Agents are easy to demo, hard to ship: identity, storage, permissions and more are the real backend

mardix · reddit · 2026-10-22

Developer mardix argues that agent demos are usually just "model + tools + loop," but production agents immediately need much more: identity/auth, persistent application data, vector/search, files, tool permissions, retries/background work, LLM usage tracking, and a clean way to expose capabilities.

That's the thesis behind his Singlebase: not another agent framework, but a backend an agent can actually use, including MCP access to app data and services. He asks the community what they always end up adding after the first prototype, sparking discussion on the minimal production agent backend.
