Checkly on Cloudflare

Synthetic uptime, API, and browser checks using Cron Triggers, Browser Rendering, Queues, and D1.

Checkly · observability

Synthetic monitoring, API checks, browser checks, and alerting.

How it would work

A URL goes in, an API-ready result comes out. These are the stages the request flows through.

  1. map 01

    Map the rented workflow

    Identify the small-team job that actually needs replacing.

  2. build 02

    Assemble the Cloudflare loadout

    Pick the primitives that cover the core data, compute, auth, and delivery path.

  3. ship 03

    Publish the useful version

    Release a deployable build with limits, setup notes, and maintenance tradeoffs.

Concrete jobs it does

If you're paying Checkly for any of these, the proposed build would let you stop.

  • Cover the small-team workflow people actually rent the SaaS for
  • Expose a simple, deployable API
  • Persist the right data in D1 and the right artefacts in R2
  • Stay maintainable by one or two engineers

Config knobs

will build
  • + The core workflow small teams actually use every week.
  • + A deployable Cloudflare-native version with clear setup steps.
  • + Basic auth, data storage, admin screens, and operational visibility.
  • + A writeup that explains the useful limits and maintenance burden.
will not build
  • - A pixel-perfect clone of the SaaS being replaced.
  • - Enterprise governance, compliance guarantees, or managed support.
  • - Every advanced feature that only large teams need.
  • - A promise that replacing the rented tool is always the right call.

Checkly on Cloudflare

This candidate asks whether Checkly can be replaced by a smaller owned workflow on Cloudflare without pretending to cover the whole enterprise product.

What this is

Checkly is compelling because monitoring is mostly scheduled checks, results, assertions, and alerts.

How we would build it

Use Browser Rendering, D1, Email Workers, Queues, Workers to cover the core workflow without adding rented infrastructure.

The honest limit

Strong for API checks, page checks, and small-team uptime monitoring. It will not match every Checkly Playwright workflow, private location, or enterprise alert integration immediately.
