[SPIN](https://uclaml.github.io/SPIN/) reports 1.2k GitHub stars, 105 forks, and 24 open issues, last pushed May 8, 2024. [agents](https://sethhobson.com) has 38k stars, 4.0k forks, and 1 open issues, last pushed Jul 8, 2026. Figures are from public GitHub metadata via [SPIN's repository](https://github.com/uclaml/SPIN) and [agents's repository](https://github.com/wshobson/agents). | | [SPIN](/tools/uclaml-spin.md) | [agents](/tools/wshobson-agents.md) | | --- | --- | --- | | Tagline | The official implementation of Self-Play Fine-Tuning (SPIN) | Multi-harness agentic plugin marketplace for various AI agents | | Stars | 1,247 | 37,779 | | Forks | 105 | 4,050 | | Open issues | 24 | 1 | | Language | Python | Python | | Adopt for | - | The agents tool is a marketplace for plugins that enhances multiple AI agents, offering integration and management capabilities across several platforms, including Claude Code, Codex CLI, Cursor, OpenCode, GitHub Copilot | | Persona | - | - | | Runtime | - | - | | License | Apache-2.0 | MIT | | Categories | Developer Tools | AI Agents, Developer Tools | ## Trust and health _Sourced signals - not a safety guarantee.

Validate activity before betting a new project on SPIN. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ## When NOT to use agents - You are working solely within a niche environment that isn't one of the supported platforms (like Claude Code, Codex CLI, etc.) because it may not offer compatible plugins or extensive support - Your project requirements do not include interoperability between multiple AI agents and you only need to leverage functionalities from a single AI agent with a robust in-built plugin ecosystem ## Common questions ### What is the difference between SPIN and agents? SPIN: The official implementation of Self-Play Fine-Tuning (SPIN). agents: Multi-harness agentic plugin marketplace for various AI agents. See the comparison table for live GitHub stats and shared categories. ### When should I choose SPIN over agents? Choose SPIN over agents when License: SPIN is Apache-2.0, agents is MIT; Tags unique to SPIN: deep-learning, fine-tuning, large-language-models, python. ### When should I choose agents over SPIN? Choose agents over SPIN when License: agents is MIT, SPIN is Apache-2.0; Tags unique to agents: agent-skills, agentic-ai, automation, prompt-engineering; Also covers AI Agents; You are working specifically within the ecosystems of Claude Code, Codex CLI, Cursor, OpenCode, GitHub Copilot, or Gemini CLI, as it provides tailored plugins for these environments. ### When should I avoid SPIN? Last GitHub push was 795 days ago (dormant maintenance, May 8, 2024). Validate activity before betting a new project on SPIN. Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ### When should I avoid agents? You are working solely within a niche environment that isn't one of the supported platforms (like Claude Code, Codex CLI, etc.) because it may not offer compatible plugins or extensive support Your project requirements do not include interoperability between multiple AI agents and you only need to leverage functionalities from a single AI agent with a robust in-built plugin ecosystem ### Is SPIN or agents more popular on GitHub? agents has more GitHub stars (37,779 vs 1,247). Stars measure visibility, not whether either tool fits your constraints. ### Are SPIN and agents open source? Yes - both are open-source projects on GitHub (SPIN: Apache-2.0, agents: MIT). ### Where can I find alternatives to SPIN or agents? GraphCanon lists graph-backed alternatives at [SPIN alternatives](/tools/uclaml-spin/alternatives) and [agents alternatives](/tools/wshobson-agents/alternatives) ([SPIN markdown twin](/tools/uclaml-spin/alternatives.md), [agents markdown twin](/tools/wshobson-agents/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/uclaml-spin-vs-wshobson-agents.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, SPIN or agents? SPIN: Dormant. agents: 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 SPIN and agents? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [SPIN trust report](/tools/uclaml-spin/trust); [agents trust report](/tools/wshobson-agents/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=uclaml-spin`](/api/graphcanon/graph?tool=uclaml-spin) - 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/_
