Can I vibecode GitHub Copilot?
// buildable in a weekend, but real gaps stay open
You can use open-source editor agents and local/API models, but Copilot's value is editor integration, model routing, GitHub context, completions, and managed usage.

The moat outweighs the price: rebuilding this is a project, not an evening.
Gioco editoriale: il verdetto dice se un agente può, l’indice se conviene.
What you build
Install an open-source IDE assistant, connect model APIs or a local model, index the repo, and generate code/edit suggestions.
what you need
- VS Code/JetBrains extension
- LLM API or local model
- repo indexing
- optional GitHub token
Very relevant to the site's own audience; verdict is nuanced because the app is partly wrapper, partly platform.
The prompt
A weekend with a coding agent. The gaps that stay are right below, under “what you lose”.
Build me a local-first coding assistant setup to replace GitHub Copilot. Requirements:
- Do not build or train a model. Set up the open-source Continue extension in
VS Code, configured against models I control.
- Chat and edit model: Claude or GPT over API, key referenced from my
environment, never committed. Autocomplete model: a small local coder model
served by Ollama, so completions are free and work offline.
- Deliver the actual Continue config file with both models wired, plus
sensible keybindings for inline edit and chat.
- Enable Continue's codebase indexing for repo-aware answers; document where
the index lives and how to rebuild it.
- Add scripts/ai-review.sh: pipes `git diff` to the API model (key from .env)
and prints a short pre-commit review.
- Everything local except the chat-model API calls; turn off the extension's
telemetry in the config.
- Out of scope: writing an editor extension from scratch, GitHub PR-bot
features, team seat management.
- README: Ollama install and model pull commands, where keys go, and an honest
note that local autocomplete is slower and dumber than Copilot's, that is
the trade for free and private.Prompt generated from the data on this page, not reviewed by hand yet. In English on purpose — it is the language coding agents work best in.
What you lose
- native GitHub/IDE integration
- fast completions
- model routing
- code review/security features
- managed billing
- team controls
Why people still pay
They pay because low-latency completion and repo-aware coding are available in their editor without setup.

model/platform/editor integration

Cline open source (si apre in una nuova scheda) 65.8k ★ Aug 2026 one-click deploy A code agent in your editor; the model bill is still yours. 
Kilo Code open source (si apre in una nuova scheda) 26.7k ★ Aug 2026 one-click deploy One open agent across VS Code, JetBrains and the terminal; inference still has a meter somewhere. 
OpenCode open source (si apre in una nuova scheda) 193.7k ★ Aug 2026 one-click deploy A fast local coding agent with no loyalty to any model vendor. Tabby open source (si apre in una nuova scheda) 33.8k ★ Jun 2026 Docker Copilot-shaped completions and chat, paid for with your own GPU instead of a seat. Zed open source (si apre in una nuova scheda) 88.1k ★ Aug 2026 one-click deploy A fast open editor with completions, chat and agents built in; model usage is separate. Rejected (3) — and why
- Continue (si apre in una nuova scheda) — Acquired by Cursor; the repo is read-only and 2.0.0 is the last release.
- Refact (si apre in una nuova scheda) — The original repo was archived and Refact Cloud was retired in May 2026.
- Roo Code (si apre in una nuova scheda) — The extension shut down and the repo was archived on May 15, 2026.
Who has already built it
Starting from here is still vibecoding: the prompt is for when you want it exactly your way.
- Continue (opens in a new tab) — Open-source coding assistant extension that connects to local or hosted models. (alive)
