[lightly](https://docs.lightly.ai/self-supervised-learning/) reports 3.8k GitHub stars, 339 forks, and 92 open issues, last pushed Jul 9, 2026. [pytorch](https://pytorch.org) has 102k stars, 28k forks, and 18k open issues, last pushed Jul 11, 2026. Figures are from public GitHub metadata via [lightly's repository](https://github.com/lightly-ai/lightly) and [pytorch's repository](https://github.com/pytorch/pytorch). | | [lightly](/tools/lightly-ai-lightly.md) | [pytorch](/tools/pytorch-pytorch.md) | | --- | --- | --- | | Tagline | A python library for self-supervised learning on images | Tensors and Dynamic neural networks in Python with strong GPU acceleration | | Stars | 3,777 | 101,752 | | Forks | 339 | 28,478 | | Open issues | 92 | 18,282 | | Language | Python | Python | | Adopt for | - | - | | Persona | - | - | | Runtime | - | - | | License | MIT | Other | | Categories | Computer Vision, Model Training | Computer Vision, Data & Retrieval, Model Training | ## Trust and health _Sourced signals - not a safety guarantee.

See the comparison table for live GitHub stats and shared categories. ### When should I choose lightly over pytorch? Choose lightly over pytorch when License: lightly is MIT, pytorch is Other; Tags unique to lightly: computer-vision, contrastive-learning, embeddings, self-supervised-learning; Leaner open-issue backlog (92). ### When should I choose pytorch over lightly? Choose pytorch over lightly when License: pytorch is Other, lightly is MIT; Tags unique to pytorch: autograd, gpu, machine-learning, neural-network; Also covers Data & Retrieval; pytorch ships Docker support for self-hosted deployment. ### When should I avoid lightly? Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ### When should I avoid pytorch? Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ### Is lightly or pytorch more popular on GitHub? pytorch has more GitHub stars (101,752 vs 3,777). Stars measure visibility, not whether either tool fits your constraints. ### Are lightly and pytorch open source? Yes - both are open-source projects on GitHub (lightly: MIT, pytorch: Other). ### Where can I find alternatives to lightly or pytorch? GraphCanon lists graph-backed alternatives at [lightly alternatives](/tools/lightly-ai-lightly/alternatives) and [pytorch alternatives](/tools/pytorch-pytorch/alternatives) ([lightly markdown twin](/tools/lightly-ai-lightly/alternatives.md), [pytorch markdown twin](/tools/pytorch-pytorch/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/lightly-ai-lightly-vs-pytorch-pytorch.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, lightly or pytorch? lightly: Very active. pytorch: 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 lightly and pytorch? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [lightly trust report](/tools/lightly-ai-lightly/trust); [pytorch trust report](/tools/pytorch-pytorch/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=lightly-ai-lightly`](/api/graphcanon/graph?tool=lightly-ai-lightly) - 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/_
