PaidGate and AdmiralGate were ~95% identical: same state machine (unlocked / compact-blurred / dismissed-pill / full-upsell-card), same 24h localStorage-backed dismissal logic, differing only in license predicate, dismiss-storage key, icon, and copy strings. Two reviewers flagged the duplication after PRs #874 and #875 landed identical changes in both files; the rule-of-three threshold is met. Extract the shared parts compositionally rather than as one big config- driven gate (the latter would just inline both gates' contents behind 8 props of indirection): - frontend/src/hooks/useDismissalState.ts owns the localStorage dismissal pattern. Lives under hooks/ to dodge the react-refresh/only-export-components lint rule that would fire if a hook coexisted with components in the same file. Validates the stored timestamp via Number.isFinite so a hand-edited or stale-extension garbage value defaults to "show the upsell" instead of crashing. - frontend/src/components/tierUpsell.tsx exports CompactBlurredLock, DismissedPill, and FullUpsellCard plus a shared TierGateProps interface. The compact-mode JSDoc lives on TierGateProps so the doc string lives in exactly one place. PaidGate and AdmiralGate become ~50-line compositions reading like a state machine. Public API of both gates is byte-stable: all 13+ consumers across the app continue to use <PaidGate featureName="X"> and <AdmiralGate featureName="X" compact> exactly as before. Two pre-existing security/polish issues fixed in passing while there is one source of truth for the affected JSX: - FullUpsellCard's window.open now passes 'noopener,noreferrer' to prevent the destination tab from accessing window.opener (reverse tabnabbing). - The Number.parseInt + Number.isFinite guard replaces a bare parseInt that would have happily accepted any prefix-numeric input. Adds a Vitest spec for useDismissalState covering: empty / recent / expired / non-numeric storage values, dismiss() / restore() side effects, the 24h boundary on fresh mount, and key independence.
Sencho
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.

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.
