Cons
Con Can be buggy
HeidiSQL is known to have some bugs that results in crashes.
Con Intellisense is not intelligent
No intellisense for columns unless table name is aliased.
Con UI design is very bad
Generic windows form
Con No session backup
You cannot recover your session after close or even worse crash.
Con Works under Linux only with Wine
It works quite well under Wine with Linux, but you must always take notice if the last version of HeidiSQL has been tested, for it may not run at all. There are some bugs in the Wine version that can be annoying and you have to kill the program and restart it. A native Linux version would be great.
Con No built-in debugger included
Con Crashes constantly
Crashes when working with mysql 8.0.12 for macos 10.13. Unable to do anything.
Con Not maintained
The app crashes when you close a tab.
Con No MySQL 8 support
Con Not adapted for MacOS Catalina
Con No multiple query tabs
Sequel Pro does not support multiple query tabs in its editor. This is incredibly frustrating for a power user.
Con Text in the query lost on connection failure & crashes
Con OS X only, no Linux or Windows versions
Power users have to manage in many different environments. A consistent admin interface is hugely beneficial.
Con Query editing capabilities much poorer than MySql Workbench, Querious, and others
Con No visual query editor
Con Unable to import from binary SQL files
I frequently import binary multipolygon data from another source, and it won’t open.
