Future AGI
Open-source platform for evaluating, tracing and improving AI agents.
Future AGI builds an open-source, self-hostable platform for shipping AI agents that covers the lifecycle in one feedback loop: simulations of edge cases before launch, evaluations, tracing and observability in production, real-time guardrails, an LLM gateway, datasets and optimization. It positions itself as a replacement for stitching together separate tools for evals, observability, guardrails and simulation. The platform is Apache 2.0 licensed, with a free cloud tier alongside self-hosting.

Serverless cloud built for AI and agentic compute.
Modal lets teams run inference, fine-tuning and arbitrary agent workloads as serverless Python without managing infrastructure — a common substrate for harness backends at scale.

Durable execution for long-running agent workflows.
Temporal's durable execution engine is widely adopted to make agent pipelines reliable: state survives crashes, retries are automatic, and workflows run for minutes or months. A key piece of serious harness infrastructure.
