- Provider agnostic. Same code works with OpenAI, Anthropic, Google, xAI, Ollama, AWS Bedrock, DeepSeek and more.
- Composable executors. Chain modular executors (prompt + LLM + parser) and swap parts independently.
- Powerful parsers. Parse JSON, lists, regex, markdown etc. with schema validation that throws on mismatch.
- Built-in production features. Automatic retries, timeouts, error handling and hooks for logging/monitoring.
