With feedless, you can create RSS feeds from most websites, or refine existing feeds. Feeds are created in an interactive builder, and may be improved using elaborate filters and plugins. Integration to 2rd parties like telegram is build-in. Its highly customizable and even JavaScript based websites are supported. There is zero-risk, cause all sources are available on github and you can host it yourself.
