Open-Source Browser Agent for autonomously performing complex tasks on the web
Argus is a lightweight monitor to notify of new software releases via Gotify/Slack/other messages and/or WebHooks.
Argus will query websites at a user defined interval for new software releases and then trigger Gotify/Slack/Other notification(s) and/or WebHook(s) when one has been found. For example, you could set it to monitor the Argus repo (release-argus/argus). This will query the GitHub API and track the "tag_name" variable. When this variable changes from what it was on a previous query, a GitHub-style WebHook could be sent that triggers something (like AWX) to update Argus on your server.
