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.
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.
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.
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.
Keep going. Build a prototype in Lovable or Cursor, then ask your assistant to publish it to PeerLink when it’s ready for your team.
PeerLink is in early access. Tell us what you’re building and we’ll get you set up.
