Type what you want in natural language. Crab-Agent navigates pages, clicks elements, fills forms, reads content, manages tabs, records workflows — all autonomously. Bring your own API key. Works with any LLM provider.
A complete agent toolkit built into a Chrome side panel. No coding required.
Takes screenshots and reads the full DOM tree with interactive element references. Sees your page like a human would.
Click, type, scroll, drag, navigate, open tabs, fill forms, upload files, execute JavaScript — all via Chrome DevTools Protocol.
Remembers your preferences, rules, and personal info across sessions. Dream consolidation keeps memory clean and relevant.
Record browser interactions as reusable workflows. Replay them on demand or let the agent invoke them automatically.
Schedule tasks for the future — one-time or recurring with cron expressions. The agent runs them automatically via Chrome alarms.
You stay in control. Choose between Ask, Auto, or Strict modes. Sensitive pages always require explicit approval.
A tool-use agent loop that keeps going until the task is done.
Open the side panel and type what you want in plain language. Attach screenshots if needed. "Book the cheapest flight to Tokyo for next Friday"
Crab-Agent takes a screenshot and reads the DOM, building a map of every interactive element with coordinate references.
The conversation (including the visual context) is sent to your chosen LLM. It selects a tool — click, type, navigate, read — and the extension executes it via CDP.
The result is appended to the conversation and the loop continues. The agent handles multi-step flows, tab switching, form filling, and error recovery automatically.
The agent picks the right tool for each step. Here's what's in the toolkit.
Chrome MV3 service worker, React side panel, multi-provider LLM gateway.
Free to use. Bring your own API key and let Clawd handle the rest.
Crab-Agent wouldn't exist without these amazing projects and their creators.
The adorable "Clawd" crab pixel-art mascot and SVG animations used throughout Crab-Agent are derived from the Clawd Tank project by Marcio Granzotto. Thank you for the amazing crab character!
Core agent loop architecture and browser automation logic inspired by Anthropic's computer-use approach. The tool-use cycle pattern — screenshot, observe, decide, act — draws heavily from their pioneering work on AI browser agents.
