Tied to LangChain for observability?
There's a better way. Vendor-neutral agent observability at $10 per million spans. OpenTelemetry native. Unified with your infrastructure traces.
Oodle can help you if
- ✓You use multiple LLM frameworks (not just LangChain)
- ✓You need LLM traces correlated with backend infrastructure
- ✓You want one platform for traces, logs, metrics, and APM
- ✓You prefer open standards over proprietary SDKs
- ✓You run at production scale where per-trace pricing hurts
Oodle is probably not for you if
- —You're fully committed to the LangChain ecosystem
- —You only need LLM observability with no infra monitoring
- —You rely heavily on LangSmith's prompt hub for team collaboration
Why teams choose Oodle over LangSmith
LangSmith is built for LangChain. Oodle is vendor-neutral and unifies LLM traces with your infrastructure.
LangChain-First Design
LangSmith added OTel support, but their own docs still recommend the native format for performance. Auto-instrumentation is seamless for LangChain - other frameworks need manual setup. Oodle is OpenTelemetry-native by default with no preferred framework.
No Infrastructure Platform
LangSmith can receive OTel spans, but it doesn't provide APM, logs, or metrics. When an agent is slow, you still need a separate tool to check the database or API gateway. Oodle shows the full request lifecycle in one platform.
Cost at Scale
LangSmith's per-trace pricing grows with volume. Oodle's $0.30/GB storage-based model means costs stay predictable at millions of traces per day.
Oodle vs LangSmith - Feature Comparison
| Feature | Oodle AI | LangSmith |
|---|---|---|
| Pricing model | $0.30/GB (~$10 per million spans) | Per trace (tiered pricing) |
| Framework lock-in | Vendor-neutral - OpenTelemetry native by default | OTel supported but native format recommended for performance |
| Infrastructure trace correlation | Built-in - LLM spans live in same traces as API, DB, cache | OTel context propagation available; no native APM/logs/metrics |
| Instrumentation standard | OpenTelemetry GenAI semantic conventions | LangSmith SDK, @traceable decorator, or OTel (added 2025) |
| Prompt versioning & evals | Yes - built-in LLMOps workflow | Yes - core feature with prompt hub |
| Logs, metrics, APM | Full unified platform | Not available - LLM observability only |
| AI-powered debugging | Natural language queries across all signals | LLM-based trace clustering (Insights); no NL query across signals |
| Production scale | 3M+ agent traces/day, S3-native serverless | Cloud-hosted, scaling varies by plan |
| Compliance | SOC 2 Type II, ISO 27001, GDPR | SOC 2 Type II |
$10 per Million Spans
LangSmith charges per trace. Oodle charges $0.30/GB - that works out to ~$10 per million spans at any scale.
