Krock.io gives you two ways to share your work: a share link (a public URL anyone can open, no account needed) or a project invitation (adds a specific person by email with a set role). Use a share link for quick, open review; use an invitation when you want named people with controlled access. This article explains the difference, who can see what, where guest comments come from, and how to remove access.
Share link vs project invitation: quick comparison
| Share link | Project invitation | |
|---|---|---|
| Who can open it | Anyone with the URL | Only the invited person |
| Account needed? | No | Yes (their own Krock.io login) |
| Can be forwarded? | Yes — it’s public | No — tied to one email |
| Best for | Quick client review, casual feedback | Named collaborators and reviewers |
| Access controls | Password, expiry date, downloads on/off, comments on/off | Role (Collaborator or Reviewer) |
| How to revoke | Delete or expire the link | Remove the person from the project |
When should I use a share link vs an invitation?
Use a share link when you want the lowest possible friction — for example sending a cut to a client who won’t sign up, or collecting quick feedback from someone outside your team.
Use a project invitation when you want named people, controlled permissions, and a clear record of who did what. Invited people log into their own account and only see what their role allows.
How share links work
A share link is a public URL you generate for a project or specific stages. Anyone who has the link can open it — no account required.
Open a project (or a specific stage), click Share, and set any of these controls:
- Expiration date — the link stops working after a chosen day.
- Password protection — viewers must enter a password to open it (you can generate one right in Krock.io).
- Permissions — turn downloads on or off, and allow or block comments.
You can also share a link to a whole folder. Any new stages you add to that folder later become visible through the same link automatically, so you don’t have to reissue it.
Why can everyone see my share link?
Because that’s how share links are designed to work. A share link is public by nature: anyone who has the URL can open it, and it can be forwarded to others.
That’s what makes it frictionless — but it also means the link is only as private as the people you send it to. To limit access to specific, named people who can’t pass entry along, use a project invitation instead.
To keep using a link but tighten it, add a password, set an expiration date, and disable downloads in the link’s permissions.
How project invitations work
An invitation adds a specific person by email and gives them a role. Krock.io has five roles across two levels.
Workspace level:
- Owner — full control, including billing.
- Manager — runs everything except billing.
- Member — works across all projects, but can’t invite people.
Project level:
- Collaborator — can upload and delete files, but only in the specific stages they’re added to.
- Reviewer — can view and comment on shared stages, but never touches the files. This is the role for clients and stakeholders.
So invite someone as a Reviewer if you want feedback only, or as a Collaborator if you want them to contribute files to certain stages. Reviewers and clients you invite are always free — only Team member and Collaborator seats are billed, as explained in Understanding Member Seat Charges & Credits. For the full breakdown of what each role can do, see User Roles.
Where do “guest” comments come from?
A “guest” comment comes from someone who opened a share link and left a comment through it. Share links allow commenting unless you turn that off, and commenting this way doesn’t require an account — so the person shows up as a guest.
A guest can optionally leave an email if they want to receive replies to their comment, but an email isn’t required to comment. That’s why a guest sometimes appears with no name attached.
To stop guest comments, either disable comments in the share link’s permissions, or stop using a public link for that project and invite named Reviewers instead, so every comment is tied to a real account.
How to revoke access
To revoke a share link: open the Share window, find the link in the list on the left, and delete it or let it expire. Either one cuts off access immediately for everyone who had that link.
To remove an invited person: click Share, choose Invite people, and in the “Who has access to the project” list, click the X next to their name. Their access ends as soon as they’re removed.
