Webhook site

Using Webhooks, you can connect services with eachother. For instance: You can install the Webhooks Add-on to Gravity Forms on your WordPress website. You can then define 0 to many Webhooks. Each Webhook delivers the form data in the required form (JSON/ Form fields) to any desired URL.

To test the data that is generated, there is this great Webhook Site service. On visiting, you get an URL target for your Webhook. This target URL is then used in the Webhook with the Gravity Form. Upon submitting the form, you can see the data generated on the Webhook.Site webpage.

Gliffy diagram & flowcharting

I am using Gliffy a lot. It is a great graphic tool (free Chrome extension) to create flowcharts, UML diagrams, network diagrams and much more. Very important is the rubber-banding support: when you connect objects using their red indicated connections (during drawing), these connections are maintained wherever you drag the objects.

Outgoing port tester: PortQuiz.net

I needed to test whether some ports were enabled or blocked. This tool/ service is great: It simply accepts any port request and tells you if it succeeded. From the PortQuiz page:

This server listens on all TCP ports, allowing you to test any outbound TCP port.

You have reached this page on port 80.
Your network allows you to use this port. (Assuming that your network is not doing advanced traffic filtering.)

Network service: http
Your outgoing IP: 86.93.90.146

Test a port using a command

$ telnet portquiz.net 80 
Trying ...
Connected to portquiz.net.
