Guided scenario
Open-source AI agent frameworks
Building AI agents that call tools, hand off work, and run for minutes or hours takes more than a prompt and an API key. This shortlist ranks agent frameworks and builders by open-source licensing and self-hosting first, then multi-agent support and durable execution that survives failures mid-run. Also weigh whether your team prefers code or a visual builder, and how hosted plans price runs and seats.
