Install.
— curl one line, or build it yourself.
curl -fsSL https://hippobrain.org/install.sh | sh1 — Quick install (Apple Silicon)
The one-liner above downloads the latest release tarball, verifies its SHA-256 checksum, installs binaries to ~/.local/bin/, drops a default config at~/.config/hippo/config.toml, and starts the LaunchAgents. It runs withoutsudo and writes nothing outside your home directory.
About this script
The script is open source — read it before you run it.
2 — Manual installation
For contributors who want to build from source. Release binaries arearm64-only today; Intel Macs need to build from source.
# prerequisites: rustup, uv, mise, oMLX (or LM Studio)
git clone https://github.com/stevencarpenter/hippo.git
cd hippo
# build the daemon + brain
mise run installThe mise run install task does a full clean install: builds the Rust workspace, syncs the Python brain via uv, installs LaunchAgents under~/Library/LaunchAgents/, drops the Native Messaging manifest for Firefox, starts services, and runs hippo doctor to verify.
3 — Verify it’s working
Run the doctor. Ten checks, sub-second wall-clock, exit code = number of failures.
hippo doctorExpected output looks like the sample on the homepage. If you see[!!] or [WW], run hippo doctor --explain forcause / fix / doc per failure. The full failure-mode catalogue lives at/docs/capture/operator-runbook.
4 — Uninstall
Hippo doesn’t hide its uninstaller.
hippo daemon uninstall # removes LaunchAgents and binaries
rm ~/.local/share/hippo/hippo.db # if you also want to drop the databaseThe database stays untouched unless you remove it explicitly. The shell hook entry in ~/.zshrc is left as-is; the line is harmless if hippo isn’t running, but you can delete it if you prefer.
