Observability Cost Comparator

Compare up to five observability stacks on monthly and annual cost using the rates you enter.

At a glance

Observability Cost Comparator is a free client-side calculator that compares up to five monitoring stacks (hosts, custom metrics, log ingest and retention) on monthly and annual cost using rates you enter. No vendor prices, no signup; every number runs in your browser from visible assumptions.

Stacks to compare (2–5)

Monthly and annual observability cost comparison from user-entered rates
Stack	Hosts	Metrics	Ingest	Retention	Monthly	Annual

Estimates from your inputs. Monthly ingest = daily GB × 30; retained GB = daily GB × retention days. Cheapest badges are computed from your rates.

Why Use This Observability Cost Comparator?

Compare up to five observability stacks side by side: host fees, custom metrics, log ingest and retention, each priced from the rates you enter.

Monthly and annual totals per stack with per-component cheapest badges (hosts, metrics, ingest, retention), so you see which option wins each line item.

Delta versus the cheapest stack (for example '+$93.00/mo (+37.7%)') from visible workload inputs and a fixed 30-day-month model.

Copyable summary for your decision doc; both worked examples use the same inputs as the calculator. 100% client-side, no signup.

How to Use Observability Cost Comparator

Name your stacks

Add two to five stacks and label each one (for example 'Vendor quote A') so the comparison stays readable.

Enter the workload and each stack's rates

For every stack enter hosts, $/host, custom metrics per host, $ per 1,000 metrics, log GB/day, $/GB ingest, retention days and $/GB-month retained — always the vendor's quoted rates for the same workload.

Compare and copy the verdict

Run the comparison for monthly and annual totals, per-component cheapest badges and the delta versus the cheapest stack, then copy the summary into your decision doc.

Worked example: Two Monitoring Stacks on One Workload

The comparator multiplies each entered rate by the workload — hosts, 1,000-metric blocks, 30-day-month ingest GB, and retained GB (GB/day × retention days) — then sums the four components for each stack.

Input: stack rates + shared workload Source

Stack A 'Log-first': 10 hosts at $15/host; 500 custom metrics/host at $5 per 1,000; 20 GB/day ingest at $0.10/GB; 30-day retention at $0.02/GB-mo. Stack B 'All-in-one': 10 hosts at $9/host; 500 custom metrics/host at $8 per 1,000; 20 GB/day ingest at $0.30/GB; 30-day retention at $0.05/GB-mo.

Output: monthly + annual totals per stack Processed

Log-first: $150.00 hosts + $25.00 metrics + $60.00 ingest + $12.00 retention = $247.00/mo ($2,964.00/yr). All-in-one: $90.00 + $40.00 + $180.00 + $30.00 = $340.00/mo ($4,080.00/yr). Cheapest: Log-first by $93.00/mo (+37.7%). Component winners: hosts All-in-one; metrics, ingest, retention Log-first.

Specification	Details
Inputs & Outputs	Form parameters (up to 5 stacks) → on-page comparison table + copyable summary
Execution Mode	100% client-side in-browser (client) — no network calls, no signup, no data leaves the page
Cost Components	Hosts · Custom metrics (per 1,000) · Log ingest ($/GB) · Log retention ($/GB-month)
Worked Example — Log-first	10 hosts @ $15/host + 500 metrics/host @ $5 per 1,000 + 20 GB/day @ $0.10/GB + 30-day retention @ $0.02/GB-mo = $247.00/mo ($2,964.00/yr)
Worked Example — All-in-one	10 hosts @ $9/host + 500 metrics/host @ $8 per 1,000 + 20 GB/day @ $0.30/GB + 30-day retention @ $0.05/GB-mo = $340.00/mo ($4,080.00/yr)
Example Verdict	Log-first is cheapest by $93.00/mo (+37.7%); component winners: Hosts All-in-one; Metrics, Ingest, Retention Log-first
Price Claims	None — every rate is user-entered; no vendor pricing stored or claimed. Monthly ingest = GB/day × 30; retained GB = GB/day × retention days.

Frequently Asked Questions

How do I compare observability costs across different tools?

Enter each tool's quoted rates — per host, per 1,000 custom metrics, per GB of log ingest and per GB-month of retention — for the same workload, and the comparator returns each stack's monthly and annual total side by side. Rates come from your own contracts or quotes, so the comparison is like-for-like.

Does the observability cost comparator use real vendor prices?

No. Every rate is entered by you; the tool ships no vendor pricing and makes no vendor price claims, so results reflect your own quotes rather than a price list we maintain. That keeps the comparison honest and current.

What cost components does it compare?

Four components: host fees, custom metric fees, log ingest, and log retention. Each component is computed from your entered rate and workload, then summed into a monthly total and an annual total for every stack.

Can I compare more than two monitoring tools at once?

Yes. The comparator supports up to five stacks side by side, each with its own name, workload and rates, with per-component cheapest badges and a delta versus the cheapest stack.

Methodology

Costs are calculated from the metrics, logs and traces you enter using the rates you supply. Both worked examples use the same deterministic arithmetic as the calculator.
