$0.99 · Designed for iPad. Not verified for macOS.

Open OTLP trace JSON offline, rebuild span trees, expose critical paths, error clusters, clock gaps, and attribute hygiene. Spanprism is an on-device OpenTelemetry trace explorer for developers and SREs who cannot or do not want to send diagnostic traces to a hosted backend. Turn local OTLP trace JSON evidence into a prioritized, editable review with explicit assumptions, ownership, and exportable decisions. KEY FEATURES - Native OTLP trace JSON import and normalization - Interactive critical path prism - Editable spans with owners and evidence - Deterministic latency findings scoring - Current-versus-proposed state comparison - Decision log with accountable disposition - Portable trace evidence packet export - Private offline workspace with no account - Native structured-file or CSV import - Local PDF, workspace JSON, and domain-artifact export - 48 original offline technical reference plates - No account, ads, analytics, tracking, IAP, or subscription Spanprism analyzes imported trace payloads and timestamps. It does not collect live telemetry, account for backend sampling transformations, or prove causality. Confirm clocks, instrumentation, sampling, and service behavior in the source systems.
