summary: Safe, sandboxed runtimes for autonomous AI agents
description: |
  OpenShell provides safe, sandboxed runtimes for autonomous AI agents.
  It offers a CLI for managing gateways, sandboxes, and providers with
  policy-enforced egress routing, credential proxying, and privacy-aware
  profile-backed model-provider access.

  The OpenShell snap ships a CLI (`openshell`), a terminal UI
  (`openshell.term`), and a managed gateway daemon (`openshell.gateway`).

  **Setup instructions**

    1. Install and start Docker using your preferred package source before
       installing the OpenShell snap. Use a system package or Docker's package
       repository. The Docker snap is not currently compatible with OpenShell.

       Snap Store installations automatically connect the required interfaces.

       If the OpenShell snap was installed before Docker was running, it may
       have hit the systemd start limit when trying to repeatedly start and
       connect to docker. If this is the case, it can be resolved by doing:

         sudo systemctl reset-failed snap.openshell.gateway.service
         sudo snap restart openshell.gateway

    2. Give your user the gateway client certificate and register the gateway.
       The gateway requires mTLS; only users holding this certificate can use
       it, so copy it only for trusted users:

         snap services openshell.gateway
         d=~/snap/openshell/common/.local/state/openshell/tls
         mkdir -p -m 700 "$d" "$d/client"
         sudo install -o "$USER" -m 600 /var/snap/openshell/common/tls/ca.crt "$d/"
         sudo install -o "$USER" -m 600 -t "$d/client" \
           /var/snap/openshell/common/tls/client/tls.crt /var/snap/openshell/common/tls/client/tls.key
         openshell gateway add https://127.0.0.1:17670 --local --name openshell
         openshell status

# The system :docker slot was added in snapd 2.76, so this is the minimum
# required version. Snapd 2.77 allowed manual connection to that slot without
# snap-declaration overrides from the store, such as when installing a locally-
# built snap, but that is not required for installations from the snap store.
