agentsky - cloud-hosted coding agents, one api for every harness

About AgentSky

Runs coding agents in the cloud so they keep working when your laptop closes. Pick a harness, Claude Code, Codex, Hermes or pi, pair it with a model, and reach it over one API. Billing splits in two: compute by the second while the machine is awake, and model tokens at published per-model rates. The detail worth knowing is that you can connect an existing Claude or ChatGPT subscription, in which case model usage costs nothing and you pay only for compute.

Key Capabilities

Agents keep running after you close the laptop, with a persistent machine per agent

One API across four harnesses: Claude Code, Codex, Hermes and pi

Compute billed by the second, and idle agents suspend to zero

Connect an existing Claude or ChatGPT plan and pay nothing for model usage

1 GB persistent disk per agent, included

No seats, no minimums, no setup

Standout Features

Bring Your Own Subscription

Connect an existing Claude or ChatGPT plan and model usage is free; only compute is billed. For anyone already paying for a plan they under-use, that removes the usual double-charge of hosted agents.

Billed by the Second, Idle Costs Nothing

Compute meters per second while the machine is awake and agents suspend automatically when idle, so a long-running agent that spends most of its life waiting is cheap to keep alive.

One API, Four Harnesses

Claude Code, Codex, Hermes and pi are reachable through the same call, each paired with a model of your choosing, which makes comparing them a config change rather than four installs.

Perfect for

Long agent runs that outlast a laptop session
Anyone already paying for Claude or ChatGPT who wants cloud execution
Comparing harnesses without maintaining four setups
Work that is bursty, since idle machines cost nothing

macOS app for running Claude Code, Codex, Cursor, and OpenCode side by side, each in its own isolated workspace, without wrangling git worktrees by hand. You bring your own agent subscriptions and keys. The paid Conductor Cloud tier moves those workspaces into Vercel sandboxes so agents keep running after you shut the laptop, and adds shared multiplayer workspaces plus an API.

Orca logo

Orca

Open-source Agent Development Environment for running a fleet of AI coding agents at once. Every task gets its own git worktree, its own agent terminal, and its own browser tab, so you can fan one prompt across several agents, compare the diffs, and merge the winner. It drives roughly 30 CLI agents you already pay for, including Claude Code, Codex, OpenCode, Cursor and Copilot, and ships on macOS, Windows, Linux, iOS and Android.

Parallel Code logo

Parallel Code

Free, open-source desktop app that dispatches AI coding agents in parallel, each in its own git worktree. It runs the real CLI agents you already trust (Claude Code, Codex, Gemini) side by side, then lets you review the diffs, merge the wins, and toss the rest.
