Ellipsis

Ellipsis is a managed cloud platform for running autonomous coding agents at scale. Engineering teams define agents as YAML config files that live in their repositories, and Ellipsis runs them in isolated, ephemeral sandboxes to review pull requests, fix bugs, build features, and investigate production issues. Agents trigger automatically on cron schedules, GitHub pull-request lifecycle events, or @ellipsis-dev mentions, and can also be launched on demand from the dashboard, the REST API, or the `agent` CLI. The platform runs Claude, Codex, and Gemini models, enforces hard budget caps and scoped per-session credentials, retains zero source code, and provides full observability with audit trails and replayable execution. Ellipsis (YC W24) serves 400+ engineering teams across 67,000+ connected repositories.

Ellipsis publishes 1 API on the APIs.io network. Tagged areas include Company, Code Review, AI Agents, Coding Agents, and Developer Tools.

Ellipsis’ developer surface includes developer portal, documentation, API reference, getting-started guide, support, engineering blog, pricing, and 14 more developer resources.
