* fix: harden deploy/update concurrency and node-targeting safety Release stabilization for deploy/update operational safety. Per-stack operation locking is now global. Background lifecycle paths (scheduler auto stop/down/start/backup/update, webhook execute, Git source auto-deploy, image auto-update, label bulk actions, fleet snapshot redeploy, and mesh redeploy) acquire the per-node, per-stack lock through a new StackOpLockService.runExclusive helper and skip rather than race a manual deploy/update/rollback/backup on the same stack and node. Skips surface honestly (a failed scheduled run, a recorded webhook failure, a per-stack batch result, or a thrown error) instead of a silent no-op. Update readiness and policy-bypass now run against the node captured when the dialog opened, not the live active node, so switching nodes while a dialog is open cannot retarget the update or the bypass retry. Rollback readiness no longer presents a moving-tag or unpinned image as a ready image revert. Restoring files does not revert a moving tag, so those stacks read as partial, and the rollback success message states that the compose and env files were restored. * fix: lock blueprint reconcile against manual ops and correct rollback wording Follow-up to the deploy/update safety hardening, closing two more gaps from a verification pass. BlueprintService.deployLocal and withdrawLocal called ComposeService directly, so blueprint reconciliation could race a manual deploy/update/rollback/backup on an owned stack. Both now run their compose lifecycle call through StackOpLockService.runExclusive and skip (recorded as a failed reconcile, retried on the next cycle) on conflict. The withdraw holds the lock across both the compose down and the directory delete so neither races a manual operation. The runtime rollback messages overstated recovery: a rollback restores the compose and env files and recreates containers, but does not revert an image behind a moving tag. The auto-rollback deploy-progress output, the recovery panel and chip, the failure toasts, and the manual rollback route message now state that the compose and env files were restored, with the matching OpenAPI example and atomic-deployments doc updated. * fix: acquire stack lock before blueprint deploy mutates compose and marker files Local blueprint deploy wrote the compose and marker files and ran the policy assert before acquiring the per-stack lock; the lock only wrapped the deploy itself. A reconcile could therefore rewrite an owned stack's files while a manual deploy/update/rollback/backup was running. The lock now wraps the whole critical section (create, write compose, write marker, policy assert, deploy), so on conflict nothing is written and the reconcile records a failed outcome. Adds a test asserting a deploy under a held lock records failed, writes no marker file, and leaves the manual lock untouched. * fix: make remote blueprint apply atomic under the receiving node's stack lock Remote blueprint deploy wrote the compose and marker files to the target node via separate HTTP calls and only locked on the final deploy, so the file writes could race a manual operation on that node. A node's operation lock is process-local and cannot be held by the hub across HTTP calls, so the locked create/write/deploy now runs on the receiving node. The locked critical section is extracted into BlueprintService.applyLocalUnderLock and exposed via POST /api/blueprints/apply-local. The hub posts the blueprint to that endpoint in one call; the receiving node runs create + write compose+marker + deploy under its own per-stack lock. Older nodes without the route answer 404 and fall back to the legacy multi-call flow. The endpoint is gated by paid tier and the same per-stack stack:edit and stack:deploy permissions as the PUT-compose + deploy it bundles, validates the stack name, compose size, and marker structure, and returns 409 on a lock conflict without writing anything. Adds tests for the atomic single-call path, the 404 legacy fallback, the 409 lock-conflict mapping, the route validation and permission paths, and the write-compose-then-marker-then-deploy ordering of the shared locked apply. * fix(deps): bump undici to 7.28.0 to clear high-severity advisory The frontend CI npm audit gate (--audit-level=high) failed on a transitive undici 7.25.0 (a dev-only dependency via jsdom): TLS certificate validation bypass (GHSA-vmh5-mc38-953g) and cross-user cache information disclosure (GHSA-pr7r-676h-xcf6). Bumping undici within jsdom's existing ^7.25.0 range to 7.28.0 clears the high-severity advisory and unblocks the frontend job. Lockfile only; no direct dependency or source change.

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.
