The useful distinction

People look past Railway cloud agents when they need something to call from code: the agents are interactive VMs in Priority Boarding, with no documented task API or pull request flow.

The useful split is who builds the agent. Most products here run their own. Rush runs Claude Code, Codex or OpenCode, the vendors' own CLIs, and returns the result with the record of how it was made.

Depth

In depth

Claude Pro $20 / month; Max 5x $100 / month. Checked 15 September 2026.

Claude Code on the web

You only run Claude Code and want Anthropic to host the VM inside your Claude plan.

The same Claude Code harness, hosted on Anthropic VMs. Connect GitHub, submit a task, review the PR. Status: research preview.

Clones a GitHub repo, pushes a branch, opens a PR from the web UI. GitLab/Bitbucket are bundle-only and cannot push back.

Taps out. Research preview. GitHub required to push. Zero Data Retention orgs cannot use cloud sessions. IP allowlists break Anthropic-hosted runs. Claude-only.

ChatGPT Plus $20 / month; Pro 5x $100 / month; Free includes limited Codex. Checked 15 September 2026.

Codex cloud

You are on ChatGPT and want OpenAI's agent in a box, included in the plan.

OpenAI's coding agent, running background tasks in isolated ChatGPT cloud environments. Included with ChatGPT plans. Not the 2021 Codex model.

Connect GitHub or GitLab (Beta). Review the summary and diff, then open a PR. @codex on issues and PRs.

Taps out. API-key path has no cloud, GitHub review, or Slack. Agent internet is off by default. Cloud chats can cost more than local.

Hobby free (pay-as-you-go orbs); Individual $20 / month includes 45,000 orb minutes. Checked 15 September 2026.

Amp orbs

You use Amp and want threads that keep running on a remote machine, with multiplayer prompting.

Amp's frontier agent on remote machines (orbs) that keep working when the laptop is closed. Separate company from Sourcegraph as of 2 Dec 2025.

GitHub App acts as you. gh is preinstalled. Docs tell you to put gh pr create in AGENTS.md for automatic PRs. GitHub Enterprise Server is not supported.

Taps out. Burst limit of 20 metered orbs. Multiplayer exposes secrets and the terminal to the workspace. GHES unsupported.

Free trial; Pro $60 / month with $60 of usage, up to 5 users; Max $200 / month. Checked 17 October 2026.

Tembo

You want more harnesses than three, three forges and Sentry or PagerDuty triggers.

An agent orchestration platform that runs Claude Code, Codex, Cursor, Amp, OpenCode or Pi in a dedicated cloud VM per session, from GitHub, Linear, Jira, Slack, Sentry or PagerDuty events, and opens pull requests.

Opens pull requests on GitHub, GitLab and Bitbucket, including coordinated pull requests across repositories.

Taps out. Pro caps at 5 users and medium sandboxes. Sandboxes are destroyed after the session. The API documents no webhooks. API keys expire after 90 days by default.

Free with limited cloud agents; Build $20 / month with $20 of usage at API rates; Business $50 / user / month. Checked 17 October 2026.

Warp Oz

You already live in the Warp terminal and want the same agents in the cloud from Slack, Linear or GitHub Actions.

Warp's cloud agent platform. It starts Warp Agent, Claude Code or Codex runs from a CLI, an API, Slack, Linear or GitHub Actions, in Docker-based sandboxes on Warp or your own compute.

Pushes branches and opens pull requests on GitHub, authored by the Warp Factories GitHub App with team authorization.

Taps out. Free has limited cloud agents. Self-hosted execution is Enterprise only. Build-plan concurrency is still being finalized. GitHub is the only documented forge.

Pro $20 / month; Teams Standard $40 / user / month. Checked 15 September 2026.

Cursor Cloud Agents

Your team is standardized on Cursor and wants the same Agent off the laptop.

Cursor's local Agent, moved into isolated cloud VMs. Formerly called Background Agents. Available on paid Cursor plans.

Works on a separate branch and opens a draft PR. GitHub, GitLab, Azure DevOps, Bitbucket Cloud.

Taps out. Requires a paid Cursor plan and an environment snapshot. Multi-repo long-running is not available. Move-to-cloud drops uncommitted files. Prompt-injection risk is documented because commands auto-run.

Rush

What Rush is

Rush is the alternative for the part Railway does not document yet: starting an agent from code and getting a pull request back, with the run visible to the org.

Honest limits

Skip Rush if

  • Rush runs three agents: Claude Code, Codex and OpenCode. It does not host an agent you wrote yourself.
  • Repositories come through the Rush GitHub App. A GitLab or Bitbucket repository cannot be a run's repository yet.
  • There is no self-hosted or customer-VPC deployment, and we do not publish a compliance report today.
  • Compute is metered. Free includes 5 agent-hours a month and Pro 40, each with a weekly ceiling.
  • You review the pull request. Rush does not merge for you.

FAQ

Questions people actually ask

What is the best Railway cloud agents alternative?

It depends on the part of the job you want to keep. Use Claude Code on the web if you only run Claude Code and want Anthropic to host the VM inside your Claude plan. Use Codex cloud if you are on ChatGPT and want OpenAI's agent in a box, included in the plan. Use Amp orbs if you use Amp and want threads that keep running on a remote machine, with multiplayer prompting. Use Rush if you want to send a task by API or MCP and get back a pull request, report or files with the transcript.

Can I move from Railway cloud agents to Rush?

Railway cloud agents are in Priority Boarding with no task API, so there is no workload to migrate yet. Repository instructions in CLAUDE.md or AGENTS.md work on both.

Where does the code go when I leave?

Anything pushed to your GitHub remote stays there. That is the off-ramp on every product in this set, including Rush.
