rflectr

Relay any model into any coding agent.

Launch your tools, switch providers mid-session, and run local API gateways — all from one CLI.

npm install -g @legioncodeinc/rflectr

What is rflectr?

rflectr is an interactive CLI that launches AI coding tools and runs local API gateways on your machine — so you can point any coding agent at any model provider.

It currently supports Claude Code, Claude Desktop (Cowork + Code), the OpenAI Codex CLI, the Codex desktop app, and the Google Gemini CLI.

Features

🗂️ Providers & models

• Native provider registry — rflectr providers stores config in ~/.rflectr/providers.json and secrets in the OS keychain. No OpenCode binary required at launch. See the Providers guide for the full list and known issues.
• Provider templates — Add Groq, Mistral, Together, OpenRouter, and 15+ SDK-backed providers, plus custom OpenAI/Anthropic-compatible endpoints.
• OpenCode import — One-time migration from OpenCode (providers import); validates API keys and skips placeholders like anything.
• OpenCode Zen / Go — Optional cloud backends when you have an OpenCode API key.
• Favorite models — Save up to 20 and switch mid-session with Claude Code's /model command.
• Smart model pickers — Recent models per provider, search for large lists (>25), paginated browse (15 per page).
• Refresh model lists — rflectr providers refresh-models updates cached catalogs per provider.

🛰️ Gateways & routing

• SDK adapter proxy — Non-Anthropic providers route through the Vercel AI SDK (same packages OpenCode uses), so Claude Code still speaks Anthropic format. Labeled via proxy in the picker.
• API server — Run a local gateway on port 17645 for Claude Code, Claude Desktop, or any Anthropic-compatible client.
• Server wizard — Filter exposed providers, mask discovery ids for Claude Desktop, optional favorites-only catalog, local vs network listen mode.
• Vertex gateway — Anthropic-compatible Claude on Google Vertex AI using gcloud Application Default Credentials.

🔒 Safety & ergonomics

• Clean environment isolation — We strip 17 conflicting env vars (Vertex AI, Bedrock, AWS, Foundry, stale Anthropic config) from the child process only. We never touch ~/.claude/settings.json (see caveat below).
• Secure key storage — Per-provider keys and the OpenCode API key go in the OS credential store (macOS Keychain, Windows Credential Manager, Linux Secret Service) or your shell profile.
• Cross-platform — macOS, Windows, Linux (Ubuntu, Fedora, distros with GNOME Keyring or KWallet).
• Dry run mode — Walk through the full wizard and preview the launch command without starting anything.
• Preference memory — Last provider and model are pre-selected next time.
• Agent / headless launch — Boot flags (--provider, --model), clean NDJSON/JSONL stdout for alef-agent, and rflectr --ai reference. See the AI Agents guide.

Prerequisites

| Requirement | Needed for | |---|---| | Node.js 18+ | Everything | | A supported AI coding tool installed | Launching that tool — Claude Code, OpenAI Codex, or Google Gemini CLI | | At least one provider | Configure via rflectr providers add / import, or an OpenCode API key for Zen/Go cloud backends | | OpenCode CLI (optional) | One-time import from an existing OpenCode setup | | Google Cloud SDK (Vertex only) | gcloud auth application-default login, a GCP project with Vertex AI enabled, and Claude partner models enabled |

[!NOTE] On providers: rflectr keeps your provider list in ~/.rflectr/providers.json. You can add providers directly (API key + template), import from OpenCode once, or use Zen/Go cloud backends. OpenCode is not required after setup.

Installation

Install the CLI globally:

npm install -g @legioncodeinc/rflectr

Upgrade to the latest version:

npm update -g @legioncodeinc/rflectr

Uninstall:

npm uninstall -g @legioncodeinc/rflectr

[!NOTE] If you use a Node version manager like NVM, run the uninstall command using the active Node version that was used to install it (e.g., run nvm use <version> first).

Remove all configuration data by deleting the .rflectr directory:

| Platform | Command | |---|---| | 🍎 macOS / 🐧 Linux | rm -rf ~/.rflectr | | 🪟 Windows (cmd) | rmdir /s /q "%USERPROFILE%\.rflectr" | | 🪟 Windows (PowerShell) | Remove-Item -Recurse -Force "$env:USERPROFILE\.rflectr" |

Setup

1. Configure providers

rflectr providers          # hub: add, import, list, refresh models
rflectr providers add      # pick a template or custom endpoint
rflectr providers import   # one-time migration from OpenCode (optional)

On first rflectr claude run with an empty registry, an inline wizard walks you through Quick start (Zen), import, or opening rflectr providers.

