COMPARE

jsdrop vs StackBlitz

StackBlitz runs Node.js in the browser with WebContainers, so full-stack framework projects run without a server. jsdrop also runs Node.js in your browser, but keeps a drop to a single program and gives its server a public URL.

Try jsdrop free No sign-up needed.

What both do well

  • Node.js and npm running in the browser.
  • Shareable projects and embeds.
  • AI-assisted editing.

Where jsdrop stands out

  • Two files and nothing else: index.ts for the program and package.json for its dependencies. Imports you forget to list are added on Run.
  • When your program calls listen(), it gets a public tunnel URL that anyone can open while your tab runs it.
  • Live collaboration is free: share the editor link and edit together with live cursors, even as a guest.
  • Permanent versions: every save creates an immutable snapshot you can link to, restore, or fork.
  • Pro deploys up to three drops to run around the clock in a sandboxed container, redeployed on every saved version, with logs.
  • A REST API and an MCP server, so scripts and AI assistants can create, edit, and deploy drops.

Where StackBlitz is a great fit

  • Full-stack framework projects, such as Next.js, Nuxt, and SvelteKit.
  • Many files, a terminal, and each framework’s real tooling.
  • Bolt, an AI builder for complete web apps.

Which should you use?

Choose StackBlitz for front-end and full-stack framework projects. Choose jsdrop for a back-end program you want to share, call from outside, or keep running.

Questions

Can people outside my browser reach a jsdrop server?

Yes. When your program calls listen(), jsdrop shows a public tunnel URL that works while your tab runs it.

How do I keep a server running after I close the tab?

Deploy it with Pro. Up to three drops run around the clock on jsdrop’s servers and redeploy on each saved version.

Is jsdrop free?

Yes. Public drops, running in the browser, collaboration, and versions are free; Pro adds deploys, secrets, custom domains, and private drops.
