Claude Code is powerful. But running it at scale in production requires more than just an API key. You need routing, control, visibility, cost tracking.

That's where Bifrost comes in.

Bifrost is a high-performance, Go-based gateway that transforms Claude Code from a developer tool into an enterprise-ready system. Combined with Bifrost CLI, it's the cleanest, fastest way to deploy Claude Code in production.

Let me show you why.

👀 Why You Need a Gateway for Claude Code

Claude Code works great locally. But in production, you face real problems:

No cost visibility — Who's using Claude Code? How much is it costing?
No access control — Everyone has access to everything
No rate limiting — A runaway workflow can spike costs $1,000+ in minutes
No audit trail — You can't prove compliance or debug failures
No model switching — Locked into one provider, one model
No failover — If one provider goes down, everything stops

Bifrost solves all of this.

⚙️ 1. Bifrost: Enterprise Control for Claude Code

What Bifrost Does

Bifrost is a lightweight, Go-based gateway that sits between Claude Code and your Claude API:

Claude Code → Bifrost Gateway → Claude API

💎 Star Bifrost ☆

Everything that makes Claude Code powerful stays intact. But now you get:

Control

Route Claude Code through a single gateway
Control which teams access what
Rate limit by user, team, or role
Enforce budgets and cost limits

Visibility

Track every Claude Code request
Know exactly what's costing money
Identify usage patterns
Audit all agent activity

Reliability

Automatic failover between providers
Load balance across API keys
Semantic caching
100% success rate at 5,000+ RPS

Security

Role-based access control (RBAC)
Secure key storage (OS keyring)
No plaintext credentials anywhere
Complete audit logs for compliance

Performance: 40x Faster Than Alternatives

Bifrost is written in Go, compiled into a single binary:

Gateway Overhead:     11 µs (vs 440 µs for another gateways)
Memory Usage:        -68% (compared to alternatives)
Queue Wait Time:    1.67 µs (vs 47 µs)
Success Rate @ 5k RPS: 100% (vs 89%)
Total Latency:     1.61 s (24% faster than others)

Why? Go's goroutines (lightweight concurrency), compiled binary (no runtime), and memory efficiency. It's the difference between adding milliseconds of overhead vs microseconds.

Easy Setup

# Start Bifrost gateway
npx -y @maximhq/bifrost -p 8000

# Opens http://localhost:8000
# Web UI for configuration

That's it. No complex setup. No Docker required (though available).

🔎 2. Bifrost CLI: Best CLI for Claude Code

Here's the problem with Claude Code in production:

# Every developer does this:
export ANTHROPIC_API_KEY="sk-..."
export CLAUDE_BASE_URL="https://api.anthropic.com"
claude

It's manual, error-prone, and doesn't scale.

Bifrost CLI solves this completely.

What Bifrost CLI Does

npx -y @maximhq/bifrost-cli -p 8000

That's all you need. The CLI:

✅ Detects your Bifrost gateway automatically

✅ Fetches available Claude models from Bifrost

✅ Configures API keys and base URLs automatically

✅ Installs Claude Code if needed

✅ Attaches MCP servers for tool access

✅ Stores credentials securely in OS keyring

✅ Launches Claude Code ready to work

Interactive Setup (30 seconds)

1. Base URL → http://localhost:8000
2. Virtual Key (optional) → your-key-or-skip
3. Choose Agent → Claude Code
4. Select Model → anthropic/claude-opus-4-5
5. Press Enter → Claude Code launches

Everything is configured. No config files. No manual setup.

Persistent Sessions & Model Switching

The CLI launches Claude Code in a tabbed terminal UI:

Ctrl+B — Open tab bar
n — New Claude Code session
m — Switch to different Claude model
x — Close current session
1-9 — Jump to tab

Want to switch from Claude 3.5 Sonnet to Claude Opus? Just press m and pick a different model. Everything reconfigures automatically.

Keyboard Shortcuts

Enter — Launch Claude Code
m — Change Claude model
h — Switch to different agent (Claude Code, Codex, Gemini)
d — Open Bifrost dashboard
r — Open documentation
q — Quit

Configuration Saved Automatically

{
  "base_url": "http://localhost:8000",
  "default_harness": "claude",
  "default_model": "anthropic/claude-opus-4-5-20250929"
}

Next time you run bifrost, your previous configuration is ready. Just press Enter.

