Grafana Cloud Free Tier: The Most Generous Forever-Free Observability Stack in 2026
You’re running a side project on a $5 VPS, and it goes down at 3 AM. Your logs are scattered across SSH sessions, your metrics are a mystery, and your only “alert” is a user tweeting that your API is dead.
You need observability—but you’re not ready to pay for it.
Here’s the good news: Grafana Cloud offers a permanent free tier that’s so generous it feels like a bug. 10,000 metric series, 50 GB of logs, 50 GB of traces, and 50 GB of profiling data—every month, forever, with no credit card required. Let’s break down exactly what you get, how to set it up, and where the limits bite.
What Is Grafana Cloud?
Grafana Cloud is the hosted version of the Grafana observability stack. Instead of self-hosting Prometheus, Loki, and Tempo, you get a fully managed “LGTM” stack (Loki for logs, Grafana for dashboards, Tempo for traces, Mimir for metrics) plus a bunch of extras like k6 load testing, synthetic monitoring, and on-call incident response.
The killer feature? The free tier isn’t a 30-day trial. It’s “always free” and “no charges ever” according to Grafana’s pricing page, which lists the full breakdown. You get a production-grade observability platform with zero upfront cost.
Free Tier Breakdown (Verified July 2026)
Here’s what you get on the free plan, per month:
| Feature | Free Tier Allocation |
|---|---|
| Metrics | 10,000 active series (14-day retention) |
| Logs | 50 GB ingested (14-day retention) |
| Traces | 50 GB ingested (14-day retention) |
| Continuous Profiling | 50 GB ingested (14-day retention) |
| k6 Load Testing | 500 virtual user hours |
| Synthetic Monitoring | 100k API tests + 10k browser tests |
| Kubernetes Monitoring | 2,232 host hours + 37,944 container hours |
| OnCall/IRM | 3 active users |
| Dashboards | Up to 1,000 per stack |
The 14-day retention is the main trade-off. You can’t do year-over-year trending on the free tier. But for active debugging and alerting, 14 days is plenty.
Setup Guide: From Zero to Observability in 20 Minutes
Step 1: Create Your Account
Head to the Grafana Cloud sign-up page and register with email, GitHub, or Google OAuth. No credit card. No “start trial” button that secretly enrolls you in billing.
Step 2: Get Your Stack
Your stack is auto-provisioned with managed Prometheus (Mimir), Loki, and Tempo endpoints, plus an API key. You’ll see the endpoints and keys in the Grafana Cloud portal under “Details.”
Step 3: Send Metrics
The easiest path is the in-UI quickstart, but for real projects, install Grafana Alloy, the official collector. It’s a single binary that can scrape Prometheus endpoints and forward to your cloud stack.
Step 4: Send Logs
Use Alloy’s loki.source.file component to tail log files and forward them to your Loki endpoint. This is the modern replacement for Promtail and handles multi-file ingestion cleanly.
Step 5: Send Traces
Add the OpenTelemetry SDK to your app and export OTLP to your Tempo endpoint. Grafana’s send-data documentation covers the exact configuration for popular languages.
Step 6: Frontend Observability
If you have a web app, install the Faro Web SDK to get Core Web Vitals, JavaScript errors, and session data in your Grafana dashboards. This turns your free tier into a full RUM (Real User Monitoring) platform.
Step 7: Import Dashboards
Skip the blank canvas. Browse Grafana’s dashboard library with 6,000+ community dashboards. One click imports Node.js, PostgreSQL, Nginx, or Kubernetes dashboards with pre-built panels.
Step 8: Set Up Alerts
Create alert rules in the UI and route them to email, Slack, Discord, or PagerDuty. You get 35 rule groups with 20 rules per group—plenty for personal projects.
Practical Tips to Maximize the Free Tier
-
Watch your cardinality. The 10,000 active series limit is the easiest to blow. Avoid high-cardinality labels like
user_idorrequest_idin Prometheus metrics. Use logs or traces for high-cardinality data instead. -
Use Agent-level filtering. Alloy can drop labels and filter logs before they ingest, saving your 50 GB log budget.
