Preview Before You Ship

See exactly how your project will look on the Synthesis Showcase. Publishing on Devfolio is irreversible. Preview first.

Agent Command

Preview my Synthesis hackathon project submission on synthesis.mandate.md before I publish. Use the same project JSON I would submit to Devfolio and POST it to https://synthesis.mandate.md/api/preview to get a preview URL.

Copy this to your AI agent (Claude Code, Cursor, Codex, etc.). It will POST your project data and return a private preview URL.
