Polar
Polar is basically DumDumDeploy for Sui. You sign in with GitHub, pick a repo, and Polar builds it and publishes it as a Walrus Site, without you ever touching a Sui wallet or buying WAL.
How it worked
- Detected the framework (Next.js, Vite, Astro, Nuxt, SvelteKit, Remix, Angular and more, monorepos included) and built the repo in a throwaway Cloudflare Container
- Checked that the output was a safe static site and worked out the exact WAL and SUI cost before publishing
- Published from a platform wallet, so users never needed one
- Redeployed on every push to main through GitHub webhooks, with commit-pinned deploys, encrypted project secrets and live build logs
- Came with a hosted MCP server and API keys, so agents could deploy too
The deploy step itself is a small public CLI, walrus-deploy, that wraps Mysten’s site-builder and takes care of SPA routing, MIME types and cache headers.
Tech Stack
- React 19, Vite and Tailwind
- Hono on Cloudflare Workers with D1
- Cloudflare Containers for builds
- Walrus and Sui
The hosted version isn’t running anymore, so the code is the place to look.