2. OpenCode API key (Zen/Go only)

Grab your key at opencode.ai/auth if you use OpenCode Zen or Go (skip for registry-only or Vertex setups).

| Platform | 🔐 Secure storage | 📄 Plaintext fallback | |----------|---------------|-------------------| | 🍎 macOS | Keychain (optional: + ~/.zshrc auto-load) | Shell profile | | 🪟 Windows | Credential Manager | setx user env var | | 🐧 Linux (desktop) | Secret Service (GNOME Keyring / KWallet) | Shell profile | | 🐧 Linux (headless) | n/a | Shell profile |

[!TIP] The key is active in your current session right away, no matter which option you pick. No terminal restart needed.

Usage

Launch Claude Code

rflectr claude

First run: pick a provider from your registry (or complete the inline setup wizard). If you've added OpenCode Zen/Go, those appear alongside registry providers like Groq, Nvidia, or DeepSeek.

Favorite models and mid-session switching

Save the models you bounce between:

rflectr models

Add up to 20 favorites from Zen, Go, or any OpenCode-configured provider. When you have favorites, rflectr claude starts a multi-route proxy automatically. Claude Code's /model command lists your starting model plus favorites. Switch live, no restart.

No favorites? Launch works like before: single model, no switch menu. --dry-run ignores saved favorites so you can preview a single-model launch.

rflectr claude options

| Flag | Description | |------|-------------| | --dry-run | Run the full wizard but preview the launch command instead of executing | | --setup | Reminder to use rflectr providers for provider setup | | --trace | Write debug logs to ~/.rflectr/logs/ and show errors on exit | | --help | Show command help | | --version | Show version |

rflectr claude --dry-run
rflectr claude --setup
rflectr claude --trace

Claude Code flags and session IDs pass through unchanged:

rflectr claude -c
rflectr claude --resume abc-123
rflectr claude abc-123

Non-interactive / agent launch — skip the wizard with boot flags:

rflectr claude --provider groq --model llama-3.3-70b-versatile -p "Summarize README.md"
rflectr claude --model zen__deepseek-v4-flash-free -p "task" --output-format stream-json

| Flag | Description | |------|-------------| | --provider | Boot provider id (skip wizard with --model or in print mode) | | --model | Boot model id, or slug provider__model-id |

For alef-agent, NDJSON streaming, Codex exec --json, and sandbox defaults, see the AI Agents guide and run rflectr --ai.

Use -- when you want every following token passed directly to Claude Code:

rflectr claude -- --print "hello"
rflectr claude -- --dangerously-skip-permissions
rflectr claude --dry-run -- --print "test"

Server mode

Run rflectr as a foreground API gateway on port 17645:

| Mode | Command | Auth | Models | |------|---------|------|--------| | Registry gateway | rflectr server | Per-provider keys in registry (+ OpenCode key for Zen/Go if exposed) | Providers you configured | | Vertex gateway | rflectr server --vertex | gcloud Application Default Credentials | Claude on Vertex AI |

[!TIP] Claude Desktop (Cowork + Code): For the automated macOS/Windows setup, use rflectr claude-app. For manual or network setups, see the Claude Desktop guide.

Registry gateway (rflectr server)

Works with any providers in your registry. Zen/Go models appear when you have an OpenCode API key and those providers are exposed.

The wizard asks:

| Prompt | What it does | |--------|--------------| | Configure & start vs Start with saved settings | Full wizard or reuse saved server preferences | | Exposed providers | Limit which providers appear in the catalog (Zen, Go, Groq, OpenAI, etc.) | | Mask gateway model ids for discovery? | Recommended Yes for Claude Desktop — hides competitor vendor strings in model ids so discovery works | | Expose only favorite models? | Optional cap at your favorites (manage with rflectr models) | | Listen mode | Local only (127.0.0.1) or Network (0.0.0.0 + server password) |

Local mode — point any Anthropic-compatible client at your machine:

export ANTHROPIC_BASE_URL="http://127.0.0.1:17645/anthropic"
export ANTHROPIC_API_KEY="anything"

Network mode — other devices on your LAN:

export ANTHROPIC_BASE_URL="http://<server-ip>:17645/anthropic"
export ANTHROPIC_API_KEY="<server-password>"

By default the server password stays in memory only. If you choose to save it, rflectr stores it in ~/.rflectr/config.json.

OpenAI-format models also get an OpenAI-compatible endpoint:

export OPENAI_BASE_URL="http://127.0.0.1:17645/openai/v1"
export OPENAI_API_KEY="anything"

Health check:

curl -s http://127.0.0.1:17645/health
curl -s http://127.0.0.1:17645/anthropic/v1/models | head

The spinner reports how many models loaded and how many came from registry providers.

