Best project management tool for webdev, for small/medium sized teams (5-10 people) and projects? Must include quick project setup with checklist templates.

Hmm we use Jira but we have huge extensive projects with multiple teams.. It's also not free. There are alternatives though that are pretty good. Google Jira alternatives, there are some free/cheap ones that are pretty good.

trello

We use JIRA too as a startup.

Trello or Asana are both good and do free versions to start with.

We use teamwork.com, it's not bad, lacks some features, but generally does the job.

We're 10 people, with 280 projects (small projects)

trello

Trellis is cool for big tracking. Not project management.
I always thought ManyMoon was cool.
