Core features.

Feature cards focus on what the tool helps users do, not generated setup commands.

01

Mastra is a framework for building AI-powered applications and agents with a modern TypeScript stack.

02

Model routing - Connect to 40+ providers through one standard interface.

03

Use models from OpenAI, Anthropic, Gemini, and more.

04

Agents - Build autonomous agents that use LLMs and tools to solve open-ended tasks.

05

Agents reason about goals, decide which tools to use, and iterate internally until the model emits a final answer or an optional stopping condition is met.

06

Workflows - When you need explicit control over execution, use Mastra's graph-based workflow engine to orchestrate complex multi-step processes.

07

Mastra workflows use an intuitive syntax for control flow (.then(), .branch(), .parallel()).

08

Human-in-the-loop - Suspend an agent or workflow and await user input or approval before resuming.

04

Agent / Skill / MCP / Workflow fit.

This panel keeps technical format separate from the user-facing AI category.
