![]() If there is some code that you are using to manage the executed instances that is missing from the Playwright Server, we would be happy to consider adding it upstream. So putting Playwright server into the cloud sounds like a clear win to us, by good margin. They reside next to the browser, are accessible to the Playwright server and can be exposed to the user over the wire. We can be efficient with the resources written by the browser, including downloads, recently added videos and work-in-progress traces.Protocol traffic drops, instead of 4-8 roundtrips for each click you get 1.Switching to this model gives WebKit and Firefox for free We support non-Chromium browsers uniformly.This enables us (and you, cloud providers) operate much more efficiently: I believe Selenoid is now doing that already. When we are reasoning about it internally, we refer to the model where the k8s cluster includes Playwright Server and uses it to launch the browser. Thanks a lot for your time and input, much appreciated. the initial handshake or similar) and forward the websocket frames to either the custom Playwright websocket or the vanilla CDP socket Develop a custom websocket server that can differentiate between Playwright and Puppeteer clients (through e.g.Modify launchServer to not launch a browser but use an existing one through CDP (should be possible as internally Playwright still uses the vanilla CDP websocket).In my scenario I have full control over the websocket server consumed by pptr/pw clients but the server itself has to connect to existing browsers through vanilla CDP (playwright cannot be used to launch them). Having that said, I wonder what the best course of action would be if someone would be determined enough to develop a custom websocket server compatible with Playwright wire protocol and vanilla CDP clients. Note: I really appreciate the efforts of the Playwright team and the project contributors and can understand why switching to a custom wire protocol was desired. ![]() The CDP websocket has always felt like the underlying and unifying standard or common denominator that all CDP based automation frameworks could interface with. The following worked prior to Thanks a lot for the quick response on that matter. My use-case is to have a single websocket url which exposes a fleet of chromium browsers by proxying the websocket connections (similar to browserless.io) and both puppeteer & playwright being able to connect to it and control the browsers. My question would be if there's still a way to use nnect with the traditional CDP websocket URLs or if there are pointers on how to best write a translation layer to accomplish that. I also noticed through logging that the new wire protocol looks much different from the regular CDP chatter. connect with other original CDP websocket servers anymore (it will hang here). V1.4.0 introduced the new "New Client / Server Wire protocol", since then it's not possible to use. connect to a vanilla browser websocket URL (either created through launching Chrome with -remote-debugging) or using Puppeteer). Its patent portfolio comprises over 1,750 issued patents and patent applications.Apologies if this has been asked before but I didn't find anything. Its products include Chromium Single Cell Gene Expression, Chromium Single Cell Gene Expression Flex, Chromium Single Cell Immune Profiling, Chromium Single Cell assay for transposase accessible chromatin (ATAC), Chromium Single Cell Multiome ATAC + Gene Expression, Visium Spatial Gene Expression, Visium Spatial Proteogenomics and Xenium In Situ Gene Expression. Its Visium platform enables researchers to understand the spatial positions of biological analytes within tissues at high resolution. Its Chromium platform includes its Chromium X Series, Chromium Connect and legacy Chromium Controller instruments, microfluidic chips and related consumables, enables throughput analysis of individual biological components. The Company's integrated platform solutions include instruments, consumables and software for analyzing biological systems.
