Replicas

Overview

Replicas lets engineering teams run background coding agents like Claude Code and Codex in isolated cloud sandboxes. By connecting tools like Linear, GitHub, and Slack, it allows developers to delegate tickets to autonomous agents that write code, run tests, and open pull requests. The platform provides fully configurable virtual machine environments with local previews and custom hooks.

What it does

• Spins up sandboxed virtual machines with repositories cloned and dependencies installed.
• Executes autonomous coding agent harnesses like Claude Code or Codex in the background.
• Runs applications locally, verifies test suites, and iterates on bug fixes.
• Opens GitHub pull requests automatically and syncs progress back to project management boards.

Who it's for

• Software Engineers
• Engineering Managers
• Startup CTOs
• DevOps Teams

Why it works

• Sandboxed execution environments allow safe, local code compilation and testing.
• Brings your own credentials to support flexible agent frameworks like Claude Code and Codex.
• Triggers seamlessly from existing team workflows like Linear, Slack, and GitHub.
• Automates repetitive ticket resolution to parallelize engineering work effectively.

Founder story

Founded in 2026 by Connor Loi and Saai Arora, Replicas was built to solve the bottleneck of managing background coding agents in software development. Headquartered in San Francisco, the startup provides cloud infrastructure to delegate coding tasks seamlessly.

Comparison overview

• Unlike single-editor AI assistants, Replicas functions as a background runner across multiple harnesses.
• It provides complete environment customization for sandboxed virtual machines rather than locking users into proprietary tooling.
