OpenPing and Checkly
Monitoring as code built on Playwright: browser and API checks that live in your repo. OpenPing does the uptime part too, and then checks whether the AI in your product is answering, and answering right.
Side by side
| What | OpenPing | Checkly |
|---|---|---|
| Websites and APIs from many regions | Yes | Yes |
| Monitors as code in your repo | Yes, openping.yml | Yes, TypeScript, Terraform and Pulumi |
| Browser journeys with Playwright | Later | Yes |
| Heartbeats for scheduled jobs | Yes | Yes |
| Status pages | Yes | Yes |
| Checks your MCP servers: handshake, sign-in, tool list, changes, a safe test call | Yes | No. Checkly's MCP server lets an AI assistant run your Checkly account; it doesn't check yours |
| AI agents asked real questions on a schedule, answers judged by rules and an AI judge | Yes | Partly: its Agentic Checks can judge an AI chat by outcome, but they stop running on 1 December 2026 |
| AI gateways checked with your app's real model settings | Yes | No |
| Hidden instructions for AI caught in pages, API answers and tool lists | Yes, on by default | No |
| Go-live check: a grade and copy-paste fixes for any address, no setup | Yes | No |
| Break-it tests on your own app: poisoned files, poisoned prompts, malformed JSON | Coming, on paid plans, for apps you've proven are yours | No |
| Alerts by SMS | Yes, on paid plans | Yes |
| Alerts by WhatsApp | Yes, on paid plans | Not in its alert channels |
| Phone calls | No | Yes |
| Traces | No, on purpose | Yes, OpenTelemetry |
| Start from one URL, no code | Yes | Code first; there is a web editor too |

Pick Checkly when
Your critical paths are browser flows you already test with Playwright, or you want traces beside your checks. Checkly is excellent at both, and OpenPing doesn't run browser journeys yet.
Pick OpenPing when
Your product's risk is in its AI: an MCP server that loses a tool, a gateway that falls back to another model, an agent whose answers get worse. OpenPing checks those directly, from one URL, without writing code.
