I'm a designer and developer, and a hopeless tab hoarder. You know when your browser

has 70-something tabs open — every favicon crushed into an unreadable sliver — and

instead of finding the right one you just open another? That's me, permanently.

Bookmarks never helped; they're a graveyard I never reopen.

I bounced between a few tab managers (Toby and others), but kept bumping into

free-plan tab caps, so I built my own.

Mos Tab is a tab & bookmark manager that takes over your browser's new tab page.

Your open tabs show in a side panel — one click saves the good ones into spaces and

collections, and you close the rest. Drag to organize, instant search across

everything you've saved. And since you're staring at this page all day, there's

also a calendar, a pomodoro timer, to-dos, and sticky notes you can scatter around

— feels less like a blank void and more like a desk. All free, unlimited, no

account, works offline — your data just stays in your browser.

The part I'm actually excited about: you can connect Claude or ChatGPT over MCP. It

can search and summarize everything you've saved (tabs, notes, to-dos), and — the

fun part — save new stuff it finds into a brand-new space, add notes, or share it,

all from the chat. It only ever *adds* — it can't touch or reorganize your existing

spaces, which honestly made me trust it way more.

Example: I told Claude "find the top-rated budget strollers on Amazon, save them to

my tabs, and make a share link." It built a new "Stroller shortlist" space and

handed me a public link I sent straight to my wife — she opened it in her browser,

nothing to install.

Full disclosure: the stuff that runs on a server — sync, those public share links,

and the AI/MCP integration — is the paid tier. Local storage costs me nothing so

there's no reason to cap it, but the server stuff actually costs money to run, so I

can't give it away free — kind of wish I could. Just being straight about it.

Tab managers are a dime a dozen — I just wanted one where the basics stay free and

local, no cap. Would love feedback, especially on the MCP side.

Made a tab manager to fix my own tab-hoarding — then gave it an MCP server for Claude/GPT

A browser tab manager + new-tab dashboard — and Claude/GPT can save research into it
