WebArena-Verified

WebArena-Verified is the verified release of the WebArena benchmark. It distributes a curated, version-controlled dataset of web tasks together with deterministic evaluators that operate on agent responses and captured network traces. The project is designed for reproducible benchmarking of web agents and provides tooling for both single-task debugging and batch evaluation.

🎯 Highlights

• Fully audited benchmark: Every task, reference answer, and evaluator has been manually reviewed and corrected
• Offline evaluation: Evaluate agent runs without requiring live web environments using network trace replay
• Deterministic scoring: Removed LLM-as-a-judge evaluation and substring matching in favor of type-aware normalization and structural comparison
• WebArena-Verified Hard subset: A difficulty-prioritized 258-task subset for cost-effective evaluation

🌐 Environments

Note: We have fixed multiple known issues in several environments. See the Environments documentation for details on fixes and current behavior.

Start and Stop Sites

Run sites with the built-in CLI, or run site containers directly with Docker.

# CLI
webarena-verified env start --site <site>  # sites: shopping, shopping_admin, reddit, gitlab, wikipedia, map
webarena-verified env setup init --site wikipedia --data-dir ./downloads  # data download required
webarena-verified env start --site wikipedia --data-dir ./downloads
webarena-verified env setup init --site map --data-dir ./downloads  # data download required
webarena-verified env start --site map
webarena-verified env stop --site <site>
webarena-verified env stop-all

# Docker
docker run -d --name webarena-verified-shopping -p 7770:80 -p 7771:8877 am1n3e/webarena-verified-shopping
docker run -d --name webarena-verified-shopping_admin -p 7780:80 -p 7781:8877 am1n3e/webarena-verified-shopping_admin
docker run -d --name webarena-verified-reddit -p 9999:80 -p 9998:8877 am1n3e/webarena-verified-reddit
docker run -d --name webarena-verified-gitlab -p 8023:8023 -p 8024:8877 am1n3e/webarena-verified-gitlab

  am1n3e/webarena-verified-wikipedia

# Map: run setup first (webarena-verified env setup init --site map --data-dir ./downloads)
docker run -d --name webarena-verified-map \
  -p 3030:3000 -p 3031:8877 \

Environment Control

Check status and initialize environments via env-ctrl using CLI or HTTP API.

# CLI (inside a running site container)
docker exec <container> env-ctrl status
docker exec <container> env-ctrl init

# HTTP
curl http://localhost:8877/status
curl -X POST http://localhost:8877/init

See the Environments documentation and Environment Control docs for site-specific Docker commands, ports, and credentials.

🧪 Evaluate A Task

Evaluate a task using the CLI or programmatically:

CLI:

webarena-verified eval-tasks \
  --task-ids 108 \
  --output-dir examples/agent_logs/demo \
  --config examples/configs/config.example.json

Library:

Start by creating a WebArenaVerified instance with your environment configuration:

from pathlib import Path
from webarena_verified.api import WebArenaVerified
from webarena_verified.types.config import WebArenaVerifiedConfig

# Initialize with configuration
config = WebArenaVerifiedConfig(
    environments={
        "__GITLAB__": {
            "urls": ["http://localhost:8012"],
            "credentials": {"username": "root", "password": "demopass"}
        }
    }
)
wa = WebArenaVerified(config=config)

# Get a single task
task = wa.get_task(44)
print(f"Task intent: {task.intent}")

Once you have your agent's output, evaluate it against the task definition:

With Files:

# Evaluate a task with file paths
result = wa.evaluate_task(
    task_id=44,
    agent_response=Path("output/44/agent_response_44.json"),
    network_trace=Path("output/44/network_44.har")
)

print(f"Score: {result.score}, Status: {result.status}")

With Inline Response:

# Evaluate a task with inline response
result = wa.evaluate_task(
    task_id=44,
    agent_response={
        "task_type": "NAVIGATE",
        "status": "SUCCESS",
        "retrieved_data": None
    },
    network_trace=Path("output/44/network_44.har")
)

print(f"Score: {result.score}, Status: {result.status}")

See the Quick Start Guide for a complete walkthrough using example task logs.
