Hi @Prashant ,
Absolutely - you can use all those applications and more! Developer Tier comes with all applications that are “Generally Available”. You can view these under “Application Access” in Control Panel. If you would like access to applications in “Beta” please contact Palantir support by raising an Issue in your instance.
For how to see the limits on Developer Tier, simply navigate to “Your Plan” in Control Panel. Checkout this post for more information.
Thanks!
