Epho

Epho is an API that spins up AI coding agents — Claude Code, Codex, or OpenCode — in cloud sandboxes. You send a single POST request with a prompt, repo URLs, files, and MCP server configs, and Epho streams back the agent's output in real time. There's no SDK to install, no daemon to run, and no infrastructure to manage on your side. It's a straightforward way to turn a prompt into code changes without leaving your terminal or CI pipeline.

Under the hood, Epho boots a fresh environment with the agent you choose, clones your repositories, attaches any input files, and wires up your MCP servers. The whole run streams back as server-sent events — tokens, tool calls, diffs, and the final answer. You can also use the async endpoint to fire off a task and pick up the result later via webhook. Chats are durable: a sandbox pauses between turns and resumes with the same filesystem and agent session, so you can have multi-turn conversations with the same context. Epho supports bring-your-own provider keys, and some free OpenCode models don't require any key at all.

This tool is built for developers who want to automate coding tasks — think PR reviews, refactoring, bug fixes, or data reconciliation — without babysitting a local agent. It's also useful for CI/CD pipelines, cron jobs, or any script that needs to make code changes programmatically. If you can write JSON, you can use Epho. It's minimal, fast, and honest about what it does.
