Manual & terminal install

Prefer the command line? A single script detects your OS and installs the latest build:

The buttons above are all most people ever need. But if you’re comfortable with the command line, this one line works out which computer you have and installs everything for you:

curl -fsSL https://openhydra.co/install.sh | sh

Read it first if you like, it's just install.sh.

Per-platform, by hand

macOS, download the .dmg, open it, drag OpenHydra to Applications.

curl -L -o OpenHydra.dmg \
  https://dl.openhydra.co/latest/OpenHydra-macos-arm64.dmg
open OpenHydra.dmg   # then drag to /Applications

Linux, the AppImage is a single self-contained binary:

curl -L -o OpenHydra.AppImage \
  https://dl.openhydra.co/latest/OpenHydra-linux-x64.AppImage
chmod +x OpenHydra.AppImage
./OpenHydra.AppImage

Windows, download the .exe and run it. If SmartScreen warns, choose More info → Run anyway.

Already run an engine? Point any OpenAI-compatible tool at http://127.0.0.1:16527/v1 once OpenHydra is running, see the docs for connectors and engine setup.
