Codex Infinity

What is Codex Infinity?

Codex Infinity is a platform for running autonomous coding agents in the cloud. You pick a harness, meaning the agent loop and tools such as Codex, Claude Code, Gemini CLI or Pi, and pair it with a model from OpenAI, Anthropic, Google or open-weight options, optionally adding a second harness as a subagent. Tasks can be submitted from a CLI with codex cloud exec, from the REST API, or by mentioning the bot in a GitHub pull request comment, and several agents can work on one codebase in parallel. Each agent gets its own sandbox with toolchains and GPU access. The site also lists a SQL studio with charts, always-on CI monitoring, built-in Git hosting called Infinity Git, and add-ons such as Postgres, Mongo and auth services. Pricing lists a free self-hosted open-source CLI and a Cloud Platform plan at $24 per month, where you bring your own model keys and compute is billed on actual use.

Use cases

• Run a coding task and let the agent finish it
• Run several agents on one codebase in parallel
• Fix failing tests from a pull request comment
• Monitor CI for regressions and failing builds
• Query databases and chart results
• Host Git repositories with agent access

Who it's for

• Software developers
• Engineering teams
• Agent builders
• DevOps teams

Why use Codex Infinity

• You can choose the agent and model combination instead of being tied to one vendor.
• Agents run in isolated sandboxes, so a failed attempt does not touch your local machine.
• Tasks start from the CLI, the API or a GitHub comment, which fits existing workflows.
• A free open-source CLI path exists for people who prefer running locally.
• Flat orchestration pricing is separate from model costs, which you pay your provider directly.
