I know on the surface it sounds a lot like Jira, but the execution is subtly better across the board. A lot of it is design/UX related too.
And lastly, it's very snappy. At previous job I had to wait seconds for between clicks for Jira to update. I don't know how that's considered okay by Atlassian (but I'm not sure if they upsell you "faster Jira" lol)
Another thing that stood out to me was their "Linear Method" posts https://linear.app/method
The nice thing about it is that you can add whatever you like, however you like. Want components with default owners for tasks? Want milestones? Want stakeholders? Want sign-off reviewers? Want to integrate with existing tools like Linear or Notion or JIRA or even email inboxes or Slack messages? Add entities for Incidents, that automatically make a dedicated Slack channel when you create them?
Want proper 1:1 or 1:manu or many:many links between Tasks and Milestones and Sprints and Incidents and Teams and Components and whatever?
Want single assignees? Or multiple ones?
Want flexible custom reports on all of it?
Or just want a simple flat Todo list, that can evolve later to fit your needs?
Stop having the tools dictate to you how you work and instead set it up how your company actually wants to work. That's Fibery.
(I am not connected to the company, just a very happy user.)
It has an incredible amount of flexibility and customizability. PMs take that flexibility and turn it into a draconian list of requirements for tickets and workflows.
PMs want a million ways to extract and analyze information from tickets so they can create a hundred dashboards. The software engineers want simplicity so they can just quickly find what needs to be done, do it, and mark it as done.
Jira can be simple and easy. It's the PMs that turn it into a nightmare, but the hate gets targeted at Jira.
I have yet to see any organizational improvements in our delivery cadence or value derived from any of the planning elements of Jira. With all the doo-dads and buttons and fields and multiple ways of organizing things Jira is just a PM dopamine fidget spinner.
Post-Its on a whiteboard with dry-erase drawn columns is really all that's needed. Use a wiki for tracking longer lived todo lists and documentation.
