How It Works
A New Paradigm for Coding with Agents
Give it a task. It shows its plan.
CodeTwin builds a pre-flight impact map before touching any file. See exactly which files get written, which shell commands run, and which functions get affected. You always know what's about to happen before it happens.
Five autonomy levels. You choose when to intervene.
At dependence level 3, it asks when multiple approaches exist. At level 1, it asks before every write. At level 5, it executes and reports. Change the level mid-task. You control how autonomous it gets.
Project memory. Stored locally.
CodeTwin maintains a twin profile per project — stored locally in SQLite, never sent anywhere. It remembers past decisions and why they were made, active constraints, and failure patterns — what broke and in what context.
Works with every major LLM provider.
OpenAI, Anthropic, Groq, Gemini, Mistral, Ollama, Azure. One config field. No vendor lock-in. Bring your own API key and switch providers with a single config change. Zero code changes required.
