Filter by your use case:

Limitations

SWE-agent

Cons

SWE-agent is now in maintenance-only mode, with development focused on mini-swe-agent
Requires a language model of choice (e.g., GPT-4o or Claude Sonnet 4) to function

Replit Agent

Cons

Relies on large language models, meaning its behavior is probabilistic and may occasionally make mistakes
Parallel agents (10) require the Pro plan at $100/month; Core does not include them
Advanced features like Extended Thinking and High-Power Models need to be manually activated for complex tasks
