Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Devin
- Pricing not published; specific costs and plan tiers require signup or contact with sales
- Cannot handle extremely difficult tasks reliably; success rate decreases with task complexity
- Requires clear, well-scoped task descriptions; ambiguous requirements reduce effectiveness
- Requires human oversight and integration into existing workflows; not fully autonomous
Zephyr Scale
