Log search

The viewer supports full-text search over log bodies and filters for time, project, service, and severity; text matching is case-insensitive and whole-word only. source

Purpose

Bilis stores and searches application logs and traces, with a web viewer for filtering, live tail, and trace inspection. source

Retention

Hosted log records are retained for 30 days and then deleted automatically; the free plan also states 30-day retention for logs and spans. source

Security

The maker states that hosted data is encrypted in transit with TLS and at rest, API keys are stored as hashes, production access uses multi-factor authentication, and project data is isolated at the query layer. source

Storage format

Logs and spans are stored in OpenTelemetry-compatible ClickHouse tables that the maker describes as portable and readable by other tools. source

Structured log parsing

Yes source

Support

Hosted service support is by email on business days; the Team plan offers priority support through a direct line. source

Trace viewer

Traces are shown as span waterfalls, with logs and traces linked to each other by trace ID. source
