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 Skipper?
Skipper fixes two silent data-loss bugs — body truncation on large requests and multi-value header drops.
Skipper is in a steady maintenance phase: the two meaningful releases this period are correctness fixes for a silent body-truncation bug in the io matcher (large request bodies dropped silently beyond the max buffer size) and a cookie-deleting bug where modRequestHeader/modResponseHeader only applied regex rewrites to the first value of a multi-valued header. Both are proxy correctness issues where the visible behavior was incorrect responses, not errors.

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.
Skipper
6.3INFRA · APIS
Skipper fixes two silent data-loss bugs — body truncation on large requests and multi-value header drops.
◆ Current state
Skipper is in a steady maintenance phase: the two meaningful releases this period are correctness fixes for a silent body-truncation bug in the io matcher (large request bodies dropped silently beyond the max buffer size) and a cookie-deleting bug where modRequestHeader/modResponseHeader only applied regex rewrites to the first value of a multi-valued header. Both are proxy correctness issues where the visible behavior was incorrect responses, not errors.
◆ Where it's heading
The release cadence is high but the surface area of recent changes is narrow: dependency bumps, documentation corrections, and targeted correctness fixes. Skipper is a mature, production-stable L7 proxy — the development pattern reflects that. The v0.28.x branch is moving ahead of the v0.27.x LTS track simultaneously.
◆ Prediction
The entries don't show architectural moves in the near term. The next meaningful Skipper releases will likely continue in this pattern: correctness fixes for edge-case proxy behaviors that bite production users, with occasional dependency security updates.
