Astro team launches Flue agent harness
Flue is an open-source, programmable TypeScript framework designed as a model-agnostic and durable agent harness. Created by the Astro team, it features built-in in-memory sandboxing and state recovery to standardize the deployment and management of production AI agents.
The shift from basic prompt wrappers to production-grade agents requires a reliable application harness, and Flue tackles this directly by treating agent orchestration as a developer experience problem.
* Astro's design principles (excellent DX, zero-lock-in, and runtime flexibility) translate beautifully to the AI agent layer.
* In-memory sandboxing using lightweight alternatives to Docker is a clever hack that dramatically speeds up execution for code-related tasks.
* Focus on durable execution addresses one of the most critical failures of agent workflows—the lack of state recovery after mid-process crashes.
