Speed comparison

Task: Create issue, assign to teammate, link GitHub PR, set priority (timed test)

Tool	Keyboard only	Mixed (keyboard + mouse)
Linear	8 seconds	12 seconds
Height	12 seconds	16 seconds
Plane	18 seconds	22 seconds

Winner: Linear significantly faster for keyboard-heavy workflows.

AI features deep-dive

Linear

AI triage: Suggests priority based on content (e.g., "payment failing" → High priority)
Auto-labeling: Applies labels based on keywords
Limited compared to Height

Height

Auto-assignment: "AI bug in checkout" → assigns to AI engineer who owns checkout
Smart lists: "Show tasks blocked on external API" (AI understands context)
Task extraction: Paste meeting notes, AI creates structured tasks
Auto-tagging: Analyzes issue content, suggests relevant tags
Smart notifications: AI determines which updates you care about

Plane

No AI features currently.

Winner: Height by far -most comprehensive AI automation.

GitHub integration

Linear:

Commit: "LIN-123 Fix embeddings query"
→ Auto-links to Linear issue
→ Updates issue status to "In Progress"
→ Creates branch suggestion: "max/lin-123-fix-embeddings-query"

Height:

PR merged → Updates task to "Done"
Basic integration, less seamless than Linear

Plane: Similar to Height -functional but not as polished.

Winner: Linear for developers shipping multiple PRs/day.

Real-world usage

At Athenic, we tested all three:

Linear (30 days):

✅ Team loved speed and GitHub integration
✅ Keyboard shortcuts saved ~10 min/day per developer
❌ Missed AI features for auto-assignment
❌ Expensive beyond 10 users

Height (30 days):

✅ AI auto-assignment worked well (70% accuracy)
✅ Spreadsheet view great for sprint planning
❌ Slower interface frustrating for developers
✅ Cost-effective

Plane (30 days):

✅ Self-hosted option appealing for compliance
❌ Missing AI features deal-breaker
❌ Setup overhead (Docker, monitoring)
✅ No vendor lock-in

Final choice: Linear (team <10, free tier + speed worth it)

Expert quote (Karri Saarinen, CEO of Linear): "We optimize for speed because engineers context-switch constantly. Every 200ms delay compounds when you're managing 50 issues/day."
