llama_index vs PageIndex
The two are close in size: 52.6k stars for llama_index, 39.4k for PageIndex. Over the days we have tracked them llama_index moved +3% and PageIndex +15%, so PageIndex is growing faster right now.
llama_index leads on customization. PageIndex does not take any axis by a clear margin.
Stars and commit dates come from our own daily tracking. The six axes are read off each project's documentation by our review pipeline, so they describe what a project says about itself, not what we measured in its code.
Where they stand today

Six axes, head to head
Each axis runs 0 to 5. The label under a score is what that project's own docs claim, not a category average.
| Axis | llama_index | PageIndex |
|---|---|---|
Context depth How much of your codebase it sees before it answers: the open diff, the diff plus related files, or the whole repository. | ●●●●● Whole-data ingestion | ●●●●● Whole-repo analysis |
Noise control How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only. | ●●●●● Rerankers + filters | ●●●●● Basic filters/config |
Customization How far it bends to your team: custom rules, prompts, style guides, per-path config. | ●●●●● Highly extensible | ●●●●● Config file options |
Privacy Whether your code stays on your own infrastructure: fully local, self-hostable, or cloud API only. | ●●●●● Local model support | ●●●●● Self-hostable |
Model freedom Whether you can point it at any provider, or it is wired to one. | ●●●●● BYO models & keys | ●●●●● Bring-your-own |
Setup ease What it takes to get a first useful run out of it. | ●●●●● Config + API key | ●●●●● API key + install |
