* fix(webhooks): close HMAC timing oracle on trigger reject paths The trigger handler in PR #1177 returned a uniform 404 for every unauthenticated rejection, but only the wrong-signature path computed an HMAC over the request body. The other reject paths (unknown id, disabled webhook, non-paid tier, missing X-Webhook-Signature header, missing rawBody) short-circuited before any HMAC work. Repeated near-rate-limit probes with a large attacker-controlled body could distinguish a valid-and-enabled paid webhook id from the other reject cases through response latency. WebhookService.validateSignature is now constant-time over every input shape: it always runs crypto.createHmac and crypto.timingSafeEqual against fixed-length 32-byte buffers regardless of whether the signature is missing, has the wrong prefix, is malformed hex, or is the wrong length. The trigger handler calls it unconditionally before any reject branch fires, using a stable per-process decoy secret (WebhookService.getDecoySecret) when the webhook does not exist and an empty buffer when the request has no body. Response timing now depends only on the size of the request body, which the attacker already controls and which reveals nothing webhook-specific. Six new tests pin the behaviour: validateSignature is observed firing on the unknown-id and missing-signature paths through a spy assertion, and four direct-call tests confirm validateSignature returns false without throwing for empty, wrong-prefix, malformed-hex, and wrong-length signatures. * fix(safe-log): redact Basic auth and lowercase Windows drive letters The redactSensitiveText helper now covers two cases the prior chain missed: * Authorization: Basic <base64> previously left the base64 payload intact. The existing key/value regex caught only the literal word Basic before stopping at the space. A new Basic\s+[A-Za-z0-9+/=]+ replacement runs before the key/value regex so the credential is scrubbed first. * Windows homedir paths like c:\Users\<user>\... with a lowercase drive letter previously slipped through because the regex required [A-Z]. Changed to [A-Za-z] so both letter cases are covered. Two new tests pin both fixes. * docs(webhooks): document 429, fix shared schema, comply with D27/D31 * Trigger endpoint declares the 429 response that webhookTriggerLimiter can return (500 requests per minute per source IP); both docs/openapi.yaml and the response table in docs/features/webhooks.mdx carry the new row, and a new troubleshooting accordion explains the shared-NAT scenario. * Shared Webhook schema in docs/openapi.yaml extends the action enum to include git-pull and documents the node_id property. The GET list endpoint returns these fields; the prior schema would have failed validation for any git-pull row. * docs/features/webhooks.mdx:7 rewritten from a customer-side role enumeration ("non-admins on a paid tier can view the list but cannot manage it") to a single requirement statement ("Webhooks require a Skipper or Admiral license. Managing webhooks is admin-only.") per CLAUDE.md D27/D31; the prior phrasing was customer-side fence-spec. * Two em dashes in webhook description strings I had touched in the prior OpenAPI sync commit replaced with semicolons per D18.

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 a transparent HTTPS proxy across your fleet. There is no SSH and no exposed Docker socket. 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 automation and fleet-control features ship in paid tiers; pricing lives at sencho.io/pricing.

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 \
-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 HTTPS and WebSocket requests to the remote instance. No SSH, no exposed Docker socket, no agent process on the remote. 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.
