Answered from the vendors’ own pages
LlamaIndex: How much does LlamaIndex (LlamaParse) cost?
LlamaIndex offers a Free plan with 10K monthly credits at $0/month. The Starter plan is $50/month for 40K credits plus pay-as-you-go overage up to 400K total. The Pro plan is $500/month for 400K credits. Credits are priced at 1,000 credits for $1.25.
SourceSolidJS: Is SolidJS free?

LlamaIndex: Is LlamaIndex free?
Yes, LlamaIndex offers a free plan with 10K monthly credits, basic parsing, 5 concurrent jobs, and support for up to 100 users with no upfront payment required.
SourceSolidJS: Is SolidJS just React without the virtual DOM?
The syntax is similar but the model is not. Solid components run once and reactivity is fine-grained, so patterns that are correct in React can be wrong in Solid.
LlamaIndex: What are LlamaIndex's concurrent job limits?
The Free and Starter plans allow 5 concurrent jobs. The Pro plan increases this to 20 concurrent jobs. Enterprise plans offer custom configurations with 5x higher rate limits.
SourceSolidJS: Why is SolidJS fast?
It compiles away much of the framework and updates individual DOM nodes directly, rather than re-rendering components and diffing a virtual DOM.
