The bottom line

Pricing: Grafana is completely free, which makes it the obvious pick if budget is the top concern. Datadog starts at $15/host/mo, but Free for up to 5 hosts with basic metrics. That cost buys you a more polished or feature-rich experience, so it comes down to whether the extras justify the spend.

Feature gaps: Datadog offers APM, Infrastructure Monitoring and Log Management that Grafana lacks. Grafana brings Data Sources and Open Source that Datadog does not have. Both share Alerting and Dashboards.

Team fit: Datadog is geared toward enterprise teams, while Grafana is aimed at any size teams. Pick the one that matches where your team is today and where it is headed — migrating tools later is always painful.

Open source: Grafana is open source, meaning you can self-host, audit the code, and avoid vendor lock-in. Datadog is proprietary — you are trusting the vendor with your data and uptime.

Where each tool shines: Datadog's biggest strengths are: most comprehensive monitoring platform available. 750+ integrations covering virtually every technology. Grafana's biggest strengths are: open source and transparent. customizable dashboards give real-time visibility into project progress.

Watch out for: With Datadog, users commonly note that pricing is complex and gets very expensive at scale. With Grafana, the main complaint is that may lack some advanced features.
