How we choose
How we choose
We considered 14 synthetic monitoring tools and kept 6 for this list. We reviewed vendor pricing pages, billing notes and help pages between 28 Oct and 2 Nov 2026, and we checked every price again on 2 Nov 2026. We judged each tool on the work an ecommerce team runs: a checkout flow, a search flow, a login flow and the API calls behind the cart.
We scored each tool, as set out in how we score, on 5 criteria for a store with a small technical team. Browser check quality and failure evidence carried 30 points. Run pricing and cost clarity carried 25 points. Location choice carried 15 points. Alert channels carried 15 points. Setup effort for non specialist staff carried 15 points. The weights add to 100.
Checkout run budget
Runs are counted for a 30 day month, one check, one location, with no retries.
| Check interval | Runs per month | What it means on listed allowances |
|---|---|---|
| Every 1 minute | 43,200 | Past every free allowance here; needs a paid run pool |
| Every 5 minutes | 8,640 | Fits inside Grafana Cloud free browser executions, past Checkly Starter alone |
| Every 15 minutes | 2,880 | Fits inside Checkly Starter at 3,000 browser runs |
| Every 30 minutes | 1,440 | Past Checkly Hobby free at 1,000 runs; fits inside Checkly Starter |
Checkly
Best for: Ecommerce teams with a developer who can own Playwright checks in the code base.
Checkly lists a free Hobby plan with 1,000 browser check runs, 10,000 API check runs and 10 uptime monitors Checkly pricing. Its Starter plan costs $24 per month on annual billing and includes 3,000 browser runs, 25,000 API runs and 50 uptime monitors from 6 locations, while Team costs $64 per month on annual billing with 12,000 browser runs, 100,000 API runs and 22 locations Checkly pricing. Prices checked 2 Nov 2026.
For a store, the fit is the workflow. Checkout, search and login checks live in the same repository as the store code, get reviewed like code and can run on each release as well as on a schedule. The limit is arithmetic: retries and extra locations each count as runs, so a flaky checkout check burns the monthly pool fast.
Pros:
- Playwright checks double as release tests for the same flows
- Clear run allowances and overage rates on the pricing page
- Private locations start on Team for checks inside a network
Cons:
- Starter covers only 6 locations and has no private locations
- Browser check overage on Starter costs $6.50 per 1,000 extra runs
- The Hobby plan is hard capped and checks stop when runs run out
Price: Checkly pricing lists Starter at $24 per month on annual billing, checked 2 Nov 2026.
Skip it if: Nobody on the team writes or reviews code. Pingdom or Site24x7 will be easier to set up with a recorder.

Datadog Synthetic Monitoring
Best for: Stores that already run Datadog for apps, logs or infrastructure.
Datadog lists browser tests at $12 per 1,000 test runs per month on annual billing, or $18 on demand, and API tests at $5 per 10,000 test runs on annual billing Datadog pricing. Its pricing notes state that one browser test run covers a transaction of 25 steps, and that a test with 50 steps counts as 2 runs on each execution Datadog pricing. Prices checked 2 Nov 2026.
The value is context. When a checkout test fails, the same account holds the traces, logs and real user data for the same minutes, so a team can move from the failed step to the slow service behind it. The risk is cost shape: every location and every run is billed, and a long checkout flow counts double once it passes 25 steps.
Pros:
- Failed browser tests link to traces and logs in the same account
- Recorder and self maintaining tests cut script upkeep
- API, browser, mobile app and network tests share one product
Cons:
- Per run billing rises with each location, step block and shorter interval
- A 50 step checkout flow counts as 2 runs per execution, not 1
- Logs, APM and real user monitoring are billed as separate products
Price: Datadog pricing lists browser tests at $12 per 1,000 runs on annual billing, checked 2 Nov 2026.
Skip it if: You want a flat monthly bill you can state in advance. Checkly and Pingdom both price a small store setup more plainly.
[Datadog pricing](https://www.datadoghq.com/pricing/?product=synthetic-monitoring) lists browser tests at $12 per 1,000 runs on annual billing, checked 2 Nov 2026.
New Relic Synthetics
Best for: Stores that already use New Relic and want synthetics beside APM and browser data.
New Relic lists a free tier with 100 GB of data ingest a month, one free full platform user and 500 synthetic checks a month New Relic pricing. Its Standard edition includes 10,000 synthetic checks a month, and extra checks cost $0.005 per check New Relic pricing. Core users cost $49 per user per month, and data past the free 100 GB costs $0.40 per GB on the original data option New Relic pricing. Prices checked 2 Nov 2026.
New Relic covers more monitor types than most rivals here, including ping, simple browser, scripted browser, step monitors built without code, API tests, certificate checks and broken link checks. Ping monitors sit outside the check allowance, which helps a store watch many plain endpoints at no extra check cost. The free 500 checks, though, cover little more than an hourly checkout check.
Pros:
- Step monitors let non developers build simple flows without code
- Ping monitors do not use the paid check allowance
- Synthetics sit beside APM, browser and log data in one account
Cons:
- Free tier holds only 500 synthetic checks a month
- Full platform and core user fees stack on top of check and data costs
- Standard edition caps full platform users at 5
Price: New Relic pricing lists extra synthetic checks at $0.005 per check past the edition allowance, checked 2 Nov 2026.
Skip it if: Your store team is not already on New Relic. The user and data pricing model takes longer to learn than a single purpose tool.

Grafana Cloud Synthetic Monitoring
Best for: Teams that already write k6 scripts or run Grafana dashboards.
