When you prefer a tool that does not automatically capture decisions and context, and you want full control over what is stored and retrieved. If you are working in an environment where zero-configuration tools are not suitable, and you require extensive customization options. ### Is synto or cortex-memory more popular on GitHub? synto has more GitHub stars (255 vs 8). Stars measure visibility, not whether either tool fits your constraints. ### Are synto and cortex-memory open source? Yes - both are open-source projects on GitHub (synto: MIT, cortex-memory: MIT). ### Where can I find alternatives to synto or cortex-memory? GraphCanon lists graph-backed alternatives at [synto alternatives](/tools/kytmanov-synto/alternatives) and [cortex-memory alternatives](/tools/skullfire07-cortex-memory/alternatives) ([synto markdown twin](/tools/kytmanov-synto/alternatives.md), [cortex-memory markdown twin](/tools/skullfire07-cortex-memory/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/kytmanov-synto-vs-skullfire07-cortex-memory.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, synto or cortex-memory? synto: Active. cortex-memory: Slowing. 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 synto and cortex-memory? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [synto trust report](/tools/kytmanov-synto/trust); [cortex-memory trust report](/tools/skullfire07-cortex-memory/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=kytmanov-synto`](/api/graphcanon/graph?tool=kytmanov-synto) - 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/_
