What FauxPilot is

FauxPilot is free, MIT-licensed software for running a locally hosted alternative to the GitHub Copilot server. It provides an OpenAI-compatible API and a REST endpoint for client connections, although the compatible API is not fully implemented. Documentation also explains how to configure the official VS Code Copilot plugin to use a FauxPilot server, while noting that some plugin functions may not work exactly and tokenizer differences can create overlong requests. The server uses Salesforce CodeGen models with NVIDIA Triton Inference Server and the FasterTransformer backend. Setup documentation lists Python-only and multi-language models from 350M to 16B parameters. A setup script downloads and converts the selected model, then Docker Compose starts the server. Running it requires an NVIDIA GPU with Compute Capability 6.0 or higher; documented model memory needs range from 2GB to 32GB. The MIT License permits use, copying, modification, distribution, and sale under its conditions. The project points users to a wiki and discussion forum, but provides no formal support or warranty. The wiki covers usage, troubleshooting, and extensions, with limited contents.

Who it suits

It suits developers who want to operate code completion locally and connect compatible clients or the VS Code Copilot plugin. Users need Docker, NVIDIA GPU hardware, and comfort managing a self-hosted server.

What it does well

  • Free open-source MIT-licensed software
  • Runs models locally
  • Offers REST and OpenAI-compatible connections
  • Supports models from 350M to 16B parameters
  • Provides VS Code plugin setup guidance

What to know first

  • Requires an NVIDIA GPU
  • OpenAI-compatible API is incomplete
  • Some plugin functions may break
  • No formal support or warranty

Verdict

FauxPilot offers local code completion with selectable CodeGen models and self-hosted deployment. Hardware, Docker setup, incomplete API compatibility, and limited support make it a technical option rather than a turnkey service.
