About Lightarch
Observability shouldn't cost more to leave than to use.
Most observability platforms charge you to send data in, charge you again to get it back out, and store everything in a format only they can read. Lightarch was built to remove all three — traces, logs, and metrics land directly in your own Cloudflare R2 bucket, as open Apache Iceberg tables, with nothing proprietary underneath.
Your data, your bucket
Every trace, log, and metric is written into your own Cloudflare R2 bucket as open Apache Iceberg tables — not a proprietary format locked inside our systems.
No egress tax
R2 has zero egress fees by design. Query your data, export it, move it — none of that costs extra, ever.
OTel-native
Built on OpenTelemetry from the start. No proprietary SDK to adopt and later regret.
Real isolation
Every tenant gets a dedicated D1 database and R2 bucket. Your data never shares infrastructure with anyone else’s.
Lightarch runs entirely on Cloudflare — Workers, D1, R2, and Pipelines — end to end. No separate infrastructure to manage, no other vendor in the middle.
