I am a MySQL developer and recently started to work on MSSQL for a project. I use MySQL workbench in local and PhpMyAdmin in servers. I wanted to have similar tools that I could use in local and in the server for MSSQL.
I googled and found a nifty tool Adminer. The beauty of this tool is it supports a lot of databases like PostgreSQL, Oracle and also NoSQL databases like MongoDB, Elasticsearch etc. The interface is not that intuitive though but it is fine to run most of the commands. I do not recommend it to use it for serious development but I liked it as I can do most of the works without switching to different tools for different database servers.
Similarly SQL Server Management Studio is too heavy and I needed a light weight tool. I found sqlectron and it made my life easy :-).
