Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cursor

  • Cannot work fully offline; AI features require internet connection
  • Local models require requests to route through Cursor's backend, not true localhost support
  • Free tier capped at 2,000 completions per month
  • Codebase indexing uploads code chunks to compute embeddings, with file caching handled server-side

Semantic Kernel

  • Steep learning curve for advanced features
  • Documentation focuses on Azure cloud services
  • Configuration complexity for multi-model scenarios
  • Requires understanding of AI/LLM concepts

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.

Source
Semantic Kernel: What LLM providers does Semantic Kernel support?

Semantic Kernel supports OpenAI, Azure OpenAI, Hugging Face, Nvidia, and other providers through extensible model implementations.

Source
Cursor: 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.

Source
Semantic Kernel: Can I run Semantic Kernel locally?

Yes. Semantic Kernel supports local models through Ollama, LMStudio, and ONNX for complete data control and offline operation.

Source
Cursor: 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.

Source
Semantic Kernel: Is Semantic Kernel free?

Yes. Semantic Kernel is MIT-licensed open source and completely free. You only pay for external LLM APIs you use.

Source
Cursor: 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.

Source
Cursor: 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.

Source
Cursor: 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.
