[raptor](https://arxiv.org/abs/2401.18059) reports 1.7k GitHub stars, 233 forks, and 44 open issues, last pushed Sep 3, 2024. [cherche](https://github.com/raphaelsty/cherche) has 332 stars, 14 forks, and 4 open issues, last pushed Jun 1, 2024. Figures are from public GitHub metadata via [raptor's repository](https://github.com/parthsarthi03/raptor) and [cherche's repository](https://github.com/raphaelsty/cherche). | | [raptor](/tools/parthsarthi03-raptor.md) | [cherche](/tools/raphaelsty-cherche.md) | | --- | --- | --- | | Tagline | Recursive Abstractive Processing for Tree-Organized Retrieval | Neural Search | | Stars | 1,742 | 332 | | Forks | 233 | 14 | | Open issues | 44 | 4 | | Language | Python | Python | | Adopt for | RAPTOR employs retrieval-augmented-generation using agents and vector databases for enhanced language model efficiency. | Cherche is a Python library for implementing neural search capabilities. | | Persona | - | - | | Runtime | - | - | | License | MIT | MIT | | Categories | AI Agents, Vector Databases | Data & Retrieval, Evaluation & Observability, Vector Databases | ## Trust and health _Sourced signals - not a safety guarantee.

Validate activity before betting a new project on cherche. - Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. - Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers. - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. ## Common questions ### What is the difference between raptor and cherche? raptor: Recursive Abstractive Processing for Tree-Organized Retrieval. cherche: Neural Search. See the comparison table for live GitHub stats and shared categories. ### When should I choose raptor over cherche? Choose raptor over cherche when Tags unique to raptor: agents, clustering, framework, language-model; Also covers AI Agents; When you require an advanced processing framework based on agents and vectorized databases to improve the retrieval of information within complex data structures. ### When should I choose cherche over raptor? Choose cherche over raptor when Tags unique to cherche: bm25, flashtext, information-retrieval, natural-language-processing; Also covers Data & Retrieval, Evaluation & Observability; Cherche is a Python library for implementing neural search capabilities. ### When should I avoid raptor? Do not use RAPTOR if your application has no need for recursive abstraction or does not benefit from tree-organized information retrieval techniques. If real-time updates and dynamic data changes are critical to your workflow, consider alternatives since vector databases might have limitations in handling such scenarios. ### When should I avoid cherche? Last GitHub push was 811 days ago (dormant maintenance, Jun 1, 2024). Validate activity before betting a new project on cherche. Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough.

Stars measure visibility, not whether either tool fits your constraints. ### Are raptor and cherche open source? Yes - both are open-source projects on GitHub (raptor: MIT, cherche: MIT). ### Where can I find alternatives to raptor or cherche? GraphCanon lists graph-backed alternatives at [raptor alternatives](/tools/parthsarthi03-raptor/alternatives) and [cherche alternatives](/tools/raphaelsty-cherche/alternatives) ([raptor markdown twin](/tools/parthsarthi03-raptor/alternatives.md), [cherche markdown twin](/tools/raphaelsty-cherche/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/parthsarthi03-raptor-vs-raphaelsty-cherche.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, raptor or cherche? raptor: Dormant. cherche: Dormant. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for raptor and cherche? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [raptor trust report](/tools/parthsarthi03-raptor/trust); [cherche trust report](/tools/raphaelsty-cherche/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=parthsarthi03-raptor`](/api/graphcanon/graph?tool=parthsarthi03-raptor) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
