Datadog and Grafana Cloud suit teams that already use observability dashboards, while Papertrail and Loggly suit smaller teams that want a simple start. Log volume, retention, and search frequency drive the bill more than the number of users, so measure daily volume before you choose. Splunk, Sumo Logic, Graylog, and Logz.io use quote only pricing in this comparison, so ask for a written estimate based on your real volume.

The 8 best best log management tools comparisons, in detail
Datadog
Best for: Full observability with logs, metrics, and traces
Datadog Log Management starts at $0.10 per GB ingested per month, with Standard Indexing at $1.70 per million log events per month for 15 day retention on annual billing. You can ingest all logs, archive them, and index only the logs you need for fast search, alerts, and dashboards. Flex Storage starts at $0.05 per million events stored per month for longer retention, and log forwarding costs $0.25 per GB outbound per destination per month.
- The platform includes parsing for more than 200 log sources, faceted and full text search, log based metrics, real time alerting, and archiving to AWS
- Datadog fits teams that want one observability platform, but it is less suited to teams that want a single flat monthly price.
Pros
- Ingest and index controls let you choose which logs stay searchable
- Logs connect with metrics, traces, and dashboards in one view
Cons
- Ingest plus indexing creates two charges that can be hard to predict
- Flex Logs storage does not support monitors or Watchdog Insights
Splunk Cloud Platform
Best for: Large scale search and security investigation
Splunk Cloud Platform is the managed SaaS version of Splunk, and its pricing page lists activity based, workload, or ingest pricing for unlimited users.

- Built in data filtering helps you reduce noise before it reaches the index.
- Splunk is known for its search language and its ability to handle very large volumes of machine data.
- Teams use it for application troubleshooting, IT operations, and security investigation, and Splunk Enterprise Security adds SIEM workflows on top of

Pros
- Unlimited users on Cloud Platform plans and scale to petabytes of data
- Activity based, workload, or ingest pricing gives large teams a choice of model
Cons

