Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Bolt.new
- The free plan is capped at 300K tokens a day and 1M tokens a month
- Pro starts at 10M tokens a month for $25, so heavy sessions are metered rather than unlimited
- Team seats are billed at $30 per member per month and tokens are not pooled across the team
- Unused tokens roll over for one additional month only, so they expire after two
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
Bolt.new: Can I use Bolt for free indefinitely?
Bolt invites users to 'Try it out and start building for free', indicating a free option is available. However, the page mentions two tiers (Standard and MaxPro) and includes a '/pricing' link, suggesting paid plans exist. Specific details about free tier limits and paid pricing are not on the main page.
SourceSemantic Kernel: What LLM providers does Semantic Kernel support?
Semantic Kernel supports OpenAI, Azure OpenAI, Hugging Face, Nvidia, and other providers through extensible model implementations.
SourceBolt.new: What are the differences between Standard and MaxPro tiers?
The page mentions both 'Standard' (described as 'Recommended for general development') and 'MaxPro' tiers in feature comparisons, but does not disclose specific differences, pricing, or what qualifies as 'general development' vs. other use cases.
SourceSemantic 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.
SourceBolt.new: Are there usage limits on the free tier?
The page does not specify what limits apply to the free tier. To obtain detailed information about free tier limits and paid plan features, you would need to visit the dedicated pricing page.
SourceSemantic 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.
