When to stay with LlamaIndex
Documented strengths from our LlamaIndex review — switching isn't always the right call:
- Core framework is free and MIT-licensed, with roughly 25M monthly package downloads and 50k+ GitHub stars
- Parsing quality on hard documents — nested tables, charts, scanned and handwritten pages — is the product's genuine differentiator
- Free tier includes 10,000 credits/month, enough to evaluate on ~1,000 pages before paying
