Answered from the vendors’ own pages
Auth0: How much does Auth0 cost?
Auth0 has a Free tier for up to 25,000 monthly active users (MAUs). Paid plans start at $35/month (Essentials B2C) and scale to $240/month (Professional B2C) and higher for Enterprise. Pricing scales with MAU usage.
SourceCursor: 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.
SourceAuth0: Does Auth0 include Multi-Factor Authentication?
No. MFA, RBAC (Role-Based Access Control), and premium support are not included in the free tier and require upgrading to paid Essentials plans or higher.
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.
SourceAuth0: Is Auth0 independent or part of a larger company?
Auth0 was acquired by Okta in May 2021 for $6.5 billion. It now operates as a subsidiary business unit within Okta, but maintains its own brand and operations.
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.
SourceAuth0: Who should use Auth0 vs Okta?
Auth0 is developer-focused and serves customer identity use cases (B2C). Okta serves workforce identity (B2B) and has broader enterprise features. Auth0 now serves both markets post-acquisition but maintains its developer-friendly positioning.
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.
