[jax](https://docs.jax.dev) reports 36k GitHub stars, 3.7k forks, and 2.5k open issues, last pushed Jul 11, 2026. [PolyFuzz](https://maartengr.github.io/PolyFuzz/) has 800 stars, 72 forks, and 32 open issues, last pushed Jul 10, 2025. Figures are from public GitHub metadata via [jax's repository](https://github.com/jax-ml/jax) and [PolyFuzz's repository](https://github.com/MaartenGr/PolyFuzz). | | [jax](/tools/jax-ml-jax.md) | [PolyFuzz](/tools/maartengr-polyfuzz.md) | | --- | --- | --- | | Tagline | Composable transformations of Python+NumPy programs: differentiate, vectorize, JIT to GPU/TPU, and more | Fuzzy string matching, grouping, and evaluation. | | Stars | 35,999 | 800 | | Forks | 3,676 | 72 | | Open issues | 2,495 | 32 | | Language | Python | Python | | Adopt for | - | - | | Persona | - | - | | Runtime | - | - | | License | Apache-2.0 | MIT | | Categories | Computer Vision, Evaluation & Observability, Vector Databases | Evaluation & Observability, Vector Databases | ## Trust and health _Sourced signals - not a safety guarantee.

PolyFuzz: Fuzzy string matching, grouping, and evaluation.. See the comparison table for live GitHub stats and shared categories. ### When should I choose jax over PolyFuzz? Choose jax over PolyFuzz when License: jax is Apache-2.0, PolyFuzz is MIT; Tags unique to jax: jax; Also covers Computer Vision. ### When should I choose PolyFuzz over jax? Choose PolyFuzz over jax when License: PolyFuzz is MIT, jax is Apache-2.0; Tags unique to PolyFuzz: bert, edit-distance, embeddings, levenshtein-distance; Leaner open-issue backlog (32). ### When should I avoid jax? 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. ### When should I avoid PolyFuzz? Last GitHub push was 367 days ago (dormant maintenance, Jul 10, 2025). Validate activity before betting a new project on PolyFuzz. 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. ### Is jax or PolyFuzz more popular on GitHub? jax has more GitHub stars (35,999 vs 800). Stars measure visibility, not whether either tool fits your constraints. ### Are jax and PolyFuzz open source? Yes - both are open-source projects on GitHub (jax: Apache-2.0, PolyFuzz: MIT). ### Where can I find alternatives to jax or PolyFuzz? GraphCanon lists graph-backed alternatives at [jax alternatives](/tools/jax-ml-jax/alternatives) and [PolyFuzz alternatives](/tools/maartengr-polyfuzz/alternatives) ([jax markdown twin](/tools/jax-ml-jax/alternatives.md), [PolyFuzz markdown twin](/tools/maartengr-polyfuzz/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/jax-ml-jax-vs-maartengr-polyfuzz.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, jax or PolyFuzz? jax: Very active. PolyFuzz: 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 jax and PolyFuzz? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [jax trust report](/tools/jax-ml-jax/trust); [PolyFuzz trust report](/tools/maartengr-polyfuzz/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=jax-ml-jax`](/api/graphcanon/graph?tool=jax-ml-jax) - 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/_
