Splunk makes sense when you already run log aggregation and SIEM at serious scale and want synthetic checks living next to that data. It stops making sense the moment synthetic monitoring is the only thing you actually need, because Splunk prices its observability products separately, per host, per session, or per request, and none of those units map cleanly onto "watch a login page." Below is what Splunk Synthetic Monitoring actually charges today, what migrating a browser test looks like, and where Splunk still wins outright.
Splunk Observability Cloud sells its capabilities as separate metered products rather than one flat plan, so what you pay depends on which pieces you turn on. Pulled from splunk.com/en_us/products/pricing/observability.html on August 17, 2026:
| Plan | Price | Detail |
|---|---|---|
| Synthetic Monitoring | $1 per 10,000 uptime requests | Covers browser tests, API tests, and uptime tests, plus Lighthouse scores, Core Web Vitals, private locations, and CI/CD integration. The only line item priced by request rather than by host. |
| Infrastructure Monitoring | $15/host/mo, billed annually | Real-time hybrid cloud monitoring with 200+ integrations. Not required to run synthetic checks, but most Splunk deployments have it running already. |
| Application Performance Monitoring | $55/host/mo, billed annually | Full-fidelity trace ingest and dependency-aware service maps, sold separately from Synthetic Monitoring. |
| Real User Monitoring | $14 per 10,000 sessions | Front-end session tracking correlated with APM. A different product from Synthetic Monitoring, priced on the same per-unit model. |
A single uptime check running once a minute generates roughly 43,000 requests a month, about $4.30 at the $1-per-10,000-requests rate Splunk lists for Synthetic Monitoring on its own. That is the cheapest way into the platform. Splunk also sells three bundles on the same pricing page, Infrastructure ($15/host/mo), App & Infrastructure ($60/host/mo), and End-to-End ($75/host/mo), all billed annually and priced per host rather than per check, which only pencils out once you already have infrastructure to instrument alongside the synthetic checks.

Splunk Synthetic Monitoring runs three kinds of tests, and only one of them leaves anything portable behind.
These just ping a URL on a schedule. Copy the URL and interval into an ObserveOne URL monitor and the migration is done.
One URL, load-time and Core Web Vitals capture, nothing else to configure. Point ObserveOne Autopilot at the same URL, or build one browser check by hand; there is no script to export because there was never one to begin with.
Built by adding steps in Splunk's UI, each one identified by id, class, name, CSS path, or XPath, with optional custom JavaScript per step (per Splunk's own docs at docs.splunk.com/observability/synthetics/browser-test/). None of that exports as a runnable file. Someone has to read the step list off the screen and either rebuild the flow by hand in ObserveOne's editor or describe it to Autopilot and check the generated Playwright suite against the original steps.
Endpoint checks with response assertions. These map directly onto ObserveOne API Checks: rebuild the request and its assertions in the request builder and the coverage is equivalent.
Ranked by how closely each one replaces Splunk. Every row links to a full side-by-side breakdown.

None of this makes Splunk the wrong pick for every team. If you are already running Splunk for log aggregation or SIEM, adding Synthetic Monitoring at $1 per 10,000 requests is genuinely cheap, and having uptime, API, and browser checks sit next to the same security and infrastructure data your team already watches has real value a separate tool cannot match. Splunk's 200+ integrations, its enterprise compliance track record, and two decades in the market (founded 2003, against ObserveOne's 2024) cover ground ObserveOne does not: no SIEM, no log aggregation, no infrastructure monitoring. If synthetic checks are one line item on a security and observability platform you already pay for, Splunk is the lower-friction choice. If synthetic monitoring and test automation are the actual job and there is no existing Splunk footprint to fold them into, paying host-based prices for platform breadth you will not use is the expensive way to get there.
Usually not on its own. Splunk Synthetic Monitoring is cheap per request ($1 per 10,000), but it is one product inside a platform priced around logs, SIEM, infrastructure, and APM. Paying host-based or session-based rates for those other products to get synthetic checks makes sense only if you already use them.
Depends on the test type. Uptime tests are just a URL and interval, copy them over. Single-page browser tests are one URL with no extra configuration, rebuild them in a minute or point Autopilot at the page. Transactional browser tests are built step by step in Splunk's UI with no exportable script, so those need a manual rebuild in ObserveOne's editor or an Autopilot-generated suite checked against the original steps. API tests map directly onto ObserveOne API Checks.
Yes, and it is the safer way to do this. Keep the Splunk tests live while the equivalent ObserveOne checks run for a week or two, then compare the pass and fail history before turning the old ones off.
On its own, an uptime check running once a minute costs about $4.30 a month at Splunk's $1-per-10,000-requests rate. The cost changes once you add Infrastructure Monitoring ($15/host/mo), APM ($55/host/mo), or the bundled End-to-End tier ($75/host/mo), which is where most Splunk observability bills actually land.
If the second half of that describes your team, moving the checks over is mechanical work for two of the four test types and a rebuild for the third. Start with the uptime tests, since those migrate in minutes, and leave the transactional browser tests for last.
