[caffe](http://caffe.berkeleyvision.org/) reports 35k GitHub stars, 18k forks, and 1.2k open issues, last pushed Jul 31, 2024. [jvector](https://github.com/datastax/jvector) has 1.7k stars, 155 forks, and 45 open issues, last pushed Jul 10, 2026. Figures are from public GitHub metadata via [caffe's repository](https://github.com/BVLC/caffe) and [jvector's repository](https://github.com/datastax/jvector). | | [caffe](/tools/bvlc-caffe.md) | [jvector](/tools/datastax-jvector.md) | | --- | --- | --- | | Tagline | Caffe: a fast open framework for deep learning. | JVector: the most advanced embedded vector search engine | | Stars | 34,574 | 1,731 | | Forks | 18,458 | 155 | | Open issues | 1,209 | 45 | | Language | C++ | Java | | Adopt for | - | - | | Persona | - | - | | Runtime | - | - | | License | Other | Apache-2.0 | | Categories | Computer Vision, Vector Databases | Vector Databases | ## Trust and health _Sourced signals - not a safety guarantee.

Validate activity before betting a new project on caffe. - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. ## When NOT to use jvector - 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 caffe and jvector? caffe: Caffe: a fast open framework for deep learning.. jvector: JVector: the most advanced embedded vector search engine. See the comparison table for live GitHub stats and shared categories. ### When should I choose caffe over jvector? Choose caffe over jvector when caffe is primarily C++; jvector is Java; License: caffe is Other, jvector is Apache-2.0; Tags unique to caffe: c++, deep-learning, vision; Also covers Computer Vision. ### When should I choose jvector over caffe? Choose jvector over caffe when jvector is primarily Java; caffe is C++; License: jvector is Apache-2.0, caffe is Other; Tags unique to jvector: ann, java, knn, search-engine. ### When should I avoid caffe? Last GitHub push was 710 days ago (dormant maintenance, Jul 31, 2024). Validate activity before betting a new project on caffe. 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 jvector? Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. ### Is caffe or jvector more popular on GitHub? caffe has more GitHub stars (34,574 vs 1,731). Stars measure visibility, not whether either tool fits your constraints. ### Are caffe and jvector open source? Yes - both are open-source projects on GitHub (caffe: Other, jvector: Apache-2.0). ### Where can I find alternatives to caffe or jvector? GraphCanon lists graph-backed alternatives at [caffe alternatives](/tools/bvlc-caffe/alternatives) and [jvector alternatives](/tools/datastax-jvector/alternatives) ([caffe markdown twin](/tools/bvlc-caffe/alternatives.md), [jvector markdown twin](/tools/datastax-jvector/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/bvlc-caffe-vs-datastax-jvector.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, caffe or jvector? caffe: Dormant. jvector: Very active. 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 caffe and jvector? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [caffe trust report](/tools/bvlc-caffe/trust); [jvector trust report](/tools/datastax-jvector/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=bvlc-caffe`](/api/graphcanon/graph?tool=bvlc-caffe) - 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/_
