pip install browsergymWarning
BrowserGym is meant to provide an open, easy-to-use and extensible framework to accelerate the field of web agent research. It is not meant to be a consumer product. Use with caution!
Tip
π Check out AgentLabβ¨ ! A seamless framework to implement, test, and evaluate your web agents on all BrowserGym benchmarks.

Example of a GPT4-V agent executing openended tasks (top row, chat interactive), as well as WebArena and WorkArena tasks (bottom row).
BrowserGym includes the following benchmarks by default:
- MiniWoB
- WebArena
- VisualWebArena
- WorkArena
- AssistantBench
- WebLINX (static benchmark)
Designing new web benchmarks with BrowserGym is easy, and simply requires to inherit the AbstractBrowserTask class.
To use browsergym, install one of the following packages:
pip install browsergym # (recommended) everything below pip install browsergym-experiments # experiment utilities (agent, loop, benchmarks) + everything below pip install browsergym-core # core functionalities only (no benchmark, just the openended task) pip install browsergym-miniwob # core + miniwob pip install browsergym-webarena # core + webarena pip install browsergym-visualwebarena # core + visualwebarena pip install browsergym-workarena # core + workarena pip install browsergym-assistantbench # core + assistantbench pip install weblinx-browsergym # core + weblinxThen setup playwright by running
playwright install chromiumFinally, each benchmark comes with its own specific setup that requires to follow additional steps.

To install browsergym locally for development, use the following commands:
git clone git@github.com:ServiceNow/BrowserGym.git cd BrowserGym make installContributions are welcome! π
Boilerplate code to run an agent on an interactive, open-ended task:
import gymnasium as gym import browsergym.core # register the openended task as a gym environment # start an openended environment env = gym.make( "browsergym/openended", task_kwargs={"start_url": "https://www.google.com/"}, # starting URL wait_for_user_message=True, # wait for a user message after each agent message sent to the chat ) # run the environment <> agent loop until termination obs, info = env.reset() while True: action = ... # implement your agent here obs, reward, terminated, truncated, info = env.step(action) if terminated or truncated: break # release the environment env.close()MiniWoB
import gymnasium as gym import browsergym.miniwob # register miniwob tasks as gym environments # start a miniwob task env = gym.make("browsergym/miniwob.choose-list") ... # list all the available miniwob tasks env_ids = [id for id in gym.envs.registry.keys() if id.startswith("browsergym/miniwob")] print("\n".join(env_ids))WorkArena
import gymnasium as gym import browsergym.workarena # register workarena tasks as gym environments # start a workarena task env = gym.make("browsergym/workarena.servicenow.order-ipad-pro") ... # list all the available workarena tasks env_ids = [id for id in gym.envs.registry.keys() if id.startswith("browsergym/workarena")] print("\n".join(env_ids))WebArena
import gymnasium as gym import browsergym.webarena # register webarena tasks as gym environments # start a webarena task env = gym.make("browsergym/webarena.310") ... # list all the available webarena tasks env_ids = [id for id in gym.envs.registry.keys() if id.startswith("browsergym/webarena")] print("\n".join(env_ids))VisualWebArena
import gymnasium as gym import browsergym.webarena # register webarena tasks as gym environments # start a visualwebarena task env = gym.make("browsergym/visualwebarena.721") ... # list all the available visualwebarena tasks env_ids = [id for id in gym.envs.registry.keys() if id.startswith("browsergym/visualwebarena")] print("\n".join(env_ids))AssistantBench
import gymnasium as gym import browsergym.workarena # register assistantbench tasks as gym environments # start an assistantbench task env = gym.make("browsergym/assistantbench.validation.3") ... # list all the available assistantbench tasks env_ids = [id for id in gym.envs.registry.keys() if id.startswith("browsergym/workarena")] print("\n".join(env_ids))If you want to experiment with a demo agent in BrowserGym, follow these steps
# conda setup conda env create -f demo_agent/environment.yml conda activate demo_agent # or pip setup pip install -r demo_agent/requirements.txt # then download the browser for playwright playwright install chromiumOur demo agent uses openai as a backend, be sure to set your OPENAI_API_KEY.
Launch the demo agent as follows
# openended (interactive chat mode) python demo_agent/run_demo.py --task_name openended --start_url https://www.google.com # miniwob python demo_agent/run_demo.py --task_name miniwob.click-test # workarena python demo_agent/run_demo.py --task_name workarena.servicenow.order-standard-laptop # webarena python demo_agent/run_demo.py --task_name webarena.4 # visualwebarena python demo_agent/run_demo.py --task_name visualwebarena.398You can customize your experience by changing the model_name to your preferred LLM (it uses gpt-4o-mini by default), adding screenshots for your VLMs with use_screenshot, and much more!
