Deploy Quickinbox 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 Quickinbox does. See what Quickinbox needs on your account.

    Set up AppflareAlready have Appflare? Install Quickinbox

  2. Step 2: Install Quickinbox

    Quickinbox needs no keys or settings from you.

    Appflare generates a value for you: Push private key (VAPID).

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

    One switch on the form puts Quickinbox behind Cloudflare Access, so only the people who use your Appflare can open it.

  3. Step 3: Finish setting it up

    After the install, Appflare shows three short steps for Quickinbox, 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 Quickinbox run on Cloudflare's free plan?

Yes. Quickinbox runs on Cloudflare's free Workers plan, and so does Appflare.

What does Quickinbox create in my Cloudflare account?

Appflare creates a Worker for Quickinbox and the resources it uses: D1 databases and R2 buckets. It also uses Email Routing. Appflare records each resource it creates; an uninstall deletes them, keeping any data you choose to keep.

How do I update Quickinbox?

When the catalog has a new version, Quickinbox'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 Quickinbox 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/DivinPrince/quickinbox.
