CogSend

OpenSend is a self-hosted transactional and marketing email platform built on Amazon SES for sending transactional mail, newsletters, and campaigns. It provides a dashboard, a TypeScript SDK distributed as the `opensend-js` npm package, and an MCP server over one public API; the video also describes send simulation and delivery-status logs. The project supports Docker or Cloudflare deployment, uses Google-only sign-in, keeps API-secret setup out of the browser, and recommends starting with simulated sending before provisioning infrastructure or sending real email.

Simple Commenter is a website-feedback platform with an MCP server that connects client comments, captured page and element context, developer briefs, and design assets to AI tools. Its hosted MCP endpoint supports OAuth connections to ChatGPT, Claude, and Codex, with access restricted to selected companies, projects, and actions. Cursor and Claude Code can use a local npm-based server configured through `@simple-commenter/mcp-server`; the setup provides commands for initialization, serving, and diagnostics. AI coding tools can investigate open feedback, propose code changes, post replies, and update comment status, while users review and test the resulting changes.

loomfeed is a self-hosted, open-source Reddit alternative for AI agents and humans, developed as a community platform with communities, posts, threaded comments, voting, and agent debates. AI agents have identities, API keys, trust scores, and reputations, and can publish, reply, and vote through REST, MCP, or the A2A protocol. The platform records provenance for agent-generated content, including sources, confidence scores, model information, and generation methods. A typed citation graph relates claims as supporting, contradicting, extending, or quoting one another. Epistemic status labels such as Hypothesis, Supported, Contested, Refuted, and Consensus, along with source checking and research-depth scoring, are used to assess content; only human participants can grant an agent post the Human Seal of Approval. It also provides structured head-to-head agent debates and falsifiable predictions with resolve-by times and Brier-scored accuracy records. The repository is MIT-licensed and supports self-hosting with Docker Compose. Its documented stack includes a Go backend, Next.js frontend, PostgreSQL with pgvector, Redis, an API, an MCP gateway, and a web frontend; optional LLM providers, OAuth, analytics, and email services remain disabled until configured.

Nodyx is an AGPL-3.0 self-hosted community platform that combines forums, real-time chat, voice rooms, a collaborative canvas, a public homepage builder, and streamer-oriented features in one server. It provides searchable posts, moderation tools, widgets, and community-owned hosting. Its real-time layer uses WebRTC peer-to-peer voice and a Socket.IO fallback. The project includes a Rust STUN/TURN voice relay and a Rust TCP tunneling relay for publishing home servers without inbound ports. The documented stack includes a TypeScript and Fastify backend, a SvelteKit frontend with the TipTap editor, PostgreSQL for data and full-text search, and Redis for sessions and presence.

CrawlSEO is an open-source, self-hosted SEO monitoring dashboard for founders. It combines Google Search Console analytics for keywords, pages, clicks, impressions, click-through rate, and position changes with 28-day comparisons; a concurrent site crawler that handles up to 2,000 pages, assigns a health score, identifies 16 issue types, scores content, and provides per-page audit and remediation data; Core Web Vitals monitoring through PageSpeed Insights; historical rank tracking; SEO opportunity detection; alerts; and CSV export. Optional keyword research and backlink analysis use DataForSEO with a bring-your-own-key setup, while Google Autocomplete provides a free fallback for keyword suggestions. The included Model Context Protocol server exposes 10 tools for Claude Code, Claude Desktop, and Cursor. Connected AI agents can query SEO data, run crawls, inspect crawl issues and performance, and find opportunities. The application is built with Next.js, TypeScript, PostgreSQL, Prisma, and NextAuth.js, and is distributed under the MIT license for local or Docker Compose deployment with Google OAuth and a database. It is described as free and open source, with self-hosting intended to keep site data under the operator's control.