⚙️ 3. Control: Role-Based Access

Different teams need different access levels:

roleToToolsMapping := map[string][]string{
    "engineering": {"filesystem", "database", "github-api"},
    "research":    {"web-search", "documents"},
    "finance":     {"reports", "cost-tracking"},
    "admin":       {"*"},  // All access
}

roleLimits := map[string]map[string]int{
    "engineering": {"database": 500},      // 500 requests/min
    "research":    {"web-search": 100},    // 100 searches/min
    "finance":     {"reports": 50},        // 50 reports/min
}

An engineer tries to run a database query — allowed. Finance tries to delete data — denied. Marketing tries to access source code — blocked.

Real example:

# Engineering user
curl -X POST http://localhost:8000/v1/messages \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-3-5-sonnet",
    "messages": [...],
    "user_role": "engineering"
  }'
# ✅ Success

# Finance user trying to access engineering tools (denied)
curl -X POST http://localhost:8000/v1/messages \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-3-5-sonnet",
    "messages": [...],
    "user_role": "finance"
  }'
# ❌ 403 Forbidden

Rate Limiting Prevents Cost Spikes

One AI workflow got stuck in a loop and made 1,000 requests in 5 minutes. Cost spike: $2,000.

With Bifrost rate limiting:

Request 1: ✅ OK (99/100 remaining)
Request 50: ✅ OK (50/100 remaining)
Request 100: ✅ OK (limit reached)
Request 101: ❌ Rate limited (retry after 45s)

The runaway workflow is caught immediately. Cost: ~$0.10 instead of $2,000.

4. 💻 Visibility: Cost Tracking & Audit Logs

Know Exactly What You're Spending

GET /v1/analytics/costs?team_id=team-engineering&period=month

{
  "total_cost": "$1,234.56",
  "budget": "$5,000.00",
  "remaining": "$3,765.44",
  "usage_by_user": [
    {"user_id": "engineer-1", "cost": "$456.78"},
    {"user_id": "engineer-2", "cost": "$234.56"}
  ]
}

Every Claude Code request is logged with:

Who ran it
What team they're on
How long it took
How much it cost
Whether it succeeded

Audit Everything

{
  "user_id": "engineer-001",
  "user_role": "engineering",
  "model": "claude-3-5-sonnet",
  "cost": "$0.45",
  "duration_ms": 1234,
  "success": true
}

For compliance audits: "Here's every Claude Code request from January." Done.

For debugging: "That model died at 2:15 PM." You have the exact request, model, input, output, and error.

📦 5. Reliability: Failover & Caching

Automatic Failover

If one API key hits rate limits or one provider goes down:

Claude Code request → Primary key fails → 
Automatically retry with secondary key → Success

No downtime. Transparent to Claude Code.

Semantic Caching

Claude Code asks: "Summarize this file"

First request: API call → $0.10
Second request (same file, different wording): Cached result → $0.00

Bifrost uses vector similarity to match requests semantically, not by exact string match.

Bifrost CLI + Codex CLI: One Command to Set Up OpenAI's Coding Agent with Any Model

Anthony Max — Thu, 19 Mar 2026 18:00:26 +0000

Tired of manually configuring API keys, and provider paths every time you launch a coding agent? Bifrost CLI solves this with a single command.

Launch Codex CLI (or Claude Code, Opencode) through your Bifrost gateway with no configuration. The CLI handles everything automatically: base URLs, API keys, model selection, and MCP integration.

👀 1. What is Bifrost CLI?

Bifrost CLI is an interactive terminal tool that connects your favorite coding agents to your Bifrost gateway. Instead of environment variables and config files, you just run a command and pick your agent, model, and go.

npx -y @maximhq/bifrost-cli

What it does for you:

✅ Automatically configures base URLs, API keys, and model settings
✅ Fetches available models from your Bifrost gateway
✅ Installs missing agents via npm if needed
✅ Auto-attaches Bifrost's MCP server for tool access
✅ Launches agents in a tabbed terminal UI
✅ Stores your selections securely in OS keyring

Supported agents:

Claude Code (with MCP auto-attach)
Codex CLI (OpenAI's coding agent)
Gemini CLI (Google's agent)
Opencode (Custom models support)

💎 Star Bifrost ☆

⚙️ 2. Getting Started in 3 Easy Steps

It takes only 5 minutes to use the CLI.

