Sentry
Error + performance monitoring for devs
Rollbar
Real-time error tracking
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.
Pick Sentry when you want errors + performance + session replay + releases in one tool.
Pick Rollbar when you want pure error tracking at a lower price, with simpler UX.

Both SDKs follow a similar init + captureException pattern. Swap the npm/pip package, update DSN/token env var, rebuild source maps upload in CI. Historical errors don't migrate — keep old dashboard read-only for a quarter. A typical swap is 1-2 hours per service.

Yes. Both have MCP servers installable via MCPizy (mcpizy install sentry and mcpizy install rollbar). 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.
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.
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.
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.
Not sure? Run both side by side — swap between them in your AI agent with a single config line.
