Your browser wasn't built for juggling projects. Stack fixes that. Save any window as a named session not bookmarks, but real working context. Switch between sessions instantly with fuzzy search. Reopen a project days later and see exactly what changed: tabs added, tabs closed, what's still there. Think git diff, but for your browser. Inactive sessions auto-suspend to free memory and save battery. Keyboard-first, zero clutter, built for how you actually work.

Hey everyone 👋 I built Stack because I kept losing my place. I'd be deep in a project, 8 tabs of docs, APIs, a couple Stack Overflow threads then I'd need to switch contexts. Close everything, reopen something else, lose the thread completely. Stack lets you save a window as a named session and come back to it later. The feature I'm most proud of is Stack Diff - when you reopen a session, it shows you exactly what changed since you last had it open. Tabs you added, tabs you closed, what's still there. It's like git diff but for your browser. The free tier covers everything most people need. Pro adds encrypted cloud sync if you work across multiple machines. Would love to hear how you manage context-switching curious if this resonates or if I'm the only one drowning in tabs 😅
