About Ellipsis

Ellipsis provides a managed platform for deploying cloud-based coding agents defined in YAML and invoked through a REST API. Users specify the agent harness, model, repositories, environment variables, and spending limits while the platform handles isolated sandboxes, permissions, budgets, and logging. Agents can be triggered by cron schedules, GitHub events, or other integrations, and run in dedicated cloud environments with pre-installed dependencies. The platform supports interactive sessions for development, automated code reviews posted directly to GitHub, and durable agent conversations tied to pull requests or issues. Observability features include session transcripts, token-level logs, and cost tracking across team activity. API endpoints allow programmatic creation of agents, session management, and structured output retrieval. The system is designed for teams automating repeatable workflows or building agent-powered applications without managing infrastructure.
