If you’re the kind of person who keeps 20–100 tabs open, Chrome can get slow—and it’s hard to tell which tab is the culprit. TabCost makes it obvious and actionable. What TabCost does Shows per-tab memory (JS heap) when available Shows an Activity % estimate (how “busy” a tab is) Lets you hibernate (discard) tabs you’re not using Includes Search + filters: All / Heavy / Idle 10m+ Keyboard shortcuts: ↑/↓ navigate, Enter hibernate, Esc clear, Ctrl/Cmd + K search

Hey Product Hunt! I’m the maker of TabCost. I built TabCost because I constantly had too many tabs open and couldn’t tell which one was making Chrome slow. Chrome’s Task Manager is powerful, but it’s not “tab-workflow-friendly”—I wanted something that’s quick, searchable, and action-oriented. TabCost shows per-tab memory (JS heap) + a lightweight activity estimate, then lets you hibernate tabs you’re not using. It’s designed to be fast: open the popup, search, filter, hit Enter. I’d love feedback on: What thresholds feel “right” for Heavy tabs? What features would you want next (auto-snooze rules, groups, per-site insights)? Thanks for checking it out—happy to answer anything!
