# AI agent frameworks compared

> Chloe, OpenClaw, Mastra, eve, Google's ADK, LangChain.js, the OpenAI Agents SDK and the Claude Agent SDK side by side: written in code, schedules, cost, a dashboard, memory you can read, and who keeps the data.

Each cell is a mark and a few words. Yes is built in, free and on your own machine; partly is tokens without dollars, a hosted or paid service, or code you would write yourself. Every cell about another project was read from its own docs on 7 Oct 2026.

- **Written in code**: The agent is a program you can read, test and keep in git.
- **Mix code, AI and agents**: Plain code, one typed answer from an AI, and an agent with tools, in one job, in the order your code says.
- **Any model**: Any AI provider with one key, or a subscription you already pay for, and a model per job.
- **Runs on a schedule**: Every morning at 8, or every 15 minutes, with nothing else to set up.
- **Shows the price**: What each run cost you, in dollars, with no other service to sign up for.
- **Comes with a dashboard**: A page to watch every run: what it did, and what it cost.
- **Memory you can read**: What it remembers is Markdown files you can open, change, or read in a dashboard.
- **Yours to keep**: Open source, on your own machine, and the runs and memory stay there.
