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 Daytona?

Ten releases in a month, all pointed at making agent sandboxes safe to run in production.

Daytona is shipping every few days through the 0.195–0.204 line, and the releases cluster into four themes: client security (PKCE replacing an embedded client secret, enforced TLS verification, stricter config permissions), cost control over running sandboxes (time-to-live, auto-pause intervals, historical metrics), observability (websocket lifecycle event subscriptions across every SDK), and API ergonomics (typed error codes, pre-signed upload and download URLs, lifecycle-aware listing). Sandbox forking and snapshot creation moved from experimental to stable in 0.202.0, and 0.204.0 adds snapshot operations by name plus outbound proxy configuration at create time.

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.

5.0

Ten releases in a month, all pointed at making agent sandboxes safe to run in production.

◆ Current state

Daytona is shipping every few days through the 0.195–0.204 line, and the releases cluster into four themes: client security (PKCE replacing an embedded client secret, enforced TLS verification, stricter config permissions), cost control over running sandboxes (time-to-live, auto-pause intervals, historical metrics), observability (websocket lifecycle event subscriptions across every SDK), and API ergonomics (typed error codes, pre-signed upload and download URLs, lifecycle-aware listing). Sandbox forking and snapshot creation moved from experimental to stable in 0.202.0, and 0.204.0 adds snapshot operations by name plus outbound proxy configuration at create time.

◆ Where it's heading

This is a platform hardening its edges rather than adding new primitives. The pattern — typed errors in every SDK, consistent daemon error codes, name-based instead of ID-only operations — is what a team does when customers have moved from experiments to workloads they need to debug and bill for. Cost and lifetime controls arriving alongside metrics points the same way: the questions being answered are how long a sandbox lives and what it costs, not what it can do.

◆ Prediction

Expect the remaining experimental surfaces to graduate next, with continued parity work so all SDKs expose the same typed errors and events. The outbound proxy and TLS enforcement suggest network policy is the active area, so egress controls are the likely next addition.
