A CLI tool that auto-instruments any project with OpenTelemetry, validates spans locally, and shows traces in a browser without a cloud backend

Setting up OpenTelemetry in local dev and CI means wiring collectors, configuring exporters, guessing at span correctness, and spinning up a cloud backend before you see a single trace. No tool auto-instruments a project from the command line, validates that spans are semantically correct, and runs a local trace viewer in the same step. This CLI fills that gap: one command detects language and framework, injects OTel instrumentation, watches the span stream in real time, and opens a lightweight local UI for trace exploration, with a headless CI mode that fails the build when spans are malformed or missing.

I got OpenTelemetry to work. But why was it so complicated?

Gap Assessment

CompetitiveMultiple tools exist but differentiation opportunities remain

4 tools exist (Superlog (YC P26), Honeycomb, Dash0, Grafana Tempo) but gaps remain: Requires a cloud backend and internet connectivity; no offline local trace viewer, no headless CI span-validation mode, no instant zero-signup local feedback loop during development.; Fully cloud-hosted; local dev requires exporting spans to the cloud; per-event pricing starts at $130 per 100M events, making local iteration expensive; no CLI auto-instrumentation..

Competitive LandscapeFREE

Product	Does	Missing
Superlog (YC P26)	AI-agent wizard scans a repo and adds OTel instrumentation, then routes telemetry to a hosted Superlog Cloud backend for incident grouping and auto-fix PRs.	Requires a cloud backend and internet connectivity; no offline local trace viewer, no headless CI span-validation mode, no instant zero-signup local feedback loop during development.
Honeycomb	Cloud-based distributed tracing and observability platform with OTel ingestion, high-cardinality querying, and BubbleUp anomaly detection.	Fully cloud-hosted; local dev requires exporting spans to the cloud; per-event pricing starts at $130 per 100M events, making local iteration expensive; no CLI auto-instrumentation.
Dash0	OpenTelemetry-native observability platform with transparent per-datapoint pricing; full traces, metrics, and logs in one UI.	Cloud-hosted SaaS with no local-dev-first mode; no CLI auto-instrumentation; no span validation or local viewer without account creation.
Grafana Tempo	Open-source distributed tracing backend that accepts OTel spans; can be self-hosted.	Requires deploying Tempo plus Grafana to view traces; no auto-instrumentation; significant setup overhead; not a CLI tool and not designed for local dev inner loop.
