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 5.48 stops waiting for the next scan: it watches AWS live and can fix what breaks.
Prowler ships a minor release every one to two weeks. 5.48.0 adds Prowler Realtime for AWS in Prowler Cloud: it reads CloudTrail events as they happen, runs a targeted check on the touched resource and then alerts, opens a Terraform pull request or fixes the resource directly, depending on each account's policy. 5.47 had reduced provider setup to one step and made Issues lead with a verdict and an attack path.

Checkly

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
6.3INFRA · APIS
Prowler 5.48 stops waiting for the next scan: it watches AWS live and can fix what breaks.
◆ Current state
Prowler ships a minor release every one to two weeks. 5.48.0 adds Prowler Realtime for AWS in Prowler Cloud: it reads CloudTrail events as they happen, runs a targeted check on the touched resource and then alerts, opens a Terraform pull request or fixes the resource directly, depending on each account's policy. 5.47 had reduced provider setup to one step and made Issues lead with a verdict and an attack path.
◆ Where it's heading
Prowler is moving from a periodic scanner toward a response system: partial re-scans in 5.44, exploitability verdicts in 5.46-5.47, and now event-driven detection with reversible auto-remediation. The paid cloud tier carries most of this, with the open scanner feeding it.
◆ Prediction
Expect Realtime to extend to Azure or GCP event feeds and more checks to gain automatic fixes.
