New framework for Go (Golang) gains popularity: what developers need to know

The Go (Golang) ecosystem continues to actively develop. In recent months, the developer community has been attracted by a new framework that promises to change the approach to building web applications and microservices. We are talking about the Fiber v3 project — a powerful evolution of the popular Express-like framework that has already won the trust of thousands of developers worldwide. According to GitHub data, over the last quarter the number of repository stars has grown by 40%, and the number of commits has doubled.

Why Fiber v3?

Fiber was originally positioned as a fast and minimalist framework inspired by Node.js Express. Version 3 has received a number of fundamental improvements:

• Full compatibility with net/http. Now the framework works seamlessly with the Go standard library, simplifying migration of existing projects.
• Built-in middleware support. Developers can easily connect ready-made modules for logging, CORS, compression, and authentication without additional dependencies.
• Improved performance. According to community tests, Fiber v3 processes up to 1.5 million requests per second on standard hardware, making it one of the fastest HTTP frameworks for Go.
• Support for WebSocket and Server-Sent Events (SSE). Built-in tools for real-time communications without needing to connect third-party libraries.

What are developers saying?

On Reddit forums and in Go community Telegram chats, it is noted that Fiber v3 has become a real lifesaver for those tired of bulky frameworks like Gin or Echo. "We rewrote two microservices on Fiber v3 over the weekend. The code became cleaner, tests run faster, and memory usage is lower," shares an engineer from a company specializing in fintech solutions.

The key advantage is simplicity. Fiber uses a familiar routing API that is easy to learn even for beginners. At the same time, the framework retains all the power of Go: goroutines, channels, and zero memory abstraction.

Comparison with competitors

The Go framework market has traditionally been dominated by Gin, Echo, and Chi. However, Fiber v3 wins due to:

• Initialization speed. An application on Fiber starts 20-30% faster than its counterparts.
• Documentation. The official website contains dozens of code examples, video tutorials, and ready-made project templates.
• Community. An active Discord server with 5000+ members where you can get help within an hour.

Prospects and forecasts

Analysts note that Fiber v3's popularity is growing not only among startups but also in large corporations. For example, Uber and Dropbox are already testing the framework for internal tools. If the trend continues, by the end of the year Fiber could enter the top three most used Go frameworks according to the JetBrains Developer Survey.

For developers who want to stay on trend, now is the best time to get acquainted with the new tool. Installation is simple: just run the command go get github.com/gofiber/fiber/v3 and start writing code.
