What is Checkly?
Checkly is wiring its CLI into the agent stack while Rocky AI pushes deeper into incident debugging.
Checkly is shipping on two coordinated tracks. The agent track exposes the full Checkly CLI as agent-callable skills with discover/read/write commands and a Copy-prompt UX in the dashboard, so coding agents like Claude Code, Codex and Cursor can stand up monitoring directly. The platform track keeps cadence with monthly digests, a fresh runtime (Playwright 1.58.2, Node 24.13.1, new packages), ICMP monitors across plans, monorepo-aware Playwright Check Suites, and a rewritten Playwright reporter.
What is Prowler?
Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?
Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.

Checkly is wiring its CLI into the agent stack while Rocky AI pushes deeper into incident debugging.
◆ Current state
Checkly is shipping on two coordinated tracks. The agent track exposes the full Checkly CLI as agent-callable skills with discover/read/write commands and a Copy-prompt UX in the dashboard, so coding agents like Claude Code, Codex and Cursor can stand up monitoring directly. The platform track keeps cadence with monthly digests, a fresh runtime (Playwright 1.58.2, Node 24.13.1, new packages), ICMP monitors across plans, monorepo-aware Playwright Check Suites, and a rewritten Playwright reporter.
◆ Where it's heading
The synthetic-monitoring product is being repackaged as something agents can configure, run, and triage. Rocky AI moved from preview to GA, then started delivering Root Cause Analysis directly into Slack/Teams/email instead of just the app. The CLI's skills system means agents can author and modify monitoring without a human in the loop. Underneath, the runtime and Playwright tooling continues to mature so the agent flows have something solid to call into.
◆ Prediction
Expect Checkly to keep extending Rocky AI into more remediation-adjacent territory — proposed fixes, PR drafts, on-call workflow integrations — and to push the CLI's agent skills toward broader agent ecosystems (more MCP coverage, more first-class supported agents). The monthly digest cadence is unlikely to change.
Prowler
7.5INFRA · APIS
Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?
◆ Current state
Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.
◆ Where it's heading
Prowler is moving from configuration checks toward telling teams what is actually exploitable now: Realtime cut the wait for detection, and threat signatures cut the wait for a new check when a vulnerability lands. The free engine keeps the mechanism, while the maintained catalog and issue triage sit in Prowler Cloud.
◆ Prediction
Expect the threat catalog to grow and exploitability issues to reach more providers or link into Realtime alerts in the next releases.
