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 folds it into three host-priced Observability Cloud tiers, and the tier that actually runs a browser check is the most expensive one. Below is what those tiers cost, what migrating a browser test looks like, and where Splunk still wins outright.
Splunk Observability Cloud is sold as three bundled tiers rather than one flat plan, and each tier up adds more of what a synthetic-monitoring buyer actually wants. Pulled from splunk.com/en_us/products/pricing.html#observability on September 29, 2026:
| Plan | Price | Detail |
|---|---|---|
| Infrastructure | $15/host/mo, billed annually | Infrastructure monitoring, Log Observer Connect, Network Explorer, and synthetic uptime checks. No APM and no API or browser synthetic checks at this tier. |
| App & Infra | $60/host/mo, billed annually | Everything in Infrastructure, plus APM with Always On Profiling and synthetic API monitoring. Still no browser checks. |
| End-to-End | $75/host/mo, billed annually | Everything in App & Infra, plus real user monitoring and synthetic browser monitoring. This is the only tier that runs a browser-based synthetic check. |
There is no way to buy just synthetic monitoring from Splunk any more. Uptime pings ride along in the cheapest tier at $15/host/mo, but API checks need the $60/host/mo App & Infra tier, and browser checks only exist in the $75/host/mo End-to-End tier, bundled in alongside APM and real user monitoring whether you want those or not.

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, you are likely already paying for the Infrastructure tier, and uptime checks ride along in it for free. 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 no longer sells synthetic monitoring separately: browser checks only come in the $75/host/mo End-to-End tier, bundled with APM and real user monitoring whether you use them or not. Paying host-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.
It depends which checks you need. Uptime pings are covered by the $15/host/mo Infrastructure tier. Add API checks and you need the $60/host/mo App & Infra tier. Browser checks only show up at the top, the $75/host/mo End-to-End tier, along with APM and RUM you may never touch.
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.
