TL;DR

Axiom has the most generous free tier in the category by two orders of magnitude: 500GB a month, permanently, with Cloud at $25 including 1TB. Better Stack is the cleanest bundle pricing, from $30 a month for 40GB. Grafana Cloud gives 50GB of logs free and fits if you already run Grafana. New Relic includes 100GB a month and charges $0.40 per GB after.

Top pick: Axiom (best for: Teams that want to stop rationing their logs)
Top pick price as of September 25, 2026: Axiom: From $25/mo (Cloud, platform fee); free Personal plan ($0/month, permanent)

5 tools compared: Axiom, Better Stack, Grafana Cloud, New Relic, Datadog
Better Stack (best for: Teams that want a predictable bundle rather than a usage meter): From $30/mo (Nano, Europe); free plan (3GB logs, retained 3 days)
Grafana Cloud (best for: Anyone already running Grafana dashboards): Free tier (50GB logs, 14-day retention); paid tiers scale by usage
New Relic (best for: Teams that want one platform for logs, APM and everything else): Free tier (100GB ingest/month); overage $0.40/GB; Standard, Pro, Enterprise scale up

Log management is priced by the gigabyte, which means your bill is set by how chatty your services are rather than by how many people use the tool.

That is an uncomfortable relationship: the cheapest way to cut the invoice is to log less, which is the opposite of what you want during an incident.

So the number that matters is the included volume, and the spread here is extraordinary.

Axiom's free plan takes 500GB a month. Better Stack's free plan takes 3GB. Same category, same word, a 166-fold difference.

What it is

A log management platform ingests structured and unstructured logs from your services, indexes them so you can search across sources, retains them for a period, and alerts on patterns.

Modern ones bundle traces and metrics alongside, which is where the observability label comes from.

Pricing has three moving parts and vendors emphasise whichever flatters them: ingest per gigabyte, retention per gigabyte per month, and sometimes query compute.

A cheap ingest rate with expensive retention is a common shape, and it only shows up on the second invoice.

Why it matters

Every serious incident review ends at the same question: what did the logs say. If your retention window is shorter than your detection time, the answer is nothing, and the tool has failed at the one job it was bought for.

The second reason is behavioural.

Teams on aggressive per-gigabyte pricing start sampling their logs, then dropping debug levels, then removing log lines. Each step is rational and the cumulative effect is that the expensive observability platform observes less than the free one would have.

Key features to look for

Included ingest volume

How many gigabytes a month the plan takes before overage. The single number that decides your bill, and the one the pricing page states least clearly.

Retention window

How long logs stay searchable. Thirty days is common; free tiers often drop to three. If it is shorter than your time to detect a problem, the tool cannot answer the question you will ask it.

Overage rate

What each extra gigabyte costs once you pass the allowance. New Relic publishes $0.40 per GB; Better Stack runs $0.10 to $0.35 depending on region. This is what your bill actually moves on.

Query cost

Whether searching your own data costs extra. Some platforms meter query compute separately, which turns a long incident investigation into a line item.

Structured search

Querying by field rather than grepping strings. The difference between finding the failing request in seconds and reading pages of output.

Traces and metrics alongside

Whether the same platform holds the other two pillars. Consolidating usually costs less than three vendors, but check the bundle's per-signal allowances.

Pricing

Log management is priced on ingest per gigabyte, retention per gigabyte per month, and sometimes query compute, so the included volume sets the bill more than the platform fee.

Axiom and Better Stack publish full rate cards, checked 28 August 2026: Axiom Personal is $0 a month and Cloud is a $25 platform fee, and Better Stack bundles start at $30 a month in Europe. Grafana paid tiers scale by usage, and Datadog bills ingest per GB plus $1.70 per million events indexed for 15 days on annual billing.

New Relic publishes a free allowance and $0.40 per GB of overage, while Standard, Pro and Enterprise scale up without listed prices. The cheapest credible entry with real volume is Axiom's permanent free plan.

Costs jump at Better Stack's $500 Tera bundle, on higher US and Singapore rates, past the included gigabytes, and when retention or query compute is billed apart from ingest.

Plan	Price	Best for
Axiom Personal	$0/month, permanent	500GB/mo data loading, 10 GB-hours query compute, 25GB storage
Axiom Cloud	$25/month platform fee	1TB/mo loading, 100 GB-hours query, 100GB storage
Axiom Cloud usage	Usage-based	After the included Cloud loading, query and storage
Better Stack Free	Free	3GB logs and 3GB traces retained 3 days, 30GB metrics
Better Stack Nano	$30/mo (Europe)	40GB each; US and Singapore cost more
Better Stack Tera	$500/mo	700GB, with 30-day retention on bundles
Better Stack ingest	$0.10 to $0.35/GB	Pay-as-you-go ingest, priced by region
Better Stack retention	$0.05 to $0.18/GB/mo	Pay-as-you-go retention per GB per month

Mistakes to avoid

×Comparing free tiers without reading the retention. Better Stack's free plan keeps logs for 3 days and Grafana Cloud's for 14. A 3-day window cannot answer a question raised in a Monday incident review about Friday night.

×Ignoring the region multiplier. Better Stack's Nano bundle is $30 in Europe and $105 in Singapore for the same 40GB. Vendors rarely surface this in a comparison table and it can triple the bill.

×Cutting log volume to cut the bill. It works, and it is the wrong lever: you are buying the tool precisely for the moment when you need the line you deleted. Change tiers or change vendors instead.

Expert tips

→Measure a week of real ingest before choosing. Most teams are wrong about their own volume by a factor of two, and every price here is a function of that number.

→Price the overage, not the plan. New Relic's $0.40 per GB and Better Stack's $0.10 to $0.35 tell you what a bad month costs, which the headline never does.

→Check whether querying costs extra. Axiom states query compute as its own allowance, which is honest and worth budgeting; a platform that meters it silently turns a long investigation into an invoice.

The bottom line

Axiom is the standout on economics: 500GB a month free permanently, and $25 for a terabyte.

If your logs are the thing you keep rationing, that changes the calculation more than any feature here.

Better Stack is the pick when you want a bundle you can forecast, from $30 a month, and it publishes the clearest rate card of the group.

Grafana Cloud is the obvious choice if you already live in Grafana, with 50GB free. New Relic makes sense if you want logs and APM together, and Datadog when integration breadth outweighs cost.

Frequently asked questions

Which log tool has the best free tier?

Axiom, by a very large margin: 500GB a month of data loading, permanently, with 25GB of storage and no credit card. Grafana Cloud is second with 50GB of logs at 14-day retention. New Relic includes 100GB a month. Better Stack's free tier is 3GB retained for 3 days. All checked 28 August 2026.

How is log management priced?

Almost always per gigabyte, split between ingest and retention, and sometimes query compute on top. Better Stack publishes $0.10 to $0.35 per GB ingested and $0.05 to $0.18 per GB per month retained, varying by region. New Relic publishes $0.40 per GB of overage. Datadog adds a second meter on top of ingest, charging per million log events indexed, which makes it hard to compare directly.

How long should we retain logs?

Long enough to cover the gap between something happening and someone asking about it, which in most teams is longer than they think. Thirty days is the usual paid default and a reasonable target. Free tiers at 3 or 14 days are fine for development and will not survive a real incident review.

Should logs, metrics and traces live in one platform?

Usually yes, because correlating across three vendors during an incident wastes the time you have least of. The caveat is that bundles allocate per signal, so check that the logs allowance is not being subsidised by metrics you do not send.
