Answered from the vendors’ own pages
Cursor: What's included in Cursor's free tier and what are its limits?
The free Hobby plan provides 2,000 completions per month and 50 slow premium requests, with access to basic autocomplete features. Codebase-wide indexing and the Composer multi-file editor are not available on the free plan.
SourceCursor: Does Cursor require an internet connection to edit code?
While Cursor can open and edit files locally, its AI features including autocomplete, chat, agents, and codebase-aware reasoning require internet access to cloud-hosted models.
SourceCursor: Can I use Cursor with local models running on my machine?
Cursor can integrate with local models, but requests still route through Cursor's backend for prompt building. True localhost mode without external endpoints is not supported. The paid plan ($20+/month) is required to use local models.
SourceCursor: What privacy controls does Cursor offer?
Cursor offers Privacy Mode (enabled on paid Team plans) which prevents customer data from being used for model training, with zero data retention agreements with all AI providers. When disabled, Cursor may use codebase data to improve features.
SourceCursor: What are the differences between Pro and Pro+ plans?
Pro ($20/month) includes unlimited completions and 500 fast premium requests, while Pro+ ($60/month) provides 3x those request limits, priority feature access, and extended Agent capabilities.
SourceCursor: Does Cursor support SSO and on which plan?
SSO with SAML/OIDC is included on Teams Standard ($40/user/month) and higher plans, with full team administration and audit logs.
