Foundry Blog: Reproducible Web Environments for Agent Evaluation

Foundry provides a deterministic web simulator and an annotation framework designed for building and evaluating browser-based agents. The platform focuses on reproducible testing, high-quality labeling, and scalable evaluation to help you benchmark, debug, and continuously improve agent performance without the unpredictability of live web environments.

What It Is

Foundry offers a deterministic web simulation environment paired with an annotation framework. This combination enables researchers and developers to collect ground-truth labels, run fair agent evaluations, and debug performance in a controlled setting. By removing issues like web drift, IP bans, and rate limits, Foundry aims to streamline the development lifecycle for browser agents.

How It Works

1. Deterministic Web Simulation: Reproduce identical web sessions and scenarios to ensure consistent evaluation across experiments.
2. Annotation Framework: Collect high-quality labels and ground-truth data necessary for training and evaluation.
3. Agent Evaluation: Benchmark agents against reproducible tasks and environments to quantify performance with confidence.
4. Debug & Improve: Use the deterministic setup to identify failure modes and iterate on agent strategies.

This setup eliminates variability introduced by the live web, enabling fair comparisons and reliable progress tracking.
