The Problem
The gap between what's shipping and what's monitored has never been wider.
Your agents are shipping code faster than your ops and SRE team can keep up.
Coverage gaps go undetected
AI generates code faster than you can write tests. New surfaces ship unmonitored, leaving critical paths exposed with zero visibility.
Manual monitoring doesn't scale
Ops teams can't keep pace with AI-driven deployment velocity. Every sprint outpaces what your team can manually configure and maintain.
Incidents surface too late
By the time customers report issues, the blast radius has already grown. Without proactive monitoring, you're always reacting instead of preventing.
AI-native workflow
01 Create
Go from prompt to monitor in seconds.
Checkly communicates with your agents to turn natural language prompts into fully configured tests and monitors. Describe what you want to check, and AI generates the code, picks the regions, wires up the alerts, then deploys them to Checkly.
02 Investigate
Investigate failures and performance issues with complete context.
When a test or monitor fails in Checkly, your agents can be immediately informed and instantly start investigating the failure. Use traces, logs, code, docs, and more to surface the root cause.
03 Communicate
Let agents handle communication and incident response.
Checkly enables your AI to draft incident updates, notify the right teams, and keeps your status page current. Your team focuses on fixing while Checkly handles communication.
04 Resolve
Let AI suggest fixes and rollbacks.
Don't just read an alert and find the problem — let AI suggest the fix. Get actionable remediation steps, code patches, and rollback commands tailored to your stack.

“An agent gets the page first, looks at your synthetic checks through Checkly, runs queries from metrics, logs, and traces. Things that usually take you 20 minutes, it can do in two.”
