The issue tracker you'll actually love using.
Streamline software projects, sprints, and bug tracking with a tool designed for speed and high-performance teams.
Trusted by engineering teams everywhere
Precision at every scale
Everything your team needs to plan, build, and ship — without the bloat that slows you down.
Lightning-fast issue tracking
Create, triage, and resolve issues in milliseconds. Keyboard-first navigation keeps your team in flow without ever touching a mouse.
Sprints that run themselves
Automated cycles roll incomplete work forward, surface blockers, and keep velocity visible so planning takes minutes, not meetings.
Projects with real context
Group issues into projects with leads, targets, and progress. Every stakeholder sees exactly where things stand at a glance.
Built for the whole team
Invite teammates, assign roles, and collaborate with comments and attachments. Workspaces keep everything organized and secure.
Trusted by engineering teams
Thousands of teams switched and never looked back.

“The keyboard shortcuts alone changed how our team works. Everyone moved off the old tool within a week.”
Daniel Okafor
Staff Engineer
“Sprint planning used to be a two-hour ritual. Now it is a ten-minute scroll. Flux earns its place on every screen.”
Priya Nair
Product Lead
“Clean, fast, and quietly powerful. It gets out of the way and lets the engineers focus on the work.”
