong to the seller. Please verify functionality and avoid third-party rights infringement before listing.
Can I get a refund for a purchased app?
Due to the nature of digital content, purchases are generally non-refundable. However, in the case of significant defects (the app does not start, or differs materially from its description), please contact us within 7 days of purchase, and we will consider it case by case.
What do I need to be a seller?
You need (1) ownership of a closed app, and (2) completed Stripe Connect onboarding (identity verification + bank account registration). Identity verification requires documents like a driver's license or My Number Card, processed directly by Stripe; aiapps.jp does not store identity verification data.
