-
9router
Unlimited FREE AI coding. Connect Claude Code, Codex, Cursor, Cline, Copilot, Antigravity to FREE Claude/GPT/Gemini via 40+ providers. Auto-fallback, RTK -40% tokens, never hit limits.

Claude Code learns from your corrections: self-correcting memory that compounds over 50+ sessions. Context engineering, parallel worktrees, agent teams, and 17 battle-tested skills.
Project mention: Stop Rebuilding Your Claude Code Setup - Scaffold It Once with Worclaude | dev.to | 2026-04-16The workflow draws from Boris Cherny's tips (creator of Claude Code at Anthropic), patterns from Affaan Mir's everything-claude-code (Anthropic hackathon winner), Karpathy's coding principles, and community repos like pro-workflow.
-
safari-mcp
Native Safari browser automation for AI agents. 98 tools via AppleScript — zero overhead, keeps logins, runs silently in background. Drop-in alternative to Chrome DevTools MCP with 40-60% less CPU/heat on Apple Silicon.
Project mention: I filed it as a flaky test. It was a crash that try/catch can't reach. | dev.to | 2026-10-04Safari MCP, the open-source server I maintain, runs one process that owns a local bridge port. Any other instance becomes a secondary: it proxies through that primary, and if the primary goes away, it takes the port over. One test covers exactly that handoff. Start a primary, start a secondary, stop the primary, wait for the secondary to say it's listening.
