We don't have good number of quality web series in bengali but I recommended you worth watching web series. 


1. Taqdeer:  

Personally I recommended you the web series. The story of the web series hook you in-front of screen. The screenplay, color, background music were fantastic. This is a well made bengali crime thriller till now.  Through the story we see that a freezer van driver found  a unknow body in his van and then we will see what incident happened  with him. The performance of the start were marvellous. 

IMDB:8.9

2. Rahasya Romancha: 

This is also crime, thriller. The dialogue of the characters were memorable you don't forget. Screenplay, backgroundmusic hook you in the whole series. When you start watching the series you finish at one time. I love the unique story line. You should  definitely try this webseries.

3. Byomkesh


Leaving out Byomkesh will be an absolute failure of mine. The famous detective character Byomkesh is known personally, and this Hoichoi series giving a piece of the renowned personality was a pleasure to watch.

The plot which needs no introduction in simple words is a mysterious thriller where as usual, a detective is assigned to solve the mystery. A masterpiece with some excellent directions makes Byomkesh a must watch Bengali web series on our list.
