Dev Tooling (2026)

Developer tooling covers the building blocks for creating AI-powered software: frameworks for writing MCP servers and clients, front-end kits for in-app copilots, environments for running agents, and utilities for testing and operating them. These are the tools you reach for when you are building an agent or AI feature yourself rather than using a finished product.

Look at language and framework fit first (Python, TypeScript, React), then at maturity: documentation quality, release cadence and how breaking changes are handled. For MCP development, a framework that handles transports and authentication saves significant work. For in-app AI, check how the toolkit handles streaming, state and human-in-the-loop steps.
