See which app is eating your data — live, per-app, over any time window, right in your terminal.
(demo GIF here — live dashboard catching a spike + a datasip app chrome --since 30m query)
Built for anyone on a metered connection — 5G home routers, tethering, travel eSIMs, ISP data caps. datasip watches your traffic, remembers it, and tells you which app spiked and when — even while you were away.
Those show you traffic right now. datasip also remembers, so you can ask questions about the past:

Ask any window (--since 30m/8h/30d) |

# Go (single binary, recommended)
go install github.com/zainulabidin302/datasip@latest
# Homebrew (coming soon)
brew install zainulabidin302/tap/datasip
# From source
git clone https://github.com/zainulabidin302/datasip && cd datasip && go build -o datasip .datasip # live dashboard: gauges, sparklines, top apps, spikes
datasip app chrome --since 30m # how much did Chrome use in the last 30 minutes?
datasip app chrome --since 8h
datasip apps --since 24h # ranked leaderboard for a window
datasip spikes --since 24h # when apps spiked, and how hard
datasip stats # daily totals + billing-cycle usage
datasip config --allowance 50 --cycle-day 1 # data-cap bar--since accepts 5m, 30m, 8h, 7d, 30d, 2w.
Keep logging (and catching spikes) even when the dashboard is closed, via a launchd agent:
datasip log # foreground; wrap in a launchd plist for background usePure macOS built-ins (netstat, nettop) sampled once a second, aggregated into
tiny per-minute buckets in ~/.netwatch/. No kernel extensions, no root, no
telemetry, no dependencies at runtime.
Regenerate the README GIF reproducibly with vhs:
brew install charmbracelet/tap/vhs
vhs demo.tape # writes demo.gif(Start a download or open a busy site in another window first, so the live dashboard shows real traffic — and maybe a spike — while recording.)
