A replica admin can now demote the instance back to a standalone
control without raw SQLite access. The Settings → Security UI surfaces
a confirm-gated button when the role is replica; the role probe also
surfaces a soft banner when it cannot determine fleet role rather
than silently defaulting to control.
Backend:
- POST /api/fleet/role/demote (admin, requires `{confirm: true}`):
flips fleet_role to 'control', clears fleet_self_identity,
fleet_control_identity, and both received_pushed_at:* watermarks,
drops every replicated_from_control row from scan_policies and
cve_suppressions, nulls out any orphaned policy_evaluation cache.
Returns 409 ALREADY_CONTROL when invoked on a control.
- DatabaseService gains `clearOrphanPolicyEvaluations()` and
`clearReplicatedRows()` helpers. Reanchor consolidates onto
clearReplicatedRows so it shares the same code path.
- `FleetSyncService.demote()` returns boolean for the route to
translate into 200 or 409.
Frontend:
- SecuritySection probes /fleet/role and now records explicit success
vs failure rather than silently treating an error as control. A
soft banner appears when probe fails.
- Replica banner gains a "Demote to control" button and a destructive
ConfirmModal explaining the wipe.
Tests:
- 4 new route-level vitest cases (401, 400 without confirm,
end-to-end demote with replica setup, 409 ALREADY_CONTROL with
explicit precondition).
- Service unit test asserts the consolidated clearReplicatedRows path.
- Full backend suite: 1773 pass / 5 skipped. Frontend: 185 pass.
Self-hosted Docker Compose management with self-healing infrastructure, atomic deployments, and multi-network fleet control. Built for engineers who want Kubernetes-grade reliability without the complexity.
Why Sencho?
Works across every network
Pilot Agent tunnels through NAT and firewalls so every node in your fleet is reachable from the dashboard, regardless of network topology. No port-forwarding. No VPN. No SSH.
Containers crash. Sencho fixes them.
Auto-heal policies watch your stacks and take action (restart, redeploy, notify) before you even open your laptop. Define the rules once; the recovery runs itself.
Deploy safely without Kubernetes
Atomic deployments mean a failed stack never leaves you in a broken half-up state. Rollback is one click. Deploy enforcement policies block non-compliant images before they ever run.
Define behavior, not procedures
Auto-update policies, scheduled operations, webhooks, and deploy enforcement let you codify how your infrastructure behaves. The UI is for oversight; the engine runs the work.
Features
Stack Management
- Monaco editor with syntax highlighting and multi-file support
- Atomic deployments with live progress tracking and one-click rollback
- Git-sourced stacks: pull and sync from any repository
- Stack file explorer and label management
Monitoring & Observability
- Live log streaming with search and filtering across all containers
- CPU, RAM, and disk threshold alerts with configurable actions
- Container stats, health checks, and image update notifications
- Global observability view across all nodes in your fleet
Fleet Management
- Multi-node via authenticated HTTP/WebSocket proxy (no SSH, no remote socket)
- Fleet view and sync for coordinated updates across nodes
- Pilot Agent for NAT traversal and firewall-crossing connections
- Node compatibility checks before deploying
Automation
- Auto-heal policies: detect and recover from container failures automatically
- Auto-update policies: roll out new image versions on your terms
- Scheduled operations with cron expressions
- Webhooks and deploy enforcement rules
Security
- SSO: custom OIDC (any spec-compliant provider), Google/GitHub/Okta presets, LDAP/Active Directory
- Two-factor authentication and RBAC with deployer, node-admin, and auditor roles
- Audit log, vulnerability scanning with VEX suppression, and private registry support
- Deploy enforcement to block non-compliant images
Operations
- App Store with one-click LinuxServer.io template deployments
- Sencho Cloud Backup for off-site stack archives
- Notification routing to Slack, Discord, email, and webhooks
- Global search across stacks and containers
Architecture
Sencho's architecture combines a Distributed API model with an optional Pilot Agent for complex networks.
- Distributed API: Remote nodes are managed by proxying authenticated HTTP/WebSocket requests to autonomous Sencho instances running on each server. No SSH. No remote Docker socket exposure. No polling agent. Each node speaks the same Sencho API, so the dashboard is just another client.
- Pilot Agent: For nodes behind NAT or strict firewalls, the Pilot Agent establishes secure outbound tunnels to the primary dashboard instance. This guarantees full fleet visibility and management without requiring port-forwarding, VPNs, or inbound network access.
Quick Start
Docker run (quickest):
docker run -d --name sencho \
-p 1852:1852 \
-v /var/run/docker.sock:/var/run/docker.sock \
-v sencho_data:/app/data \
-e COMPOSE_DIR=/opt/docker \
saelix/sencho:latest
Docker Compose (recommended for production):
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
Then open http://your-server:1852 and create your admin account.

Documentation
Development
# Backend (Express + TypeScript)
cd backend && npm install && npm run dev
# Frontend (React + Vite)
cd frontend && npm install && npm run dev
The frontend dev server proxies /api requests to the backend on port 1852.
