What You Get

• 49 ToS-friendly providers. 1.3B+ free tokens every month. Use free, paid, subscription, and local models from one searchable UI without putting your account at risk. FCC follows provider terms and removes integrations if they stop being allowed.
• 9 coding agents. One model catalog. Run Claude Code, Codex, Pi, OpenCode, Cline, Hermes, DeepSeek Harness, Grok Build, or Muse Code with your FCC models.
• Keep coding through provider outages. After retries are exhausted, FCC automatically tries your next configured model without making you restart the turn—across every client.
• Up to 90% fewer terminal-output tokens. Optional RTK filters common command output, while five FCC optimizations handle quota probes, command-prefix detection, titles, suggestions, and filepaths without calling a provider.
• Terminal, desktop, IDE, or phone. Work through native launchers, VS Code, Codex App, JetBrains, Discord, or Telegram.
• Voice notes in. Code out. Talk to your agent using local Whisper or NVIDIA NIM transcription.
• Agent capabilities stay intact. Stream responses, use tools, preserve native interleaved thinking for maximum performance, send images, and route Fable, Opus, Sonnet, and Haiku independently with compatible models.

Free-tier availability and limits are controlled by each provider and may change.

Claude Code running with FCC.

Quick Start

1. Install Or Update

macOS/Linux:

curl -fsSL "https://raw.githubusercontent.com/Alishahryar1/free-claude-code/main/scripts/install.sh" | sh

Windows PowerShell:

& ([scriptblock]::Create((irm "https://raw.githubusercontent.com/Alishahryar1/free-claude-code/main/scripts/install.ps1")))

Re-run the same command to update. When prompted, choose at least one coding agent and optionally RTK. You can review the installers before running them: install.sh and install.ps1.

2. Start FCC

Windows

Open Free Claude Code from your desktop or Start menu.

macOS

Open Free Claude Code from your desktop or Applications folder.

Linux

Run:

fcc-server

FCC opens the Admin UI after starting. On Windows and macOS, use the tray or menu-bar icon to open Admin, restart, or quit. When using fcc-server, keep its terminal open.

3. Configure NVIDIA NIM

1. Create an API key at build.nvidia.com/settings/api-keys.
2. Open the Admin UI URL from the server log.
3. Paste the key into NVIDIA_NIM_API_KEY.
4. Leave MODEL on the default nvidia_nim/nvidia/nemotron-3-super-120b-a12b, or search the model dropdown and select another model.
5. Click Validate, then Apply.

To protect the local proxy with a bearer token, enable Proxy Authentication in Admin.

4. Run Your Coding Agent

Claude Code:

fcc-claude

Codex:

fcc-codex

Pi:

fcc-pi

OpenCode:

fcc-opencode

Cline:

fcc-cline

Hermes:

fcc-hermes

DeepSeek Harness Web:

fcc-dsh

DeepSeek Harness headless:

fcc-dsh --profile headless "your task"

Grok Build:

fcc-grok

Muse Code:

fcc-muse

All nine launchers use the current Admin UI settings. Use the agent's model picker to choose from the models FCC exposes. Normal CLI arguments still work, for example:

fcc-codex exec "hello"

FCC launchers leave your existing agent settings, sessions, credentials, and extensions unchanged. fcc-hermes starts attached sessions through FCC; choosing another provider with Hermes /model intentionally leaves the FCC route. fcc-dsh keeps DeepSeek Harness sessions and plugins while applying temporary FCC provider settings. It currently supports the preview release 0.1.0-rc.8 on Node.js ^22.19 or >=24. fcc-grok keeps Grok Build's sessions and plugins, while routing attached sessions through FCC. Web search and fetch stay disabled until FCC supports Grok Build's Responses-side web-tool contract. fcc-muse keeps Muse Code's native sessions and settings while routing attached sessions through FCC. Muse is beta; Meta's official installer currently supports macOS, Linux, and WSL, while Windows requires a compatible preinstalled binary.

Select an FCC model from Claude Code's native /model picker.

Choose A Provider

1. Open a provider link below for its key, models, or setup instructions.
2. In the Admin UI, configure the listed setting. For OpenAI, use Providers → Connected accounts instead.
3. Search the MODEL dropdown and select a model. If the provider cannot list models, enter <provider-id>/<exact-provider-model-id> manually.
4. Click Validate, then Apply.

Optional: add an ordered Fallback Models list under Model Config. It applies to every connected client. A failed request may reach and consume usage from more than one provider before succeeding.

