What are Telegram Mini Apps?
Telegram mini apps are fast, install-free tools that run inside Telegram. Businesses create mini apps for onboarding, support, and in-chat transactions, no downloads needed.
Telegram mini apps work across devices and support complex logic like payments, forms, user accounts, and deep links, all inside the Telegram chat. Give users one-tap access to your service inside Telegram. Create a mini app that feels native, useful, and always within reach.

Where Telegram Mini Apps Work Best
We help teams launch Telegram mini apps that cover real tasks – payments, support, updates – right in the chat.


Benefits of Launching Telegram Mini Apps
Make onboarding instant, reach massive audiences, and run your app inside Telegram, so no 3rd party app store is needed.
Reach 1B+ audience

With Telegram now at 1 billion users (many of them are early adopters and crypto users) Overcode helps you build mini apps that live where people already are. No installs, no redirects, just tap, use, and stay in the chat.
Onboard users with ease

Mini apps launch instantly and skip the usual drop-off points: app stores, login forms, waiting screens. That means better user experience and higher conversion rates from the first interaction.
Go cross-platform

Telegram works on Android, iOS, macOS, Windows, and Linux. Your app runs everywhere without separate builds. Use one codebase, one update cycle, and no platform-specific maintenance overhead.

FREQUENTLY ASKED QUESTIONS
Answers to the most common questions about our software development process for mini apps on Telegram, cooperation models, and what it’s like to work with Overcode.
What types of services or functions are best suited for a Telegram mini app?
Mini apps in Telegram simplify the user journey and onboarding of users. This increases conversion rates. The cost of developing Telegram mini apps is much lower than the cost of a mobile app. These advantages are enjoyed by many services from categories such as:
- web3 companies;
- games and entertainment Apps;
- productivity and management tools;
- utilities apps;
- e-commerce, which includes online shops, product catalogues, and online storefronts;
- financial services, which include balance management, money transfers, bill payments, currency converter, and others;
- loyalty programmes, which include bonuses, discounts, and cashback;
- booking of services, e.g., rooms, tables, beauty treatments;
- customer communication, i.e., feedback, reviews, tech support, FAQs;
- education, i.e., educational content, tests, trainings;
- infoservices such as news, content aggregators, calculators, forecasts.
Describe your type of business, and we will tell you whether a Telegram mini-application will be suitable for your niche.
How can a mini app enhance my brand’s engagement with customers or users?
At the core of increasing engagement is customer/user interest and developing a connection with the brand. The customer likes to access products and services easily, quickly and conveniently. Engage well and build loyalty:
- gamification, which includes interactive quests, Challenges, rewards, savings programmes, competitions;
- personalisation, through which the customer receives special offers and solutions tailored to their interests, as well as adaptation of the interface to user habits;
- speed, i.e., prompt responses from chatbots, useful information via push notifications;
- integration with payment systems provides comfortable purchases;
- feedback, when direct contact with the brand is realised through feedback, voice and video calls.
By analysing user behaviour, the company can adapt the strategy and offer more relevant solutions. With the help of Telegram mini apps, the brand begins to understand customers better, interacts with them more actively, more conveniently, and more effectively.
What features can be implemented in a Telegram mini app (e.g., chatbots, forms, authentication, payments integration)?
Every customer has different needs and business models. Therefore, we adapt the list of functions to specific tasks. These can be features such as:
- chatbots, questionnaires and forms for data collection, subscriptions and notifications for informing;
- API integration, admin panel and CRM to automate processes;
- online catalogue, shop, payment system integration, loyalty programmes to increase sales;
- Telegram authorisation and data encryption for speed and security;
- analytics, geolocation, embedded multimedia, content navigation - consider the different functionality of mini-applications that help businesses to be more efficient.
Can you enable push notifications or event-based alerts through the app?
Of course, push notifications and automatic event-based alerts can be enabled in a mini app. This has a positive impact on communication, automates it, and saves time. Customers love a dynamic and convenient service:
- when relevant notifications come at the right moment, engagement and conversion increases (you'll need integration with CRM and analytics);
- when a customer is notified of an important event, order status, successful booking, discounts and personalized offers, it increases loyalty and retention.
