- 59 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.
- 11 coding agents. One model catalog. Run Claude Code, Codex, Pi, OpenCode, Cline, Hermes, DeepSeek Harness, Grok Build, Muse Code, Aider, or VS Code Chat 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. This works 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.
- Native Code sessions in your browser. Choose a folder and run Codex in the browser with real-time and background support. Freely switch providers/models in the same session. Support for switching harnesses in the same session coming soon!
- 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.

fcc-dshFor DeepSeek Harness Desktop, install and open the app once, then select Connect under Integrations → DeepSeek Harness Desktop in FCC. Keep FCC running while using its models. FCC becomes the default for new sessions. Select Disconnect to remove the connection. Native DeepSeek account features still need a DeepSeek login.
Use DeepSeek Harness 0.2.0-rc.2 or newer. Update the CLI with:
npm install -g @deepseek-ai/dsh@latestFor headless tasks, run fcc-dsh headless "your task". Extra --patch files apply after FCC's settings. After disconnecting Desktop, select another model to continue an existing FCC session. If another DSH setting uses FCC's Desktop credential, Disconnect keeps that credential and reports why.

Provider-specific setup
- OpenAI / ChatGPT uses your ChatGPT subscription rather than an API key. Connect from Providers → OAuth providers → OpenAI / ChatGPT → Connect in the Admin UI and finish signing in through your browser. Restart an already-running agent after connecting.
- Anthropic uses a separately billed API key. Add it under
Providers → Cloud providers → Anthropic → Configure, then choose a discovered
model. Multi-workspace keys also require
ANTHROPIC_WORKSPACE_ID. Messages requests use Anthropic's native tools and the client's thinking controls. FCC local web tools and prompt optimizations apply to other routes. Native requests can fall back only to other Anthropic models. Anthropic tool access and charges apply. - OpenAI API uses a separate Platform API key. Enter it under Providers → Cloud providers → OpenAI API → Configure. The model list may include IDs that cannot handle coding requests. Choose a text-generation model.
- GitHub Copilot uses your signed-in GitHub account and subscription. Install
Copilot CLI 1.0.83
on PATH, then choose Providers → OAuth providers → GitHub Copilot → Connect.
Finish signing in, then select a
github_copilot/<model-id>from the model picker. Available models and quotas depend on your subscription and organization policies. Restart an already-running agent after connecting. - Azure OpenAI uses the deployment names from your resource. Set
AZURE_OPENAI_BASE_URLto its complete v1 endpoint, such ashttps://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 usekimi/. Kimi Code plans are for personal interactive coding-agent use under Kimi's community guidelines. - Alibaba Cloud uses a Model Studio pay-as-you-go key and defaults to Singapore.
For another region or workspace, set
ALIBABA_CLOUD_BASE_URLto its OpenAI-compatible endpoint ending in/compatible-mode/v1. The key and endpoint must use the same region. - QwenCloud Coding Plan keys use
qwencloud_coding/. QwenCloud Token Plan keys useqwencloud/. 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_KEYbut use the explicitopencode_zen/andopencode_go/model prefixes. - For Amazon Bedrock, set
BEDROCK_BASE_URLto 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 loginonce. Service-account files and attached service accounts also work. SetVERTEX_PROJECT_ID, and optionally changeVERTEX_LOCATIONfrom itsglobaldefault. - 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
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.
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.
ollama pull llama3.1
ollama serveUse the tag shown by ollama list with the ollama/ prefix. OLLAMA_BASE_URL defaults to http://localhost:11434.
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.
Reasoning control
Open Admin UI → Model Config → Reasoning and select the behavior you want.
| Selection | Behavior |
|---|---|
| From client (default) | Use the effort sent by your coding agent. 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.
For editor and app integrations, install the client, start FCC, then open Admin UI → Integrations and click Connect on its card.
- Claude Code in VS Code: Install the Claude Code extension.
- VS Code Chat: Install the latest VS Code, connect, and select an FCC model in its built-in Chat model picker.
- Claude Desktop: Install Claude Desktop. Fully quit it before connecting or disconnecting, then reopen it. Disconnect returns to normal Claude sign-in.
- Codex in VS Code and App: Install the Codex extension or Codex App.
- Claude Code in JetBrains ACP: Install Claude Agent in JetBrains AI Assistant and start it once, then click Connect in FCC. Reopen the IDE, select Claude Code (FCC), and start a new chat. After JetBrains updates the agent, restart FCC before starting a new chat. Requires a local IDE in its standard installation locations.
Reload VS Code or restart the app/IDE after connecting. In Codex and Claude Desktop, select an FCC model from the model picker. Reload or restart the client when FCC reports updated settings. Use Disconnect on the same card to remove the integration.
Run FCC on the same computer and in the same user environment as the client you are configuring.

In Admin UI → Messaging → Voice, enable voice notes, select cpu or cuda, and choose the Whisper model. Local gated models need HUGGINGFACE_API_KEY.
Run fcc-server --version to check the installed version without starting FCC.
Stop all running FCC commands, then run:
fcc-updateIf FCC is already up to date, the command stops without running the installer. Otherwise, it shows the installed and available versions before updating. If the version check fails, retry the command.
To reinstall FCC or change optional components while already up to date, run the installer directly.
For local voice support, include --voice-local (macOS/Linux) or -VoiceLocal (Windows), plus your --torch-backend or -TorchBackend option if used.
If your installation does not have fcc-update yet, run the installer once to add it.
