Hey Product Hunt! 👋 I'm Connor, CEO of Replicas, here with my co-founder Saai. We're super excited to finally share Replicas with this community. Why we built this Like many of you, we think the future of software engineering is delegating to fleets of cloud agents. Engineers are already using their preferred harnesses: Claude Code, Codex, Opencode, Pi, and others everyday. But back then, no one had made a good way to use them on cloud. Every existing solution either locks you into one specific harness, or forces you to run agents locally on your machine. That means your agent stops the moment you close your laptop. And if you want multiple agents running at once, you're left wrangling git worktrees, hoping your computer doesn't crash, and buying a clamp to keep your computer open. What Replicas does Replicas runs your agents in isolated cloud VMs. Each one gets its own full dev environment, installs your dependencies, spins up your database, and runs your actual codebase locally inside the sandbox. It works with Claude Code, Codex, OpenCode, and more. You bring your own API keys or subscriptions, so you only pay for the infrastructure. Trigger it from wherever you already live: mention @replicas in a GitHub PR, ping it in Slack, assign a Linear issue, or hit the API. You come back to a PR ready to review. What we've seen We dogfood this hard: 95% of our own lifetime PRs were shipped with Replicas, and we haven't opened a single one without it in the last 3 months. Our customers average 30% of PRs through it too; teams like Mintlify, Knowunity, and Composio. The use cases have gone way beyond what we initially imagined: personalized code review, automated code quality checks in CI, security reviews and pentests, auto-triaging issues, and teams running around-the-clock on-call support engineers. This is just the beginning of what's possible when you can run agents in parallel, in the background, around the clock. We'd love to hear how you're thinking about AI agents in your stack! Drop a comment or just come say hi, we're here all day. 🙏
