Pranav Sharan Introduces Aether, Cloud Coding Agents That Run Claude Code or Codex on Your Existing Subscription
Today we’re introducing Aether @aetherruntime. The fastest cloud coding agents in the world that you can use with your existing subscription Give it a task and just 20 seconds later your build is running on its own cloud machine. You can pick up from your phone, watch every line, and step in whenever you want as if it was local. Close the laptop. It keeps going. It runs Claude Code or Codex on the Claude or ChatGPT plan you already pay for so there’s not a 2nd AI bill. You only pay for the machine. When it’s done, if code review is enabled, a reviewer agent runs the code with the changes, which catches classes of bugs that can't be found from static analysis. Before building Aether I built infra at Apple, Uber, and HeyGen. I built Aether because the cloud agents I tried before all had drawbacks, and I couldn't imagine building something without it now. It’s free to start.
Context
Running existing coding agents in the cloud without a second AI bill makes always on agent work cheaper for individual developers.
Pranav Sharan (@pranavctl) built Aether (@aetherruntime). Cloud coding agents run tasks on remote machines so work continues when a laptop is closed. Claude Code and Codex are the coding agents from Anthropic and OpenAI.
Deep dive
Pranav Sharan (@pranavctl) posted on Nov 4 introducing Aether, which he called the fastest cloud coding agents in the world that work with your existing subscription.
According to the post, you give Aether a task and about 20 seconds later the build is running on its own cloud machine. You can pick it up from your phone, watch every line, and step in as if it were local, and work continues after you close your laptop.
Sharan says Aether runs Claude Code or Codex on the Claude or ChatGPT plan you already pay for, so there is no second AI bill, and you pay only for the machine. When code review is enabled, a reviewer agent runs the code with the changes, which he says catches bugs that static analysis cannot find.
He says he previously built infrastructure at Apple, Uber and HeyGen, and that Aether is free to start.
The speed claim is the maker's own and is not independently confirmed. The post also does not detail machine pricing.

What to expect next
Watch for developers to compare Aether with cloud agent options from OpenAI, Anthropic, Cursor and others on speed and price. Anthropic and OpenAI rules on using personal subscriptions in outside tools will matter for how long the model works. Machine pricing and team plans are likely next steps if adoption grows.
Independent tests of the 20 second start time and of the reviewer agent on real projects would show whether the claims hold up for larger codebases.
