Best Lightweight Ruby Web Framework for Your Needs

I recommend two lightweight web frameworks that are more suitable for writing web service interfaces: Grape and Sinatra. The main differences between the two are:

Grape is a pure API writing framework. It provides a lot of convenient functions for writing API. It is cool to write API with Grape and should be the first choice. It only provides output in json/xml/txt format.

Sinatra is a relatively complete Web framework with template rendering function, but if you simply write API, it is not as cool as Grape. However, if your API Server is likely to output HTML page fragments and template functions are needed, Sinatra is more suitable, otherwise it is still very troublesome to use Grape to spell strings in the code.

$300 coupon package for all new SMEs and a $500 coupon for paying customers.

Grape and Sinatra are both very lightweight packages based on Rack. I did a test of the frame processing request speed and a simple test of multi-threaded concurrency. Basically, the performance difference is very small. Grape is a little faster, but not more than 5%. Test Results

It is more suitable for writing a website framework. Of course, the most complete function is Rails, but I used Padrino to make my own website project and found it to be very good. I recommend you to use it.

Finally, when it comes to concurrency performance, my own test results show that Ruby's multithreading performance is very good when the amount of concurrency is not super high. Compared with Fiber, the performance difference is very small. I have done Goliath(raw code), Goliath(Grape), Rainbows(Grape), Puma(Grape), Rainbows(Sinatra), Puma(Sinatra), concurrent performance tests, which are basically on the same level. Test Results

So if you use Ruby to write a high-concurrency API server, even if you don’t use Goliath, you can use Grape/Sinatra to write the API and use Rainbows to run. The performance is also very good, and the manageability of Rainbows is also very good, as convenient as Unicorn .
