@v0idd0/tabsnap.

browser session export → markdown / plain / json / readme cli.

cli twin of the tabsnap browser extension. pipe any tabs-shaped JSON (a flat array, a {tabs:[]} wrapper, or the extension's {windows:[{tabs:[]}]} shape), get back the format you want. use it when a tab graveyard needs to become a handoff note, a docs artifact, or a OneTab / Session Buddy alternative. optional --strip-tracking cleans common marketing params before you paste or pipe. zero deps, 5 KB tarball, mit.

browser twin

prefer the browser button instead of the terminal? tabsnap's extension exports the same markdown, plain text, json, and readme shapes from the toolbar, with zero telemetry and no account.

what it does

one engine, four shapes of output.

feed it any tabs-shaped JSON or browser-session dump. get back the format you want. optional tracking cleanup keeps pasted links tidy. no api call, no internet round-trip — just a tiny tool that does what it says.

why we built it

we built the tabsnap browser extension for snapshots from inside the browser. people then asked for the same thing in CI scripts and terminal pipelines. same engine, exposed as a cli — markdown, plain, json, readme.

no telemetry. no signup. zero runtime deps. mit forever. the browser extension and the cli share snapshot.js, so output bytes match exactly.
