FastAPI Development Services
We develop fast, secure, and scalable backends using FastAPI. This high-performance Python framework automatically generates OpenAPI schema and interactive documentation, and enables low-latency request handling and high throughput. To businesses, it provides a technological edge that supports stable application performance even under heavy loads.
Many software products — streaming platforms, public-facing AI tools, and chat applications — must handle thousands of concurrent users. In such solutions, performance issues can result in reduced operational efficiency and higher customer churn rates. This makes FastAPI an invaluable tool for building custom software optimized for speed and scalability.
Despite being relatively new compared to its alternatives, FastAPI boasts the highest reported adoption rate among Python web frameworks at 38%, according to a 2024 JetBrains developer survey, which also indicates a growing popularity over the last several years.
Benefits of FastAPI Development
Exceptional Performance
Thanks to its support for asynchronous programming out of the box and WebSockets, FastAPI can process multiple I/O operations simultaneously and is able to generate low-latency responses. This makes it particularly well-suited for high-load, high-concurrency projects such as AI-powered applications and real-time back-end services.
Fast, Affordable Development
FastAPI is a developer-friendly framework, offering a variety of convenient features such as type hints and automatic data validation, which simplify the engineering process. On the business side, this can significantly reduce overall development costs and ensure a fast time to market for both MVPs and full-scale applications.
Automatic API Documentation
The framework automatically generates OpenAPI schema for your endpoints and serves interactive API documentation, enabling frontend teams to start integration once the schema is defined. For your project, this implies reduced manual documentation effort and faster collaboration between teams, which can accelerate release cycles and simplify long-term maintenance.
Well-Established Toolkit
FastAPI is fully compatible with other standard Python tools, libraries, and ecosystems, which all continue to grow. In addition, being a modern web framework, FastAPI has a wide, active developer community. This is another factor that simplifies and speeds up development, as it opens additional opportunities for solving challenges that may arise throughout project implementation.
Built-in Security Features
FastAPI comes with support for OAuth2 security helpers and input validation by default. This makes it easy to implement protection against injection attacks and similar threats at early development stages, and contributes to a robust set of security features that safeguard the final product against unauthorized access or data theft.
Our FastAPI Development Services
FastAPI is perfect for fast, high-throughput web and mobile applications that process thousands of requests simultaneously, such as public services, AI chatbots, and streaming platforms. Here at SysGears, we can develop these applications from the ground up, handling everything from concept refinement to deployment and post-release updates.
Custom API Development
Our development team can build powerful, scalable REST APIs custom-tailored to your software needs. FastAPI-powered solutions ensure high-speed, high-security connections with other applications and services, which greatly contribute to higher customer retention and improved operational efficiency.
Microservices Architecture
SysGears creates fault-tolerant, maintainable microservice architecture solutions powered by FastAPI, which ensures low latency, high throughput, and streamlined scalability. We can build a robust architecture from scratch if you’re developing a new solution, or split an existing monolithic application into independent modules to make it easier to expand and maintain select services.
Framework Version Update
We can update the FastAPI framework of your application to the latest version, ensuring security and optimal performance with minimal disruption to your business operations. This lets you access new functional features, improved scalability support, and up-to-date security measures as the technology evolves.
Migration to FastAPI
Have a web application built with Flask, Django, or another framework, but now want to make use of async/await patterns, type hints, and automatic OpenAPI docs? We can rewrite your solution’s code with FastAPI, keeping functionality unchanged or improving upon it as needed, and letting you leverage features designed for high concurrency and real-time processing.
Third-Party Integrations
We can implement integrations with payment gateways, cloud providers, AI services, CRMs, and other tools, both internal and third-party, using FastAPI for better latency and throughput. This has the potential to broaden your business’s reach with software partnerships and improve operational efficiency thanks to reduced need for manual data processing.
SysGears also provides expert FastAPI consulting services, including assistance with architecture choice, IT strategy development, budgeting, and more. We can analyze your existing solution to provide actionable insights for optimizing it, or lend a hand with developing an all-new application, API, or service.
