Should you build your own GitHub Copilot?
AI coding assistant integrated with GitHub and editors
⌨️ featured in the best vibe coding tools
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.

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.The prompt opens pre-filled in your agent. Review it before running. · this prompt is generated from the build plan · improve it via PR
What would building your own look like?
Install an open-source IDE assistant, connect model APIs or a local model, index the repo, and generate code/edit suggestions.
What you will need
- VS Code/JetBrains extension
- LLM API or local model
- repo indexing
- optional GitHub token
They pay because low-latency completion and repo-aware coding are available in their editor without setup.

Is it cheaper to build or buy GitHub Copilot?
Adjust the numbers: hours to build, your hourly rate, running costs and the subscription price.
Over 24 months, subscribing is cheaper.
Starting hours estimated from the analysis (weekend). Does not price what you give up (support, integrations, security).
Can I rebuild GitHub Copilot?
Kinda. The core of GitHub Copilot is buildable in a weekend with the prompt on this page, but there are real gaps: native GitHub/IDE integration, fast completions. Read the honest list above before committing.
How much does GitHub Copilot cost?
GitHub Copilot costs about $10/mo (Pro, checked 10/20/2026), which is $120 per year.
What do I lose by replacing GitHub Copilot?
Honestly: native GitHub/IDE integration; fast completions; model routing; code review/security features; managed billing; team controls. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to GitHub Copilot?
Yes: OpenCode (A fast local coding agent with no loyalty to any model vendor.) Zed (A fast open editor with completions, chat and agents built in; model usage is separate.) Cline (A code agent in your editor; the model bill is still yours.) All 5 curated free alternatives are at https://viberadar.si/github-copilot/alternatives.
