Devin 2.0: the AI software engineer coding autonomously
Devin 2.0 is the second iteration of the AI software engineer from Cognition Labs. It runs in a full cloud sandbox with IDE, web browser and terminal, and can deliver complete pull requests to your repos. The drop from $500/mo to $20/mo (plus ACU consumption, Agent Compute Units) made Devin accessible to the mainstream. V2 introduces Devin Wiki, which auto-indexes your repos to surface relevant context, plus Interactive Planning, which makes you validate the plan before execution. For teams looking to delegate full tickets to an AI without babysitting, Devin 2.0 is probably the most polished offer on the market today.
For who
Dev teams wanting to delegate complete tickets (bug fixes, medium features, migrations) to a supervised AI agent without managing local infrastructure.