Provider-specific setup

• OpenAI uses your ChatGPT subscription rather than an API key. Connect from Providers → Connected accounts in the Admin UI. Use device code on headless systems. Restart an already-running agent after connecting.
• Azure OpenAI uses the deployment names from your resource. Set AZURE_OPENAI_BASE_URL to its complete v1 endpoint, such as https://YOUR-RESOURCE-NAME.openai.azure.com/openai/v1/, and select a deployment that supports Chat Completions. Enter the deployment name as a custom model slug if it does not appear in the model dropdown.
• Mistral Codestral uses a separate key from Mistral La Plateforme.
• Kimi Code subscription keys use kimi_code/; Kimi API credit keys use kimi/. Kimi Code plans are for personal interactive coding-agent use under Kimi's community guidelines.
• QwenCloud Coding Plan keys use qwencloud_coding/; QwenCloud Token Plan keys use qwencloud/. The keys and endpoints are not interchangeable. Coding Plan is for local, personal, interactive coding-agent use under the Coding Plan terms.
• OpenCode Zen and OpenCode Go share OPENCODE_API_KEY but use the explicit opencode_zen/ and opencode_go/ model prefixes.
• For Amazon Bedrock, set BEDROCK_BASE_URL to the URL for the same region as the API key and select one of the listed models.
• Vertex AI uses Google Application Default Credentials instead of an API key. Locally, run gcloud auth application-default login once; service-account files and attached service accounts also work. Set VERTEX_PROJECT_ID, and optionally change VERTEX_LOCATION from its global default.
• Cloudflare requires both its API token and account ID.
• For Ollama Cloud, use the exact model IDs shown in the model picker. Local Ollama uses the separate ollama/ prefix.
• Prefer tool-capable models for coding agents. Local models also need enough context for the agent's system prompt and tool definitions.

Local provider setup

LM Studio

Start LM Studio's local server, load a tool-capable model, and use the model identifier shown by LM Studio with the lmstudio/ prefix. The default URL is http://localhost:1234/v1.

llama.cpp

Start llama-server with its OpenAI-compatible Chat Completions API and enough context for the model. Use the local model ID with the llamacpp/ prefix. LLAMACPP_BASE_URL defaults to http://localhost:8080/v1; FCC accepts either the server root or an explicit /v1 suffix.

Ollama

ollama pull llama3.1
ollama serve

Use the tag shown by ollama list with the ollama/ prefix. OLLAMA_BASE_URL defaults to http://localhost:11434; FCC accepts either the root URL or an explicit /v1 suffix.

Optional model-tier routing

MODEL is the fallback for every request. Select a model for MODEL_FABLE, MODEL_OPUS, MODEL_SONNET, or MODEL_HAIKU to override an individual Claude Code tier; select None to use MODEL.

For example, route Opus to nvidia_nim/nvidia/nemotron-3-super-120b-a12b, Sonnet to open_router/openrouter/free, Haiku to lmstudio/qwen3.5-coder, and keep MODEL on zai/glm-5.2.

Reasoning control

Open Admin UI → Model Config → Reasoning and select the behavior you want.

Selection	Behavior
From client (default)	Use the effort sent by Claude Code, Codex, Pi, OpenCode, Cline, Hermes, DeepSeek Harness, Grok Build, or Muse Code. If none is sent, keep the provider default.
Off	Request reasoning to be disabled.
Low, Medium, High, X-High, or Max	Override the client with the selected reasoning level.
Inherit (Fable, Opus, Sonnet, and Haiku only)	Use the root Reasoning selection.

Providers that do not support a selected control retain their own behavior.

Connect Your Client

For terminal use, start fcc-server, then run fcc-claude, fcc-codex, fcc-pi, fcc-opencode, fcc-cline, fcc-hermes, fcc-dsh, fcc-grok, or fcc-muse. Use the guides below for editor integrations.

Claude Code in VS Code

Install the Claude Code extension. Open VS Code's user settings as JSON and add:

"claudeCode.disableLoginPrompt": true,
"claudeCode.environmentVariables": [
  { "name": "ANTHROPIC_BASE_URL", "value": "http://localhost:8082" },
  { "name": "ANTHROPIC_AUTH_TOKEN", "value": "freecc" },
  { "name": "CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY", "value": "1" },
  { "name": "CLAUDE_CODE_AUTO_COMPACT_WINDOW", "value": "190000" },
  { "name": "DISABLE_AUTOUPDATER", "value": "1" },
  { "name": "DISABLE_FEEDBACK_COMMAND", "value": "1" },
  { "name": "DISABLE_ERROR_REPORTING", "value": "1" }
]

Match the port and authentication token to the Admin UI, then reload the extension.

Codex App

Start FCC, then edit your Codex configuration:

• Windows: %USERPROFILE%\.codex\config.toml
• macOS: ~/.codex/config.toml

Add the matching model-catalog path and replace YOUR_USERNAME.

Windows:

model_catalog_json = "C:/Users/YOUR_USERNAME/.fcc/codex-model-catalog.json"

macOS:

model_catalog_json = "/Users/YOUR_USERNAME/.fcc/codex-model-catalog.json"

Then add the shared FCC settings:

model_provider = "fcc"
model = "nvidia_nim/nvidia/nemotron-3-super-120b-a12b"

[model_providers.fcc]
name = "Free Claude Code"
base_url = "http://127.0.0.1:8082/v1"
wire_api = "responses"

[model_providers.fcc.auth]
command = "fcc-codex"
args = ["--print-proxy-auth-token"]

Match the model and port to the Admin UI. The auth command reads FCC's current proxy token automatically. Restart the Codex App after setup or model changes, then select an FCC model from its model picker.

