Aether Review 2026: Turn Your AI Subscription Into a Fleet of Devboxes

You already pay for an AI subscription. Aether points it at a fleet of devboxes so one agent becomes many.

What is Aether?

Aether (runaether.dev) is a cloud devbox platform for AI agents. You delegate a task, fix, or review; an agent streams every command and diff live; it opens a pull request; and a second agent reviews, requests changes, and re-approves until the checks pass. Visual changes ship with a Playwright video, screenshots, and the full review thread as “receipts.”

Key features

• Watchable loop: every command and diff streams as it lands; step in and take over at any point
• Plan mode: the agent proposes, you approve, then executes; queue follow-ups mid-run without restarting
• Agent-reviewed PRs: opened, reviewed, fixed, and re-reviewed until green
• Receipts: visual PRs include a Playwright video, screenshots, and the review thread
• Fleet: one subscription becomes parallel isolated devboxes running while you sleep
• Bring your own model: Aether bills only for compute; the LLM runs on the subscription you own

Who should use it?

Engineers who want to parallelize grunt work — fixes, reviews, dependency bumps — across isolated environments without paying twice for intelligence they already subscribe to.

Pros and cons

Pros: charges only for compute, not a second AI bill; truly interruptible; the review agent catches real regressions; visual receipts make UI review concrete; idle devboxes bill nothing.

Cons: tied to a supported AI subscription; free tier is thin (≈4 hours/month); credit math needs planning for big jobs; early-stage pricing/SLA still settling; receipt reliability depends on the agent exercising the UI.

Pricing

Free tier (20 credits ≈ 4 hours/month) plus Starter $30, Pro $75, Max $120 per month. 1 credit = 12 minutes on the default devbox; Medium 2x, Large 4x, XL 8x; idle bills nothing.

FAQ

Do I pay for the model twice? No — you bring the model via your existing subscription; Aether charges only for compute.

What are receipts? For PRs with visual changes, Aether attaches a Playwright video, screenshots, green checks, and the review thread so you can verify the change actually ran.
