  • Inspect your browser fingerprint and environment
  • Measure latency and packet loss from locations around the world

Deploy One IP 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 One IP does. See what One IP needs on your account.

    Set up AppflareAlready have Appflare? Install One IP

  2. Step 2: Install One IP

    One IP needs no keys or settings from you.

    It also has 10 optional settings you can leave for later.

    One switch on the form puts One IP 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 a short step for One IP, 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.

What it needs on your account

Nothing beyond a Cloudflare account on the free Workers plan.

Questions

Does One IP run on Cloudflare's free plan?

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

What does One IP create in my Cloudflare account?

Appflare creates a Worker for One IP. Appflare records each resource it creates; an uninstall deletes them, keeping any data you choose to keep.

How do I update One IP?

When the catalog has a new version, One IP'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 One IP open source?

Yes, under AGPL-3.0-only. An open-source license: you may use, change and share the app on its terms. Its source code is at github.com/zhihui-hu/one-ip.
