Apache 2.0 Open Source

Apache 2.0 Open Source

Your FREE, Self-Hosted
Observability Lake

🌊 Drowning in telemetry?
💰 Tired of surprise vendor bills?
😫 Done wrestling bloated self-hosted stacks?

Just write structured telemetry to an S3 bucket, and let LakeRunner do the rest – indexing, compaction, aggregation, and streaming queries – all handled at petabyte scale.

No Blackboxes,
No Vendor Lock-In

LakeRunner is Apache 2.0 Open Source – no strings attached.

Use the Grafana plugin for exploration and dashboarding – no vendor-specific UIs to migrate to and learn.

Prefer the terminal? Use the LakeRunner CLI to query logs, leveraging the full power of the *nix toolchain.

OpenTelemetry-Native,
Other Formats Welcome

Already running an OpenTelemetry Collector? Simply add the S3 Exporter to write to a bucket, and watch as LakeRunner makes your data instantly queryable.

But that's not all – LakeRunner can also index other structured file formats, such as Apache Parquet, JSON, or CSV, so you can bring along relevant data from other sources, too.

Autonomous Monitoring,
Powered by Chip

You shouldn't need to worry about the uptime and reliability of your Observability stack – all LakeRunner deployments get forever free, out-of-the-box monitoring with Chip, Cardinal's autonomous monitoring agent.

Chip can also monitor your own services that send telemetry to your Observability lake – so you can spend your time building and shipping, rather than tuning and managing alerts.

"We used Cardinal to help us build an on-prem Observability Data Lake, and are in the process of replacing our incumbent storage layer.

An open Data Lake hosted within our own VPC gives us the flexibility to build custom user experiences on top of the data for our stakeholders and customers."
