| What makes it different | - AI-native environment where agents autonomously plan, implement, test and review their own work across your whole repository
- AstraOne automatically chooses and escalates models based on test results rather than requiring manual model selection
- Code runs on your machine with nothing copied to external servers, enforced privacy at the gateway
- Works in terminal, CI, pull requests and inside JetBrains IDEs and Zed
- Extensions, keybindings and settings carry over from your existing editor
| - Replaces vague prompts with immutable 4-file architectural contracts to prevent AI hallucinations
- Senior Architect interview catches edge cases before coding begins
- Supports both Greenfield and Brownfield project workflows
