COMPARE

Antimatter vs. Cursor

Cursor is a powerful AI-native IDE. Antimatter is an operations platform — orchestration, project boards, and team channels ship alongside the editor so agents can run the whole workflow, not just suggest the next line.

Comparison reflects publicly available product capabilities as of July 2026.

CHANNELS

One team chat for humans and agents

Channels keeps your whole team in one ongoing conversation — human teammates and AI agents side by side. No separate collaboration subscription: status updates, decisions, and @mentions all happen in the same thread across every project.

  • One continuous workspace for channels, DMs, and agent threads
  • Humans and agents collaborate in real time — no handoffs between tools
  • Voice notes, attachments, and reactions keep the conversation moving

BOARDS

Your project board, built into every workspace

Every workspace ships with a kanban board that agents read and write as their orchestration source of truth — no separate project-management tool required. They pick up tasks, check off acceptance criteria, and move cards while you watch; you only step in for approvals and blockers.

  • Agents move cards in real time with full activity threads
  • Rich tasks: acceptance criteria, links, attachments, epics
  • Blockers deep-link to the exact setting that fixes them
CUSTOMIZE

Plugins, MCPs, and skills you already use

Wire up the same integrations, MCP servers, and reusable skills your team already runs. Toggle plugins for repos and deploys, connect tool servers for APIs and design files, and teach agents repeatable workflows — all from one place.

  • Plugin marketplace for GitHub, Vercel, Stripe, Supabase, and more
  • Custom MCP servers with tool discovery and authentication flows
  • Reusable skills agents can invoke across every project

Add your OpenRouter key

One key unlocks every model. Test the connection and intelligent routing takes it from there.

Every request is routed to the right model for the job — frontier models only when the task demands it, efficient models for everything else. On a typical 30-day workload that's up to 90% saved versus routing everything to a frontier model.

FAQ

Questions, answered

Setup, routing, agents, billing — the details teams ask before they ship.

For live inference, yes — paste your key in Settings → Models & Routing and orchestrator conversations run real models immediately. Without a key the platform runs in a fully scripted demo mode so you can explore everything first. Your key never leaves your browser.
