Flitz SDK
A modified version of the Flutter SDK – 3.41 and up – that powers your preview builds.
Flitz for software engineers
Publish it. Share it. Move on.
Flitz builds a preview straight from your branch and gives you a link or a QR code to share – so feedback arrives before the PR, not three days after it.
I finished it an hour ago. It's still sitting in a PR, waiting on CI.
PR review, CI, sign-and-upload, distribution – today, that's the only path to getting feedback on your work. Hours, sometimes days, before anyone actually sees it. And when the feedback finally arrives, you've already moved on to something else – so you drop what you're doing, work out how the code you wrote days ago fits together again, and start over.
Your workflow with Flitz
1
Make your change
You work on the same branch, in the same workflow you already have. Nothing about how you write code changes.
2
Run a preview
You get a preview of your app and a link or QR code to go with it, in about a minute. No CI run to clear first.
3
Share the link in Slack, email, wherever
You paste it into Slack, email, wherever your team talks. Anyone who needs to see the feature opens it on their own phone, and you hear back before the PR is even up.
Feedback in minutes, not days
Same pipeline, same branch. The only thing that moves is where the first feedback happens.

What you actually integrate
Flitz CLI
Command-line tooling for publishing your work – build and push a preview from your branch.
Native plugins
Drop-in native plugins to embed in your application so it can load and run preview bundles.
Hosting platform
A hosting platform for the bundles – stores and serves every preview behind a shareable link.
What Flitz changes for you
Publish straight from your branch
Whatever's on your branch – finished or not – becomes a real, running app with one command. No PR required to show it. Without waiting for CI.
One link replaces every request for a version
Everyone who needs to see it – a designer, a PO, a tester – opens the same link or scans the same QR code, and gets your actual, stateful app running on their own device.
Instant feedback
Feedback arrives while you're still in the code, so a correction is a few minutes of work instead of a return trip days later. Less time spent re-reading what you already wrote, more features closed per sprint.

Does it work with my existing CI/CD?
Yes. Flitz complements CI/CD, it doesn't replace it. Your full pipeline still runs once, on a version that's already been checked out on a real device.
Do reviewers have to reinstall the app for every preview?
No. They install the host app once, then every new preview loads into it. Opening a second, third, or tenth preview is a single tap.
Who can open a preview link?
Only the people you share it with. Previews are scoped to specific recipients inside your organization, so an internal version never ends up on a public URL.
Can we host previews ourselves?
Yes. You can run Flitz on your own hosting, with support to fit it into your existing infrastructure and review policies.
Stop waiting on the pipeline to get feedback
Publish a preview from your branch and get feedback the same day, from a phone rather than a screenshot.
