Theo vs — honest comparisons
Six side-by-side comparisons with the tools you might be considering. We don't strawman. Each page tells you when to pick the other instead.
Theo vs Mastra
Mastra is the TypeScript framework for agent orchestration. Theo is the full cycle — coding agent, scaffold, framework, and managed deploy. Same wedge category, different scope.
OpenTheo vs Vercel
Vercel optimizes the frontend layer of AI Cloud. Theo runs the agent itself — coding agent, scaffold, framework, and the backend deploy.
OpenTheo vs Lovable
Lovable generates React previews from a prompt. Theo ships real backends — Postgres, workers, your domain, your code.
OpenTheo vs Cursor
Cursor is the best AI editor in the IDE. TheoCode is the autonomous agent — Plan, Code, Infra modes — that runs the full cycle from idea to deploy.
OpenTheo vs Railway
Railway is the mature general-purpose cloud platform. Theo is the agent-shaped full cycle — coding agent, scaffold, framework, and managed deploy.
OpenTheo vs Claude Code
Claude Code is Anthropic's command-line tool for agentic coding. TheoCode is the Apache-2.0 alternative — Plan/Code/Infra modes, 28 LLM providers, your keys.
