Codegen vs OpenCode
Open source AI coding agent that works in your terminal, IDE, or desktop app, supporting 75+ LLM providers with no code storage. Here is how OpenCode ($0/mo open source) stacks up against Codegen ($15/mo) across cost, hosting, data privacy, and real-world trade-offs.
OpenCode is a verified MIT-licensed open-source replacement for Codegen. Switching from Codegen ($15/mo) saves $180/yr per solo seat, or $900/yr for a 5-person team. Deployment: Runs on Local.
The catch: It gives you one agent with tools rather than an orchestrator that splits a task across research, coding, browser and review workers.
