Stop guessing about your reliability. Start proving it.

Gremlin replaces backward-looking incident metrics with forward-looking reliability scores—so your teams can see where systems will fail, fix them first, and prove the results.

Trusted by the world's most reliable companies

The visibility challenge

You're investing millions in reliability. Can you show it's working?

When every metric in your reliability stack—incident counts, MTTR, uptime—is backward looking, you only see what already went wrong. The result: strategic decisions driven by lagging data, resilience investments that go unvalidated, and gaps that only surface after an outage.

Lagging indicators, not leading ones

MTTR and uptime tell you about past failures, not where your systems are at risk right now or where the next outage will come from.

Resilience investments go unvalidated

Redundancy, auto-scaling, disaster recovery plans—you built them, but have you tested them? The first real test is usually a production incident.

Inadequate organizational visibility

Individual teams lack standardized comparison and can't report on reliability risks and investment priorities to senior leadership.
The new reliability standard

Manage reliability the way you manage everything else—with data

Gremlin delivers a standardized, scalable way to measure, manage, and improve the reliability of your services. Instead of waiting for incidents to tell you what's broken, Gremlin shows you what will break and proves your fixes are working.

Measure

Confidence in every service

Gremlin maps dependencies, detects risks, and tests services, giving each one a reliability score: a forward-looking view of which services are resilient, which have unvalidated failure modes, and where the highest-risk gaps are right now.

Manage

Standards across every team

Standardize reliability practices by defining what "good" looks like with test suites, benchmark services against your standards, and show executives the data they need to fund the right investments.

FAQ

Common questions

We're not sure we're ready for this. Is there a minimum maturity level?

This is the most common concern we hear—and it's usually backwards. Waiting until you're "ready" for reliability engineering is like waiting until you're in shape to start exercising. Gremlin is how you get there. Built-in safety mechanisms and guided onboarding ensure you can start without risk. The real risk is waiting.

Things already fail all the time. Why would we introduce more failure?

If things are already failing unpredictably, you don't have reliability—you have uncontrolled risk. Gremlin doesn't add randomness. Our approach is engineer-driven and methodical: targeted test coverage, safe execution, controlled blast radius, and a deliberate path into production.

How is Gremlin different from chaos engineering?

Chaos engineering can mean different things to different organizations, and the word "chaos" implies randomness. Gremlin takes a structured, engineer-driven approach focused on test coverage, safety, and scaling reliability practices from development through production. The goal isn't to break things randomly—it's to give you a complete, honest picture of your reliability so you can make informed decisions about where to improve.

How long does it take to see results?

Most organizations see their first reliability scores within days of deployment. Gremlin's guided test suites and automatic risk detection mean you get actionable findings immediately—not after months of configuration. Teams typically identify their first critical gaps within the first week.

How does Gremlin integrate with our existing observability and incident management tools?

Gremlin integrates with and works alongside the tools you already use—monitoring, observability, CI/CD, and incident management platforms. It adds the proactive, forward-looking layer that those tools can't provide on their own. Your existing stack tells you what happened; Gremlin shows you what will happen.
