Epho
Epho (epho.io) is an AI agents-as-an-API platform that allows developers to run coding agents like Claude Code, Codex, and OpenCode in serverless cloud sandboxes via a single REST API request with streaming outputs, MCP support, and repository cloning.
What is Epho?
Epho (epho.io) is a cloud-based "agents-as-an-API" platform designed for software engineers, AI developers, and DevOps teams. It allows developers to run autonomous coding agents—including Claude Code, Codex, and OpenCode—in serverless cloud sandboxes via a single REST API endpoint. Featuring real-time Server-Sent Events (SSE) streaming, automatic repository cloning, Model Context Protocol (MCP) server integration, session persistence, and multi-provider failovers, Epho provides a turnkey backend for running coding agents in the cloud.
Epho provides a zero-setup REST API endpoint (
POST /api/v1/chat) that launches fully configured coding agent sandboxes in seconds. The platform supports multiple major coding agent harnesses (Claude Code, Codex, and OpenCode) with automatic provider failovers across underlying sandbox infrastructure. Supporting per-second billing starting at approximately $0.0000438 per second with a $10 initial trial credit, Epho enables developers to run autonomous code reviews, bug fixes, and data scripts in parallel without managing local background daemons or dedicated servers.

FAQ
What is Epho and how can Epho help me?
Epho is a cloud-based AI infrastructure platform that lets you run coding agents like Claude Code, Codex, or OpenCode directly in the cloud. Epho helps developers automate coding tasks without setting up servers, environments, or complex integrations. Instead of managing infrastructure, you can simply send a request and get results streamed back in real time.
How does Epho actually work?
Epho works through a simple API. You send a prompt along with your repository or files, and Epho spins up a secure cloud sandbox, configures the AI agent, and executes the task. Epho then streams back the results, including code changes, logs, and outputs, making the whole process seamless and automated.
What makes Epho different from other AI coding tools?
Epho stands out because it focuses on “agents-as-an-API.” Instead of running tools locally or configuring environments manually, Epho abstracts everything into one API call. It handles sandbox setup, model integration, and event streaming, allowing developers to focus only on building features.
What kind of tasks can Epho perform?
Epho can handle tasks like code generation, bug fixing, pull request reviews, data analysis, and automation workflows. Since it connects directly to your repositories, Epho can read, modify, and test code just like a real developer working in a live environment.
Does Epho support multiple AI models?
Yes, Epho supports multiple AI coding agents such as Claude Code, OpenAI Codex, and OpenCode. This flexibility allows you to choose the best model for your use case without building separate integrations for each one.
How does pricing work in Epho?
Epho uses a usage-based pricing model, where you pay for the compute time used by the cloud sandbox. Costs are calculated per second of usage, and new users often receive free credits to test the platform before scaling.
Who should use Epho?
Epho is ideal for developers, AI engineers, startups, and teams building AI-powered products. It’s especially useful for anyone who wants to integrate coding agents into their apps without managing infrastructure.
