Show HN: Grov – Multiplayer for AI coding agents

Summary

grov Collective AI memory for engineering teams. When one dev's AI figures something out, every dev's AI knows it. Website • Dashboard • Quick Start • Features • Contributing The Problem Your team's AI agents are learning in silos. Dev A's Claude spends 10 minutes understanding your auth system Dev B's Claude does the exact same exploration the next day Dev C asks a question that was already answered last week Every new session starts from zero The waste: Redundant exploration, duplicate token spend, knowledge that disappears when sessions end. The Solution Grov captures what your team's AI learns and shares it automatically. Dev A: "How does auth work in this codebase?" ↓ Claude investigates, figures it out ↓ Grov captures the reasoning + decisions ↓ Syncs to team dashboard ↓ Dev B: "Should we add password salting?" ↓ Claude already knows: "Based on verified team knowledge, no - this codebase uses OAuth-only, no passwords stored" ↓ No exploration needed. Instant expert answer. Measured impact: Tasks drop from 10+ minutes to 1-2 minutes when team context is available. Quick Start npm install -g grov # Install grov init # Configure (one-time) grov proxy # Start (keep running) Then use Claude Code normally in another terminal. That's it. Other Tools grov setup # Interactive setup (Cursor, Zed, Codex) grov init cursor # Direct setup for Cursor CLI grov init antigravity # Direct setup for Antigravity IDE integrations (Cursor, Zed, Antigravity) use native MCP - no proxy needed. Important: Your ANTHROPIC_API_KEY must be set permanently in your shell profile, not just with export in a terminal. See Troubleshooting for setup instructions. For team sync: grov login # Authenticate via GitHub grov sync --enable --team ID # Enable sync for your team Free for individuals and teams up to 3 developers. What Gets Captured Real reasoning, not just file lists: Architectural decisions, patterns, and rationale - automatically extracted and synced to your team. Every captured memory inc...
