Kiro (agentic IDE)

As of 2025-11-08.

One‑liner

An agentic IDE from a small team within AWS that structures AI coding around spec‑driven development, steering, agent hooks, and MCP integrations — currently in public preview. Kiro

Overview

  • Spec‑driven development: turn prompts into requirements, designs, and executable tasks; approve changes with live diffs. Kiro
  • Agent hooks & autopilot: background agents can run on events (e.g., on save) to generate tests/docs/optimizations; autopilot executes multi‑step work with user control. Kiro
  • Steering & context: project‑level rules and context (coding standards, workflows) to guide the agent across large codebases. Docs
  • MCP integration: connect to external tools/data (docs, DBs, APIs); supports remote MCP servers and one‑click installs. Remote MCP
  • Models & pricing: default “Auto” agent can mix frontier models; plans are credit‑based (Free, Pro, Pro+, Power). Pricing
  • Built within AWS & security: runs as an AWS application and follows AWS security practices; supervised vs. autopilot modes, trusted commands, etc. Privacy & Security
