Rigor is a digital experience monitoring platform acquired by Splunk in 2020 and folded into Splunk's observability portfolio. It focuses on synthetic monitoring, performance optimization, and Core Web Vitals — primarily for enterprise teams.

How does pricing compare?

Rigor (now part of Splunk Synthetic Monitoring) uses Splunk's enterprise pricing model — typically thousands per year, scaling by check volume. Lemwatch Pro is a flat $19/mo for up to 50 sites.

Does Rigor have SEO or visual monitoring?

Rigor has some SEO-adjacent performance audits but doesn't include sitemap indexation tracking, security header scoring, broken link detection, or visual screenshot diffing. Lemwatch includes all of these.

Is Lemwatch a good Rigor alternative?

For website health monitoring at agency or SMB scale, yes — Lemwatch covers more breadth at a fraction of the cost. For Splunk-shop enterprises that need deep transaction monitoring tied to Splunk Observability, Rigor/Splunk Synthetic remains a better fit.

Can I migrate from Rigor easily?

Yes. Add your URLs to Lemwatch, configure Core Web Vitals tracking, and you're monitoring in under 15 minutes. No agents or scripts to migrate.

TL;DR

Quick Verdict

Rigor (now Splunk Synthetic) is a strong choice for enterprises already invested in Splunk's observability stack and needing deep transaction scripting.

Choose Lemwatch if you need:

Self-service signup, no sales motion
All-in-one monitoring at flat pricing
$19/mo Pro for 50 sites
Broader coverage: SEO, security, visual

Choose Rigor if you need:

Compare the workflow, not a stale checklist

Product availability, feature names and plan limits change. Use the current documentation for Lemwatch and Rigor to validate the capabilities that matter to your team.

What must the check represent: a public page, an API, or a complete authenticated journey?

Who will configure and own it: a non-technical team, developers, or both?

Which evidence do you need after an alert: request context, a script result, logs, or a customer-facing status?

This page does not treat a feature label as a permanent product fact. Confirm current coverage, implementation requirements and commercial terms with each provider before purchase.
