AstraCode is an AI-native coding environment built around powerful coding agents. Describe what you want and the agent plans the change across your repository, implements it, runs your tests, and proves them by undoing its change and confirming they fail without it. AstraOne chooses the model and brings in a stronger one when a check fails. The same agent runs in your terminal, CI and pull requests, and inside JetBrains IDEs and Zed. Free to start, no card.
