In two months, two vendors walked back self-hosting and harness freedom. Cognition put self-hosted Devin into maintenance mode. Anthropic blocked third-party harnesses on the Claude Code subscription. If your agent runtime depends on one vendor's billing model, regional availability, or ban policy, your team is one announcement away from a forced migration. Here is what a self-hostable runtime actually has to give you, and where Nairi is honest about the line between what runs on your hardware and what does not.

Claude Code, Cursor agents, OpenCode, Devin. Every AI coding agent on the market is built for one developer at a time. That is an architectural choice, not a missing feature, and it holds until the moment a second human needs to read or continue what the agent did. Here is where the single-user assumption breaks and what multi-user actually requires.

In 2026, AI agents in shared Slack workspaces hit their first wave of public trust incidents: a worm-like growth hack, org-wide bans, a supply-chain backdoor, a privilege-escalation CVE. None of them are one vendor being reckless. They are the same missing primitive, a permissions model a buyer can actually reason about. Here is the pattern, what buyers are asking for, and what Nairi ships today.

Devin's ACUs, Cursor's compute budget, Lindy's per-seat fees, Zapier's tasks, Viktor's credits, Claude Code's weekly limits. Every flagship AI agent has at least one viral pricing complaint. Here's what predictable agent pricing looks like instead, and where Nairi lands.

Anthropic shipped Claude Tag this week. The product is good. The architecture it pushes you toward is the part worth thinking about before you adopt.
