Avoid TMA1 if you prefer cloud-based solutions or require real-time collaboration features that it does not inherently support due to its self-hosted nature. Do not use TMA1 in environments sensitive to open ports, since it runs a local server and dashboard accessible at default localhost settings which may not suit all security policies. ### When should I avoid agentcanvas? If your AI agents are not built using Pydantic or do not utilize Logfire for tracing, as agentcanvas specifically works with these technologies. When the level of detail provided in the HTML diagrams is unnecessary or when you lack access to the required Logfire traces and associated tokens. ### Is tma1 or agentcanvas more popular on GitHub? tma1 has more GitHub stars (117 vs 82). Stars measure visibility, not whether either tool fits your constraints. ### Are tma1 and agentcanvas open source? Yes - both are open-source projects on GitHub (tma1: Apache-2.0, agentcanvas: MIT). ### Where can I find alternatives to tma1 or agentcanvas? GraphCanon lists graph-backed alternatives at [tma1 alternatives](/tools/tma1-ai-tma1/alternatives) and [agentcanvas alternatives](/tools/vstorm-co-agentcanvas/alternatives) ([tma1 markdown twin](/tools/tma1-ai-tma1/alternatives.md), [agentcanvas markdown twin](/tools/vstorm-co-agentcanvas/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/tma1-ai-tma1-vs-vstorm-co-agentcanvas.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, tma1 or agentcanvas? tma1: Very active. agentcanvas: 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 tma1 and agentcanvas? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [tma1 trust report](/tools/tma1-ai-tma1/trust); [agentcanvas trust report](/tools/vstorm-co-agentcanvas/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=tma1-ai-tma1`](/api/graphcanon/graph?tool=tma1-ai-tma1) - 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/_
