Building MVPs

From idea to launch, fast

Stop building features one at a time. Spawn parallel agents for auth, payments, and core features—ship your MVP in days, not weeks.

Parallel workspaces for every feature

Each part of your MVP gets its own isolated workspace. Auth, payments, and UI all build simultaneously while you focus on the big picture.

auth-feature
payments-api
landing-page
dashboard-ui

Watch the code come together

See exactly what each agent is building. Review diffs, suggest changes, and guide the implementation—all without context switching.

- const API_URL = "localhost";
+ const API_URL = process.env.API_URL;
export async function fetch() {
+ const token = await getToken();

One command to start

Describe your MVP and Sonars breaks it into parallel tasks. Each workspace runs in its own git worktree, keeping everything clean.

Why Sonars for MVPs

Build everything at once

Auth, database, API, frontend—each gets its own agent working in parallel. No more sequential bottlenecks.

Iterate without fear

Every experiment runs in isolation. Pivot your approach without breaking what already works.

Ship in days

What used to take weeks now takes days. Get to users faster and start learning sooner.

Focus on product

Let AI handle the implementation details. You make the decisions that matter for users.

The MVP workflow

1

Break it down

Split your MVP into independent chunks: landing page, auth, core feature, payments.

2

Spawn agents

Create a workspace for each chunk. Each agent works in its own git worktree.

3

Guide and review

Check progress, provide feedback, merge what's ready. Stay in control.

4

Launch

Deploy your MVP and start getting real user feedback.

"I built my entire MVP in a weekend. Four features, all built at once. This is how I always wanted to work."

Alex K.Solo Founder

"The git worktree isolation is brilliant. I can experiment wildly on one feature without breaking the others."

Sarah M.Indie Hacker

Common questions

How does parallel development actually work?

Each workspace runs in its own git worktree—a native Git feature that creates isolated copies of your repo. Multiple AI agents can work on different features without conflicts, and you merge them when ready.

Do I need to be technical to use Sonars?

You should understand code enough to review what the AI writes. Sonars is for developers who want to multiply their output, not replace their skills.

What happens when features need to integrate?

You control when and how to merge. Sonars shows you the diffs from each workspace, and you decide the integration order. The AI can help resolve conflicts too.

Is my code sent to the cloud?

Your code stays local. Sonars runs on your machine and uses the Claude API directly with your own API key. We don't store or process your code on our servers.
