* feat: add Compose Doctor preflight checks for stacks Add an on-demand, advisory preflight that renders a stack's effective Compose model with `docker compose config` and runs a registry of deterministic checks before deploy, surfacing findings grouped by severity (blocker, high, warning, info) with a remediation for each. Findings cover unset env vars, host-port conflicts on the node, broad 0.0.0.0 exposure, missing bind-mount paths, a mounted Docker socket, privileged and host networking, moving image tags, missing restart policy and healthcheck, Swarm-only deploy fields, missing external networks or volumes, and container_name collisions. The report is node-scoped and stored as the last run per stack, and the route auto-proxies to the active node so a remote stack is checked on the node that owns it. A new Doctor tab on the stack detail panel runs preflight and shows the grouped findings, with a severity dot on the tab when the last run has blocker or high findings. The tab is gated on a compose-doctor capability so older nodes hide it. No environment value is ever stored, returned, or logged: only env key names and structural facts are read, and render failures surface a generic message or the missing required-variable names, never raw stderr. * fix: scroll the stack tab strip when its tabs overflow Adding the Doctor tab can push the per-stack Anatomy tab strip past the panel width on narrower layouts. Make the tab row scroll horizontally with subtle edge fades that appear only while there is more to scroll in that direction, so a panel wide enough to show every tab is unchanged. * fix: add clickable arrows and wheel scroll to the stack tab strip Hiding the scrollbar left mouse users with no way to scroll the overflowing tab row: a vertical wheel does not move a horizontal overflow and native rows do not drag-scroll. Replace the passive edge fades with clickable chevron arrows shown only when the row overflows that edge, and translate a vertical wheel over the row into horizontal scroll. * fix: inline the path-injection barrier in renderConfig CodeQL's path-injection check does not credit the wrapped isPathWithinBase helper as a sanitizer, so move the containment check inline at the spawn cwd sink, matching the canonical barrier used elsewhere in the codebase. Behavior is unchanged: the resolved stack directory must be contained in the compose base and may not be the base itself. * fix: hoist the compose-config spawn into the path-barrier scope The earlier inline barrier sat in a different scope than the spawn cwd sink (separated by the Promise-executor closure) and used a compound guard, so CodeQL did not credit it. Use the exact canonical startsWith barrier and hoist the spawn into the same scope as the check. Behavior is unchanged: the executor runs synchronously in the same tick as the spawn, so handlers still attach before any event can fire.
Self-hosted Docker Compose management for one machine or a fleet.

Note
Sencho is currently in public beta on the path to v1.0. Core workflows are actively tested, but early users should review the known limitations and avoid deploying it blindly on critical infrastructure without testing in their own environment first.
What Sencho is
Sencho is for homelab operators, small DevOps teams, and platform engineers who run services on Docker Compose, want a graphical interface without giving up file-on-disk workflows, and need to manage more than one machine without SSH gymnastics or a VPN.
It runs as a single container on your hardware and gives you a UI for the work you currently do over SSH on compose stacks: deploying, editing files, watching logs, restarting containers, browsing volumes, and recovering from failures. Your compose files stay on the host filesystem and remain the source of truth.
A Sencho instance is autonomous. To manage another machine, you install a second Sencho on it and connect them with a long-lived API token; the primary dashboard then acts as an authenticated HTTP and WebSocket proxy across your fleet. Use TLS, a VPN, or a private network for any untrusted link. Each node still uses its local Docker socket (see Quick start), but Sencho does not require SSH and does not expose a remote Docker socket on the network. For nodes behind NAT or strict firewalls, the Pilot Agent establishes a single outbound WebSocket tunnel to the primary, so the remote host opens no inbound port at all.
Most capabilities are free in the Community tier. A few advanced governance, security, and fleet-control features ship in the paid Admiral tier; pricing lives at sencho.io/pricing.
What Sencho is not (yet)
Sencho is a Docker Compose control plane focused on homelab and small-fleet operators. It is intentionally not:
- A Kubernetes scheduler or replacement.
- A reverse proxy. Front Sencho with your existing proxy (Caddy, Traefik, nginx) for TLS and authentication on the public edge.
- A monitoring stack. Sencho surfaces container and host metrics in the dashboard but does not replace Prometheus, Grafana, or your existing alerting pipeline.
- A CI / CD pipeline. Use webhooks, the API, or Git-sourced stacks to connect Sencho to your build system.
See KNOWN_LIMITATIONS.md for the current limitation list.
Tier coverage: All bullets below are available in the free Community tier unless marked (Admiral). Full breakdown at sencho.io/pricing.

Before you install
Sencho talks to Docker through the host's /var/run/docker.sock. Mounting this socket grants Sencho the same privilege as sudo docker on the host. This is the same model used by Portainer, Dockge, Komodo, and other Compose dashboards. If your threat model requires stricter isolation, see running with a non-root container user and front Sencho with a reverse proxy that enforces authentication.
Quick start
Sencho runs in a single container.
services:
sencho:
image: saelix/sencho:latest
container_name: sencho
restart: unless-stopped
ports:
- "1852:1852"
volumes:
- /var/run/docker.sock:/var/run/docker.sock
- ./data:/app/data
# 1:1 Compose Path Rule: the host path MUST match the container path
- /opt/docker:/opt/docker
environment:
- COMPOSE_DIR=/opt/docker
- DATA_DIR=/app/data
docker compose up -d
Open http://your-server:1852 and create your admin account.
Always front Sencho with a TLS-terminating reverse proxy in production. See the self-hosting guide for hardening, environment variables, and reverse-proxy examples.
Run with docker run instead
docker run -d --name sencho \
-p 1852:1852 \
-v /var/run/docker.sock:/var/run/docker.sock \
-v sencho_data:/app/data \
# 1:1 Compose Path Rule: the host path MUST match the container path
-v /opt/docker:/opt/docker \
-e COMPOSE_DIR=/opt/docker \
saelix/sencho:latest
For the full walkthrough, see the quickstart guide.
Adding remote nodes
To manage a second machine, install Sencho on it the same way, then add it from the primary dashboard with its URL and a long-lived API token. The primary proxies authenticated HTTP and WebSocket requests to the remote instance. The remote node does not run SSH for Sencho, does not expose its Docker socket on the network, and does not run a separate agent process. The local Sencho on each node manages its own Docker through the standard socket mount described in Quick start. Nodes behind NAT or strict firewalls can opt into the Pilot Agent for outbound-only connectivity.
See the multi-node guide for the full token-bearer flow.

Telemetry and data handling
Sencho does not emit telemetry, analytics, or crash reports. The only outbound traffic is license validation against Lemon Squeezy, and only when a paid license key is activated. Community-tier instances make no outbound calls to Sencho-controlled endpoints. Stack metadata, container inventory, and user activity never leave your instance.
