Mini Apps, or tApps, which are actually the same, have been around for a while, and there are already plenty of use cases. They’re a great way to enhance the functionality of an existing product or help businesses connect with customers — not just through messaging but through an integrated app. They can also be used to generate traffic and direct it to other platforms. For such purposes, people also build Mini Games to make the user experience more fun, engaging, and even a little addictive.
Mini Games and business tools are most popular cases within tApps. Gamification helps improve brand awareness and keep high retention rates. Businesses on Telegram create linkers, shops, and other apps to make the user experience more convenient.
Our design team has an experience in tApp development for these cases and knowledge of how to implement the best technical solutions for smooth app performance.
Despite its growing popularity, tApp development takes effort — not everyone is ready to invest in building their own app.
Mini App development challenges
Few agencies offer Telegram Mini App development for a reason. With its novelty and certain limitations of Telegram itself, it's still better to find a skilled development team — despite how rare they are — than to tackle everything on your own. Here’s why:

Hiring experts saves time and stress, giving you a product that does exactly what you need. Amen Agency is one of such teams. With experience in tApp development and knowledge of what it takes to make a good product, we help others get their desired mini app.
Amen experience with Mini App development
We found it interesting to explore mini app building as soon as this niche appeared. By combining the right tech support with our UX/UI design approach, we create a Mini App tailored to your needs — delivering its purpose and the results you want.
Let’s go through Amen’s Mini App case studies — they’ll give you a better idea of apps’ value, key features, and how they’re built.
Our TApps and Games
There are two complete games and one tap-to-earn app. Let’s take a look.
High Flyer
The game’s name expresses it’s main gameplay. The gameplay consists of a guy flying high above, and gathering weed to fill up his lifesaving bar. Single tap, and the game starts.
A video demo of the gameplay is better than a thousand words of explanation, and we welcome you to watch it.
When you bump into obstacles, the weed bar decreases, which makes it harder to score points and brings you closer to the end. Besides regular mode, there are various boosters and debuffs like shields, magnets, or two types of cannabis gummy bears — one gives a boost, and the other applies a debuff. The second gummy bear summons smog, preventing clear vision. The photo below is a collage of game screenshots showcasing possible effects — but not all of them are included, of course.
The goal is to fly as high as possible to beat up competitors on a leaderboard. This type of game can be a powerful tool for traffic generation. To attract users to the project, we create a game where players compete for real prizes, rewarding top spots on the leaderboard.
Such games can be easily improved. Adding skins, more levels, and rewards can make the game feel complete — a fun way to keep the community engaged as an extension of the main product.
Snoop Dogg
This game is inspired by the 'Crash' casino game with Snoop Dogg collaboration. The concept is pretty simple: Mr. Snoopy smokes a joint, and the multiplier rises until he stops randomly. The user makes a deposit and starts a game. If you guess the right moment and cash out before the game quits on its own, you win — otherwise, you lose.
While working on the game, we decided to go with a retro-futuristic style — kind of like the classic sci-fi movies we all know and love. The simplicity of the mechanics is decorated with a variety of backgrounds that you can contemplate while playing.
You can even check the gaming process with Snoop Dogg's live reaction.

This game was designed mainly for PC, but it can easily be adapted into a Mini App as there exists its mobile version.
Emojinn
Finally, it's the turn of the tap-to-earn experience so popular within Telegram Mini Games. We tried ourselves at this task and here’s the result.
Emojinn launches as any other Mini App through a bot.
Tapping earns you coins. Once the 'mana' in the bottom right runs out, you can still tap, but without gaining coins. Higher level — more coins.
You can also invite friends through a referral program.
Boosters help you earn coins faster. The 'Earn' button takes you to other ways to collect coins, usually by completing tasks inside or outside the app.
Business tools
Let’s dive into a topic of apps that aren’t extensions of other projects but can exist on their own. The Amen team has also contributed to this space by developing a freelancing platform within Mini Apps.
Polymathy
Polymathy is a telegram mini app created performing like a regular freelancing platform to post jobs and hire an expert for specific tasks.
There are two ways to use the app: as an executive, finding jobs that match your skills, or as a requester, looking for someone to complete a task. Uploading a post or applying to existing one costs 1 Telegram star.
The main page consists of job posts of any taste. A button to the right of the search bar can sort posts in a declining or increasing trend. Every post allows you to leave a comment (which costs 1 star) to apply to a request. It is possible to add tags relatable to the post topic.
The “Experts” page shows experienced individuals who have applied to requests numerous times and have good reviews on a platform. You may become one when you meet the requirements. Such a post shows name, hour rate, location, brief, and field of specialty.
Scroll down and see buttons to create job post and become an expert. If you have any ideas how the product can be upgraded, write down to developers with suggestions through the last button.
The "Profile" page basically shows your activities, suggest to become an expert, invites to referral program, or in case you can delete your account. There are also "Spin a Win Ticket" and "Contracts" features currently in prosuction.
The idea is simple: a Mini App built into a platform commonly used for business communication. This makes it easy to hire people for urgent tasks without relying on giant platforms with high fees or clunky chats. Here, there is no possibility of chat issues, as Polymathy launches in a messenger directly. Since Telegram works with TON, there’s potential to add smart contract agreements in the future to prevent scams.
How we choose architecture for Mini Apps
Back-end Development Basis
We choose Node.js for back-end development for several reasons. Node.js provides high performance due to its asynchronous, event-driven model. This allows us to efficiently process a large number of simultaneous requests without blocking the main thread. Let’s dive deeper into its implementation features.
NestJS
This progressive framework is used for developing server applications. It supports modular architecture, a strict code structure, and built-in Dependency Injection (DI), making it scalable and maintainable.
Asynchronous Processing
As mentioned earlier, NestJS natively supports async/await for handling asynchronous operations efficiently. WebSockets enable real-time communication, making it ideal for chat applications, notifications, and live updates.
Caching
We use Redis caching to reduce database load and speed up responses. This is particularly useful for storing frequently accessed data, session management, and rate-limiting mechanisms.
Structure-Performance Balance
NestJS allows us to write clean, scalable code without sacrificing performance. Its modular structure ensures maintainability while supporting high-load systems.
Architecture for High Loads
To ensure scalability and performance, we choose a microservice or modular approach, reducing the load on individual components of the system.
- Load balancing is handled using Nginx or PM2 in cluster mode, which helps distribute requests evenly across multiple instances.
- Database optimization includes proper indexing, query optimization, and caching of frequently used data to enhance performance.
- Background tasks are processed using BullMQ (a Redis-backed job queue), moving resource-intensive operations out of the main thread to ensure smooth API performance.
Technical Solutions
Here are some key technical decisions we apply in NestJS development:
- Real-time WebSocket connection on pure NestJS without third-party libraries.
- Ensures lightweight, efficient real-time communication without additional dependencies.
- Worker Threads for parallel processing of resource-intensive tasks.
- Moves CPU-intensive computations to background threads, preventing main thread blocking.
- Streaming data (such as video or logs) without overloading memory.
- Uses stream-based data handling, preventing excessive RAM consumption while serving large files.
- Monitoring and logging via Winston + Pino for non-blocking logs.
- Ensures high-performance, structured logging without overloading the main thread.