For each project in development, we assign a separate project manager who reports to the client and manages the delivery team from Overcode.
Can the app connect with third-party APIs or external systems (e.g., CRM, ERP, or payment gateways)?
Yes, the Telegram mini app can be integrated with various APIs and external systems, which greatly expands its functionality. Here are the main types of integrations and their benefits:
- CRMs help manage customer data, automate marketing and improve personalised service.
- ERPs manage business resources and processes, which helps keep track of inventory, logistics, and reporting.
- Payment gateways manage online payments and make them easier and more secure.
- Analytics platforms collect and process data, make reports on user behaviour, which allows you to optimise your strategy.
Can you create a user-friendly and visually appealing interface for the mini app?
Yes. The usability and aesthetics of the interface are influenced by factors such as:
- Intuitive navigation means that a logical structure will make it easier to access key elements;
- Laconic design means clean lines, clear icons, and lack of clutter, which together will make the customer's journey more pleasant;
- Animations in the form of unobtrusive visual effects will add interest;
- Adaptability of the interface to different devices will improve the user experience;
- corporate identity (branded fonts and colours), which are responsible for recognition;
- Fast loading is possible when the code is optimised;
- User experience consideration is when the design matches the habits of the audience.
We aim to maximise engagement and comfort when using the mini-application.
Will the mini app be optimized for both mobile and desktop Telegram clients?
Yes, the Telegram mini app can be optimised for both mobile and desktop versions. This provides users with convenient access regardless of the device. The pros of such optimisation are:
- interface adaptation - it is convenient for the user to open and manage the app when it automatically adjusts to the screen size of mobile phones and computers;
- unified experience - differences between platforms are almost erased, which means no effort is needed for interaction;
- accessibility - the user can easily move from mobile to desktop and continue working without losing functionality.
Optimisation for both platforms expands the audience, increases user satisfaction and boosts engagement.
How do you ensure secure communication between the mini app and backend systems?
Several methods are used to secure communication between the mini-application and backend systems:
- data encryption using HTTPS to protect the transmitted information;
- authentication and authorisation through systems such as OAuth or Telegram authorisation to control access;
- API keys and tokens to protect interactions with external services;
- monitoring and auditing of security systems to prevent possible threats.
The listed measures are a guarantee of reliable data protection. They ensure secure interactions with external systems. Customers trust Overcode with their valuable information, and we ensure they are well-protected. We value your trust!
Can the app handle high user activity, such as during promotional campaigns?
Yes, the Telegram mini-app can be prepared for high user activity, especially during advertising campaigns. The following methods are used for this purpose:
- Server scalability is the use of cloud solutions to increase capacity under load;
- Code optimisation ensures improved application performance for fast response times with a large number of requests;
- Data caching gives faster access and reduced server load;
- Distributed databases are used for efficient data storage and processing;
- Load balancing distributes traffic evenly between servers.
These measures ensure the stable operation of the application at peak loads, ensuring user satisfaction.
Can the app be adapted to include new features or technologies over time?
Telegram is an actively developing product that is constantly adding new features to its application. We follow their releases and are ready to improve your application taking into account the latest innovations. Also, we can start from the scope of work of the project: first agree on the scope of work for the MVP, and then gradually expand the functionality of the mini-application.
New features will be easy to implement in any case, as we develop our projects on modern technologies that will be supported for a long time. We try to make our code as universal as possible within the project so that the application can be scaled.
Our client can re-apply to Overcode to plug in new features. We see great value in long-term partnerships with our customers. Therefore, we are ready to support and add new features to the client's product in the future.
Initially, we conduct testing for the main scenarios of using the product during its development. We can also additionally involve a QA specialist who will test the most unobvious variants of working with the application.