-
Set usage alerts. Grafana Cloud can alert you when you approach your usage limits. The usage limits documentation shows how to configure these.
-
Leverage k6 for load testing. The 500 virtual user hours per month is a free load testing tool that integrates directly with your dashboards.
-
Use synthetic monitoring as a free uptime checker. 100k API test executions per month means you can ping your endpoints every minute for free.
-
Reuse one dashboard per stack. The 1,000-dashboard limit is generous, but every new dashboard adds query load. Clone a base dashboard and change the datasource or template variables instead of starting from scratch — it keeps your workspace navigable and your queries fast. Combined with the 6,000+ community dashboards you can import, one well-organized folder usually beats twenty ad-hoc boards.
Use Cases That Fit the Free Tier
1. Side-Project / Hobby API Monitoring
Spin up Grafana Alloy on your VPS, scrape your Node.js or Go API, and get dashboards, alerts, and logs—all for free. The 14-day retention is fine for catching issues as they happen.
2. Frontend Observability for React/Next.js
The Faro Web SDK gives you Core Web Vitals, error tracking, and session replay data. This is normally a paid feature in other platforms; here it’s included. Session replay captures real user sessions in your own frontend, so when a customer reports a bug, you can watch exactly what they saw instead of guessing from stack traces alone.
3. Pre-Launch Confidence for Small SaaS
Combine k6 load tests, synthetic monitoring, and metrics to prove your app can handle traffic before you launch. The free tier is enough to validate a small SaaS’s production readiness.
Pros and Cons
The Good
- Most generous permanent free tier in observability. Independent cost analysis confirms this beats competitors on raw volume.
- Full LGTM stack included. You’re not getting a crippled demo—you get Mimir, Loki, Tempo, Pyroscope, k6, synthetics, and OnCall all on one plan.
- Not a gated trial. Dashboards, alerting, Explore, 100+ data sources, and OpenTelemetry support are all fully accessible.
- Frictionless upgrade path. If you outgrow the free tier, Pro starts at $19/month with pay-as-you-go usage and 13-month retention.
- Production-grade credibility. Grafana Labs was named a Leader in the 2025 Gartner Magic Quadrant for Observability (Grafana Labs announcement).
The Not-So-Good
- 14-day retention. Metrics, logs, traces, and profiles all expire after two weeks. No long-term trending.
- Usage caps sneak up. 10,000 active series sounds like a lot until you add high-cardinality labels.
- Alerting limits. 35 rule groups and 20 rules per group cap your alerting complexity.
- Single-org, 3-user OnCall. The free tier is designed for individuals or tiny teams.
- Learning curve. PromQL, LogQL, and TraceQL are powerful but not beginner-friendly.
Alternatives Worth Considering
- Prometheus + Grafana OSS (self-hosted): Free and unlimited, but you run and maintain everything. Good for learning; bad for time.
- New Relic: Offers 100 GB data ingest per month free, but it’s agent-centric APM rather than a full LGTM stack, and the free tier has feature restrictions.
- SigNoz: Open-source, OTel-native APM, but there’s no free cloud tier—you self-host or pay.
Who Should Skip the Free Tier
If you need long-term trend analysis — capacity planning, quarterly growth charts, or compliance-grade audit trails — the 14-day retention is a dealbreaker. Teams that need metrics history measured in months should budget for the Pro tier’s 13-month retention (pricing breakdown) or self-host Grafana OSS with their own storage. Similarly, if your workload relies on high-cardinality labels (per-user or per-tenant metric dimensions), the 10,000 active series limit will force constant cardinality management.
The Verdict
Grafana Cloud’s free tier is the best deal in observability. It’s not a trial with a ticking clock; it’s a genuinely useful platform that can handle a production side project, a small SaaS pre-launch, or a serious hobby app.
The 14-day retention is the only real pain point, and it’s a reasonable trade for getting Mimir, Loki, Tempo, k6, synthetics, and OnCall for exactly $0 per month.
If you’re not using it yet, you’re leaving money on the table—or rather, saving money you didn’t need to spend.
