The "ngrok" tunnel is closed. Dig a "zrok" tunnel next time!

Indeed, the free plan for ngrok does have limitations. There are several other free tunneling tools available, so let me introduce them to you:

1. LocalTunnel
   Similar to ngrok, this is a tool for exposing local servers to the outside. It is easy to set up and free to use.
   - Official site: LocalTunnel

2. localhost.run
   A service that uses SSH tunnels to expose local servers.
   It is simple and effective.
   - Official site: localhost.run

3. Expose
   An open-source tunneling tool written in Golang that is free to use.
   It is useful for testing webhooks and exposing local development servers.
   - Official site: Expose

As for free tunneling tools that can handle large applications,
the following are available:

1. PageKite
   An open-source tunneling software that has a free plan. It is particularly useful when you need a sustainable connection.

2. Cloudflare Tunnel
   You can use Cloudflare's free plan to expose local servers to the outside. The setup is a bit complex, but it is free to use.

3. Zrok
   An open-source tunneling tool that has a free plan. It is particularly
   suitable for sharing backends.

You might want to try these tools as well. Is there any one
you would like to try? I can also help with specific setup methods,
so please feel free to let me know.

Certainly!
Below are the steps to set up tunneling using Zrok.

Step 1: Check the official Zrok website

1. Access the official Zrok website.

2. Look for the download section and check the links for the latest binary files.

Step 2: Check the GitHub repository

1. Access the Zrok GitHub repository.

2. Look for the latest release tags or binary files.

If you cannot find the latest link, please
report the issue on the GitHub Issues page or contact the support team.

Please let me know if you have any other questions or need further support.

Since SageMaker Studio Lab typically uses the x86_64 (or amd64) architecture,
I recommend downloading the x86_64 version.

The following is a notebook-style guide for installing and using Zrok using the x86_64 version:

Zrok Installation and Usage Steps

Cell 1: Downloading Zrok

[ python ]

# Zrokのバイナリをダウンロード
!wget https://github.com/openziti/zrok/releases/download/v1.0.2/zrok_1.0.2_linux_amd64.tar.gz -O zrok.tar.gz

Cell 2: Extracting the binary

Extract the downloaded tar.gz file.

[ python ]

# バイナリを解凍
!tar -xzf zrok.tar.gz

Cell 3: Granting execution permissions

Grant execution permissions to the extracted binary.

[ python ]

# 解凍されたバイナリに実行権限を付与
!chmod +x zrok

Cell 4: Configuring Zrok

Configure Zrok.

[ python ]

# Zrokの設定
!zrok enable [あなたのトークン]

That message is normal! Since it says "the zrok environment was successfully enabled...", it indicates that the Zrok environment has been correctly enabled.
Let's move on to the next step.

Cell 5: Sharing resources

Tunnel your resources.

[ python ]

# 公開リソースの共有
!zrok share public http://localhost:8888

With this, you can now expose your local host port (e.g., 8888) to the outside world via a tunnel using Zrok.

Please try running each cell in order. If any errors occur or if you have any other questions, please let me know. I am here to support you!

Indeed, according to the official zrok website, the free plan has the following limitations:

• Free Plan
  5GB/day traffic, 2 environments, 5 shared backends (2 reserved), 5 private access frontends.

• Paid Plan
  20GB/day traffic, 5 environments, 10 shared backends, 10 private access frontends.

While the zrok free plan has limits on daily traffic and the number of available backends and frontends, it does not appear to have a trial period limit.

You're very welcome! I'm glad I could help.
I'm happy to hear that tunneling with Zrok is working well for you. If you have any more
questions or need support in the future, please feel free to reach out anytime.

Have a wonderful day! 🚀😊

😄 < It's been almost a year since I switched from "ngrok" to "zrok",
and I have never once hit the daily bandwidth limit, even on the free plan.
Even after four hours of intensive image generation, the traffic stays
under 5GB. I highly recommend it!
