Resilience Testing ∙ reliability guardrails ∙ agentic remediation

Stop guessing about your reliability. Start proving it.

Most teams learn where they're fragile when things break. With Gremlin and Foresight AI, you find the risks first, get the fix, and re-test to prove it works.

New:  FORESIGHT AI

AI accelerates everything.
Foresight makes it resilient.

Supervised AI agents grounded in the Failure Atlas, Gremlin's record of how real systems fail and recover. They find your highest risks, deliver the fix for your team to approve, and re-run the test to prove the risk is gone.
The visibility challenge

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

Incident counts, MTTR, and uptime only show what already went wrong. Meanwhile, AI ships changes faster than any team can validate them.

Lagging indicators

MTTR, SLOs, and uptime show past behavior, not where you're at risk now.

Unverified resilience

Redundancy, auto-scaling, and DR plans go untested until a production incident tests them.

Disability Partially Blind Icon from Ultimate Regular set by streamlinehq.com

Organizational blindspots

Without a common standard, teams can't compare risk or report it to leadership.

Change outpaces validation

Known risks sit in a remediation backlog while new code keeps shipping.

The new reliability standard

Make reliability manageable

Gremlin gives you a standardized, scalable way to measure, manage, and improve the reliability of your services, before an incident tells you what's broken.

measure

Gain confidence in every service

Passive risk detection, dependency discovery, and resilience and chaos testing give you a forward-looking view of every service.

FAQ

Common questions

How is Gremlin Foresight AI different from AI SRE tools?

AI SRE tools help you respond to incidents faster, which means they assume the incident happens. Foresight AI tests your systems to find failures before they reach customers, then proves the fix works. One speeds up recovery. The other prevents the incident.

What is Foresight AI?

Foresight AI is Gremlin's agentic resilience product. Its supervised agents analyze and test your systems, propose fixes as config patches and IaC diffs, and re-run tests to prove each fix holds. It's grounded in the Failure Atlas, Gremlin's record of how real systems fail.

How does Gremlin integrate with our existing tools?

Gremlin works alongside your monitoring, observability, CI/CD, and incident management tools. Your existing stack tells you what happened; Gremlin shows you what could happen next.

How long does it take to see results?

Most organizations see their first reliability scores within days of deployment. AI-enabled setup and analysis, guided test suites, and automatic risk detection mean findings without months of configuration.

How is Gremlin different from chaos engineering?

Chaos engineering is where Gremlin started, but the word "chaos" implies randomness. Gremlin is structured and engineer-driven: test coverage, safety, and scaling reliability practices from development through production. The goal is an honest picture of where you're at risk and what to fix next.

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

If things already fail unpredictably, you have uncontrolled risk. Gremlin replaces it with controlled tests: targeted coverage, safe execution, a limited blast radius, and a deliberate path into production.

Is there a minimum maturity level?

No. Waiting until you're "ready" is like waiting to get in shape before you start exercising. Built-in safety controls and guided onboarding let you start safely at any maturity level.