Codex in VS Code

Install the Codex extension. Create or edit ~/.codex/config.toml (%USERPROFILE%\.codex\config.toml on Windows):

model_provider = "fcc"
model = "nvidia_nim/nvidia/nemotron-3-super-120b-a12b"

[model_providers.fcc]
name = "Free Claude Code"
base_url = "http://127.0.0.1:8082/v1"
wire_api = "responses"

[model_providers.fcc.auth]
command = "fcc-codex"
args = ["--print-proxy-auth-token"]

Match model and the port to the Admin UI. The auth command reads FCC's current proxy token automatically. Restart VS Code after setup or model changes. For WSL-backed Codex, edit the file inside WSL.

Claude Code in JetBrains ACP

Edit the installed Claude ACP configuration:

• Windows: C:\Users\%USERNAME%\AppData\Roaming\JetBrains\acp-agents\installed.json
• Linux/macOS: ~/.jetbrains/acp.json

Set the environment for acp.registry.claude-acp:

"env": {
  "ANTHROPIC_BASE_URL": "http://localhost:8082",
  "ANTHROPIC_AUTH_TOKEN": "freecc",
  "CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY": "1",
  "CLAUDE_CODE_AUTO_COMPACT_WINDOW": "190000",
  "DISABLE_AUTOUPDATER": "1",
  "DISABLE_FEEDBACK_COMMAND": "1",
  "DISABLE_ERROR_REPORTING": "1"
}

Match the port and token to the Admin UI, then restart the IDE.

Claude Code still asks you to log in

If Claude Code asks you to log in after you configure the FCC URL and token, open its state file:

• Windows: %USERPROFILE%\.claude.json
• macOS/Linux/WSL: ~/.claude.json

Merge this property into the existing JSON without removing its other fields:

"hasCompletedOnboarding": true

If the file does not exist, create it with a complete JSON object:

{
  "hasCompletedOnboarding": true
}

Restart Claude Code or the IDE after saving the file.

Optional Integrations

Configure integrations from Admin UI → Messaging, then click Validate and Apply.

Discord bot

1. Create a bot in the Discord Developer Portal.
2. Enable Message Content Intent and invite it with read, send, message-history, and Manage Messages permissions so /clear can remove user prompts.
3. Set Messaging Platform to discord.
4. Enter Discord Bot Token, Allowed Discord Channels, and an absolute Allowed Directory.
5. Apply the settings and restart the server if requested.

Telegram bot

1. Create a bot with @BotFather.
2. Get your numeric user ID from @userinfobot. In groups, grant the bot permission to delete messages.
3. Set Messaging Platform to telegram.
4. Enter Telegram Bot Token, Allowed Telegram User ID, and an absolute Allowed Directory.
5. Apply the settings and restart the server if requested.

Messaging commands

Usage	Behavior
/stats	Show session state.
Standalone /stop	Cancel all work.
Reply with /stop	Cancel only the selected request while other queued requests continue.
Standalone /clear	Reset all FCC state and remove every tracked message in that chat, including user prompts, voice notes, FCC replies, Telegram's online notice, and the clear command itself.
Reply with /clear	Delete the selected message and its literal platform reply subtree while preserving its ancestors and siblings.

Voice notes

Choose the voice backend you want, then re-run the installer with its option.

Voice backend	macOS/Linux option	Windows option
NVIDIA NIM transcription	--voice-nim	-VoiceNim
Local Whisper on CPU or CUDA	--voice-local	-VoiceLocal
Both backends	--voice-all	-VoiceAll
Local Whisper with CUDA 13.0	--voice-local --torch-backend cu130	-VoiceLocal -TorchBackend cu130

The examples below install NVIDIA NIM transcription. To use another backend, replace the final option with the matching one from the table.

macOS/Linux:

curl -fsSL "https://raw.githubusercontent.com/Alishahryar1/free-claude-code/main/scripts/install.sh" | sh -s -- --voice-nim

Windows PowerShell:

& ([scriptblock]::Create((irm "https://raw.githubusercontent.com/Alishahryar1/free-claude-code/main/scripts/install.ps1"))) -VoiceNim

Restart fcc-server. In Admin UI → Messaging → Voice, enable voice notes, select cpu, cuda, or nvidia_nim, and choose the Whisper model. Local gated models need HUGGINGFACE_API_KEY; NVIDIA NIM transcription needs NVIDIA_NIM_API_KEY.

Manage Your Installation

Run fcc-server --version to check the installed version without starting FCC.

Update

Re-run the matching command from Install Or Update.

Uninstall
