What is Dafthunk?
Dafthunk is an open-source visual workflow automation platform that runs entirely in your browser. You build workflows by connecting nodes in a React Flow drag-and-drop editor, and they execute as serverless functions on Cloudflare's global edge network. The platform eliminates the need for infrastructure setup, containers, or server management.
Key features include AI model integration (OpenAI, Anthropic, Google, Cloudflare AI) for text generation, summarization, vision processing, and image generation; browser automation for web scraping, data extraction, screenshot capture, and PDF generation; web scraping tools; data transformation nodes; and API integrations. Workflows can be triggered by HTTP webhooks, queues, cron schedules, or manual initiation. The platform provides persistent storage through Cloudflare D1 (SQL database), R2 (object storage), and KV (key-value store), along with execution logs and workflow state management.
Dafthunk is designed for developers, automation enthusiasts, no-code/low-code users, teams building AI pipelines, web scrapers, and anyone wanting to prototype workflows quickly. It's fully MIT licensed with no enterprise tier, fair-code restrictions, or community edition limitations. The platform launched on Product Hunt in June 2025 and is built on Cloudflare Workers, Hono, and React.
The tool is particularly useful for automating repetitive tasks, creating AI-powered workflows, building data extraction pipelines, generating images from text prompts, text-to-speech conversion, and connecting various APIs without writing traditional code.
