Selene

The local-first designer workspace

Make the next design decision in the real product.

Selene turns conversations, visual review, and design-system context into reviewable React source—without making your team depend on one model, vendor, or hosted workspace.

Pre-alpha, open source, and designed to keep projects portable.

React source is the artifact.Local work needs no account.Every handoff has context.

Designed for the work between idea and merge

A design workspace that speaks product, not mockup.

Keep the conversation close to the implementation. Selene helps designers review the states and flows people will actually use, then produces context developers can trust.

01

Review the real states

Navigate live React screens, inspect empty and busy states, and pin threaded feedback to any point or region on the rendered artifact.

02

Choose your agent

Bring a local or custom coding agent through a portable adapter protocol. The workspace stays yours when your tooling changes.

03

Hand off with proof

Record a review baseline, see what changed afterward, and give developers the directions and provenance behind a decision.

Your first project

From clone to a useful review in an afternoon.

The web demo is an account-free way to see the core loop. When you are ready, run the same workspace locally and bring your own project context.

  1. 1
    Start with a working screen

    Open the demo, switch between live states, and pin the point or region you want to discuss.

  2. 2
    Keep review and AI direction distinct

    Start an artifact review thread for collaborators, or send a separate targeted change request to your coding agent. Export the portable workspace when the review is ready.

  3. 3
    Run Selene locally

    Clone the repository, install with Bun, and use the web or desktop workspace with no required hosted service.

    bun install --frozen-lockfile
    bun run dev:web
