Hermes WebUI vs Open WebUI is a real question — both are great, but they solve different problems.
Both projects are open source.
Both give you a clean web chat interface for AI agents.
Both are free.
But Hermes WebUI is purpose-built for Hermes. Open WebUI is a general AI agent UI.
This post breaks down which fits which user.
The Short Answer
Use Hermes WebUI if:
- You only run Hermes
- You want tight Hermes integration
- You care about Hermes-specific features (skills, memory, schedules)
Use Open WebUI if:
- You run multiple AI agents (Hermes + OpenClaw + Claude + ...)
- You want one UI for everything
- You're willing to lose some Hermes-specific polish
Run both if you have time — they coexist on different ports.

Round 1 — Setup
Hermes WebUI: clone repo, npm install, npm start. Localhost ready in 3-5 minutes.
Open WebUI: Docker run command. Localhost ready in 2 minutes.
Winner: Open WebUI by a hair on speed. Hermes WebUI by a hair on flexibility.
Round 2 — Hermes Integration
Hermes WebUI: native. Profiles, skills, schedules, memory all surfaced.
Open WebUI: chat works fine. Hermes-specific features harder to access.
Winner: Hermes WebUI.
Round 3 — Multi-Agent Support
Hermes WebUI: Hermes only.
Open WebUI: Hermes + OpenClaw + Claude Code + Ollama + many more.
Winner: Open WebUI.
For OpenClaw specifically, my deepseek openclaw post covers the harness comparison.
Round 4 — Mobile Responsive
Both work on mobile. Both responsive.
Winner: Tie.
Round 5 — Provider Switching
Hermes WebUI: dropdown for Anthropic, OpenRouter, Ollama, etc. Per-conversation switching.
Open WebUI: more providers configurable. Plugin marketplace for new ones.
Winner: Open WebUI by breadth.
Round 6 — Skill Management
Hermes WebUI: Skills tab. Install, edit, browse Hermes-specific skills.
Open WebUI: generic prompt template management.
Winner: Hermes WebUI.
For skill design specifically, my build your own openclaw post covers the architecture.
Round 7 — Memory Editing
Hermes WebUI: native memory tab. Edit Hermes memory directly.
Open WebUI: generic chat history. Doesn't expose Hermes memory cleanly.
Winner: Hermes WebUI.
Round 8 — Session Continuity
Hermes WebUI: sessions sync across CLI, Telegram, web. Single timeline.
Open WebUI: sessions are local to UI. Doesn't sync to Hermes terminal sessions.
Winner: Hermes WebUI.

Hermes WebUI: dark/light. Limited theming.
Open WebUI: themes marketplace. Highly customisable.
Winner: Open WebUI.
Round 10 — Community
Hermes WebUI: smaller, Hermes-focused community.
Open WebUI: large general AI community. Many plugins.
Winner: Open WebUI.
Final Tally
Hermes WebUI: 4 wins Open WebUI: 4 wins Ties: 2
A draw on aggregate. The right choice depends on your context.

My Setup — Hermes WebUI Primary
I run Hermes WebUI as primary because:
- 80% of my agent work is Hermes
- The Hermes-specific features matter to my workflow
- Skills, memory, profiles are key
I keep Open WebUI installed for:
- Multi-agent comparisons
- Testing new agents (Claude Code, OpenClaw)
- Plugin experiments
Both run on different ports. No conflict.
When To Switch Primary
If you start running 3+ AI agents seriously, switch primary to Open WebUI.
The single-pane-of-glass for all agents matters more than Hermes-specific polish.
If you stay Hermes-only, stick with Hermes WebUI.
For multi-agent setup patterns, my hermes deepseek post covers the cross-agent flow.
