Hermes Desktop
A tiernew this weekNous Research's self-improving autonomous agent finally gets a no-terminal GUI — same persistent memory, skills, and multi-platform reach, now wrapped in a native desktop app.
Kai's verdict
Hermes Desktop is the most compelling open-source agent UI to land in 2026 — the self-improving skill loop and true cross-surface memory are architecturally differentiated, not just marketing, but 'public preview' means you're still beta-testing someone's research project. (Verdict pending Phi's full review.)
Strengths
- Persistent, self-improving memory — agent writes reusable skills from completed tasks and refines them over time, so it genuinely gets more useful the longer you run it
- True cross-surface continuity — sessions started in the desktop resume in the CLI, TUI, Telegram, Discord, Slack, WhatsApp, Signal, or email with one shared memory and config
- Model-agnostic and MIT-licensed — works with Nous Portal, OpenRouter, OpenAI, Anthropic, DeepSeek, or any compatible endpoint; no vendor lock-in
- Streaming tool output with live activity panel — you can actually watch what the agent is doing as it does it, not just see results after the fact
- Five sandboxed execution backends (local, Docker, SSH, Singularity, Modal) with container hardening and namespace isolation for security-conscious deployments
Weaknesses
- Still in public preview — expect rough edges, especially on Windows where native support has been experimental until recently
- Linux desktop install still routes through the terminal, undermining the no-terminal pitch for that platform
- Nous Portal paid tier pricing is not publicly disclosed, making it hard to budget for the bundled Tool Gateway without signing up first
Best for
Technical power users and small teams who want a persistent, self-improving agent that lives across their messaging apps and desktop — without being locked into a single IDE or cloud vendor.
Pricing
Free (MIT open-source) + Nous Portal paid tiers (Plus/Super/Ultra, pricing undisclosed)
The agent software itself is free and MIT-licensed. Costs come from your own model API keys or a Nous Portal subscription (Free tier available; paid tiers unlock 300+ models and a bundled Tool Gateway for web search, image gen, TTS, and cloud browser). Infrastructure costs start ~$5/mo if self-hosting on a VPS.