Grafana lists a free tier for synthetic monitoring with 100,000 API test executions and 10,000 browser test executions a month Grafana pricing. Its Pro tier carries a platform fee of $19 per month that includes the same execution allowances, then pay as you go pricing of $5 per 10,000 API executions and $50 per 10,000 browser executions Grafana pricing. Prices checked 2 Nov 2026.
That free allowance is the largest here by a wide margin. A store can run a checkout check every 15 minutes from several locations and stay inside the free browser pool for months. Checks are written as k6 scripts, and the same scripts can feed performance work. The trade off is the working style: there is no recorder path, and browser executions past the allowance cost ten times the API rate.
Pros:
- Largest free allowance in this list for both API and browser checks
- k6 scripts can be shared with performance testing work
- Checks, metrics, logs and traces sit in one Grafana Cloud account
Cons:
- Browser executions cost $50 per 10,000 past the allowance, ten times the API rate
- Checks are written as scripts, which shuts out non technical staff
- Enterprise tier needs a minimum commit of $25,000 per year
Price: Grafana pricing lists synthetic browser testing from $50 per 10,000 executions plus the $19 per month platform fee on Pro, checked 2 Nov 2026.
Skip it if: Your team wants a recorder and plain plan names. Pingdom gives a store team a simpler first week.
[Grafana pricing](https://grafana.com/pricing/) lists synthetic browser testing from $50 per 10,000 executions plus the $19 per month platform fee on Pro, checked 2 Nov 2026.
Pingdom
Best for: Store teams that want transaction checks without writing scripts.
Pingdom lists synthetic monitoring from $16.50 per month on annual billing, and its calculator shows that step as 10 uptime checks, 1 advanced check and 50 SMS alerts for $198 per year Pingdom pricing. The synthetic plan includes transaction monitoring, page speed monitoring and uptime monitoring, with email and SMS alerting and public status pages Pingdom pricing. Prices checked 2 Nov 2026.
Pingdom is the simplest start in this list for a store team without a spare developer. A transaction check is built by recording steps in the browser, not by writing a script, and page speed results sit beside the flow results. The limit sits in the entry step: 1 advanced check covers the checkout, but search and login flows need a higher step.
Pros:
- Transaction checks need no code, so store staff can help keep them current
- Page speed checks sit in the same plan as flow checks
- Unlimited users help when several staff need alert access
Cons:
- Entry step includes only 1 advanced check for all store flows
- No free plan, only a trial, unlike Checkly and Grafana Cloud
- Real user monitoring is billed apart, from $16.50 per month
Price: Pingdom pricing lists synthetic monitoring from $16.50 per month on annual billing, checked 2 Nov 2026.
Skip it if: You plan to run checkout, search and login checks from day one. The 1 advanced check limit pushes you up the price steps at once.
[Pingdom pricing](https://www.pingdom.com/pricing/) lists synthetic monitoring from $16.50 per month on annual billing, checked 2 Nov 2026.
Site24x7
Best for: Stores that want synthetic checks inside a wider monitoring suite.
Site24x7 lists plans from $9 per month, and its website monitoring pages list a Web Perf step from $36 per month with 40 monitors, 8 locations and 8 transaction monitors at 1 minute polling Site24x7 pricing. Its pricing notes state that real browser monitors use run based pricing, where each monitor run in each location counts as a check Site24x7 pricing. Prices checked 2 Nov 2026.
For a store that also watches servers, apps and a blog, one suite can be cheaper than three single tools, and checks run from more than 130 locations. A transaction monitor is classed as an advanced monitor, so the advanced monitor count matters more than the headline monitor total.
Pros:
- Transaction monitors are included in Web Perf rather than sold per run at list rates
- More than 130 check locations, the widest choice in this list
- Website, server and app monitoring share one account and one bill
Cons:
- Real browser runs in each location count as separate checks on run based pricing
- A 30 second website poll needs two basic licences, per its pricing notes
- Transaction monitors use the advanced monitor allowance, which is small on entry plans
Price: Site24x7 pricing lists Web Perf from $36 per month, checked 2 Nov 2026.
Skip it if: You only need checkout checks and want the shortest path to a working alert. Checkly or Pingdom will get a small store live faster.
[Site24x7 pricing](https://www.site24x7.com/site24x7-pricing.html) lists Web Perf from $36 per month, checked 2 Nov 2026.
Buyer questions
Which synthetic tool is cheapest for an ecommerce site?
Grafana Cloud free covers 10,000 browser executions a month at no cost, enough for a checkout check every 15 minutes from 3 locations Grafana pricing. For a paid plan, Checkly Starter at $24 per month is the lowest price here built around browser checks.
How many checkout checks does a store need?
Start with three flows: checkout, search and account login. Add product page and cart checks once those three stay stable for a month. Each flow needs its own check and run budget, so three flows at 5 minute intervals from one location use 25,920 runs a month. That total decides your tier on per run pricing.
What evidence should a failed check give you?
Ask for a screenshot of the failed step, the page timing for that run and the exact step that failed. Checkly and Datadog both attach step level detail to browser failures, which lets a developer tell a payment fault from a slow page Datadog pricing. Without step detail, your team reruns the flow by hand to find the fault.
Which tool fits a store with no developer?
Pingdom and Site24x7 both let staff build a transaction check without writing a script, and New Relic adds step monitors built without code New Relic pricing. Checkly and Grafana Cloud expect scripts. If nobody can own a script, pick the recorder based tool.
