Ink, launched March 5, 2026 by Eternis AI, is an infrastructure platform for AI coding agents to deploy and manage full-stack applications without human intervention. Where conventional cloud platforms treat developers as the primary user, Ink exposes the same controls a human would reach for in a web console — directly to the agent, programmatically, via MCP (Model Context Protocol) and Skills.
The platform connects to eight AI coding environments: Claude Code, Cursor, Codex, Gemini CLI, Windsurf, Goose, Kimi Code, and VS Code. Through those integrations, an agent can push a deployment, read structured logs with level filtering and full-text search, pull live CPU, memory, and network I/O metrics, and adjust resource allocation — all in the same session where it wrote the code. A slow database query or failed upstream connection can trigger an autonomous resource change without a human in the loop. Supported runtimes span Node.js, Python, Rust, Go, Elixir, Zig, and static sites, deployed via Docker, buildpacks, or auto-detection.
Eternis AI first surfaced in November 2024 with Freysa — an adversarial blockchain game on Coinbase's Base network where players paid escalating fees attempting to convince an AI agent to release a live cryptocurrency treasury. That experiment grew into the Freysa Sovereign Agent Framework, an open-source architecture for autonomous agents using Trusted Execution Environments for distributed key management. Coinbase Ventures and Selini Capital led a $30 million round into Eternis AI in May 2025. Ink is the deployment layer the framework lacked.
Pricing is per-minute with no idle charges. The free tier carries a $2 credit and requires no credit card — a structure aimed at agents managing their own resource budgets rather than a human approving a monthly invoice. The company says agents can scale CPU and memory in real time through the same MCP interface used for logs and metrics, collapsing what is normally split across a code editor, a CI/CD platform, and a cloud console into a single programmatic surface.
Adoption will hinge on <a href="/news/2026-03-14-optimizing-web-content-for-ai-agents-via-http-content-negotiation">Cursor and Claude Code</a>, which together account for the bulk of serious AI-assisted development today. Eternis AI is counting on Ink's MCP endpoints becoming a default within those environments rather than an optional add-on users have to discover. The Freysa SAF's existing developer base gives the company a ready pool of early adopters — the real test is whether Ink pulls in teams with no prior Freysa exposure.
