into a dev team.

Run your first agent free

Interactive demo of the Aether app, with three selectable stories. Start an agent: the new-task composer types a prompt, a devbox boots in about five seconds with a live terminal, file tree, and a shareable preview link on port 3000, and the agent fixes a broken mobile order summary, captures before-and-after screenshots and a session video into the thread, asks one question, and opens pull request #1851 with a preview link and passing checks. The review loop: aether review requests changes on a pull request, the agent folds both fixes in, and the re-review approves. PR review: the reviewer surface at /pr-reviews streams three inline findings onto a pull request and posts a changes-requested verdict. Buttons inside the demo switch tasks and pages and answer the question; the pause control freezes all motion.

Oversight

A loop you can watch and take over.

Every command and diff streams as it lands — watch the whole run, or step in and take over at any point.

  • Plan mode: the agent proposes, you approve, then it executes
  • Queue follow-ups mid-run and the agent folds them in without restarting
  • Stop the agent anytime and the devbox stays alive, yours to use

Demo: an agent streams commands and diffs into the task thread while a typed follow-up queues without interrupting it; in a separate pane, the human runs npm test in their own terminal and the suite passes.

Review

AI that never ships its first draft.

Shipped by an agent. Reviewed by an agent. Approved by you.

Demo: Aether opens a pull request, its review agent finds a double-charge bug and requests changes, the author agent pushes a fix, the review approves, and the pull request resolves with passing checks.

0:00 / 0:00

Every PR the agent opens is reviewed, fixed, and re-reviewed in GitHub until the code holds up.

Receipts

Seeing is shipping.

Every PR making visual changes arrives with the receipts: a Playwright video of the change actually running, screenshots, green checks, and the full review thread.

I'd bet my on-call shift on this one. Reverted the fix and the new duplicate-delivery test caught the regression. ✓

Fleet

Your subscription, multiplied.

Point the subscription you already pay for at Aether and one agent becomes a fleet — parallel isolated devboxes, running while you sleep.
