GoCodeo

GoCodeo is a VS Code extension that wraps an AI coding agent around the full build-test-debug loop, with three core modes: BUILD (real-time code generation across 25+ frameworks with one-click Vercel deploy and Supabase wiring), ASK (an in-IDE chat companion with code/image context and @Web search), and TEST (sub-30-second generation of production-ready test suites plus AI failure analysis). It is model-pluggable, routing prompts to Claude 3.5/3.7 Sonnet, Gemini 2.5 Pro, DeepSeek-R1, GPT-4o, or o3-mini depending on the task.

The pitch is aimed at full-stack JavaScript and Python developers who want a Cursor-style flow without leaving VS Code, and who care about the deploy step rather than just code completion. The Supabase + Vercel hooks are the real differentiator versus generic copilots, and the test generation mode is meaningfully ahead of what stock GitHub Copilot ships. There is a free tier via the VS Code Marketplace; the product claims 25,000+ engineers on the platform but does not publish detailed paid pricing on the homepage.

There is no public API, no self-hostable version, and no open-source codebase — this is a closed extension tied to the VS Code ecosystem. JetBrains and Neovim users are out of scope, and teams with strict data-residency requirements should check the model-routing terms before adopting.
