The Control Plane for OpenTelemetry.
Deploy, govern, and cost-optimize your entire collector fleet — neutral to any backend, audited end to end, and ready for the AI agents that will run it tomorrow. Free to use, self-hosted on your infrastructure.
✓ Fleet is stable. All agents running policy v1.4.1.
SSH into 50 servers to change one config
Manual config edits across hundreds of nodes are slow, error-prone, and impossible to audit.
Restarting collectors = telemetry gaps
Every collector restart tears down network sockets and drops data. Users notice.
No idea if your fleet is healthy
Collectors fail silently. By the time you notice missing data, the incident is already live.
Built for Engineers Who Need Fleet Control
Managing OpenTelemetry Collectors across hundreds of servers, Kubernetes clusters, and Windows machines is painful. CollectorCtrl replaces SSH scripts and manual config edits with a centralized, policy-driven control plane — every change authenticated, authorized, and written to an audit trail.
Three-Component Architecture
Simple, secure, and designed for production on your own infrastructure.

What CollectorCtrl Does
Real features, shipping today, based on the OpAMP open standard.
Who Uses CollectorCtrl
Platform & SRE Teams
Manage OTel Collectors across dev, staging, and production from one dashboard. Roll out config changes to specific environment rings. Detect unhealthy agents before they impact telemetry pipelines.
Security & Compliance
Stream every action to your SIEM via OTLP. Audit who changed what config and when. Enforce RBAC with SSO group mapping.
Multi-Cloud Observability
Run the server on-prem or in your VPC. Agents connect outbound — no inbound firewall rules needed. Works across AWS, Azure, GCP, and private data centers.
Pipeline & Cost Governance
The control plane is where the observability bill is decided. Build custom OTel Collector binaries with the integrated OCB Builder, filter and sample before data reaches expensive backends, and deploy the right version to the right machine with fleet policies.
Up and Running in Minutes
No cloud account required. Runs entirely on your infrastructure.
Install the Server
Download the Windows installer or Linux tarball. The server runs as a native service. SQLite works out of the box.
Install Agents
Deploy the Supervisor on each node. The installer registers it as a Windows Service or Linux systemd unit automatically.
Manage from the UI
Open the dashboard at port 4321. Log in, view your fleet, create policies, and push configs — no SSH needed.
