The release of Proliferate provides an open-source, self-hostable execution sandbox and evaluation harness designed to run coding agents entirely on your own infrastructure. This enables production engineering teams to execute and benchmark untrusted agent-generated code within secure, private network boundaries without relying on proprietary cloud runtimes. This transition to self-hosted agent execution removes third-party compliance risks and eliminates the variable API costs associated with hosting agent sandboxes.
Proliferate is an open-source, self-hostable alternative to GitHub Copilot that lets you run codex-style agents on your own infra. This matters because it removes vendor lock-in and cloud costs for teams already running LLMs in production—you can now ship the same “issue-to-merge” automation on-prem or in your VPC without sending telemetry or code off-cluster. Expect lower latency, tighter compliance, and the ability to fine-tune the agent on your private codebase, but you’ll need to budget GPU cycles and ops time to keep it running.
