How can custom applications be built on the Palantir platform?

• A. Only by writing full code in Java
• B. Using the developer toolchain, OSDK, Slate, or Workshop for low-code solutions
• C. Only via external connectors
• D. By compiling APT models

Answer: (B)

Custom applications on Palantir are built using a flexible set of development tools. The platform provides a developer toolchain that includes the Open Source Developer Kit for creating custom logic and integrations, Slate for building user interfaces, and Workshop for low-code app development. This combination lets teams either write full code to customize behavior or assemble apps quickly with low-code components, all inside Foundry with built-in data access and governance. It’s not limited to Java alone, nor does building apps require only external connectors or APT models. The supported approach is to use these tools to design and deploy the desired application within the Palantir environment.
