Can I ask what sort of libraries you're using for the canvas-in-page-browser-selector? Is it server or client side? The technology here is spectacular. Great job!

Thanks for your kind words. The stack is a mix of both. Browser runs on the server and sends updates to the client via websocket. Then it is painted on the client. On the client-side a part of noVNC js library is used to capture input and is sent to the browser running on the server.

Pretty slick. Could be the seed of a lightweight Browserling competitor, if you could scale it economically.

Cool concept, but name collision: Sieve has been the name of a server-side mail filtering language for quite some time. https://en.wikipedia.org/wiki/Sieve_%28mail_filtering_langua...

Glad that you liked the concept. Wasn't aware of the unfortunate name collision. I am open to suggestions. Thanks!

This is very awesome! The implementation is different to what I expected (or to what I would have done). They seem to run a browser on the server and let the user interact with it to choose DOM elements to monitor for changes. I would have just taken a screenshot (perhaps with http://urlbox.io/ or perhaps with CutyCapt) and allowed the user to draw boxes over the screenshot. Then repeatedly screenshot the site and wh…

I'm been working on http://imnosy.com for a while, and thought about that approach, but ran into difficulties when slight variations to the screen were made. Right now, we're using a diff engine. Sieve looks pretty rad though. Will check that out. Fun space :)
