[quant.cpp](https://github.com/quantumaikr/quant.cpp) reports 399 GitHub stars, 44 forks, and 11 open issues, last pushed Apr 26, 2026. [anubis-oss](https://devpadapp.com/leaderboard.html) has 198 stars, 12 forks, and 4 open issues, last pushed Jun 18, 2026.

Contributions to its codebase are welcomed. ## Decision facts: anubis-oss - **Pricing:** freemium - The tool is free and open-source with no monetary costs for usage or distribution. - **Requirements:** Min 8 GB RAM - **Adopt for:** Anubis-oss, specifically tailored for Apple Silicon devices using Swift, is distinguished by its focus on local large language model evaluation and testing within the macOS environment. - **License detail:** GPL-3.0 license ensures that any derivative works related to anubis-oss must also be open source under the same licensing terms. ## Choose when ### Choose quant.cpp if… - quant.cpp is primarily C; anubis-oss is Swift. - License: quant.cpp is Apache-2.0, anubis-oss is GPL-3.0. - Requirements: Requires a C compiler compatible with quant.cpp source code.. - Tags unique to quant.cpp: delta-compression, embeddable, gguf, kv-cache. - quant.cpp ships Docker support for self-hosted deployment. - Use quant.cpp when you need extended context for LLM inference in a lightweight, embeddable environment with no external dependencies. ### Choose anubis-oss if… - anubis-oss is primarily Swift; quant.cpp is C. - License: anubis-oss is GPL-3.0, quant.cpp is Apache-2.0. - Pricing: The tool is free and open-source with no monetary costs for usage or distribution.. - Requirements: Min 8 GB RAM. - Tags unique to anubis-oss: apple-silicon, benchmarking, gpu, inference. - Also covers Evaluation & Observability. - When developing and evaluating large language models intended to run natively on Apple Silicon hardware. ## When NOT to use quant.cpp - Avoid using quant.cpp for projects requiring non-C language support or frameworks since it strictly operates within the context of pure C. - Do not use quant.cpp in environments where rapid runtime performance is paramount and additional compile-time overhead introduced by its unique compression techniques may cause delays. ## When NOT to use anubis-oss - If your development does not involve Apple Silicon or macOS environments as Anubis-oss is tightly integrated with these platforms. - When preferring a language other than Swift, since Anubis-oss depends on this for its operations. ## Common questions ### What is the difference between quant.cpp and anubis-oss? quant.cpp: LLM inference with extended context using C. anubis-oss: Local LLM Testing & Benchmarking for Apple Silicon.

Stars measure visibility, not whether either tool fits your constraints. ### Are quant.cpp and anubis-oss open source? Yes - both are open-source projects on GitHub (quant.cpp: Apache-2.0, anubis-oss: GPL-3.0). ### Where can I find alternatives to quant.cpp or anubis-oss? GraphCanon lists graph-backed alternatives at [quant.cpp alternatives](/tools/quantumaikr-quant-cpp/alternatives) and [anubis-oss alternatives](/tools/uncsoft-anubis-oss/alternatives) ([quant.cpp markdown twin](/tools/quantumaikr-quant-cpp/alternatives.md), [anubis-oss markdown twin](/tools/uncsoft-anubis-oss/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/quantumaikr-quant-cpp-vs-uncsoft-anubis-oss.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, quant.cpp or anubis-oss? quant.cpp: Slowing. anubis-oss: Steady. 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 quant.cpp and anubis-oss? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [quant.cpp trust report](/tools/quantumaikr-quant-cpp/trust); [anubis-oss trust report](/tools/uncsoft-anubis-oss/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=quantumaikr-quant-cpp`](/api/graphcanon/graph?tool=quantumaikr-quant-cpp) - 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/_
