Sentry vs Datadog: Which MCP should you use?
Sentry
Error + performance monitoring for devs
Datadog
Full-stack observability platform
TL;DR
Sentry is a developer-first error + performance tracker — excellent for 'why did this deploy break?'. Datadog is a full-stack observability platform — infra metrics, APM, logs, RUM, security, and ~30 more products. Most teams use Sentry for app errors and Datadog (or competitors) for infra.
Pick Sentry
Pick Sentry when you want deep error context, release tracking, and developer-first UX.
Pick Datadog
Pick Datadog when you need a single pane for infra, logs, APM, security, and SLOs.

Migration path
They're complementary — most teams run both. If you must consolidate on Datadog: install dd-trace, enable Error Tracking, import Sentry projects via CSV (losing grouping history). Consolidating on Sentry: you lose infra/log/APM — usually not recommended unless you're small enough to not need them.
Frequently asked questions
What is the main difference between Sentry and Datadog?
Sentry is a developer-first error + performance tracker — excellent for 'why did this deploy break?'. Datadog is a full-stack observability platform — infra metrics, APM, logs, RUM, security, and ~30 more products. Most teams use Sentry for app errors and Datadog (or competitors) for infra. In short: Sentry — Error + performance monitoring for devs. Datadog — Full-stack observability platform.
When should I pick Sentry over Datadog?
Pick Sentry when you want deep error context, release tracking, and developer-first UX.
When should I pick Datadog over Sentry?
Pick Datadog when you need a single pane for infra, logs, APM, security, and SLOs.
Can I migrate from one to the other?
They're complementary — most teams run both. If you must consolidate on Datadog: install dd-trace, enable Error Tracking, import Sentry projects via CSV (losing grouping history). Consolidating on Sentry: you lose infra/log/APM — usually not recommended unless you're small enough to not need them.
Do Sentry and Datadog both work with MCP-compatible AI agents?
Yes. Both have MCP servers installable via MCPizy (mcpizy install sentry and mcpizy install datadog). They work identically across Claude Code, Claude Desktop, Cursor, Windsurf, and any other MCP-compatible client. You can install both side by side and route queries in your agent's prompt.

Grafana vs Datadog
Grafana is the open-source dashboard king, paired with Prometheus/Loki/Tempo (the LGTM stack). Datadog is the polished managed alternative — faster to deploy, easier to use, much more expensive. Grafana LGTM wins on cost and flexibility; Datadog wins on time-to-value and enterprise support.
Grafana vs Prometheus
Not competitors — they're paired. Prometheus is the time-series database and scraper. Grafana is the dashboarding UI. You run both: Prometheus collects and stores metrics, Grafana visualizes them. Grafana also supports Loki (logs), Tempo (traces), Elasticsearch, and 100+ other data sources.
Sentry vs Rollbar
Both are error-tracking services. Sentry has broader features (performance monitoring, session replay, profiling, release tracking, feedback widgets) and bigger developer mindshare. Rollbar is simpler, competitively priced, and good enough for most teams that only want errors.
Install both with MCPizy
