Best Datadog Alternatives in 2026 (Free & Paid)

Datadog is excellent. It's also expensive. A growing team with 10 services, 500 GB of logs per month, and 5 engineers can easily pay $2,000-3,000/month. Many teams are looking for alternatives that cover their actual needs without the enterprise price tag.

TL;DR: For pure log management, LogFlow ($19-149/month flat) is the best Datadog alternative. For open-source self-hosted, Grafana Loki. For high-volume structured events, Axiom. For full APM at lower cost, New Relic. Choose based on what you actually use Datadog for.

Why Teams Leave Datadog

Unpredictable bills — per-host, per-GB, per-user pricing multiplies across services
Complexity — massive product surface with hundreds of integrations, steep learning curve
Over-featured — paying for APM, infrastructure, synthetics, SIEM, and security when you only need logs
Agent overhead — the Datadog agent runs on every host, using CPU and memory

1. LogFlow — Best for Log Management

Best for: Teams that primarily need log search, alerting, and anomaly detection.

LogFlow is purpose-built for log management. It uses ClickHouse for sub-millisecond search, includes automatic anomaly detection (no threshold configuration), AI-powered log explanations, trace correlation, and error grouping.

Free: 500 MB/month, 3 days retention
Starter: $19/month — 10 GB, 14 days
Growth: $49/month — 100 GB, 30 days
Pro: $149/month — 500 GB, 90 days

The entire pricing model is flat — no per-host fees, no per-user surcharges (up to the plan limit). Start free in under 2 minutes.

2. Grafana Loki — Best Open Source Option

Best for: Teams with infrastructure expertise who want to self-host.

Grafana Loki is the open-source log aggregation backend from Grafana Labs. Unlike ELK, Loki indexes only metadata (labels) and stores the raw log content in object storage (S3, GCS). This makes it cheaper to operate at scale.

Cost: Free (self-hosted), ~$0.50/GB/month on Grafana Cloud
Pros: Integrates natively with Grafana dashboards and Prometheus metrics, very cost-effective at scale
Cons: Requires Kubernetes expertise to run well, limited search capabilities compared to full-text search engines, no built-in anomaly detection

If your team already runs Grafana and Prometheus, adding Loki is a natural extension. If you're starting fresh, the operational burden is significant.

3. Logtail (Better Stack) — Best All-in-One Alternative

Best for: Teams that want logs + uptime monitoring + incident management in one platform.

Better Stack acquired Logtail and built it into a broader observability suite. You get log management (ClickHouse-based, fast search) plus uptime monitoring, incident response, on-call scheduling, and status pages.

Free: 1 GB/month, 3 days
Paid: Starts at $25/month, scales with volume and users
Pros: Unified platform, modern UI, good integrations
Cons: Per-seat pricing adds up, limited anomaly detection vs. LogFlow

4. New Relic — Best for APM + Logs

Best for: Teams that need APM traces and infrastructure metrics alongside logs, but want to escape Datadog pricing.

New Relic offers a generous free tier (100 GB/month) and charges $0.30/GB above that. It has full APM (transaction traces, flamegraphs), infrastructure monitoring, and browser monitoring — comparable to Datadog but with a different pricing model.

Free: 100 GB/month data ingest, 1 user
Full platform: $99/user/month + $0.30/GB after free tier
Pros: Full observability suite, good AI features, FedRAMP authorized
Cons: Per-user pricing is expensive for large teams, UI complexity

5. Axiom — Best for High-Volume Event Data

Best for: Teams with very high log volumes (TBs per month) or who want to query structured events with SQL.

Axiom is a data platform for event logs, traces, and metrics built on Apache Arrow. It supports SQL queries, extremely high ingest rates, and long retention at low cost.

Free: 500 MB/day (generous free tier)
Paid: Starts at $25/month, $0.10/GB above free tier
Pros: Very fast SQL queries, excellent for structured data, good for security logs
Cons: Less focus on developer workflow, fewer built-in alert templates, newer product

6. Papertrail — Best for Simplicity

Best for: Small teams or solo developers who want basic log aggregation without complexity.

Papertrail is the simplest paid log management tool. One stream of all your logs, basic text search, email/Slack alerts. No learning curve.

Free: 50 MB/month
Paid: Starts at $7/month (1 GB)
Pros: Extremely simple, syslog support
Cons: Limited search, no anomaly detection, expensive at high volumes

How to Choose

Need	Best choice
Log management only	LogFlow
Open source, self-hosted	Grafana Loki
APM + logs	New Relic
All-in-one with uptime	Better Stack / Logtail
High-volume SQL queries	Axiom
Maximum simplicity	Papertrail

Making the Switch

If you're migrating from Datadog specifically for logs:

Identify what Datadog features you actually use day-to-day
If it's primarily log search and alerts: try LogFlow free
Run in parallel for 2 weeks — keep Datadog as fallback
Once confident, remove the Datadog agent from your logging pipeline

Frequently Asked Questions

What is the cheapest Datadog alternative?

For log management, Grafana Loki is free if you self-host. Among managed services, LogFlow's free tier (500 MB/month) and Starter plan ($19/month) are among the cheapest. Papertrail starts at $7/month but becomes expensive above 8 GB.

Do any Datadog alternatives have anomaly detection?

LogFlow includes automatic anomaly detection on all paid plans. New Relic and Better Stack have alerting systems that can be configured to detect anomalies but require manual threshold setup. Grafana Loki and Axiom don't include built-in anomaly detection.

Can I export my Datadog logs before canceling?

Datadog allows you to export logs via the Logs API. Before canceling, set up a migration period where you send logs to both Datadog and your new provider in parallel. This ensures continuity and gives you time to verify the new setup works correctly.

Is self-hosting Grafana Loki really free?

The software is free but infrastructure isn't. A production Loki setup requires Kubernetes, object storage (S3 or GCS), Grafana, and ongoing operational work. Teams frequently underestimate the total cost — dedicated engineers, cloud storage bills, and downtime risk. Managed services are often cheaper when you account for engineering time.
