For product teams

Test the idea before the sprint

Turn a spec into a working app your users can actually click through — real sign-in, real data — and learn what works before engineering commits to it.

How Kernel 1 builds

Working, not clickable

Real flows with sign-in, data and the awkward edge cases.

Plan it together first

Agree the plan, then Swarmz builds exactly that.

Hand it to engineering

Standard code, synced to your GitHub.

Start with an idea

Pick one. Press start

Each idea is a real prompt. Press start and Swarmz builds it as soon as you've signed up — or copy it and make it your own.

A new onboarding flow

Sign-up to first value, ready for user tests.

Build a working prototype of a new onboarding flow for a budgeting app: sign-up, three setup steps, a mocked bank connection and an empty-state dashboard.

A feature to user-test

Something real enough to learn from.

Prototype a shared shopping list: invite a partner, add items together with live updates and tick them off, on desktop and phone.

A team decision log

Every decision, its context and its owner.

Create a decision log for our product team: each decision with context, options considered, an owner and a date, searchable and filterable.

Two pricing pages

Put both in front of people and compare.

Build two versions of a pricing page for our SaaS — three tiers, and usage-based — each with a sign-up form that records which version people saw.

Hand it over, don't throw it away

The prototype is standard React, TypeScript and Tailwind, synced both ways with a private GitHub repository. Engineering picks up where you left off — and what they push flows back into Swarmz.

Included

Built for how product teams work

Plan mode

Agree the plan, then build

Plan mode asks its questions up front and writes a plan you can edit, then builds exactly that.

Comments

Review it on the page

Pin comments on the live app, resolve them together, or send them straight to the AI.

Analytics

Watch real sessions

Publish the prototype and see where people click, hesitate and rage-click — with replays.

Questions, answered

Is it a real build or a clickable mock-up?

A real build: working screens, sign-in, a database and the states in between. Test users can sign up and use it like the finished thing.

Can engineering pick it up?

Yes. It's standard React, TypeScript and Tailwind, synced both ways with your GitHub repository, so it's a starting point rather than a throwaway.

Can the whole team work on it?

Yes. Invite the team to your workspace with owner, admin, editor or viewer roles, leave comments on the live app, and see who else is in the project.

Can I share it with test users?

Publish it to a link anyone can open. On Business you can publish privately instead and invite specific people.

Can I bring in our spec?

Yes. Attach PDFs, docs, spreadsheets or screenshots to your prompt — up to 10 files — and Swarmz reads them before it builds.
