Host what Devin produced, to show someone before it ships
Devin works the ticket and opens the PR. Publish the build when the person who needs to approve it doesn't read pull requests.

Why the last step is the slow one
Devin's output is a branch and a pull request — appropriate for engineering, useless for the designer, the founder or the client who has to say yes to how it looks. Between the PR and a full preview environment there's a gap, and it's usually filled by a screenshot that answers half the question.
What Devin gives you
- A pull request against your repository
- A branch you can check out and build
- Standalone pages and scripts produced along the way
Reviewers can't read code
The people whose approval you need often can't evaluate a diff, and shouldn't have to.
Preview infrastructure is a project
Per-branch environments are worth building once you need them constantly, not for one review.
Screenshots answer the wrong question
A picture shows how it looks. It says nothing about how it behaves.
Putting Devin output online
- 1
Check out and build
Pull the branch, run the build, and find the output folder with index.html in it.
- 2
Drop the folder in
Drag it into the box above — no repository connection, no configuration.
- 3
Share, then delete
Give the reviewer the address, get the decision, and remove it when you're done.
Worth knowing
- Name addresses after the ticket so several open reviews stay separable.
- Publish only build output — source folders won't fit and don't need to.
- Password-protect anything unreleased, especially if the address is guessable.
- Republish to the same address after acting on feedback so the reviewer keeps one link.
- Delete addresses once the work merges; it's one click and it keeps things tidy.
Questions
- Can I preview a backend change?
- No. Static hosting serves files, so this suits front-end work.
- Is it safe for unreleased work?
- Use a password. Without one, anyone who guesses the address can see it.
- Does it integrate with GitHub?
- No, deliberately — there's nothing to connect and nothing to authorise.
- How many previews can I have?
- As many as you like, each on its own address.
- What happens when I delete one?
- The address stops working immediately and every version of it is removed.
