Tool Breakdown
Grafana Cloud
Grafana Cloud's free tier is explicitly free forever with no credit card required, and it's built on the open-source Grafana stack — giving teams a path to self-host later without vendor lock-in, something Datadog's closed platform doesn't offer.
- Free tier is explicitly free forever — 10k active metric series, 50GB each of logs/traces/profiles, 14-day retention, 3 users, no credit card
- Built on the open-source Grafana project (74.8k GitHub stars, actively released as of this writing), giving a self-hosting escape hatch if needed
- Pro tier's $19/mo platform fee is a low entry point before usage-based overages apply
- Pro tier pricing is platform fee plus metered usage, not a flat price — costs can climb with scale (e.g. $6.50 per 1,000 series over the free cap)
- Less deep cross-product correlation between infra, APM, and logs than Datadog's tightly integrated platform
Datadog
Datadog is an infrastructure monitoring and APM platform with usage-based, per-host pricing and a narrow free tier limited to basic infrastructure monitoring.
- Unifies infrastructure monitoring, APM, log management, and security in one platform with deep cross-product correlation
- Large integration ecosystem covering most cloud and infrastructure tooling out of the box
- Fully managed — no self-hosting or open-source maintenance burden
- Free tier is narrow — capped at 5 hosts with only 1-day metric retention
- Closed-source platform with no self-hosting option, unlike Grafana's open-source foundation
Frequently Asked Questions
Is Grafana actually free, or is that just the open-source version? +
Both, but in different ways. The underlying Grafana software is open source and free to self-host. Grafana Cloud, the hosted product compared here, also has a free-forever tier (10k metric series, 50GB logs/traces/profiles) — but Pro usage above that is metered and paid.
Which is better for a team that doesn't want to manage open-source infrastructure? +
Datadog, since it's a fully managed, closed-platform service with no self-hosting option or maintenance burden. Grafana Cloud is also fully managed, but its open-source roots mean some teams choose to self-host instead.
Which platform has the more generous free tier? +
Grafana Cloud. Its free tier is explicitly free forever with no credit card required, while Datadog's free tier is capped at just 5 hosts with only 1-day retention.
