Sentry AI Monitoring - Pros & Cons
Pros
- ✓Combines AI observability with Sentry's existing error monitoring, tracing, logs, dashboards, and alerting, which is efficient for teams already using Sentry.
- ✓Tracks agent runs, LLM calls, error rates, token usage, tool executions, traffic patterns, and duration metrics from one monitoring environment when instrumentation is configured.
- ✓Provides cost and token visibility by model where supported by the relevant SDK and telemetry configuration.
- ✓Supports trace-level debugging with AI spans, agent invocations, tool executions, token counts, costs, timing, and configurable prompt and response context.
- ✓Has documented setup paths for Python OpenAI Agents and JavaScript Vercel AI SDK instrumentation, plus Sentry SDK coverage for common application stacks.
- ✓Business and Enterprise plans add operational controls such as quota management, SAML/SCIM support, longer lookback, and dedicated support options where included in the selected plan.
Cons
- ✗Most compelling for existing Sentry customers; teams not already using Sentry may need to adopt a broader observability platform just to get AI monitoring.
- ✗Total cost can rise with usage-based telemetry such as errors, spans, logs, replays, and attachments, so headline plan prices may not reflect real production spend.
- ✗Seer, Sentry's AI debugging agent, is priced separately at $40 per active contributor per month on Team and Business, which can add materially to team cost.
- ✗Dedicated LLM observability platforms may be a better fit for teams that want an AI-first product focused only on prompts, evaluations, datasets, and model experimentation.
- ✗Enterprise pricing is custom, so larger organizations will need a sales process to understand exact costs and contractual terms.
Helicone - Pros & Cons
Pros
- ✓5-minute proxy integration captures full traces, cost, and latency across 20+ providers
- ✓Real AI gateway features (caching, retries, fallback, key vault) replace a custom proxy
- ✓MIT-licensed and self-hostable on Postgres + ClickHouse — passes regulated procurement
Cons
- ✗Proxy mode adds a network hop unless self-hosted in your own region
- ✗Prompt experiment UX is less mature than dedicated eval platforms like Braintrust
- ✗Self-hosting requires running ClickHouse, which is an extra ops surface
