We're a design agency juggling a lot of client projects. How do prototyping tools handle per-project permissions, guest reviewers, and client-facing sharing?

“Figma for broad design collaboration and flexible sharing.”

“Paid plans also offer additional sharing controls, including password protection and, on Enterprise, link expiration.”

“One consideration: Figma is transitioning its project structure to folders, so it's worth checking the current permission behaviour of your plan.”

“Framer | Strong | Project members | Strong | Website design and interactive client projects”

“Framer | Strong | Project members | Strong | Website design and interactive client projects”

“Framer for project-specific website collaboration and publishing controls.”

“Agency advantage: Worth considering if open-source software, flexibility and control over infrastructure are priorities.”

“One thing to investigate is whether its team-level membership model gives you enough isolation for your particular client workflow.”

“Sketch | Very strong | Yes, document-level | Strong | Agencies wanting controlled document sharing”

“Sketch for document-level guest permissions and access management.”

“Sketch is particularly interesting here: its Guests can access only the documents explicitly shared with them, and its permissions directory helps administrators review and revoke access.”

“An interesting example is Proto.io, which supports both live prototype links and snapshots.”

“It also supports reviewer-restricted sharing.”
