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 Merge?
Merge is becoming the governance layer for agent tool access, not just a unified data API.
Merge ships a weekly digest split across three lines: the original unified API (HRIS, ATS, CRM, accounting, file storage, ticketing), Agent Handler for AI agent connectors, and Gateway for LLM routing. The unified-API half reads as a maintenance grind — every week is dominated by SharePoint, SAP SuccessFactors, Workday and Dayforce sync reliability, pagination and mapping fixes. All of July's directional news came from the other two lines, ending with hundreds of generic MCP connectors folded into the Agent Handler catalog and an AI Guardrails surface with PII detection.

Checkly
0.6INFRA · APIS
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.
Merge
6.3INFRA · APIS
Merge is becoming the governance layer for agent tool access, not just a unified data API.
◆ Current state
Merge ships a weekly digest split across three lines: the original unified API (HRIS, ATS, CRM, accounting, file storage, ticketing), Agent Handler for AI agent connectors, and Gateway for LLM routing. The unified-API half reads as a maintenance grind — every week is dominated by SharePoint, SAP SuccessFactors, Workday and Dayforce sync reliability, pagination and mapping fixes. All of July's directional news came from the other two lines, ending with hundreds of generic MCP connectors folded into the Agent Handler catalog and an AI Guardrails surface with PII detection.
◆ Where it's heading
The unified API is being maintained, not expanded — new objects arrive at a trickle (expense reports in early July) while the bulk of each week goes to sync stability across existing connectors. Attention has moved to sitting between agents and the tools they call: Merge now offers auth, access control, governance and guardrails over connectors it did not build. Gateway is moving the same way, from a routing product to multi-tenant infrastructure customers resell, via Embedded Routing Stack, bring-your-own keys and per-customer complexity classifiers.
◆ Prediction
Expect the guardrails surface to deepen — PII detection and pre-run/post-run rule labels shipped in the same month, and the generic MCP connectors currently arrive without the tool safety hints Merge applied to its own catalog. The likely next step is extending that governance tooling to the imported MCP servers.
