From ideas to features.

A software factory for coding agents. Product design, tech design, code and review, in one workflow.

Join the private beta waitlist

One workflow, end to end.

Each card moves through the same stages. Agents do the work at every stage, and the workflow stops for you at the ones marked You.

  1. 1 You

    Product design

    An agent drafts the product document and a clickable prototype, or you shape them together in a session. You review them before any code.

  2. 2 You

    Tech design

    An agent writes the technical design from the approved product. You comment, then approve.

  3. 3

    Implementation

    A worker builds the approved design and opens a pull request on GitHub.

  4. 4

    Agent review

    A second agent reviews the change against the design. Fix rounds run until it passes.

  5. 5 You

    Site review

    Try the change on a preview. Leave notes on the page with the widget, then approve.

  6. 6

    Done

    The pull request merges and the card moves to Done.

Everything the factory needs.

Product design: nightly price on search cards v1 Finish review

Guests compare cabins from the search page. Each card shows a photo, the name and the rating.

The card adds the nightly price and the total for the dates, so a guest never opens a cabin only to learn its price.

YouPut the total first. That is what guests compare.

Works with

Bring the agents and the tools you already use. Workers run on your machine, on your own subscriptions.

  • Claude Code Runs any stage, or an interactive session.
  • Claude Design Store a Claude Design canvas as an artifact, and link it to a card.
  • Codex Runs any stage, with its own models.
  • OpenRouter Other models, through a Codex profile.
  • GitHub Pull requests, checks and reviews.
  • MCP Any MCP client can read and write the board.
  • More coming More agents and forges are on the way.

What you need

Loupe brings the workflow. You bring the agents.

  • Claude Code or Codex On your own subscription or API key.
  • A GitHub.com repository with the Loupe GitHub App The app lets Loupe read pull request status and move cards. GitHub Enterprise and other forges are not supported yet.
  • A Mac or Linux machine for the bridge The bridge starts the workers, so it must be running while work happens.
I'm all set, I want in!

Loupe is even better with

Optional, and worth the few minutes they take to set up.

  • A GitHub account for your agents A second account opens the pull requests, so you can approve them.
  • Preview deployments A URL for each pull request lets you review the change with the site review widget.
  • A worktree script The bridge runs it before each worker, so workers run side by side in their own checkout instead of sharing one.
