Where concept artists actually collaborate

Magma (formerly Magma Studio) is a browser-based painting and collaboration canvas aimed at illustrators and game concept teams. Think infinite canvas plus Photoshop-grade brushes plus real-time co-op. It is not trying to be a full Photoshop replacement — it is the best shared space for visual iteration we have tested.

Who it's for: Concept artists, illustrators, art directors, and game studios running remote critique and brainstorming sessions.

Key features

Infinite canvas Spatial boards

Organize references, thumbnails, and finals on one zoomable board.

Real-time co-op Live sessions

Multiple artists paint on the same canvas with cursors and chat.

Pro brushes Painter-grade engine

Custom brushes, layers, and blend modes that feel like desktop software.

Session replay Review process

Replay a drawing session to critique decisions, not just results.

The honest take

✓ What works

  • Best-in-class collaborative painting
  • Runs in browser, no installs
  • Free tier is usable
  • Session replay is great for teaching

✗ What doesn't

  • Not a full Photoshop replacement
  • Performance dips on huge canvases
  • Mobile app is limited
  • Some pro features behind paywall

Verdict

If your work is visual and collaborative, Magma beats sending PSDs back and forth. The $12/mo Pro is a no-brainer for any art team doing remote critique.