Vertex gateway (rflectr server --vertex)

Anthropic-compatible gateway to Claude on Google Vertex AI. No OpenCode API key required.

Setup:

gcloud auth application-default login
export ANTHROPIC_VERTEX_PROJECT_ID="your-gcp-project"   # or GOOGLE_CLOUD_PROJECT
export GOOGLE_CLOUD_LOCATION="global"                   # optional; default: global
rflectr server --vertex

• Default models: claude-sonnet-4-6, claude-opus-4-6, claude-haiku-4-5
• Shorthand aliases (for Claude Code /model and settings.json): sonnet, opus, haiku. Append [1m] for 1M context on Sonnet and Opus only (Haiku stays 200k).
• Custom catalog: copy assets/vertex-models.example.json to ~/.rflectr/vertex-models.json and edit. Override the config directory with RFLECTR_HOME.

When the gateway is running:

export ANTHROPIC_BASE_URL="http://127.0.0.1:17645/anthropic"
export ANTHROPIC_API_KEY="anything"

[!TIP] Claude Code tip: When routing through the gateway, unset native Vertex env vars so Claude Code doesn't bypass the proxy:

unset CLAUDE_CODE_USE_VERTEX ANTHROPIC_VERTEX_PROJECT_ID CLOUD_ML_REGION

Codex CLI (rflectr codex)

Launch OpenAI Codex CLI with registry providers. Requires npm install -g @openai/codex.

rflectr providers add    # Anthropic, xAI, OpenAI, etc.
rflectr codex            # pick provider + model → Codex TUI

rflectr writes a temporary profile (~/.codex/rflectr-launch.config.toml) and removes it when Codex exits. After a crash: rflectr codex --restore.

Sandbox / network: rflectr codex defaults to danger-full-access (profile + -s flag) so shell tools like curl, nlm, and npm can reach the network. Override for one session:

rflectr codex -s workspace-write

Pass Codex flags directly after rflectr codex — you do not need -- before -s. Codex's --dangerously-bypass-approvals-and-sandbox also passes through if you need it.

Full details: Codex guide — CLI + desktop app, configs, restore, sandbox, routing. For agent / alef-agent integration (boot flags, NDJSON, JSONL): AI Agents guide and rflectr --ai.

Claude Desktop app (rflectr claude-app)

Launch Claude Desktop (macOS or Windows) with registry providers:

rflectr claude-app

This command automates the "Third-Party Inference" (Developer Mode) setup. It temporarily configures Claude Desktop to point at a local gateway, launches the app, and routes traffic to your chosen provider.

• Keep the terminal open — The proxy runs in the foreground.
• Ctrl+C to restore — When you're done, press Ctrl+C in the terminal to automatically restore Claude Desktop to its normal Anthropic cloud mode.
• Cleanup — If the terminal crashes, run rflectr claude-app --restore.

For manual network setups (e.g., remote cloud desktop), you can still use rflectr server. See the full Claude Desktop Setup Guide.

Codex desktop app (rflectr codex-app)

Launch the Codex app (macOS or Windows) with registry providers:

rflectr codex-app

Patches ~/.codex/config.toml with backup; Ctrl+C in the rflectr terminal restores your config. The app keeps Codex's built-in openai provider active so existing conversation history remains visible, and routes the selected model through a foreground local proxy. Preview config without writing: rflectr codex-app --config. Recovery: rflectr codex-app --restore.

See the Codex guide for CLI vs app differences, file ownership, and troubleshooting.

[!TIP] Reasoning effort: Capable models show Codex's native reasoning picker (low/medium/high, etc.). rflectr maps your choice to each provider's SDK options and preserves existing model_reasoning_effort in Codex config. Claude Code /effort and the rflectr server gateway use the same mapping — see the reasoning section in the Codex guide.

Google Gemini CLI (rflectr gemini)

Launch the Google Gemini CLI with registry providers.

rflectr gemini

Pick provider → pick model → Gemini prompt loop opens. Non-interactive tasks with streaming NDJSON are also fully supported:

rflectr gemini --provider google --model gemini-2.5-flash -p "Review this file" -o stream-json

For agent / alef-agent integration (boot flags, NDJSON): AI Agents guide and rflectr --ai.

How it works

OpenCode Zen / Go filtering

When OpenCode Zen is in your registry, subscriptionFilter controls which Zen models appear (free = free tier only; default = all Zen models). Add or change Zen via rflectr providers.

