The following page lists the browsers supported by the Palantir platform and the platform's endpoint network requirements.
The Palantir platform is fully supported on Google Chrome and Microsoft Edge versions released within the last six months. Palantir's mobile-friendly applications require Google Chrome, Microsoft Edge, or Apple Safari.
Palantir will provide critical bug fixes for users of Mozilla Firefox versions released within the last six months. For best results, use Google Chrome or Microsoft Edge if possible.
As the primary Palantir platform frontend is a web application, users are recommended to use supported browsers for optimal operation.
However, in rare cases, users with unusual networking set-ups may experience issues, despite using a supported browser.
In order to aid debugging, this page documents some of the assumptions that Foundry makes about the client endpoint's network set-up.
Many in-platform applications use WebSockets ↗ for communication between the client and the server, and the Palantir platform assumes that WebSocket connections are possible.
Some proxy servers require special configuration or a software upgrade in order to support WebSocket connections. If users connect to Palantir platform via a proxy that does not support WebSockets, large parts of the platform may become unusable.
HTTP/2 support is vital for the seamless performance of the Palantir platform, as it helps facilitate the handling of a significant number of concurrent requests from Foundry applications to the backend.
Note that proxy servers can downgrade HTTP/2 connections to HTTP/1.1, which can make Foundry applications slow to the point of obstructing usability.
If you are encountering slowness when using the Palantir platform and your connection to the platform goes through a proxy, you should investigate the possibility that your proxy is downgrading the connection.
