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!

Closed Source Publishing Software
While not open sourced, there are several publishing/blogging platforms with core support for webmentions.
- Micro.blog can send and receive Webmentions. When you use Micro.blog to reply to a post in the timeline, Micro.blog will send a Webmention for that post if it is hosted outside of Micro.blog. When receiving a Webmention, Micro.blog will attempt to map the incoming reply to an existing Micro.blog user, otherwise it will create a special record for the external site based on its domain name.
- i.haza.website is a hosting service that can run your site on dobrado, and supports several IndieWeb building blocks including Webmention.
- Prismo is link aggregator software that began supporting Webmention in version 0.6.0rc4 
- Prismo currently only sends webmentions for posted links, not links within comments.

Web We Want
- Sample want: https://webwewant.fyi/wants/105/
Services for publishers to handle receiving & sending webmentions for their sites or using webmentions for additional services like POSSE. Alphabetical:
brid.gy is a service that sends webmentions for comments/replies, likes, and reposts on Twitter, flickr, GitHub, Mastodon, and Instagram posts. It uses original post discovery to find target links for the webmentions. GitHub repo here.
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.
It can be used to send out webmentions and pingbacks for new posts on static sites.
Telegraph is an open source project and hosted service for sending webmentions and pingbacks. You can use it to send mentions to all links on a page, or send a webmention with specific source and target.
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 a command-line tool for sending webmentions from pages discovered from arbitrary feeds (RSS, Atom, and h-feed).
Tools you can use or install to send webmentions
- Firefox add-on to send webmentions though context menu (source on Github); The original functioning addon has been removed from the Firefox site.
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
