Deploy Usage Guard Collector on Cloudflare

  1. Step 1: Set up Appflare in your Cloudflare account

    Once

    Appflare installs itself into your own Cloudflare account from your browser, and runs on the free Workers plan, as Usage Guard Collector does. See what Usage Guard Collector needs on your account.

    Set up AppflareAlready have Appflare? Install Usage Guard Collector

  2. Step 2: Install Usage Guard Collector

    The install form asks you for:

    • Analytics API token

    It also has three optional settings you can leave for later.

    The form puts Usage Guard Collector behind Cloudflare Access, so only the people who use your Appflare can open it. You can switch that off.

  3. Step 3: Finish setting it up

    After the install, Appflare shows two short steps for Usage Guard Collector, on its page.

With Appflare instead of by hand

  • Nothing to build on your computerAppflare sets itself up from your browser, with no API token to create and nothing to install.
  • Updates in one clickAppflare tells you when the catalog has a new version, and Update installs it.
  • Health checksAfter every install and update, Appflare checks that the app answers.
  • It stays in your own accountEverything runs on your Cloudflare account and your plan, and Appflare records what it creates, so an uninstall removes it.

Questions

Does Usage Guard Collector run on Cloudflare's free plan?

Yes. Usage Guard Collector runs on Cloudflare's free Workers plan, and so does Appflare.

What does Usage Guard Collector create in my Cloudflare account?

Appflare creates a Worker for Usage Guard Collector and the resources it uses: D1 databases and cron triggers. Appflare records each resource it creates; an uninstall deletes them, keeping any data you choose to keep.

How do I update Usage Guard Collector?

When the catalog has a new version, Usage Guard Collector's page in Appflare says Update available. Select Update: Appflare takes a snapshot first, so you can roll back to the version before. You can also let Appflare update it automatically.

Is Usage Guard Collector open source?

Yes, under MIT. An open-source license: you may use, change and share the app on its terms. Its source code is at github.com/HowardZlh/usage-guard-collector.
