Replicas

Replicas (tryreplicas.com), a Y Combinator (Spring 2026) company, runs end-to-end background coding agents in isolated cloud sandboxes. Teams delegate engineering tasks - from Slack, Linear, GitHub, GitLab, Sentry, the web dashboard, a CLI, or a native macOS app - to frontier coding agents (Claude Code, Codex, Cursor, OpenCode) that work in their own VM-backed workspaces with databases, environment variables, files, skills, and MCP servers, then open pull requests for review. The Replica API (OpenAPI 3.1, base https://api.tryreplicas.com/v1, bearer API-key auth) exposes environments, replicas/workspaces, chats, event streaming (SSE), repositories, automations (cron + webhook triggered), and Google Search Console tooling, plus an official hosted MCP server at api.tryreplicas.com/v1/mcp.

Replicas publishes 13 APIs on the APIs.io network, including Analytics API, API Keys API, Automation API, and 10 more. Tagged areas include Company, AI, Coding Agents, Developer Tools, and Automation.

The Replicas catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Replicas’ developer surface includes documentation, API reference, getting-started guide, signup flow, pricing, engineering blog, GitHub presence, and 22 more developer resources.
