NornicDB has more GitHub stars (843 vs 376). Stars measure visibility, not whether either tool fits your constraints. ### Are oasysdb and NornicDB open source? Yes - both are open-source projects on GitHub (oasysdb: Apache-2.0, NornicDB: MIT). ### Where can I find alternatives to oasysdb or NornicDB? GraphCanon lists graph-backed alternatives at [oasysdb alternatives](/tools/edwinkys-oasysdb/alternatives) and [NornicDB alternatives](/tools/orneryd-nornicdb/alternatives) ([oasysdb markdown twin](/tools/edwinkys-oasysdb/alternatives.md), [NornicDB markdown twin](/tools/orneryd-nornicdb/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/edwinkys-oasysdb-vs-orneryd-nornicdb.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, oasysdb or NornicDB? oasysdb: Dormant. NornicDB: 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 oasysdb and NornicDB? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [oasysdb trust report](/tools/edwinkys-oasysdb/trust); [NornicDB trust report](/tools/orneryd-nornicdb/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=edwinkys-oasysdb`](/api/graphcanon/graph?tool=edwinkys-oasysdb) - 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/_
