The agent is still right where you left it — dev server running, preview URLs live, conversation preserved. Aether snapshots your workspace between turns and resumes it in milliseconds, so follow-ups feel instant instead of async.
Most cloud agents rebuild from scratch every time you come back. Aether keeps the workspace warm — so what used to be an async handoff is now a conversation.
Your PR's CI goes red. Aether wakes the exact VM that shipped that commit — in under a second. Failing test already in memory, logs in the terminal, agent context intact. It investigates and pushes a fix before your next coffee sip.
Come back to a PR after lunch. The agent resumes the same workspace that opened it — not a fresh one — and picks up the existing thread of reasoning. No re-ingesting the repo. No asking the same clarifying question twice.
preview.runaether.dev/pr-1847 stays live between turns. Share it in Slack, pass it to QA, let your PM click around. When the agent comes back to iterate, the server is still running — not restarting.
A full dev environment — file editor, terminal, exposed ports, agent context — snapshotted between turns and resumed in milliseconds. Jump in and debug it like it's your laptop.
No screen-share. No SSH. No guessing what the agent is doing. Open a task and you're inside the VM — live file tree, real terminal, one-click port forwarding. Nudge the agent, run a test yourself, close the tab and walk away.
Because resume is fast, the agent can come back as often as it needs to. It owns the PR until merge — fixing CI, replying to reviewers, rebasing on main. You review the final result, not every interruption.
Most agents stop the moment the first diff goes up. Real PRs aren't that clean — CI flakes, reviewers push back, main moves. Aether stays on the task until it's merged, waking the same workspace each time.
Everything else we built so the agents actually work in production.
True VM isolation — not shared containers. Snapshot and resume at the microVM layer, with per-task kernel boundaries. Pick Small, Medium, Large, or XL.
Your most-used projects stay pre-snapshotted with services running. Sub-second resume — dev server up, node_modules cached, agent conversation and TypeScript server all intact.
Teach the agent your conventions with a simple markdown file in your repo. Skills, lint rules, PR style — all respected automatically.
Encrypted at rest, decrypted only at VM boot, wiped on shutdown. Per-project scoped. Egress allowlisted. Rotated independently of the workspace.
Every agent turn, tool call, file change, and terminal command streams to a durable log. Replay any run end-to-end — audit, debug, or resume from any point.
Commits author as @aether-agent[bot], not your personal GitHub account. Scoped permissions, auditable history, no contamination of your contribution graph.
Every plan includes monthly credits for VM time plus always-warm slots. You bring your own Codex or Claude Code subscription — we don't mark up tokens. 1 credit ≈ 6 min on a Medium VM.
Spin up your first always-warm slot in under a minute. Free during beta.
