A spec-driven AI IDE and agent platform that plans, builds, reviews, and verifies real engineering work.
You describe intent and context first; Kiro captures requirements and design as specifications, then verifies the finished implementation against them.
Kiro Crew watches your backlog, codebase, or CI, triages new work, delegates to specialized bots, and returns results for your review.
Long tasks split into checked steps so agents cannot shortcut a failed test, and review agents inspect diffs before a human approves a merge.
Use the IDE, mobile, or web, run headless in CI/CD with the CLI, or trigger Kiro from Slack, Microsoft Teams, GitHub, and GitLab.
Run many coding agents in parallel, each in its own worktree
Each agent gets its own isolated Git worktree, so multiple agents can edit, test and build concurrently without conflicts.
Works with Claude Code, Codex, Gemini, Cursor CLI, OpenCode, Copilot, Cline and many other command-line agents using subscriptions you already have.
A built-in browser lets you click any element to copy its HTML, styles and selector, or screenshot a page and drop that context straight into an agent prompt.
Review AI output, run commands and arrange terminals, browsers, files and diffs in panes shaped to the task at hand.
