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
You're investing millions in reliability. Can you show it's working?
Every metric in your reliability stack—incident counts, MTTR, uptime percentages—only tells you 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.
Manage reliability the way you manage everything else—with data
Gremlin is the reliability management platform that gives engineering organizations a standardized, scalable way to measure, manage, and improve the reliability of their services. Instead of waiting for incidents to tell you what's broken, Gremlin shows you what will break—and proves your fixes are working.
Confidence in every service
Gremlin tests your services, detects hidden risks, and gives each one a reliability score. For the first time, you get a forward-looking view of which services are resilient, which have unvalidated failure modes, and where the highest-risk gaps are right now.
Reliability scores for every service, tracked over time
Failure tests that prove your resilience mechanisms actually work
Spots configuration drift and hidden vulnerabilities automatically
Maps dependencies so you can see hidden failure paths
Standards across every team
Standardize reliability practices across hundreds of teams and thousands of services. Define what "good" looks like with test suites, benchmark every service against your standards, compare teams, and give executives the reporting they need to fund the right investments.
Standardized test suites define and enforce reliability standards
Organization-wide benchmarking and team comparison
Executive-ready reporting that makes reliability measurable, comparable, and fundable
Works across bare metal, on-prem, multi-cloud, and serverless

Common questions
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.
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.
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.
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.
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.
