Replicas
Run any coding agent harness in the cloud
About Replicas
Replicas is a background coding agent that allows you to delegate tasks to Claude Code or Codex from Slack, Linear, GitHub, and more. Each task works inside of a sandboxed virtual machine, allowing teams to heavily parallelize work and burn through tickets. Replicas agents output higher quality PRs via feedback loops - each task automatically is notified and fixes CI failures and reads all code reviews. With Environments, engineering teams can configure agents to run their entire codebase locally, verify its work, and provide preview URLs.

Made switching between agents feel instantaneous - time to first load is now <5ms, <100ms for consistency.
Made switching between agents feel instantaneous - time to first load is now <5ms, <100ms for consistency. This is a lot harder to do when the sessions are cloud agents: - Source of truth is NOT your laptop - Traffic navigates through backend + sandbox proxies - Inactive

A month ago I dropped out of Waterloo and turned down a job offer to join @tryreplicas as CTO Last week @connortbot and I presented at YC P26 demo day Best decision I've made YC compresses years of lessons into weeks, and joining mid-batch only amplified it. The founders Show more
