Node-based canvas wiring together E2B, Daytona, and Cloudflare Browser Rendering in one workflow.

Strengths

•Three sandbox providers in one canvas with per-node Python/Bash execution mode switching
•Variable substitution with {{node_id}} supports raw multiline output between nodes
•One-click Python workflow export lets you deploy pipelines without the UI

Weaknesses

•Zero stars and forks suggests very early stage with no community validation yet
•Orchestrates existing tools without novel architecture — n8n and LangChain do similar

Post Description

The combination of a browser, a LLM and a sandbox seems like the perfect turing machine for the AI agent world - it can probably achieve any task there is to automate.

There can be many ways to play around with this combination but using visual workflow and nodes seemed the most intuitive way, so I am building Sandbox Flow.

Later I am planning on adding local LLMs, a playwright and a local sandbox.

Have a look!
