Developer Builds Browser Sandbox Prototype For LLM Agents
|
6.8
A developer built Co-do, a browser-based demo testing whether web sandboxing can safely run agentic LLM tasks such as Anthropic's Claude Cowork. The post examines filesystem access (File System Access API), network controls via Content Security Policy, and iframe sandboxing, and notes trade-offs around read/write permissions and exfiltration risks. The analysis assesses feasibility and practical constraints for browser-hosted automation.
