Bifrost AI Observability review
Gateway-level telemetry for teams tracking LLM costs, routing, and reliability.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Bifrost AI Observability captures telemetry for LLM and agent calls that pass through its gateway. It is aimed at teams that want to monitor request content, token use, cost, latency, status, and routing details, with costs attributed to provider, model, virtual key, team, or customer. Its free, open-source OSS edition is self-hosted, making it a fit for teams prepared to run the gateway and manage their own trace retention. Teams looking for evaluations should consider a different tool.
The monitoring detail extends beyond basic request logs. Teams can query logs through an API by provider, model, status, and time range, export OpenTelemetry traces using GenAI semantic conventions, and expose Prometheus metrics for successes, errors, tokens, costs, and cache hits. Routing and failover traces include retries and key rotations; MCP tool-call duration and failure rate are also measured. Content logging can be disabled while retaining request metadata, which gives teams a way to limit captured content without losing operational signals.
The OSS plan costs $0 and includes built-in observability, OpenTelemetry-compatible metrics and traces, budget management, and rate limits. Enterprise pricing is custom; that tier adds private deployment options, SSO, alerts, log exports, and audit logs. The published pricing page says Enterprise has a 14-day free trial. Prometheus, Grafana, Datadog, New Relic, Honeycomb, Langfuse, Arize Phoenix, and compatible collectors are among the listed integrations, with exports also available to storage and messaging systems such as BigQuery, S3, GCS, Kafka, and Pub/Sub. Choose Bifrost for gateway-centric telemetry and cost attribution; skip it if evaluations are central or you do not want to self-host.