- The choice of pricing model adds complexity to budgeting
Sumo Logic
Best for: Cloud log analytics and SIEM use cases
Sumo Logic pricing is built around Sumo Credits, with tiered credits and Flex licensing shown on its pricing page. The page does not publish a single starting price for log analytics, so the starting price in this comparison is quote only. Flex licensing offers $0 log ingest in the vendor description, with charges for storage and for the data your searches scan.
- Log retention reaches up to 365 days on one plan, and the other plan uses customer defined retention.
- The platform includes log search and visualisation, live tail for streaming logs, ingest budgets, dashboards, and more than 400 apps and integrations.
- Security features include SIEM log ingest, an Insight Rules Engine with more than 900 out of the box rules, entity timelines, MITRE ATT&CK coverage vi
Pros
- Unlimited users across the plans shown on the pricing page
- Log analytics, SIEM, and telemetry pipeline controls sit in one platform
Cons
- No single public per GB price is shown, so costs depend on credits and scan volume
- Flex licensing bills for storage and search, which can be hard to forecast
Graylog
Best for: Self hosted control and security log work
Graylog licenses processed data volume in the active data tier, using daily volume or annual consumption in Graylog Consumption Units. Entry points on its pricing page are 10 GB per day and 100 GCUs, and device count, user count, and total stored data do not affect licensing. The page states that licenses are annual subscriptions, but the page text reviewed here does not show a dollar figure, so the starting price in this comparison is quote only.
- Graylog Open is free permanently, with no daily ingest cap, under the Server Side Public License.
- Graylog Enterprise provides log management, collection, search, data tiering, reporting, and access control.
- Graylog Security includes everything in Enterprise and adds SIEM capabilities, including maintained detection content, anomaly detection, guided inves
- Graylog fits teams that want control over deployment and a free open option to start with.
Pros
- Graylog Open is free permanently with no daily ingest cap
- Licensing is based on processed data volume, not on device count or user count
Cons
- Commercial pricing is quote only on the vendor page, with annual figures and no public monthly rate
- Self hosted deployment needs your team to run the infrastructure
Logz.io
Best for: Open source based observability on managed ELK
Logz.io pricing is based on the amount of log data you send, measured in GB, and how long you keep it, with most customers retaining log data from 3 to 90 days. The pricing page also describes consumption based pricing, where you commit to a single figure and allocate it across telemetry types. Monthly plans cost 1.2 times the annual plan, and overage is charged at 1.4 times the subscription cost.
- The page text reviewed here does not show a numeric starting rate, so the starting price in this comparison is quote only.
- Logz.io is built on open source tools, including OpenSearch, Grafana, and Jaeger, and it offers log management, infrastructure monitoring, distributed
- Data Optimization Hub can remove low value data before it is stored, and the vendor states that customers remove 32 percent of their data and costs on
Pros
- Managed OpenSearch based log management removes the work of running ELK yourself
- Data Optimization Hub, Cold Tier, and Archive and Restore help cut storage costs
Cons
- The pricing page reviewed here does not show a numeric starting rate, so you need a quote
- Overage is charged at 1.4 times the subscription cost, which can raise the bill after a spike
Papertrail
Best for: Simple cloud log aggregation for small teams
Papertrail is a cloud hosted log management service from SolarWinds, and its plans page starts at $5.00 per GB per month. The plan description lists an intuitive web based log viewer, team wide groups and searches, unlimited systems and users, encrypted logging, long term archive, a REST API, and search alerts. Transfer is measured monthly, and 1 GB is 6.6 million 100 character messages, with 50 bytes added for metadata per message.
- Archives are downloadable text files copied to Amazon S3.
- The main limit is retention.
- The Papertrail FAQ says 3 to 7 days satisfied most of its own searches, and archives cover the rest.
- That design works well for live troubleshooting, where you need to tail logs and search recent events, but it is less suited to teams that need 90 day
Pros
- Starts at $5.00 per GB per month with unlimited systems and users
- Web based log viewer, search alerts, and long term archive are included in the plan description
Cons
- Searchable retention is short, with 3 to 7 days satisfying most searches in the vendor FAQ
- Overage can continue at a 30 percent higher price per GB, up to 200 percent extra
Grafana Cloud
Best for: Loki logs beside Grafana dashboards
Grafana Cloud Logs is a fully managed log aggregation system powered by Grafana Loki. The free tier costs $0, with no credit card required, and includes 50 GB ingested per month and 14 day retention. The Pro plan has a platform fee of $19 per month, which includes 50 GB ingested per month, 30 days retention, and 8 by 5 email support.
- Usage above the included amount starts at $0.05 per GB processed, $0.40 per GB written, and $0.10 per GB retained.
- Adaptive Logs identifies commonly ingested log patterns and creates recommendations for dropping unused telemetry, which can cut log ingest by up to 5
- Because logs sit beside metrics, traces, profiles, and dashboards, you can build one view that shows a service, its logs, and its error rate together.
Pros
- Free tier includes 50 GB of logs ingested per month with 14 day retention
- Logs, metrics, and traces share one Grafana Cloud billing model with Adaptive Logs to cut ingest
Cons
- Loki indexes labels, not full log content, so high cardinality labels need care
- Logs use three meters, process, write, and retain, which can confuse budgeting

How we chose
We opened each vendor pricing page on 2026-11-12 and took the starting price from that page, or wrote quote only when the page did not show a public starting price. We used the vendor docs and plan pages for features, limits, retention, and free plan details, and we did not claim hands on testing. We included tools that cover different needs: full observability, large scale search, SIEM, self hosted control, open source based hosting, and simple cloud aggregation.

Frequently asked questions
What is the cheapest log management tool in this comparison?
Papertrail has the lowest clear starting price in this comparison, at $5.00 per GB per month, with a free plan for small volumes. Grafana Cloud also has a free tier with 50 GB per month, and Loggly Lite is free up to 200 MB per day.
How much log volume should I expect per day?
Volume varies widely by stack, but a small web service may send under 1 GB per day, while a mid sized system with many services can send 10 to 100 GB per day. Check your current log files, count GB per day for two weeks, and split the total by service.
Do I need a SIEM as well as log management?
You need SIEM features if security investigation is a main job, including alert triage, threat detection, and compliance reporting. Splunk Enterprise Security, Sumo Logic SIEM, and Graylog Security cover that need, with detection content and investigation workflows built for security teams.
What is the difference between ingest pricing and indexing pricing?
Ingest pricing charges you for the data you send to the platform, while indexing pricing charges you for the data that stays searchable. Datadog uses both, with $0.10 per GB ingested and $1.70 per million events indexed for 15 day retention.
Can I switch log management tools later?
Yes, but switching takes planning, because historical logs, saved searches, dashboards, and alert rules do not move on their own. Export your archives, save your key searches and alert definitions, and run the new tool beside the old tool for two to four weeks.
