## PeerLink vs Fly.io

Great for: Running apps close to users around the world.

The catch for internal tools: You package your app as a container and build your own sign-in. Apps are public unless you lock them down.

Choose PeerLink if you want a private tool for your team without touching servers or writing sign-in code.

## PeerLink vs Vercel

Great for: Websites and front ends, with a preview for every change.

The catch for internal tools: It’s built around a developer workflow of git and builds, and putting a site behind your team’s sign-in takes extra setup.

Choose PeerLink if you aren’t a developer and want sign-in and access control without any setup.

## PeerLink vs Retool

Great for: Internal tools built on top of company databases and APIs.

The catch for internal tools: You build inside Retool’s editor rather than with your own AI assistant, and pricing is per user.

Choose PeerLink if you’d rather describe a tool to your assistant than learn a new builder.

## PeerLink vs Lovable

Great for: Going from an idea to a working app in an afternoon.

The catch for internal tools: You build inside Lovable, your app runs on Lovable’s cloud, and published apps are public unless you add sign-in yourself.

Choose PeerLink if the tool holds team data and should only open for the people you invite.

## Use them together

Build a prototype in Lovable or Cursor, then ask your assistant to publish it to PeerLink when it's ready for your team.
