Mastra
An open-source framework for building AI workflows and agents, supporting the orchestration of multi-model invocations and tool integrations.
Timeline (last 90 days)
A survey of 12 mainstream Agent frameworks found that none of the frameworks provides monetary-denominated tool-call budget control in its documentation (C5 is all no).
Pexafy's official documentation lists tested configurations for the OpenAI Agents SDK, Claude Agent SDK, Google ADK, CrewAI, LlamaIndex, Mastra and Strands Agents.
In one Mastra configuration, storing messages as a Postgres jsonb column caused property key order to change on read, thereby changing the prompt bytes and breaking the cache.
Pink Agentic AI Payments conducted a systematic review of the 12 most popular Agent frameworks and concluded that none of the frameworks documents a currency-denominated tool-call budget control (C5).
Outside's technical stack is: Expo/React Native for audio recording, an Express backend on Render, ElevenLabs Scribe for transcription, a Mastra workflow invoking the Gemma model, and ElevenLabs TTS for speech synthesis.
Agent framework selection is fundamentally an engineering constraints problem: choose MAF for the Microsoft stack, Google ADK for GCP, Mastra for TS teams, LlamaIndex for data processing, CrewAI for role mapping, OpenAI Agents SDK for minimalist low-level needs, and LangChain for cross-model compatibility.
Mastra is tailored for TypeScript teams with out-of-the-box frontend connectors, but under non-default memory settings, increased conversation volume triggers model compression, causing API costs to rise.
Brain is a minimalist Agent platform positioned as a lightweight alternative to LangChain and Mastra.
Mastra is a TypeScript-first AI Agent framework created by one of the co-founders of Gatsby.js.
