Scheduling pages, availability rules, and booking workflows.

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 Calendly 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

D1

Track crawl jobs, pages, status, users, limits, and API keys.

Durable Objects

Coordinate realtime state, locks, sessions, or per-customer actors.
KV tool 03
KV

Cache settings, lightweight metadata, and fast lookup tables.
Queues tool 04
Queues

Fan out background jobs so crawls can retry and continue after the first request.
Workers tool 05
Workers

Public API, routing, auth checks, rate limits, and orchestration glue.
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.

Calendly on Cloudflare

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

What this is

Scheduling is valuable but the core workflow is small: availability, booking, conflict checks, and reminders.

How we would build it

Use D1, Durable Objects, KV, Queues, Workers to cover the core workflow without adding rented infrastructure.

The honest limit

Strong for founder, consultant, and small-team booking workflows. Calendar provider edge cases and enterprise routing should stay out of v1.