Step 1: Start Bifrost Gateway

Make sure your Bifrost gateway is running:

npx -y @maximhq/bifrost -p 8000
# Gateway starts at http://localhost:8000

Step 2: Launch Bifrost CLI

In another terminal:

npx -y @maximhq/bifrost-cli

Step 3: Follow the Interactive Setup

The CLI guides you through:

Base URL — Enter your Bifrost gateway URL
Virtual Key (optional) — If you have authentication enabled
Choose Agent — Pick Codex, Claude Code, Gemini, or Opencode
Select Model — Searchable list of available models from your gateway
Review & Launch — Press Enter to start

That's it. Your agent launches with everything configured automatically.

🔎 3. How It Works: Configuration Magic

Bifrost CLI stores configuration automatically:

{
  "base_url": "http://localhost:8000",
  "default_harness": "codex",
  "default_model": "openai/gpt-4o"
}

The magic:

Base URL and API keys are fetched from your Bifrost gateway
Your Codex CLI gets the correct provider path (/openai)
Model selection happens from available models in the gateway
Virtual keys are stored securely in OS keyring (never plaintext)

Switch agents anytime:

Press Ctrl+B to open the tab bar. Then:

h — Switch to different agent (Claude Code, Codex, Gemini, Opencode)
m — Pick different model
Enter — Launch

and more.

No environment variables. No config editing. Just shortcuts.

🔗 4. Tabbed Sessions & MCP Integration

After launch, you stay in a persistent tabbed terminal UI. Switch between sessions without re-running the CLI:

Ctrl+B — Open tab bar
n — New session
x — Close current tab
h/l — Navigate tabs
1-9 — Jump to specific tab

Status badges:

Agent is working
Session idle and ready
Terminal alert

For Codex CLI specifically:

MCP server auto-configured for Bifrost
Access to all your configured tools through the gateway
Automatic provider path routing (/openai)

The session flow is seamless:

Launch → Work → Switch Sessions → Return → Re-launch

Your last selections are remembered. Next time you run bifrost, you'll see the summary screen with your previous configuration ready.

✅ 5. Advanced Features

Custom config path:

npx -y @maximhq/bifrost-cli -config ./my-project/bifrost.json

Useful for multiple Bifrost gateways or project-specific setups.

Available flags:

-config <path>    # Custom config file location
-no-resume        # Skip resume flow, start fresh setup
-worktree <name>  # Create git worktree (Claude Code only)

Keyboard shortcuts during setup:

Enter — Launch with current settings
r — Open documentation
l — Toggle harness exit logs

and more.

Example: Launch with custom worktree

npx -y @maximhq/bifrost-cli -worktree feature-branch

This launches Claude Code in an isolated git worktree for parallel development.

📦 Installation & Requirements

Bifrost CLI requires:

Node.js 18+ (for npx)
A running Bifrost gateway

# First time
npx -y @maximhq/bifrost-cli

# If installed, just run
bifrost

💻 Results

Before Bifrost CLI:

❌ Set OPENAI_API_KEY manually
❌ Edit config files with provider paths

✅ Persistent tabbed sessions

For Codex CLI users, this means instant access to OpenAI's powerful coding agent with Bifrost's routing, control, and MCP tools — all from one command.

🔎 Quick Reference

# Start Bifrost gateway
npx -y @maximhq/bifrost

# Launch CLI (in another terminal)
npx -y @maximhq/bifrost-cli

# Follow interactive setup
# Select: Codex CLI → Model → Launch

# Once running, use Ctrl+B to switch sessions

🖋 Conclusion

Bifrost CLI eliminates the friction of coding agent setup no more config files, or manual key management. One command
(npx -y @maximhq/bifrost-cli) launches your agent with everything automatically
configured and secure. Stop configuring, start building.
