Running AI agents without heavy compute: benchmarks, setup guides and comparisons. RSS.
I measured the RAM usage of 6 AI agent harnesses on a $5 VPS
Idle and active RAM for Gray, OpenClaw, Hermes Agent, ZeroClaw, nanobot and NanoClaw on the same $5 VPS, with the method and scripts to reproduce it.
What is an AI agent harness?
An AI agent harness is the software that turns a language model into a working agent. What it does, how it differs from a framework, and how to choose one.
How to run an AI agent 24/7 without a GPU
You don't need a GPU to keep an AI agent running around the clock. How to do it on a small server with Gray, a hosted model and a cron job.
OpenClaw alternatives for people who want something simple
OpenClaw does a lot, and that comes with setup and security work. Simpler alternatives — Gray, ZeroClaw, nanobot, PicoClaw, NanoClaw — and when each fits.
