Early accessPrototypes
Test your idea with a version that works.
Flinter builds a working version of your idea, with real screens, real data and buttons that do things. Share the link, see how people use it, and change it in plain words.

How Flinter helps
Test your idea before you spend months building it.
Most ideas are tested too late, after months of design and engineering. Mockups help, but people can’t use them like a real product. Flinter builds a working prototype from one sentence, so you can test with real people now.
01The problem
“Mockups don’t show how the idea really works.”
Testers click through still screens and guess. You learn about the design, not about the idea.
How Flinter solves it
A prototype with real screens and real data.
Sign-in, forms and saved data that work, so people try the real thing.
02The problem
“Building a prototype takes too long.”
Weeks of building before the first test means fewer tests, and less to learn from.
How Flinter solves it
From one sentence to a link you can share.
Describe the idea, and Flinter plans and builds the screens. Share one link with testers, investors or your team.
03The problem
“Each round of feedback means starting again.”
Changing a prototype often means rebuilding it, so teams stop testing.
How Flinter solves it
Change it in plain words and share it again.
Ask for the change, and the next version is ready. Every version is kept, so you can go back to one that worked.
What you get
From an idea to something people can try.
From one sentence
Describe the idea the way you’d tell a friend. Flinter plans the screens and builds them.
Real screens and data
Sign-in, lists, forms and saved data that work, so people try the real thing.
A link to share
Send one link to testers, investors or your team. They open it in the browser, with nothing to install.
Change it in plain words
Ask for a change, and the next version is ready to share again.
Every version kept
Try a new direction, then go back to any earlier version in one click.
Ready to grow
When the idea works, keep building on the same project, or export the code to GitHub.

Questions
Good questions,
straight answers.
What people ask before they join. If yours isn’t here, ask the team.
Still wondering?Ask the team anythingDescribe the idea in one sentence, like an app where neighbours lend each other tools. Flinter builds the screens with sign-in and data. Share the link, collect feedback and ask for changes in plain words.
Yes. It has real screens, real sign-in and real data, and you can keep building it into the finished product.
You decide. Share a preview link with the people you choose, or publish it on your own domain when it’s ready.
Yes. Export the code to GitHub at any time, and your developers can keep working on it there.
