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

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.
MTTR, SLOs, and uptime show past behavior, but not how your systems respond to future failures or where you’re at risk now.
Reliability efforts like redundancy, auto-scaling, and disaster recovery plans go untested until there’s a production incident.
Individual teams lack standardized comparison and can't report on reliability risks and investment priorities to senior leadership.
Gremlin gives you 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.
Gremlin combines passive risk detection, dependency discovery, and resilience and chaos testing to give you a forward-looking view of service and application resilience.
Define your reliability baseline with test suites, empower teams to perform their own testing, then benchmark services against your standards to give executives the data to fund the right investments.
Combine AI-powered expert recommendations with automated testing and reliability tracking to fix risks quickly, continuously verify results, and show measurable improvements.

In high-velocity environments, reliability can't be an afterthought.
"Reliability Intelligence equips SRE and performance teams with deep, real-time insights—enabling early detection of reliability regressions, faster root cause isolation, and proactive remediation without disrupting release velocity."

Safety controls, blast radius management, and halt conditions for safely testing in live environments.
Reliability for every layer of the stack: Bare metal, on-prem, multi-cloud, and serverless.
Used by global companies across finance, SaaS, retail, media, and more—including 4 of the 5 largest US banks.
Embedded engineers work alongside your teams to build your reliability practice and help you succeed.
Not a side project. Every line of code, every hire, every roadmap decision is dedicated to making our customers more reliable.
Gremlin maintains 99.999% availability by using Gremlin to test, manage, and improve Gremlin.
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.
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.
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.
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.
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.
