The following page lists the browsers supported by the Palantir platform and the platform's endpoint network requirements.
The following table lists browser support by device. Note that not all Palantir applications are designed to work on mobile devices; the mobile table below applies only to applications that are mobile-friendly.
For best results, use Google Chrome or Microsoft Edge if possible. We fully support any version of the browsers listed below released within the past year. Older browser versions are partially supported up to the past two years, and browser versions released over two years ago are unsupported.
| Browser | Desktop | Mobile |
|---|---|---|
| Google Chrome | Fully supported | Fully supported |
| Microsoft Edge | Fully supported | Fully supported |
| Apple Safari | Not supported | Fully supported |
| Mozilla Firefox | Limited support: Critical bug fixes only for versions released within the last six months | Not supported |
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.