Environment isolation

When you launch, rflectr builds a clean child environment:

1. Removes 17 conflicting env vars from the child process (Vertex AI, Bedrock, AWS, Foundry, stale Anthropic config)
2. Sets ANTHROPIC_BASE_URL, ANTHROPIC_API_KEY, and ANTHROPIC_MODEL for the session
3. Passes --model <selected> to Claude Code as a backup override

When Claude Code exits (normal exit, Ctrl+C, terminal close), your shell is unchanged. No cleanup step. No restore needed.

[!WARNING] Claude Code persists the model. rflectr doesn't edit ~/.claude/settings.json, but Claude Code saves the model you launched with (via --model and ANTHROPIC_MODEL). A later bare claude launch may still show that model, e.g. anthropic-opencode-go__deepseek-v4-flash from a prior rflectr session. To get back to a first-party default, run claude --model sonnet (or your preferred Claude model), or remove the "model" key from ~/.claude/settings.json. If you used the favorites switch menu, Claude Code may also cache the gateway catalog at ~/.claude/cache/gateway-models.json. Delete that file if /model shows stale entries from a dead proxy.

Model compatibility

OpenCode exposes models through different API formats. rflectr handles them when it can:

| Model format | Examples | How it works | Label | |---|---|---|---| | Anthropic native | Claude, Qwen, MiniMax (Go) | Direct connection | (none) | | OpenAI chat completions | DeepSeek, Kimi, MiMo, GLM, Grok, GPT-4o | SDK adapter proxy (Vercel AI SDK) | via proxy | | OpenAI Responses API | GPT-5.4+, GPT-5.5, Codex, o-series | Same proxy; SDK picks Responses API | via proxy | | Gemini native | Gemini (OpenCode Google provider) | SDK adapter, Gemini native API | via proxy | | Other SDK providers | Cerebras, Perplexity, Bedrock, Vertex, Together AI | Whatever api.npm OpenCode assigns | via proxy | | Not in cloud wizard | GPT, Gemini on OpenCode Zen/Go | Use an OpenCode-configured provider instead | not yet supported |

The SDK adapter proxy starts on a random local port for proxy-routed models and stops when Claude Code exits. Each rflectr claude session gets its own port, so multiple terminals are fine. (rflectr server uses fixed port 17645 — one server instance per machine.)

Provider notes

[!NOTE] Mistral (free tier): Rate limits are tight. Expect HTTP 429 during tool-heavy sessions. Claude Code retries with backoff. That's Mistral throttling, not a proxy bug.

[!NOTE] OpenAI (OpenCode-configured provider): Configure OpenAI in OpenCode with your API key, then pick the OpenAI provider at launch. Newer GPT models use OpenAI's Responses API. The SDK picks responses vs chat from the model ID. OpenCode catalog IDs can differ from API IDs (e.g. gpt-5.5-fast maps to upstream gpt-5.5). If you see "model not available", run rflectr claude --trace and check ~/.rflectr/logs/claude-debug.log.

CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS=1 is set for direct (non-proxy) routes only. Proxy sessions keep tool-search betas.

API key storage

rflectr uses @napi-rs/keyring for the OS credential store. On later runs it checks silently. Key found? Wizard skips the prompt.

| Platform | Credential store | Notes | |----------|-----------------|-------| | 🍎 macOS | macOS Keychain | Optional ~/.zshrc auto-load line for system-wide availability | | 🪟 Windows | Windows Credential Manager | setx available as plaintext alternative | | 🐧 Linux (desktop) | Secret Service API (GNOME Keyring, KWallet) | Needs a running keyring daemon | | 🐧 Linux (headless) | Not available | Falls back to shell profile or session-only |

If the native module fails to load, credential store options are skipped and you get shell profile / session-only storage.

Configuration

Provider registry (no secrets in this file):

~/.rflectr/providers.json

Manage with rflectr providers. API keys are stored in the OS keychain (keyring:provider:<id>).

App preferences — favorites, last provider/model, server settings, optional server password:

~/.rflectr/config.json

Override the config directory:

export RFLECTR_HOME="/path/to/your/rflectr-home"

The OpenCode API key (for Zen/Go) and per-provider keys are stored separately, based on what you chose during setup (Keychain, credential store, or shell profile).

Troubleshooting

See the Troubleshooting guide for common issues — especially "Not logged in" after accidentally choosing No on Claude Code's custom API key prompt.

If you used the old opencode-starter CLI, rflectr migrates automatically on first run:

• Config moves from ~/.opencode-starter/ → ~/.rflectr/
• Legacy Keychain / credential-store entries are read and re-saved under rflectr
• The CLI command is now rflectr (not opencode-starter)
• Launch Claude Code with rflectr claude (bare rflectr prints help)

The deprecated OPENCODE_STARTER_HOME env var still works as a fallback for RFLECTR_HOME.
