Webmention is a web standard for mentions and conversations across the web, a powerful building block that is used for a growing federated network of comments, likes, reposts, and other rich interactions across the decentralized social web.
When you link to a website, you can send it a Webmention to notify it. If it supports Webmentions, then that website may display your post as a comment, like, or other response, and presto, you’re having a conversation from one site to another!

Bussator is a webmention receiver which publishes webmentions as comments. Its modular design supports publishing to multiple commenting systems, but currently only a plugin for Isso has been implemented. Bussator is a WSGI application, which can also be installed as a FastCGI service (that is, one doesn't need to have a webserver running all the time).
Lazymention is an open source service you can run on a Node.js server to send Webmentions from static sites. Its general purpose is to add dynamic building-block features to otherwise static websites.
mention-tech is a service that can receive webmentions on behalf of anyone via both webmention directly, and a web form on its home page.
stapibas is a self-hosted service to send and receive webmentions for websites and blogs.

webmention.app is a platform agnostic service that will check a given URL or feed for any number of content entries, discover whether there are links that support webmentions, then send the webmention to the target. It is intended for an automated workflow and includes simple instructions on how to integrate into existing workflows (using tools like IFTTT or the command line or Netlify).
Pushl is an open-source tool for sending webmentions from pages discovered from arbitrary RSS/Atom feeds
Tools you can use or install to send webmentions

Users without other simple means to send a Webmention from one site to another can use the following tool interfaces to "manually" send webmentions on their behalf:
For those with more programming knowledge there is also a method for sending webmentions with cURL.
To manually receive webmentions you can have your web server log HTTP POST requests sent to your webmention endpoint URL to a file. Then you look at the log file with your text editor and respond manually, or script it, or whatever you like. An example of how to do this with nginx is at "A static, manual system for *receiving* webmentions (and pingback) with nginx" http://superkuh.com/blog/2020-01-10-1.html
