GTmetrix from the command line
Website speed tests, performance reports and fixes.
gbrain.io
Website speed tests, performance reports and fixes. GBrain gives GTmetrix, and every other application you connect, a command line.
One price for one person: GTmetrix and every other application GBrain connects, from a terminal or any AI. Cancel any time.
GTmetrix is connected on its own sign-in page, in the browser. A key or a sign-in never passes through the terminal.
# AI agents: read gbrain.io/llms.txt curl -sSL https://gbrainio.terminalwire.sh | bash gbrainio terminal connect
The installer is a shell script for macOS and Linux. Read it before you run it.
# Every GTmetrix command, once GTmetrix is connected gbrainio tool help gtmetrix
GTmetrix tests, monitors and helps optimize the speed of websites. Connected to a workspace, GBrain can answer “why did the pricing page get slower after Tuesday’s release?” by running a test, reading the report and comparing it with earlier results.
Signing in happens on GTmetrix’s own page. Running tests uses GTmetrix API credits; reading existing reports does not.
Each terminal reaches GTmetrix at the level set for it in the browser: Off, or On, which is every command GTmetrix's server lists. A terminal reads its level and never raises it.
Each of GTmetrix's commands stops at 1,000 actions a day on the account it reaches, whichever terminal or AI asks, and starts again at midnight UTC. Only that command stops.
Each command a terminal runs on GTmetrix is a row on GBrain's activity log: which terminal, which account, what it did and whether it was allowed, refusals included. gbrainio activity ls --tool gtmetrix reads it back.
GTmetrix's own server lists its commands only to a terminal that has connected it, so they are not on this page. Once GTmetrix is connected, gbrainio tool help gtmetrix says what each of them does, and gbrainio tool ls lists them with everything else the terminal can run. Claude Code and Codex run the same commands, at the same level, on the same record.
GBrain reaches GTmetrix at its own server, gtmetrix.com. On GTmetrix's own pages: its website, how the connection works, its terms of service and its privacy policy.
The GBrain Tools command line works with every other application GBrain connects, each with a page like this one.
Personal is $49 a month for one person. Connect GTmetrix in the browser, and say how far each terminal and each AI may go with it. Change any of it, or take all of it back, whenever you want.
