Grafana Agent Observability sends structured generations and OpenTelemetry signals through separate documented paths into the Grafana stack. Logfire keeps agent calls, application spans, database queries, logs, metrics, and infrastructure in one queryable workflow.
Logfire uses PostgreSQL-compatible SQL across telemetry, so developers and coding agents can ask ad hoc questions without switching among PromQL, LogQL, and TraceQL as they move between signals.
Logfire's Live View shows pending spans: requests in flight, model calls that have not completed, and tool operations still in progress. That makes it possible to investigate a slow agent before the user-facing request has finished.
Ask Logfire Assistant questions about project or organization telemetry in plain language, follow its answers into the supporting evidence, and use SLOs to track the error budget and burn rate behind each service.

Calculation scope
Two independent Grafana Cloud Pro pricing dimensions: published Agent Observability generation charges beginning October 1, 2026, and current 30-day trace telemetry using the public calculator's Process and Write bands. Evaluator tokens and extended retention remain separate.
Basis: USD; public monthly list price and calculator bands. Prices checked .
Grafana's published generation rate starts billing October 1, 2026. Trace telemetry and LLM-based evaluator or guard tokens are separate; this estimate stops before those workload-dependent meters.
$49 $49 (5M − 10M included) ÷ 1M × $2 $0 $19 $19 (5M − 30K included) ÷ 1K × $1.50 $7,455 Grafana's published generation rate starts billing October 1, 2026. Trace telemetry and LLM-based evaluator or guard tokens are separate; this estimate stops before those workload-dependent meters.

$49 $49 (500M − 10M included) ÷ 1M × $2 $980 $19 $19 (500M − 30K included) ÷ 1K × $1.50 $749,955 The first 50 GB is included in each current trace meter; the remaining volume is priced inside Grafana's published graduated Process and Write bands. The included 30 days does not add a Retain charge.

The official calculator shows 20 million records and no extra seats totaling $69/month on Team.
“Platform fee of $19 per month includes:”
Grafana Cloud Pro includes 50 GB of traces, then separately meters processing, writing, and retention with graduated volume bands.
“Volume-based, tiered pricing”
The calculator publishes the exact Process, Write, and Retain brackets used below, including the 50 GB allowance within each meter.
“Generation usage is billed separately from token usage for LLM-based evaluations and guards.”
Grafana says generation and evaluator/guard token billing starts October 1, 2026; ordinary trace telemetry billing is already active.
“If you decide to retain data in excess of 30 days, you'll be charged $0.10 per GB.”
Grafana's invoice documentation describes Retain as an additional charge for each retention period beyond the included 30 days.
Logfire uses one OpenTelemetry-native telemetry path for application and AI spans. Grafana Agent Observability sends structured generation data to its API and emits traces and metrics over OTLP into the Grafana stack. Self-hosted Grafana teams choose and operate their own backends.
Not with Logfire. It uses PostgreSQL-compatible SQL across traces, logs, and metrics, so developers and coding agents can investigate the full stack without switching among PromQL, LogQL, and TraceQL.
Yes. Logfire's Live View renders pending spans before a request completes, including model calls and tool operations that are still in progress. This lets you inspect a slow agent while its user-facing request is still running.
Logfire traces model calls, tool activity, costs, and agent runs alongside application and infrastructure telemetry. Ask the in-product Assistant about any of it in plain language, then follow its answers into the underlying evidence.
Yes. Both support OpenTelemetry, so you can send the same traces to Logfire and your existing Grafana setup during evaluation, compare the same debugging task in both, and transition gradually — starting with new projects or AI workloads.
