Spec score 8.2 #11 of 21 in Agentic Ides

What it is

Kiro is an agentic development environment for professional developers, software teams, businesses, and enterprises. Its spec-driven workflow turns prompts into requirements, designs, and tasks for agents to implement. Deterministic tools, including property-based tests, verify code correctness and its alignment with user intent. Background agent hooks can update documentation, generate unit tests, or optimise performance, while steering files let users supply project or global context, standards, and workflows. The IDE supports VS Code settings, themes, Open VSX plugins, and MCP servers for connecting agents to external services, APIs, documentation, and tools. Desktop versions run on macOS, Windows, and Linux; Kiro also has a web interface and mobile app for accessing cloud sessions from a phone. Kiro Web requires a paid subscription. The free plan includes 50 credits per month; KIRO PRO costs $20 a month billed per user and includes 1,000 credits. Kiro says it encrypts data in transit and at rest; enterprise administrators can configure customer-managed keys.
