Mastra
the most complete typescript-native agent framework
the batteries-included choice for typescript: workflows with suspend/resume, memory, evals and a dev playground, with excellent dx. younger and smaller than the python leaders.
mastra, from the gatsby team, is a typescript-native framework bundling agents, deterministic workflows (with suspend/resume for human-in-the-loop), memory, rag, evals, tracing and mcp, with a local dev playground and serverless/edge deploy. among typescript-first options it's the most complete, and its dx is a genuine strength. it's cross-provider, built on the vercel ai sdk's provider layer.
it's younger and has a smaller ecosystem than the python leaders, and its durable execution is workflow-based rather than temporal-grade. the licence is apache-2.0 for the core with a separately-licensed commercial ee/ directory — github mislabels it, but the file is clear — which matters to some buyers.
the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
