Mastra

mastra.ai/

Mastra is a TypeScript framework for building AI agents, bundling agents, workflows, memory, a server, and observability into one open-source toolkit that works with React, Next.js, or Node. The homepage displays its GitHub star count (28.3k) directly in the hero rather than in a footer badge, and backs its docs with two self-published books it says have been distributed 240K+ and 100K+ copies respectively, plus a weekly podcast. It shows customer logos like Salesforce, MongoDB, and WorkOS alongside linked case studies, and includes a live-looking dashboard mockup of agent traces, metrics, and evals rather than a static feature screenshot.
