In their own words
Kiro
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.
Replit
Replit is a software creation platform where users can describe applications in natural language and refine them with an AI agent. The agent works through chat, tests and revises code, and can use a browser to produce reports and address issues. Its cloud development environment supports coding and collaboration in a browser, with automatic package installation and built-in authentication, database, hosting, and monitoring. Replit supports websites, mobile projects, designs, slides, animations, data visualizations, 3D, games, documents, and spreadsheets, with more than 100 integrations. The free Starter plan includes daily usage, but limits publishing to one live project and running one background task at a time. Replit Core costs $18 per month billed annually, and Pro costs $90 per month billed annually. Pro supports up to 15 collaborators and 50 viewers, and includes database rollback for up to 28 days. Replit is available on Android, iOS, Linux, macOS, Windows, and web. Its mobile apps support building, sharing, and publishing web apps; native iOS development uses the web version with Expo Go previews.
