I am super excited to launch a new agent primitive: Epho - run Claude Code in the cloud. 🚀 Epho is a cloud agent API: it allows you to spin up cloud sandboxes with Claude Code, Codex or OpenCode pre-configured. You can connect your repos, attach files, and use different agents. Send a prompt, get the result. Epho came out of our own struggles with building our own AI analyst: - Sandboxes give you bare machines; you need to configure them for agentic workloads. - Each agent behaves differently, and you need to build integrations with each of them. - Sandbox providers are not very reliable, which means you need to figure out a multi-provider strategy to avoid failures. - Logging, artifacts, input/output, event streaming, and all of the other operational aspects need to be figured out. We had to go through the pain ourselves. We got to a point where things got quite reliable, and it became more obvious to us that this should be a primitive on its own: send a POST request, get the events streaming back to you. Epho is an agents-as-an-API product: you send a request, it spins up a sandbox, configures the chosen harness, clones your repos, and kicks off the agent. It takes care of automatic fallbacks across different providers, handles auth stuff, and just streams back the events and outputs. Epho uses your own keys, which means you only pay for the infrastructure Epho spins up for you. You send your Anthropic / OpenAI / Opencode API keys, and Epho uses them. We don't charge you per token; we just charge the infrastructure per second. Epho aims to bring cloud agents into your products easily. Epho is publicly available today. You get $10 free if you sign up and verify your email, and you can run many hours of compute with that. You can use Opencode's free models to get started even without an API key and just play with it for free.
