Kiro Web (Preview) is now available at app.kiro.dev for Kiro Pro, Pro+, and Power users. Chat with the agent to explore ideas, fix bugs, and shape changes, or hand off end-to-end tasks that finish as pull requests. Coordinate one change across multiple repos in a single session.

Collaborative and autonomous modes

Work with the agent two ways. In the default collaborative mode, you drive the conversation: discuss approaches, write code together, and ask the agent to open a PR when you're ready. Toggle on Autonomous mode when you want the agent to own the outcome. It asks clarifying questions upfront, builds a plan, delegates to specialized sub-agents, and opens a PR automatically.

GitHub-native workflow

Select the repos you want to work with at the start of a session. The agent clones them into an isolated sandbox and coordinates edits and pull requests across all of them in a single run, from shared libraries to dependent services and clients. Assign work from GitHub issues with the kiro label or a /kiro comment. The agent creates feature branches, commits on your behalf, and opens pull requests with detailed descriptions. Review PRs with comments and the agent picks them up and pushes updates. Use /kiro all to address every reviewer's feedback at once, or /kiro fix to tackle one conversation thread at a time. Learn more ->

Steering that carries forward

Guide the agent with your team's standards and conventions. Steering files in .kiro/steering/ load your patterns at the start of every session, using the same format that works in Kiro IDE and Kiro CLI. You can also teach the agent through PR comments, and your feedback carries forward to future work across all your repositories. Learn more ->

Isolated sandbox by default

Every task runs in its own isolated sandbox. The agent clones your repos, configures the environment from detected project settings, and tears everything down when the task completes. You control network access, environment variables, secrets, and MCP servers from the agent settings page. Learn more ->

The autonomous agent preview is now autonomous mode in Kiro. Start at Kiro Web →

Kiro autonomous agent works independently on development tasks, from implementing features to fixing bugs. It operates asynchronously in isolated sandbox environments, learning from your code reviews and building deep understanding of your codebase and patterns.

Kiro autonomous agent is starting to roll out for individual developers in preview to Kiro Pro, Pro+, and Power subscribers. There's no cost during the preview period, and usage is subject to weekly limits. Teams can join the waitlist to get early access. Learn more ->
