Go Web Frameworks interview question · Most asked
Compare Gin, Echo, Chi and Fiber.
Summary
Chi is a net/http-compatible router; Gin is the most popular framework with its own Context and tag-based binding; Echo is similar but handlers return errors handled centrally; Fiber is Express-like and built on fasthttp, so it isn't net/http compatible.
Longer Answer
Choose by needs and team: standard-library style and no lock-in (Chi), ecosystem and familiarity (Gin), centralised error handling (Echo), Express ergonomics or extreme throughput with simple handlers (Fiber). Router speed rarely matters compared with database time. Keep business logic framework-free either way.
Key Points
- Chi: router, standard handlers.
- Gin: popular, binding/validation.
- Echo: handlers return errors.
- Fiber: fasthttp, not net/http.

Explanation
What interviewers look for
Accurate trade-offs (especially Fiber's net/http incompatibility and context reuse) rather than benchmark talk.
