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 Jackett?
Jackett ships daily, and every release is tracker definitions chasing sites that moved
Jackett cuts a release most mornings, each one a batch of indexer definition edits generated straight from the commit log. The work is uniform: new alternate domains for trackers that relocated, category mappings added or corrected, selectors repaired after a site changed its markup, and the occasional indexer removed when it goes dark. Recent releases also switched two trackers to API key authentication and added a public DHT crawler to another.

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.
Jackett
5.0INFRA · APIS
Jackett ships daily, and every release is tracker definitions chasing sites that moved
◆ Current state
Jackett cuts a release most mornings, each one a batch of indexer definition edits generated straight from the commit log. The work is uniform: new alternate domains for trackers that relocated, category mappings added or corrected, selectors repaired after a site changed its markup, and the occasional indexer removed when it goes dark. Recent releases also switched two trackers to API key authentication and added a public DHT crawler to another.
◆ Where it's heading
Nothing about the application itself is changing in this window — the engine is stable and the product is the definition catalog. That makes the cadence a maintenance signal rather than a development one: the release rate tracks how fast the tracker ecosystem churns its domains and layouts, not how fast Jackett is building. The only structural movement is individual trackers migrating from scraped HTML to native APIs, which reduces the breakage surface where it happens.
◆ Prediction
Expect the daily definition-maintenance cadence to hold unchanged, since it is driven by external site churn rather than a roadmap. Further trackers moving to torznab or API key authentication would gradually cut the selector-repair volume.
