Why we said Use
What it is
A platform for tracing, evaluation and agent-development workflows. See the official documentation or product page. This profile describes public documentation, not a Loaded Tokens hands-on test.
Who it is for
Teams debugging and evaluating model-backed applications. Our recommendation is scoped to that job; it is not a universal winner.
The evidence behind Use
Visible traces and evaluation workflows address a real need once an application has multiple steps. The vendor page documents the underlying capability; the fit judgment is ours. No performance ranking, time saving or reliability result is implied.
Pricing and the catch
Developer $0/seat/month plus usage, up to 5,000 base traces/month. Plus $39/seat/month plus usage. Public pricing checked November 7, 2026. Prices are USD where stated and can change; taxes, region, annual commitments and extra usage may differ.
Observability data can expose user inputs; review retention and access before sending traces.
A sensible first workflow
Trace a sanitized example and label the exact step where the output fails. This is a suggested evaluation, not a test we ran. Decide what success looks like before opening the tool: what output is acceptable, what needs review and where the workflow must stop.
Bottom line: buy for the job, keep the exit route, and do not confuse a feature list with proof of results. Browse the company profile for the rest of the stack.
