About
Replicas builds background coding agents that let engineering teams delegate work from tools such as Slack, Linear, and GitHub. Each task runs in a sandboxed virtual machine, enabling parallelized ticket execution and feedback loops that automatically address CI failures and code reviews.
Market
Replicas competes in the cloud and background coding-agent market, providing an execution layer that accepts tasks from Slack, Linear, GitHub, GitLab, or its dashboard, runs them in isolated development VMs, and produces pull requests for review. Its differentiation is agent-agnostic orchestration—supporting multiple coding-agent ecosystems and users’ own credentials—combined with API and automation capabilities for parallel, CI/CD, and custom engineering workflows.
Replicas targets software engineering teams—especially startups and other engineering-native companies—that want to delegate and parallelize coding tickets from their existing development tools. Its materials identify use by 20+ YC startups and position the product for teams responsible for shipping, testing, and reviewing pull requests; the likely buyer or champion is an engineering leader or developer team.
At a Glance
Problem
Engineering teams have more scoped software work than developers can efficiently clear: tickets, bug fixes, failing tests, CI investigations, and code-review follow-ups. Conventional AI coding tools are often tied to an editor or a single agent harness, while existing cloud options can lock teams into one harness and provide little control over the development environment. The economic pain is slower shipping and developer time spent on repetitive implementation and verification; the “killer” use case is delegating a well-defined ticket, review finding, or CI failure and receiving a tested pull request while engineers continue with higher-value work.
Product / Service
Replicas is a cloud platform for background coding agents. A task can be initiated from Slack, Linear, GitHub, the dashboard, or an API, then runs in an isolated virtual machine with the repository cloned and its dependencies, databases, services, environment variables, and tools available. The agent can inspect and modify code, run commands and tests, investigate failures, and return a reviewable pull request or other concrete handoff. Teams can use Claude Code, Codex, Cursor, or Opencode and bring supported subscriptions, API keys, credits, or enterprise inference agreements, rather than being forced into one model ecosystem.
The delivery model is per-seat SaaS with usage measured by workspace minutes: a 14-day free trial is followed by Developer at $120 per seat per month, Team at $300, and custom Enterprise plans. The benefit is asynchronous, parallel engineering work that remains sandboxed, team-visible, and reviewable, while preserving control over repositories, credentials, environments, and inference economics.
Market
Replicas competes in cloud coding agents and AI developer tools, a market that includes editor- and ecosystem-led products such as Cursor, Devin, Codex, and Claude Code, as well as cloud-orchestration alternatives such as Tembo. Its positioning is to provide a common cloud workspace for multiple coding-agent harnesses, with stronger environment control and bring-your-own inference economics than more bundled or ecosystem-specific offerings. Its main use cases span issue-to-PR automation, bug fixing, end-to-end testing, flaky-CI investigation, automated code-review follow-up, and backlog cleanup.
The company appears to be early but commercially active rather than simply pre-launch. Replicas is backed by Y Combinator and says it is used by more than 20 YC startups; its website reports that customers use it to ship more than 30% of their pull requests and names companies including Mintlify, Composio, Helicone, Dart, and Chronicle Labs. It also launched publicly on Product Hunt in June 2026, ranking fifth for the day. Public evidence does not establish revenue, ARR, or retention, so traction is best characterized as early customer adoption rather than proven scale.

Replicas listed its signed and notarized desktop app for both Apple Silicon and Intel Macs. The download requires macOS 12 or later.
The YC Tier List profiled Replicas as a background coding agent that lets users delegate tasks to Claude Code or Codex from Slack, Linear, GitHub, and other interfaces.
Replicas published a deep dive into its V1 product, including Environments and the next steps for its background coding-agent platform.
Replicas announced its background coding agent for engineering teams. The product runs codebases in sandboxed environments, installs dependencies, runs services and tests, and opens pull requests; it can be triggered from Slack, Linear, GitHub, a dashboard, or an API.
Linear listed Replicas as an integration that turns Linear issues into pull requests through autonomous coding agents in isolated cloud workspaces. Users can assign an issue or mention Replicas, after which the agent works on the repository and posts the resulting pull-request link back to Linear.
