Most setup guides skip the gotchas.

This one walks every step in the right order, including:

Pre-checks
Install command
Provider config
First chat verification
Common errors and fixes

By the end you'll have Hermes WebUI running on localhost with a working chat session.

What You'll Have After

Hermes WebUI running on http://localhost:8080
Connected to your existing Hermes terminal config
At least one model provider working
A first successful chat
Confidence the stack is solid

Prerequisites

Before starting:

Hermes terminal already installed (my hermes ai course post covers the base install)
Node.js 18+ and npm
Git
At least one model API key

Skip these and the setup fails. Verify each.

Step 1 — Get The Quick-Start Command (30 seconds)

Two paths:

Path A: Ask Hermes terminal.

Open Hermes terminal. Type:

"Install Hermes WebUI for me."

Hermes runs the install commands. Easiest path.

Path B: Run manually.

Visit the Hermes WebUI GitHub. Copy the quick-start command. Run it.

Both work. Path A handles errors more gracefully.

Step 2 — Run The Install (2-3 minutes)

For Path B, the command looks like:

git clone https://github.com/hermes-ai/hermes-webui.git
cd hermes-webui
npm install

Wait for npm install to complete. Usually 60-180 seconds.

For Docker users:

docker run -p 8080:8080 hermes/webui:latest

One-shot, but harder to customise.

Step 3 — Update Hermes (30 seconds)

WebUI requires Hermes terminal v0.11+.

Check version:

hermes --version

If lower than 0.11:

hermes update

Updates take 30-60 seconds.

Step 4 — Start Hermes WebUI (10 seconds)

cd hermes-webui
npm start

Output shows:

Hermes WebUI running at http://localhost:8080

Open that URL in your browser.

WebUI loads. Sidebar visible. Chat empty.

Step 5 — Configure Provider (1 minute)

Click Settings.

Click API Keys.

Add at least one:

Anthropic: paste Claude API key
OpenRouter: paste OpenRouter key
Ollama: point at http://localhost:11434 (no key needed)

Save.

Now go back to chat. Provider dropdown shows the configured options.

For provider-specific patterns, my hermes deepseek post covers the model layer.

Step 6 — Hermes WebUI First Chat Test (30 seconds)

Pick a provider from dropdown.

Pick a model.

Type:

"Are you working? What model are you running?"

Hermes responds with model name and confirms online.

Setup verified.

If the response is empty or errored, check:

Provider key is correct
Model name matches exactly
Internet connection
Hermes terminal is running

For diagnostic patterns, my build your own openclaw post covers the troubleshooting tree.

Step 7 — Configure Profile (Optional, 2 minutes)

Click Profiles in sidebar.

If you have profiles configured in terminal Hermes, they appear automatically.

If not, click "+ New Profile":

Name
Persona
Skills (multi-select)
Default model

Save.

Switching profile in chat now uses that config.

Step 8 — Skills + Memory (Optional, 5 minutes)

Skills tab shows everything available.

Browse installed skills
Install new from community library
Edit skill prompts inline

Memory tab shows facts stored:

Add new ones
Edit stale ones
Delete obsolete

These changes apply to the next chat message.

Common Setup Issues

Port 8080 already in use. Change the port in WebUI config or kill the conflicting process.

WebUI won't connect to Hermes. Make sure Hermes terminal is running. Check the URL in WebUI settings matches Hermes daemon address.

Provider keys rejected. Re-copy from source — sometimes invisible chars get pasted.

Models dropdown empty. Provider config saved but model list not refreshed. Logout/login or restart WebUI.

Mobile access fails. Local network only by default. For remote access, you need Cloudflare Tunnel or VPS.

For more diagnostics, my hermes ai course post covers the Hermes log inspection pattern.

Maintenance

Update WebUI weekly. Active project, frequent improvements.

Backup Hermes config monthly. Export from settings.

Test all providers quarterly. API keys can rotate. Models can deprecate.

Review skills quarterly. Some get superseded. Prune.

Production Considerations

For personal use on a Mac, the localhost setup is fine.

For team/agency use:

Run on a VPS (£5-10/month)
Configure HTTPS via Caddy or Cloudflare Tunnel
Add basic auth or OAuth
Monitor uptime
Backup nightly

For more on production hardening, my deepseek openclaw post covers the patterns.
