A primitive bug tracker for a freelancer?

Question

Freelance

Most of my projects - I'm the only developer, + 1 client, + a very small number of users (up to a couple of dozen).
Now all the bugs and improvements happen like this - the client writes to the chat in the cart, and ... the information is safely lost in a ton of discussions.
Are there really simple bug trackers / task trackers that are convenient for freelancing? Confusing bulky systems like Jira or Bugzilla, focused on teams. Tried Trello, for such tasks it is not very convenient

Answer 1

Github and bitbucket have it.

Answer 2

gitlab, trello

Answer 3

Webmail with filters by clients and within them, also by status folders: "in processing", "done".

Answer 4

basecamp,twist

Answer 5

Classic redmine is great

Answer 6

Customize Trello for tasks, as it is quite flexible.
Sometimes you need not a bug, but a task tracker (Todoist etc.).
It's fun to use the forum engine (as a user, I like Flarum).
