| MadAppGang/magusMIT-licensed Claude Code plugin marketplace and companion plugin suite for software development, combining commands, agents, skills, hooks, MCP runtimes, terminal control, semantic code navigation, multi-model orchestration, project provisioning, UI review, and stack-specific guidance; several features require external binaries, provider credentials, or dependent plugins. | Claude Code plugin marketplace and development workflow suite | Mixed: core plugin packaging and documentation appear usable, while readiness varies substantially by plugin and external dependency. | Sep 19, 2026 |
| calcom/cal.diyMIT-licensed, community-maintained self-hosted scheduling platform forked from Cal.com with commercial and enterprise code removed; it includes a Next.js web app, NestJS API v2, PostgreSQL/Prisma data layer, booking embeds, calendar and conferencing integrations, Docker deployment materials, and repository-local spec and engineering-rule documents intended to guide Claude during development, but no distributable Claude Code plugin, skill, hook, MCP server, or command is evidenced. | Self-hosted scheduling application with repository-local Claude development context | Usable for advanced self-hosters and contributors; explicitly not recommended by its README for production or commercial deployment. | Sep 18, 2026 |
| AbdelftahZowail/QuicklyMIT-licensed, self-hosted cold-email application with campaign sequencing, inbox rotation, reply processing, analytics, REST APIs, webhooks, an n8n community node, and a remote MCP server that exposes lead-related tools; it can serve Claude Code only as a separately deployed MCP tool surface by inference, because supplied files document Cursor and generic MCP clients but no Claude Code-specific setup. | Self-hosted cold-email platform with remote MCP tools | Self-hostable with substantial production configuration | Sep 18, 2026 |
| chatwoot/chatwootChatwoot is a self-hostable omnichannel customer-support platform with shared inboxes, customer records, help-center publishing, reporting, automations, integrations, and an enterprise Captain support agent; supplied evidence shows no Claude Code extension, bridge, or compatibility path. | Omnichannel customer-support platform | Production-oriented but operationally substantial; only the latest version receives security support, and supplied files do not establish Claude Code compatibility. | Sep 18, 2026 |
| mautic/mauticEstablished PHP-based, self-hostable marketing automation application for integrated, multi-channel campaigns, segmentation, customization, and user-controlled data; it is a standalone platform with no supplied evidence of a Claude Code extension, skill, hook, MCP server, or other native Claude integration. | Self-hosted marketing automation application | Production use is directed to tagged, Composer-installed, or prepackaged releases; source outside tagged releases is not production-ready. | Sep 18, 2026 |
| n8n-io/n8nSource-available workflow automation and AI-agent platform with a visual editor, custom JavaScript and Python, self-hosted or cloud deployment, extensive integrations, a public API CLI, and a repository-local Claude Code plugin used by n8n contributors; for external Claude Code users, the documented @n8n/cli can install an Agent Skill that teaches Claude to manage an n8n instance. | Workflow automation and AI-agent platform | Production-oriented, with deployment and enterprise features documented; Claude integration evidence is split between a contributor plugin and a user-facing CLI skill. | Sep 17, 2026 |
