🕵️🌐 Building Browser Agents - notebook
No API? No problem.
Browser Agents can use websites like you do: click, type, wait, read.
📓 Step-by-step notebook: https://colab.research.google.com/github/deepset-ai/haystack-cookbook/blob/main/notebooks/browser_agents.ipynb
🎥 In the video, the Agent:
- Goes to Hugging Face Spaces
- Finds black-forest-labs/FLUX.1-schnell
- Expands a short prompt ("my holiday on Lake Como") into a detailed image generation prompt
- Waits for the image
- Returns the image URL
## What else can it do?
Great for information gathering and summarization
🗞️🗞️ Compare news websites and create a table of shared stories with links
▶️ Find content creator social profiles from YouTube videos
🛍️ Find a product's price range on Amazon
🚂 🚌 Gather public transportation travel options
## How is it built?
🏗️ Haystack → Agent execution logic
🧠 Google Gemini 2.5 Flash → Good and fast LLM with a generous free tier
🛠️ Playwright MCP server → Browser automation tools: navigate, click, type, wait...
Even without vision capabilities, this setup can get quite far.
## Next steps
- Try a local open model
- Move from notebook to real deployment
- Incorporate vision
And you? Have you built something similar? What's in your stack?
