Sentry
Depot pick for agent-error-observability (exceptions/traces in the app hosting the agent). Keep Langfuse/Helicone for LLM request tracing; Datadog when enterprise APM is already standardized. Strengths: Default error/trace monitoring every agent backend needs; MCP access on free plan for agentized debugging; Mature SDK
Strengths
- Default error/trace monitoring every agent backend needs
- MCP access on free plan for agentized debugging
- Mature SDKs across languages/runtimes
Weaknesses
- Not a substitute for LLM-specific eval/tracing (Langfuse/Braintrust)
- Span/replay overages can surprise
- AI Seer features are extra
PostHog
Flags/analytics peer. Depot oss-feature-flags pick stays GrowthBook; LaunchDarkly for AgentControl; PostHog when product analytics+flags should share one bill. Strengths: OSS + product analytics + flags + experiments in one bill; EU hosting option; Good agent-product telemetry without Datadog tax.
Strengths
- OSS + product analytics + flags + experiments in one bill
- EU hosting option
- Good agent-product telemetry without Datadog tax
Weaknesses
- Not a specialist LLM tracer (Langfuse/Helicone deeper)
- Many metered products — easy to enable bill surprises
- Flags depth vs LaunchDarkly enterprise controls
