You require integration with specific proprietary tools or frameworks not supported by Haystack. Your development team is not familiar with Python-based technologies, since Haystack primarily supports Python-based workflows. You are looking for a completely managed service rather than an open-source framework that requires more hands-on configuration and customization. ### Is airweave or haystack more popular on GitHub? haystack has more GitHub stars (26,073 vs 6,558). Stars measure visibility, not whether either tool fits your constraints. ### Are airweave and haystack open source? Yes - both are open-source projects on GitHub (airweave: MIT, haystack: Apache-2.0). ### Where can I find alternatives to airweave or haystack? GraphCanon lists graph-backed alternatives at [airweave alternatives](/tools/airweave-ai-airweave/alternatives) and [haystack alternatives](/tools/deepset-ai-haystack/alternatives) ([airweave markdown twin](/tools/airweave-ai-airweave/alternatives.md), [haystack markdown twin](/tools/deepset-ai-haystack/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/airweave-ai-airweave-vs-deepset-ai-haystack.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, airweave or haystack? airweave: Steady. haystack: 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 airweave and haystack? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [airweave trust report](/tools/airweave-ai-airweave/trust); [haystack trust report](/tools/deepset-ai-haystack/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=airweave-ai-airweave`](/api/graphcanon/graph?tool=airweave-ai-airweave) - 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/_
