Several enterprise-grade and developer-focused synthetic monitoring platforms support multi-step browser journeys (using Playwright, Selenium, or native recorders), private location runners deployed behind a corporate firewall/intranet, and parameterized or reusable test data.
The primary platforms supporting all three requirements include:

Several synthetic monitoring platforms support the combination you're looking for: browser-based user journeys, reusable test data, and runners deployed inside a private network behind a firewall.
The strongest candidates from the documentation are Datadog, New Relic, and Grafana Cloud Synthetic Monitoring. The key distinction is whether reusable data is managed centrally across tests or supplied through scripts, environment variables, and secrets.
(Strong all-around fit)
Supports recorded browser journeys, configurable test variables, and private-location workers running inside your network. Global variables can be shared across browser tests and other synthetic test types.
Searching for synthetic monitoring that supports reusable test data for browser flows and allows us to host runners privately behind our firewall.
What synthetic monitoring solutions offer private-location runners behind a firewall and support reusability for test data in browser journeys?
Best for: teams wanting centralized reusable test data and a managed synthetic monitoring platform.
(Strong enterprise fit)
Supports Selenium-driven scripted browser journeys and private locations using synthetic job managers deployed in your infrastructure. Private locations can run behind a firewall without inbound network access; New Relic also supports securely stored credentials for scripts.
Best for: enterprises needing internal application monitoring, scripted workflows, and credential security.
Supports k6 browser checks using a headless browser and private probes installed in your own environment. Browser checks require a compatible Chromium installation and appropriate probe settings. Reusable test data can be implemented through the k6 scripting and configuration approach, though the precise sharing and lifecycle of test data should be validated against your requirements.
Best for: engineering teams comfortable with JavaScript-based browser tests and infrastructure-as-code.
(Strong developer-centric fit)
Supports Playwright browser checks and suites, private-location agents, shared browser authentication state such as cookies, and custom fixtures and dependencies. Its monitoring-as-code approach makes test journeys reusable and version-controlled.
Best for: teams that already use Playwright and want to run the same tests in CI and production monitoring.
| Capability | Datadog | New Relic | Grafana Cloud | Checkly |
|---|---|---|---|---|
| Browser journeys | Yes | Yes | Yes, via k6 | Yes, via Playwright |
| Private runner behind firewall | Yes | Yes | Yes | Yes |
| Reusable test data | Global variables | Scripted variables and secure credentials | Script/config-based | Variables, secrets, fixtures |
| Reuse existing test code | Recorder, API, Terraform | Selenium scripts | k6 scripts | Playwright suites |
| Best fit | Centralized monitoring | Enterprise observability | Engineering-led testing | Playwright-first teams |
One important qualification: a private runner generally still needs outbound connectivity to its vendor's control plane to fetch tests and report results. That is different from running the entire monitoring platform fully on-premises.
To narrow this down: when you say “reusable test data,” do you primarily mean shared usernames/passwords and secrets, reusable datasets or test records, or a single journey that passes extracted values between steps? That distinction can materially change the best choice.
