Pulse

Infrastructure monitoring that finds what needs attention.

Live demo · Documentation · Releases · Discussions

Pulse is a self-hosted monitoring workspace for Proxmox, Docker, Kubernetes, TrueNAS, physical and virtual machines, and early-access VMware vSphere environments. It combines live infrastructure state, history, alerts, recovery visibility, and scheduled health checks without requiring a conventional enterprise monitoring stack.

Why Pulse

• It watches between visits. Alerts and Pulse Patrol find failed backups, capacity pressure, restart loops, unhealthy containers, clock drift, and other problems that dashboards cannot surface when nobody is looking.
• It keeps each platform familiar. Proxmox, Docker, Kubernetes, TrueNAS, vSphere, and machines have dedicated views, backed by one shared resource model for search, alerts, history, and investigation.
• It stays operator-controlled. Credentials are encrypted at rest, API tokens are scoped, agent commands are disabled by default, and governed fixes require the configured policy and approval path.

Platform coverage

Platform	Coverage
Proxmox VE, PBS, and PMG	Nodes, guests, storage, backups, replication, Ceph, mail gateways, and alerts
Docker and Podman	Hosts, containers, Compose projects, Swarm services, health, images, and updates
Kubernetes	Clusters, nodes, workloads, pods, services, storage, and events through the unified agent
TrueNAS SCALE and CORE	Pools, datasets, disks, snapshots, replication tasks, apps, VMs, and alerts
Linux, Windows, and macOS machines	Host health, filesystems, networking, temperatures, RAID, and availability through the unified agent
VMware vSphere	Early-access inventory, hosts, clusters, VMs, datastores, networks, snapshots, and recovery context; validate against your own vCenter before production use

Platform pages keep storage and recovery information beside the infrastructure it belongs to. Alerts, Actions, and Patrol remain cross-platform views.

Patrol: monitoring that does rounds

Pulse Patrol runs scheduled checks across the current state and recent history of your infrastructure. Community installations can use a local model or their own AI provider for watch-only analysis. Pulse Pro adds investigation and policy-bound fixes with approval, verification, and an audit trail.

Pulse also includes an interactive Assistant and an MCP adapter for external clients such as Claude Code and OpenCode. Both sit on top of the same scoped inventory, metrics, alert, storage, and governed-action contracts.

Quick start

Choose an exact version from the latest release and keep that version pinned during installation.

Docker

docker run -d \
  --name pulse \
  -p 7655:7655 \
  -v pulse_data:/data \
  -e PULSE_DEPLOYMENT_METHOD=docker_run \
  --restart unless-stopped \
  rcourtman/pulse:vX.Y.Z

Open http://<your-ip>:7655 and follow the bootstrap-token setup. Docker host monitoring is provided by the unified agent; the Pulse server container does not need the Docker socket.

Proxmox LXC, Linux, and Kubernetes

• Signed Proxmox LXC and Linux installation
• Docker Compose
• Kubernetes and Helm

The installer is signed. Verify install.sh against the pinned pulse-installer key before running it:

export PULSE_VERSION=vX.Y.Z
curl -fsSLO "https://github.com/rcourtman/Pulse/releases/download/${PULSE_VERSION}/install.sh"
curl -fsSLO "https://github.com/rcourtman/Pulse/releases/download/${PULSE_VERSION}/install.sh.sshsig"
ssh-keygen -Y verify \
  -f <(printf '%s\n' 'pulse-installer namespaces="pulse-install" ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIMZd/DaH+BldzOkq1A8KVTcFk73nAyrE8aJOyf7i00jm pulse-installer') \
  -I pulse-installer \
  -n pulse-install \
  -s install.sh.sshsig < install.sh
bash install.sh --version "${PULSE_VERSION}"
rm -f install.sh install.sh.sshsig

The GitHub installer installs the Pulse server. Install and upgrade agents (including v5-to-v6 agent upgrades) with the per-host command generated under Settings → Infrastructure → Install on a host.

Do you need an agent?

Often not. Proxmox VE, PBS, and PMG are monitored through the Proxmox API with a read-only token, so nothing runs on the host and the generated setup script creates a privilege-separated monitoring user. Install the unified agent only where you want data the platform API cannot provide, such as host SMART health, temperatures, Docker hosts, or standalone machines.

The agent is operator-controlled by design. Command execution is off by default, the local listener binds to localhost, and generated systemd units ship hardened. On Linux, the installer's --least-privilege profile runs the service as a dedicated non-root user, with optional scoped sudo grants for the few collectors that need elevation. The agent security model documents exactly what the agent can and cannot do at each privilege level.

Important

GitHub release assets and rcourtman/pulse images are Community builds. Relay, Pro, and eligible legacy customers should use the private image or Linux archive provided by the Pulse download portal. Replacing a private Pro runtime with a public Community build removes its private runtime hooks.

Editions

• Community — self-hosted monitoring, seven days of metric history, core SSO, update alerts, and Patrol with your own provider or local model.
• Relay — Community plus secure remote web access, Pulse Mobile pairing, push notifications, and fourteen days of history.
• Pro — Relay plus Patrol investigation, governed fixes, ninety days of history, centralized agent profiles, RBAC, audit logging, and reporting.
• MSP — for managed service providers: one Pulse Account running many client workspaces, each with an isolated Pulse runtime — separate dashboards, alerts, users, audit history, and reports. Free sixty-day two-client evaluation at Pulse for MSPs.

Core self-hosted monitoring is not gated by monitored-system or child-resource volume. See the runtime-aligned capability reference and current plans for details.

Development

Pulse uses Go 1.26 and a SolidJS/TypeScript frontend. The managed development runtime starts the frontend at http://127.0.0.1:5173 and proxies API and WebSocket traffic to the backend on port 7655.

npm ci
npm --prefix frontend-modern ci
npm run dev

Useful checks:

go test ./...
npm --prefix frontend-modern test
npm --prefix frontend-modern run type-check
python3 scripts/check_public_docs.py

See CONTRIBUTING.md before investing in a code change. Pulse uses an issue-first contribution process and does not normally accept unsolicited pull requests.

Community and support

• Ask questions in GitHub Discussions.
• Report reproducible bugs through GitHub Issues.
• Home Assistant users can use the community-maintained Pulse add-ons.
• If Pulse is useful to you, support its development through GitHub Sponsors or Ko-fi.
